Layer one: Cream 1/2 cup margarine or butter, 1/2 cup peanut butter, 1/2 cup granulated sugar, 1/2 cup packed brown sugar and 1 egg. Sift together 1 1/4 cup flour, 1/2 teaspoon baking powder, 3/4 teaspoon soda and 1/4 teaspoon salt. Add to creamed mixture. Divide into three parts and press into the bottoms of three 8-by-8-inch pans. You can make layer one ahead of time and refrigerate until ready to bake. Bake at 350 degrees for 13 minutes or until golden brown.
For each pan, mix the following layers:
· Layer two: Combine scant 3/4 cup sweetened condensed milk, 1 tablespoon butter and 3/4 cup chocolate chips in a microwave-safe bowl and microwave on medium-high for 1 minute. Remove from microwave and stir until smooth. Set aside 1/3 cup. Spread the remaining mixture over baked crust (layer one). Return to oven and bake 6 minutes.
