Description
Thick, chewy, and loaded with chocolate chips, these rich peanut butter cookie bars are a dessert everyone will crave.
Ingredients
1 cup unsalted butter, softened
1 cup creamy peanut butter
1½ cups light brown sugar, packed
½ cup granulated sugar
1 large egg + 1 egg yolk
2 tsp vanilla extract
2¾ cups all-purpose flour
1 tsp cornstarch
½ tsp baking powder
¼ tsp salt
2 tbsp milk
2 cups semi-sweet chocolate chips
Instructions
Preheat oven to 350°F (175°C). Line a 9×13-inch pan with parchment paper or lightly grease.
In a large bowl, cream butter, peanut butter, brown sugar, and granulated sugar until smooth.
Add egg, egg yolk, and vanilla; mix well.
In another bowl, whisk flour, cornstarch, baking powder, and salt.
Gradually combine dry ingredients with the wet mixture.
Stir in milk and fold in chocolate chips.
Spread the batter evenly in the prepared pan.
Bake for 35 minutes, or until edges are golden and a toothpick comes out with a few moist crumbs.
Let cool completely before cutting into 24 bars.
Notes
Add chopped nuts or swap chocolate chips for white or peanut butter chips for variation.
Sprinkle flaky sea salt on top before baking for a sweet-salty contrast.
