Betty's Crunchy Brownie Bars

A goodie Betty shared with the group at our annual rughooking retreat. Recipe originally came from the back of a Duncan Hines brownie box, but she decided she liked a Betty Crocker boxed brownie mix better. Cook time does not include time to cool. I thought the oatmeal layer might detract from the brownie, but it was a wonderful compliment.

Ingredients Nutrition

  • Crunchy Layer

  • 34 cup flour, sifted
  • 14 teaspoon baking soda
  • 14 teaspoon salt
  • 1 12 cups quick-cooking rolled oats
  • 34 cup brown sugar
  • 34 cup butter, melted
  • Brownie Layer

  • 1 (21 1/4 ounce) package brownie mix (Betty Crocker Hershey's Triple Chunk Supreme)
  • 3 tablespoons water
  • 12 cup vegetable oil
  • 2 eggs
  • Frosting

  • 1 12 unsweetened chocolate squares (1 1/2 ounces)
  • 3 tablespoons butter or 3 tablespoons margarine
  • 2 14 cups confectioners' sugar, sift if lumpy
  • 1 12 teaspoons vanilla
  • 3 tablespoons hot water


  1. For crunchy layer, combine flour, soda and salt; stir in oats and brown sugar.
  2. Add the 3/4 cups melted butter and pat mixture in bottom of an ungreased 13 x 9-inch baking pan.
  3. Bake at 350°F for 5 minutes; at this time it will not be completely baked.
  4. While bottom layer is in the oven, prepare brownies as directed on package.
  5. Spread batter in pan over crunchy layer.
  6. Return to oven and bake for approximately 25-30 minutes until done (do not over bake).

  8. In a small saucepan melt together chocolate and the 3 tablespoons butter.
  9. Remove from heat; immediately add confectioners' sugar, vanilla and 2 tablespoons hot water.
  10. Stir until smooth; add remaining tablespoon hot water to make a soft, pourable consistency.
  11. Spread over brownies while frosting is still hot; let set until firm.
  12. Cut into bars.

Excellent! These are rich, delicious, and easy. They slice cleanly so look pretty served on a tray or right out of the pan. I ended up cutting them a little larger than bite size for a dessert tray of asst bar cookies. Thank you for sharing a recipe I will use again!

Thanks for sharing this recipe. This recipe is a nice change from the same old brownie.

These are a nice, more-than-the-sum-of-its-parts dessert to have at home to take to someone's house. I used a jarred frosting that I wasn't too happy with; the next time I make these I will use a homemade frosting. And maybe some toasted coconut in the oatmeal layer!
