Blondies II Recipe
- 3 1/2 cups all-purpose flour
- 2 1/4 teaspoons baking powder
- 3/4 teaspoon salt
- 3/4 cup butter, softened
- 1 1/2 cups packed brown sugar
- 3/4 cup white sugar
- 3 eggs
- 1 egg yolk
- 2 teaspoons vanilla extract
- 6 tablespoons peanut butter
- 2 cups semisweet chocolate chips
- 1/2 cup butter, softened
- 1 cup peanut butter
- 3 cups confectioners' sugar
- 1/3 cup milk
- Preheat oven to 350 degrees F (175 degrees C). Grease a 9×13 inch baking dish. Sift together the flour, baking powder and salt; set aside.
- In a large bowl, cream together 3/4 cup of butter, brown sugar and white sugar until light and fluffy. Beat in the eggs and yolk one at a time, then stir in the vanilla and 6 tablespoons peanut butter. Blend in the sifted ingredients and stir in the chocolate chips. Press the mixture evenly into the prepared pan.
- Bake in the preheated oven for 25 to 30 minutes, or until a toothpick inserted into the center comes out with moist crumbs. Cool completely before frosting.
- To make the frosting, mix the remaining 1/2 cup of butter and 1 cup peanut butter together in a medium bowl. Mix in the confectioners sugar until smooth, then gradually stir in milk until a spreadable consistency is reached. Cut, serve and enjoy!
