Chocolate Chip Cookie Dough Brownies

Today’s cookie is another old Bake-Off recipe. The original used a boxed brownie mix (made with eggs, oil and water) as the base. This version is similar, but with a scratch brownie base.

These are very easy to make, but you’ll have to be patient because there’s a lot of cooling time involved. Today, I halved the recipe and made them in an 8 inch pan. Since this is such a fun recipe to share, I recommend making a full 13×9 inch batch.

If you have a box of brownie mix around, the original version is cheaper and much easier to make. You can save a lot of time and concentrate on the filling and topping. The only thing I don’t like about the original recipe’s filling is that it didn’t seem like enough, which is why I did it 1 1/2 times in my version below.

Don’t let the length of the ingredient list scare you. It’s mostly stuff you probably have around the house and many of the ingredients in the first part are just repeated down below.

Recipe type: Dessert
Cuisine: American
Serves: 24
Brownie Base:
  • 2 sticks (16 tablespoons) unsalted butter
  • 2 1/4 cups granulated sugar
  • 1 1/4 cups Dutch process or Hershey's "Dark" cocoa
  • 1 teaspoon salt - if using regular salted butter, decrease to 1/2 tsp.
  • 1 teaspoon baking powder
  • 4 large eggs
  • 1 tablespoons vanilla
  • 1 1/2 cups all purpose flour
  • 3/4 cup semi-sweet chocolate chips
  • 12 tablespoons unsalted butter, softened
  • 1/2 scant teaspoon salt (omit if using salted butter)
  • 3/4 cup brown sugar, packed
  • 6 tablespoons granulated sugar
  • 3 tablespoons milk
  • 1 tablespoon vanilla
  • 1 1/2 cups all purpose flour, lightly spooned and swept
  • 1 1/4 cup semi-sweet chocolate chips
  • 1 1/2 teaspoons butter or vegetable oil
  • 1/4 cup lightly toasted chopped walnuts*
  1. Preheat oven to 350 degrees F. Line a 13x9 inch pan with Release foil or parchment.
  2. In a 3 quart saucepan, melt butter over medium heat. Stir in sugar and cook gently, stirring constantly, for about 1 minute or until sugar melts and mixture takes on a nice sheen. Add cocoa and stir until smooth. Remove from heat. Let cool for about 5 minutes, then stir in the salt and baking powder. Stir in the eggs (one by one), then add the vanilla, flour and chocolate chips (make sure batter is cool before adding chips). Spread batter in pan and bake for 25-30 minutes or until brownies are set. Let brownies cool on a rack for at least a half hour.
  3. Prepare filling. Beat together butter, salt (if using), both sugars, milk and vanilla. Add flour and stir until flour is incorporated. Spread this mixture over cooled brownies and place in refrigerator for about 30 minutes to help firm up dough.
  4. In a microwave-safe bowl or in a double boiler, melt chocolate and butter. If using a microwave, combine chocolate and butter and microwave on high for 30 seconds. Stir and repeat until melted. Spread melted chocolate mixture over cookie dough. Sprinkle walnuts over top. Allow chocolate to set, then lift from pan and cut into bars.

    Love cookie dough. Seems like I’ve made something like this before but it wasn’t so good…I think that chilling it would have helped a LOT! May have to try this sometime. Thanks for the recipe.
