Preheat the oven to 350°F. Line two baking sheets with parchment paper.
Beat the butter and sugar in a large bowl with an electric mixer until slightly creamy, about 2 minutes.
Add the eggs and egg yolk one at a time, scraping down the bowl between additions.
Add the vanilla and almond extract and beat to combine.
Add the baking powder, baking soda, and salt, and beat to combine.
Add the cake mix and flour and beat until combined.
Add the Christmas sprinkles and mix on low speed just until evenly distributed.
Use a 2-ounce cookie scoop to form the dough into balls.
Place 4 dough balls on each baking sheet.
Bake 10-12 minutes. The edges should be slightly golden and the middle set. They might still seem soft in the middle but it should not look dough-y. They will set up as they cool.
Cool on the sheet for 5 minutes, then move to a rack to cool completely.
