Creating Fireworks Sugar Cookie Bars is simple and fun! Just follow these easy steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish or line it with parchment paper for easy removal.
2. Mix Dry Ingredients: In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
3. Cream Butter and Sugar: In a large bowl, beat the softened butter and granulated sugar together until light and fluffy, about 2-3 minutes.
4. Add Egg and Extracts: Beat in the egg, vanilla extract, and almond extract (if using) until well combined.
5. Combine Mixtures: Gradually add the dry ingredients to the wet mixture, mixing until just combined. Be careful not to overmix.
6. Fold in Sprinkles: Gently fold in the rainbow sprinkles, ensuring an even distribution throughout the dough.
7. Spread in Baking Dish: Transfer the dough to the prepared baking dish, smoothing it out into an even layer.
8. Top with Extra Sprinkles: Sprinkle additional rainbow sprinkles on top for an extra festive touch.
9. Bake: Bake in the preheated oven for 20-25 minutes, or until the edges are lightly golden and a toothpick inserted in the center comes out clean.
10. Cool: Remove from the oven and let the bars cool in the pan for 10-15 minutes before transferring them to a wire rack to cool completely.
11. Slice and Serve: Once cooled, slice into squares or rectangles. Enjoy your Fireworks Sugar Cookie Bars!
