  • Total Time: 55 minutes
  • Yield: 12 bars 1x

Ingredients

Scale
  • 4 cups chopped fresh or frozen rhubarb (thawed and dried)
  • 2 cups old-fashioned rolled oats
  • 1 and 1/2 cups brown sugar, packed
  • 2 cups all-purpose flour
  • 1 cup cold butter, diced
  • 1/2 teaspoon salt
  • Optional: 1/2 teaspoon cinnamon or 1/4 teaspoon nutmeg
  • Optional: 1 teaspoon vanilla extract
  • Optional: 1/2 cup chopped pecans or walnuts

Instructions

  1. Preheat oven to 350°F (175°C).
  2. Chop rhubarb into uniform 1/2-inch pieces; if using frozen, thaw completely and pat dry.
  3. In a large mixing bowl, combine oats, brown sugar, flour, salt, and optional cinnamon or nutmeg.
  4. Using fingers or pastry cutter, work in diced cold butter until mixture resembles coarse crumbs.
  5. Press 2/3 of the oat mixture firmly into a greased 8×8-inch baking pan.
  6. Evenly layer chopped rhubarb over the oat base. Optionally sprinkle with vanilla extract.
  7. Scatter remaining oat mixture over rhubarb as topping.
  8. Bake for 30-35 minutes until golden brown and fragrant.
  9. Cool completely before slicing for clean squares.

Notes

Dry rhubarb thoroughly to prevent soggy bars. Chill bars before slicing for neat results. Can substitute half strawberries for a fruit variation.
