Peanut Butter Chocolate Chip Cookie Bars Recipe

Preheat oven to 350 degrees F. Line a 9 x 13-inch baking pan with non-stick foil.

In a small bowl, whip butter and sugar until combined and creamy. Beat in flour and salt until mixture becomes crumbly, but evenly moist. Press evenly into the bottom of the baking pan.

Combine chocolate chips and peanut butter chips in a bowl and stir until combined. Spread half of the mixed chips on top of the bottom layer, pressing gently to embed slightly into the dough.

In a medium bowl, beat eggs, sweetened condensed milk , and vanilla extract until combined. Spread evenly on top of chips and cookie layer.

Bake until browned and semi-firm in the center, about 20 to 25 minutes. Place on wire rack. (Top will sink slightly as it cools.) While still warm, sprinkle top with remaining mixed chocolate and peanut butter chips. Let cool. If you prefer a frosting, wait a few minutes, then use a spatula to gently spread the melted chips to form a frosting. Cool completely before cutting into cookie bars .

Yield: 24 to 36 cookie bars, depending on cut size
