I came up with this recipe for a friend who wanted to make a birthday cake for her husband, who loves chocolate chip cookies. The goal was to have a texture more like cake than traditional cookie bars, but still keep the cookie taste.
- ½ cup unsalted butter (softened)
- 1 cup plus 2 tbs sugar
- ½ cup brown sugar
- ½ cup peanut butter
- 4 eggs (separated)
- 1½ tsp vanilla
- ¼ cup dark rum
- 2⅓ cups pastry or all-purpose flour
- 2 tsp baking powder
- 1 tsp salt
- 12 oz bittersweet chocolate chips
- Preheat oven to 350°F.
- Grease and flour a 12 inch square baking pan.
- Cream together butter, 1 cup sugar, and ½ cup brown sugar.
- Add peanut butter, egg yolks, vanilla, and rum.
- Beat well.
- In separate bowl, whisk together flour, baking powder, and salt.
- Add in batches to wet ingredients until just combined.
- Beat egg whites until opaque.
- Gradually add remaining 2 tbs sugar while continuing to beat until stiff.
- Mix ¼ of egg whites into batter and combine well (the whites will deflate).
- Gently fold in remaining whites and chocolate chips.
- Bake for 40-50 minutes, until toothpick comes out clean.
