The first thing you want to do is bake your flour. Yep, place 1/2 cup of all-purpose flour onto a clean baking sheet and cook the flour for 5 minutes at 350 degrees Fahrenheit to kill off bacteria. Then let it cool.
Now, in a medium-sized bowl, beat together 1/4 cup unsalted room temperature butter and 1/4 cup granulated sugar using an electric hand mixer.
Now add in 1/2 teaspoon vanilla extract, 1 tablespoon milk, 1/8 teaspoon salt, along with the flour and rainbow sprinkles if you love them. Then Enjoy!
