Sheet Pan Halloween Confetti Cookie Bars

Directions

1. Set your oven to 350°F and lightly coat an 18x13-inch sheet pan with cooking spray.
2. In a stand mixer or large bowl with a hand mixer, beat the softened butter and light brown sugar until the mixture is light and fluffy.
3. Add the eggs and vanilla extract, mixing until well incorporated.
4. Add the flour, baking powder, and salt, mixing on low speed first then increasing. Beat just until combined, scraping the bowl's sides as needed.
5. Gently mix in the white chocolate chips, semi-sweet chocolate chips, and 1 cup of the Halloween sprinkles until evenly distributed.
6. Transfer the dough to the prepared pan and use your hands to press it evenly across the entire surface.
7. Sprinkle the remaining 2-3 tablespoons of sprinkles on top, adjusting the amount to your liking.
8. Bake for 20 to 23 minutes, until the edges turn golden and the center is just set.
9. Allow the cookie bars to cool completely, then cut into squares and serve. Store leftovers in an airtight container for several days.
