Preheat your oven to 350°F (175°C) and line a 9x13 inch baking pan with parchment paper, leaving some overhang for easy removal.
In a separate bowl, whisk together the flour, baking soda, baking powder, and salt until combined. Set aside.
In a large bowl, cream the softened butter and granulated sugar together using an electric mixer on medium speed until light and fluffy, about 3-4 minutes.
Add the eggs one at a time, mixing well after each addition. Then, mix in the vanilla and almond extracts.
Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix.
Gently fold in the rainbow sprinkles, making sure they are evenly distributed throughout the dough.
Spread the cookie dough evenly into the prepared baking pan, smoothing the top with a spatula.
Bake in the preheated oven for 20-25 minutes, or until the edges are lightly golden and a toothpick inserted into the center comes out clean.
Allow the bars to cool completely in the pan on a wire rack.
In a small bowl, whisk together powdered sugar, milk, and vanilla extract until smooth. Adjust the consistency by adding more milk or powdered sugar if needed.
Once the bars are completely cooled, remove them from the pan using the parchment overhang. Spread the icing evenly over the top and sprinkle additional rainbow sprinkles for decoration.
Cut into squares or rectangles and serve. Enjoy your colorful and sweet Funfetti Sugar Cookie Bars!
Notes
Allow the bars to cool completely before icing for best results.
