In the mixing bowl of a standing mixer, add the 18 Tablespoons of butter, 1 cup of powdered sugar, 2 cups of flour, 1 teaspoon of almond extract, ½ teaspoon vanilla extract, and 2 Tablespoons of sprinkles.
Using the paddle attachment, mix on low speed for 1-2 minutes. Note: The dough will be crumbly at this point. Place the crumbled shortbread dough onto a sheet of parchment paper on a generously sized work surface. Use your hands to carefully shape the dough into a large dough ball, turning it several times to ensure an even shape.
Using a rolling pin, roll the dough into a rectangle shape ensuring it is around ¼ to ½ inch thick.
From there, pick up the parchment paper and put it in a 13x9 pyrex dish or on a cookie sheet.
Place the dish/cookie sheet in the refrigerator and allow the shortbread dough to chill for 1 hour. Remove the chilled dough from the refrigerator and place the dish on the counter.
Using you favorite cookie cutters, press into the dough. Line a large cookie sheet with parchment paper and place each cut out on the cookie sheet.
Preheat the oven to 350℉. Bake the cookies for 14-15 minutes until slightly golden on the bottoms.
Remove the cookie sheet from the oven. Using a spatula, move the shortbread cookies to a cooling rack.
