Step 1

To heat treat the flour, microwave it in a bowl for four 20-second intervals, stirring in between each one. Let the flour cool for 5-10 minutes. Alternatively, spread the flour on a clean baking sheet and bake at 350°F for 5 minutes, stirring halfway to eliminate any bacteria.

Step 2

In a medium-sized bowl, use a rubber spatula or an electric mixer to cream together the softened butter and sugar. Then mix in the vanilla extract until smooth and creamy.

Step 3

Add the cooled, heat-treated flour and mix gently until a thick sugar cookie dough forms. If it's too thick, add a splash of milk or water.

Step 4

Gently fold in the sprinkles or other mix-ins of your choice. Enjoy right away or store in an airtight container in the refrigerator for 3-4 days.
