Preheat your oven to 350 degrees Fahrenheit. Grease a 12 inch pizza pan with a cold stick of butter, using a paper towel afterwards to even it out.
In a large mixing bowl combine the flour, baking powder and salt. Set aside.
2 1/2 cups all purpose flour, 1/2 teaspoon baking powder, 1/2 teaspoon salt
In a large bowl with a hand mixer or in the bowl of a stand mixer with the paddle attachment, cream together the butter and sugar. Beat for three to six minutes until light and fluffy ensuring that you beat plenty of air into the butter.
1 1/2 cups sugar, 14 tablespoons butter
Add the eggs, one at a time. Then add the vanilla extract and the almond extract.
2 large eggs, 1 teaspoon vanilla extract, 1 teaspoon almond extract
Add in the flour mixture. Mix on low just until the flour starts to become incorporated. Then turn the mixer to high just long enough for the flour mixture to be fully incorporated, being careful not to over mix.
Gently stir in the sprinkles until well combined.
1/2 cup sprinkles
Press the dough into the pizza pan.
Bake for 20 to 25 minutes or until the edges of the cookie cake just begin to to turn golden brown.
Remove from the oven and allow to cool completely before piping on the frosting.
