Did you know you can turn your fridge into a science lab with just yogurt and cornstarch? That’s right—this edible yogurt silly putty recipe is part snack, part sensory fun! Perfect for little hands and curious minds, it’s a taste-safe alternative to traditional slime and a great way to bond with your kids. Whether you’re a parent, teacher, or just a putty enthusiast, you’re going to love this bouncy, colorful creation. Let’s dig in!
What Is Edible Yogurt Silly Putty?
Okay, so let’s talk about this edible yogurt silly putty—because when I first heard about it, I totally thought it was a Pinterest fail waiting to happen. Yogurt? And cornstarch? But you know what? It’s now my favorite go-to for rainy days, playdates, and even those “I’m bored” meltdowns.
Let me break it down. This stuff is like a magical mash-up of edible slime and DIY sensory play. You mix up two ingredients—yogurt and cornstarch—and you get this stretchy, squishy dough that feels oddly satisfying to poke, squish, and stretch. It’s completely taste-safe too, which makes it the best kind of non-toxic slime for toddlers. Especially if your little one is still in the “lick-everything” phase (been there, cleaned that).
Why I Love It (And You Might Too)
Honestly, the first time I made it, it was mostly because I didn’t want to deal with glue or Borax. You’ve probably Googled how to make slime without glue—this is your answer. And no worrying about those chemical ingredients either. This stuff is gentle, even for sensitive skin. Plus, if it ends up in your kid’s mouth? It’s just yogurt and cornflour. Safe slime for toddlers and your sanity.
There’s something calming about mixing and kneading it, like a little kitchen-based stress reliever. Even I get sucked into the squishiness. And I’ve noticed it really helps my kiddo focus—kind of like a homemade fidget toy but cooler because you made it yourself.
Real Talk: My First Try Was a Mess
Not gonna lie, the first time I made it I added way too much yogurt. The result? Goop city. But I learned quick—add the cornstarch slowly, knead it like you’re making bread, and boom: perfect edible putty texture. Pro tip? Greek yogurt is thicker and works best. The regular stuff gets soupy fast.
The Cool Part? It’s a STEAM Activity in Disguise
Yup, it’s not just a craft—it’s kitchen chemistry. Mixing, experimenting, adjusting… it’s basically an edible STEM activity that feels like playtime. My kid felt like a scientist, and I got to sneak in a little learning without making it feel like school. Win-win.
Whether you’re trying to avoid store-bought slime disasters or just want a creative sensory activity, edible yogurt silly putty is a total game-changer. No weird ingredients, no mess you can’t handle, and no “don’t eat that!” drama.
So, if you’re on the hunt for an easy slime recipe without glue or a non-toxic play dough alternative, this is it.
Ingredients You’ll Need
Okay, let’s talk supplies. One of the best parts about making this edible yogurt silly putty? You probably already have most of it sitting in your kitchen. No last-minute craft store run or sketchy Amazon ingredients. Just plain ol’ pantry staples—and a little optional glittery flair if you’re feeling extra.
Here’s the basic lineup:
- 1 cup of yogurt — I usually use vanilla Greek yogurt. It’s thicker, which makes the putty stretch better and last longer. Flavored yogurt works too, but skip anything with chunks unless you like lumpy slime (gross).
- 1 to 2 cups of cornstarch — Also known as cornflour in some places. This is the real MVP of the recipe. It’s what gives the silly putty its soft, squishy feel.
- Optional add-ins — Food coloring (for a pop of color), sprinkles (for texture), or edible glitter (for pizzazz). Totally unnecessary, but kids eat up the visual fun—sometimes literally.
Quick Tool Check
You’ll need a small mixing bowl, a spoon, and either a wax paper sheet or a play mat for less mess. Trust me on the mat. The first time I skipped it, my kitchen counter looked like a powdered sugar warzone. Lesson learned.
Real-Life Mistake Alert
I once thought, “Why not double the yogurt to make more putty?” Spoiler: I ended up with slime soup. The trick is to start with equal parts yogurt and cornstarch, then gradually add more cornstarch until it feels right. It should feel soft and stretchy, not sticky or wet.
If you mess it up, don’t panic—this stuff is super forgiving. Too wet? Add cornstarch. Too dry? A spoonful more yogurt. Easy fix.
Why These Ingredients Work
What I love is how simple and non-toxic this recipe is. No glue, no weird chemicals, no stress. It’s safe slime for toddlers and totally edible—though it doesn’t exactly taste amazing (my kid tried it and said, “Meh, it’s like glue yogurt”). Not a glowing review, but hey, no emergency dentist trips either.
And don’t feel like you have to use Greek yogurt. If you only have regular yogurt, that works too—just expect a little more kneading. Want to keep it dairy-free? Try coconut yogurt. I haven’t tested every variation, but experimenting is half the fun.
So before you dive into the messy magic, grab these simple ingredients. The fewer the steps, the more time you have for giggles and squishing.
Step-by-Step Instructions
Alright, you’ve got your yogurt, you’ve got your cornstarch, maybe even some rainbow sprinkles—and now it’s go time. Making edible yogurt silly putty is ridiculously simple, but I’ve messed it up enough times to know that a few small tweaks can save you from goopy disaster.
Here’s how to make edible slime that’s actually fun to play with:
1. Scoop the Yogurt
Start with 1 cup of yogurt in a small mixing bowl. Greek-style yogurt works best—it’s thick and makes a firm dough. If you’re using something thinner, like regular vanilla yogurt, just know you’ll probably need more cornstarch to balance it out.
Side note: my kid loves strawberry yogurt, but I once used a brand with fruit chunks and it got… lumpy. Not exactly a win in the safe sensory activity department.
2. Add 1 Cup of Cornstarch
Dump in 1 cup of cornstarch and stir slowly. I say “slowly” because if you go full speed like I did the first time, it turns into a powdered snowstorm. Not cute. You’re aiming for a smooth, thick paste at this stage.
If it’s still super sticky, that’s normal. We’re not done yet.
3. Adjust the Texture
This is the part where you play slime scientist. Keep adding cornstarch a little at a time—about a tablespoon per scoop—until the dough becomes soft, stretchy, and not sticky. You’ll know it’s right when it pulls away from the bowl and you can grab a handful without it oozing between your fingers.
Pro tip: If it crumbles when you stretch it, you’ve gone too far. No big deal—just mix in a spoonful of yogurt and knead again.
4. Add Fun Extras (Optional)
Here’s where the fun begins. A few drops of food coloring can turn your plain putty into rainbow magic. Want to feel like a Pinterest champ? Toss in some edible glitter or themed sprinkles.
Just be warned: red food coloring stains. My fingertips were pink for a solid two days. Gloves are your best friend here.
5. Knead the Dough
Use your hands to knead the dough until it’s totally smooth and stretchy. This is hands-on play at its best—and honestly, it feels kind of like therapy. It’s soft, cool, and just the right kind of squishy. If it’s still sticking to your hands, sprinkle in a little more cornstarch.
I once made the mistake of giving it to my son before kneading. Big mistake. It glued itself to the carpet like some sort of dairy-based alien.
6. Play!
Once the texture is perfect, you’re done! You’ve made your own DIY edible slime and it’s ready for poking, pulling, and molding. Spread out some wax paper or use a silicone mat to keep cleanup easy.
Just don’t leave it out too long—it dries up fast. And while it’s edible, it’s not exactly tasty, so maybe have a real snack nearby too.
Tips for Best Results
So you’ve mixed your yogurt and cornstarch, but it’s not quite the magical stretchy slime you were promised. Don’t worry—I’ve been there. The first few times I made this, I either ended up with goop that glued itself to everything or a dry crumble that fell apart like old playdough. Here’s how to fix those rookie mistakes and level up your DIY sensory play game.
Use Thick Yogurt
This one’s huge. If you’re using a watery or low-fat yogurt, the mixture tends to be way too sticky. Thick Greek yogurt is the gold standard—it gives you that perfect doughy stretch without needing to dump in a whole bag of cornstarch. If Greek yogurt isn’t an option, just drain off any extra liquid first. Trust me, it makes a difference.
Go Slow With the Cornstarch
I know, I know—when the slime is sticking to your hands like marshmallow fluff, it’s tempting to dump in a bunch of cornstarch all at once. But resist. Too much, and you’ll end up with dry, crumbly bits that refuse to hold together. Instead, add it one tablespoon at a time and knead as you go. Your patience will pay off.
Also… wear dark clothes at your own risk. Cornstarch gets everywhere.
Food Coloring = Fun + Stains
Want to make your putty pop? Add a few drops of food coloring. Just keep in mind, red and blue are notorious for staining skin and countertops. I had a Smurf finger situation once that lasted all weekend. Now I throw on some disposable gloves if I’m going for bold colors—or I just let the kid rock a psychedelic handprint for a couple days.
Sprinkles or Glitter? Yes, But…
Adding edible glitter or sprinkles is a total win for visual flair. But they can change the texture. I found that nonpareils tend to melt a bit and make the dough softer, while sugar crystals hold up better. So if you want crunch-free play, stick to the glitter.
Also, avoid anything too big. My son once insisted on adding chocolate chips. Let’s just say we had a “melty disaster” that looked like a crime scene. Keep it small and dry.
Work on a Washable Surface
Do yourself a favor and play on a wax paper sheet, silicone mat, or even inside a shallow baking tray. First time I made this, we used the kitchen table directly—and yeah, yogurt putty is surprisingly good at sneaking into the wood grain. I spent more time cleaning than we did playing.
Don’t Skip the Knead
If your slime feels off, just knead it longer. This isn’t optional. The heat from your hands + a few minutes of squishing = way better texture. It might feel too wet or too dry at first, but give it a good 2–3 minutes of kneading and it usually comes together like magic.
These small tweaks seriously make a huge difference in how fun (or frustrating) your edible slime-making experience is. And once you get the hang of it? You’ll be knocking out perfect batches in under 10 minutes, no sweat.
How to Store and Reuse
Alright, let’s be real—after all that mixing, kneading, and glitter-adding, the last thing you want is to toss your perfect putty in the trash after one play session. I made that mistake the first time, and my kid looked at me like I just canceled Christmas. So here’s the deal on how to store homemade slime—yes, even the edible kind!
Airtight Is Everything
The trick to keeping your edible yogurt silly putty soft is airtight storage. Seriously, don’t just throw it in a sandwich bag and hope for the best (guilty). You’ll wake up to a rock-solid chunk of dried goop. I use a little plastic food container with a tight-sealing lid. Mason jars work too if you’re feelin’ fancy.
Pro tip: Wrap the putty in a piece of wax paper before sealing it up—it helps hold the moisture in without turning it to mush.
Keep It Cool
Because we’re using real yogurt, this isn’t the kind of thing you can leave out overnight. Always pop it in the refrigerator after playtime. It should stay fresh for up to 2 days. Any longer and you’ll start to notice it gets sticky or weird-smelling—time to toss it.
I made the mistake of storing it in the pantry once (total brain fog day), and… yeah. Yogurt + room temp = moldy slime surprise. Definitely not the fun sensory play we were going for.
Reviving Old Slime (Sometimes Works)
If your silly putty starts to dry out but hasn’t gone bad, you can sometimes bring it back to life. Add a teaspoon of yogurt and knead it like you’re making dough. It won’t be exactly like new, but it’ll be good enough for one more round of poking and stretching.
Honestly though, I usually just treat this stuff like a one-to-two-day play project. We make it, we play with it, and then we move on. Low stress, no guilt.
Label It (Especially If It Looks Like Food)
This one’s a random mom tip: if you’re storing the putty in a container that looks like yogurt, label it. I once caught my husband with a spoon halfway to his mouth. He thought it was leftover strawberry Greek. Yeah… that would’ve been an unpleasant surprise.
So if you want to get the most out of your DIY slime recipe, storing it right makes all the difference. A little prep = way more play.
Fun Variations to Try
Once you nail the basic edible yogurt silly putty, trust me—you’re gonna want to start getting creative. My kid? Total sprinkle addict. We’ve made everything from “unicorn sparkle goo” to “Halloween monster dough.” This stuff is like a blank canvas for any DIY sensory play idea you can dream up.
1. Rainbow Slime
This is always a hit. Divide your putty into 3–5 small bowls and add a different drop of food coloring to each. Knead separately (use gloves if you don’t want tie-dye hands), then swirl them together gently to make a rainbow slime that looks like candy but plays like a dream.
Pro tip: Don’t over-mix or you’ll get a sad brown blob. Swirling is the move.
2. Holiday-Themed Putty
We’ve done green + red putty with peppermint extract around Christmas, orange + black sprinkles for Halloween, even pastel colors for Easter. Holiday-themed sensory play makes the whole thing feel festive—and the photos are total Pinterest bait.
One time we added mini candy hearts for Valentine’s Day and ended up with what looked like slime soup. Cute idea, poor execution. Stick with dry toppings!
3. Glow-in-the-Dark Version
Yup, you can make glow in the dark slime that’s still edible. There’s this thing called edible glow powder (found it on Etsy). Mix it in with the cornstarch and BAM—late-night sensory magic. Kids will lose their minds over this one.
We turned the lights off in the bathroom and had a whole “mad scientist” play session. 10/10 fun, zero regrets.
4. Scented Slime
Try adding safe scents like vanilla extract, lemon juice, or cocoa powder. It makes the sensory experience even more fun—and for toddlers, engaging multiple senses is a big developmental plus.
Just remember, the better it smells, the more tempting it is to eat. So set expectations. (“Yes it smells like chocolate, no it’s not dessert.”)
5. Sprinkle Party Slime
Okay, this one’s purely for the aesthetic. Mix in some edible glitter or rainbow nonpareils and call it birthday slime. It’s the perfect activity for a kid’s party—super cheap, no baking, and bonus: they get to take it home in little containers like party favors.
Just don’t store sprinkle slime too long. The sugar melts and gets weird after about a day.
Honestly, once you know how to make the base slime, the possibilities are endless. It’s like building your own slime lab right at the kitchen table—and your kids will totally think you’re a genius.
There you have it—edible yogurt silly putty that’s fun to make, safe to play with, and surprisingly relaxing to squish. Whether you’re trying to entertain a toddler, host a slime party, or just sneak some science into playtime, this DIY sensory play recipe hits all the right notes.
It’s quick, mess-friendly (mostly), and doesn’t require anything fancy. And hey, even when it flops a little, it’s still a blast. My kitchen’s been covered in cornstarch more times than I can count, and I’d do it all over again just to see that “Whoa!” look on my kid’s face when the dough stretches just right.
So next time you’re stuck indoors or need a low-prep activity, remember this homemade edible slime recipe. Try a new variation. Get messy. And don’t forget to snap a pic of those rainbow swirls or glittery masterpieces.
