Instructions

• Preheat the oven to 375°F and place a rack in the center. Spray a 15x10-inch jelly roll pan with non-stick spray.
• In a medium bowl, whisk together the all-purpose flour, white whole wheat flour, baking soda, and kosher salt. Set the flour mixture aside.
• In the bowl of an electric mixer, add the room-temperature unsalted butter and dark brown sugar. Beat on medium-high for about 2 minutes, until the mixture is light and fluffy.
• Add the vanilla bean paste and mix until incorporated.
• Add the eggs one at a time, mixing and scraping down the bowl as needed so each egg is fully incorporated before adding the next.
• Reduce the mixer speed to low and gradually add the flour mixture, mixing just until the dough is combined and no dry streaks remain. Scrape down the sides and bottom of the bowl as needed.
• Fold in the peanut butter Nestle DelightFulls and the mini dark chocolate chips with a spatula until evenly distributed.
• Transfer the dough to the prepared jelly roll pan and press it into an even layer using an offset spatula or the back of a spoon.
• Bake on the center rack for about 25 minutes, or until the edges and top are lightly browned and a toothpick inserted near the center comes out with a few moist crumbs.
• Remove the pan from the oven and let the cookie bars cool completely in the pan on a wire rack.
• Once cooled, cut into bars and serve.
