How to Make Crunchy Brownie Bars

  1. Preheat oven to 350°F (175°C). Grease a 9x13 inch baking pan.
  2. **Crunchy Layer:**
  3. In a medium bowl, combine 1 ½ cups all-purpose flour, 1 teaspoon baking soda, and ½ teaspoon salt.
  4. Stir in 2 cups rolled oats and ¾ cup packed light brown sugar.
  5. Add ½ cup (1 stick) melted unsalted butter and mix until well combined.
  6. Press the mixture firmly into the bottom of the prepared baking pan.
  7. Bake for 10 minutes.
  8. **Brownie Layer:**
  9. While the crunchy layer bakes, prepare your favorite brownie mix according to package directions. (This recipe uses Duncan Hines Fudgy Brownies as an example – adjust ingredients based on your chosen mix). If using Duncan Hines Fudgy brownies, use the ingredients listed on the package as a guide.
  10. Once the crunchy layer is partially baked, remove it from the oven. Pour the brownie batter evenly over the crunchy layer.
  11. Bake for an additional 35-40 minutes for cake-like brownies, or 40-45 minutes for fudgy brownies. Do not overbake!
  12. Let the brownies cool completely in the pan before frosting.
  13. **Frosting:**
  14. In a small saucepan over low heat, melt 6 ounces semi-sweet chocolate chips and ¼ cup (½ stick) unsalted butter.
  15. Remove from heat and stir in 2 cups powdered sugar, 1 teaspoon vanilla extract, and 2 tablespoons hot water until smooth.
  16. Add 1 tablespoon more hot water if needed to reach a pourable consistency.
  17. Spread the frosting evenly over the cooled brownies.
  18. Refrigerate for at least 30 minutes to allow the frosting to set.
  19. Cut into bars and enjoy!
