Preheat your oven to 350°F/175°C. Line your baking sheet with parchment paper.
In a medium bowl, whisk together the flour, baking powder and salt together. Set aside.
In the bowl of a stand mixer fitted with the paddle attachment, beat the butter for 1 minute until soft and creamy.
Add your sugar and beat on medium-high for 3 minutes until light and fluffy.
Add your egg, egg yolk, almond extract and vanilla extract, then beat until it is well combined.
Add your dry ingredients and beat on low, stop as soon as the flour is combined.
Pour in your sprinkles and fold by hand/
Scoop out the dough into 1 ½ tablespoon balls and roll in the extra granulated sugar. Chill for 20 minutes or up to overnight. If chilling overnight, keep the cookie dough balls in an airtight container or wrap in plastic wrap.
Bake 4-6 at a time (depending on the size of your baking sheet!) for 11 minutes. While you're baking those, keep the others in the fridge. The cookies will continue cooking when they’re taken out of the oven and the middle will set and crack.
