Brownie Brittle Recipe

Preheat oven to 350°F. Line a baking sheet with a silicone mat or parchment paper lightly sprayed with baking spray.

Combine butter, sugar, and vanilla in a large bowl; mix until well incorporated. Add egg white and blend well.

Mix together flour, cocoa powder, baking soda, and salt. Add dry ingredients to the butter mixture and mix for about 1 minute or until smooth.

Using a spatula, spread a thin layer of batter on the prepared baking sheet into an 11x8-inch rectangle. (You want it thin, but not transparent.)

Bake in the preheated oven for 15 minutes. Remove from oven and quickly sprinkle brittle with chocolate chips. Return to the oven and bake for 7 to 10 more minutes.

Remove baking sheet from the oven. Transfer brownie brittle to a wire rack to cool. Cut brownie brittle into pieces before it cools completely and becomes crispy, or break it apart once completely cool. Store in an airtight container for 7 days.
