Step 1

Preheat the oven to 350°F. Bake the flour on a baking sheet lined with parchment paper for approximately 10 minutes, or until the temperature of the flour reaches 160°F. Stir the flour halfway through and allow it to cool completely. Sift the flour through a fine-mesh sieve.

Step 2

Soften the butter in the microwave for 20-30 seconds. In a large mixing bowl, combine the butter, and sugar and beat until creamy.

Step 3

Add the heat-treated flour, salt, vanilla extract, and 1 tablespoon of milk. Beat together until the dough starts to form. Add additional milk as needed until the dough reaches your desired consistency. Mix in the sprinkles.
