Preheat the oven to 350°F (180°C).
In a bowl, cream together the butter and sugar until light and fluffy. I typically mix for about 2 minutes in my stand mixer.
1 ½ cups (333g) salted butter, softened, 1 ½ cups (345g) granulated sugar
Add in the eggs, cake batter flavoring and a few drops of pink food coloring. Once mixed, add in the flour and baking powder. Mix until thoroughly combined.
3 eggs, 1 ½ tsp cake batter flavoring, pink food coloring, 4 ½ cups (684g) all-purpose flour, 3 tsp baking powder
Divide the dough into 3 Tbsp portions and roll into a ball and flatten slightly before arranging on a parchment or silicone lined cookie sheet.
Bake for 9-11 minutes or until the centers of the cookies have puffed up and are no longer glossy.
While the cookies are cooling, make the frosting by whipping the butter, cream cheese, and vanilla until smooth.
1/4 cup (56g) butter, softened, 8 oz cream cheese, room temperature, 2 tsp vanilla
Add the powdered sugar, one cup at a time. Add in the pinch of salt and then add milk a few tsp at a time until you've reached your desired consistency.
4 cups (428g) powdered sugar, 1 pinch salt, milk or heavy cream, to thin
Put the finished frosting into a piping bag fit with a round piping tip. Pipe the frosting onto the still warm cookie in a spiral, starting in the center and working your way out and top immediately with Christmas Sprinkles.
