• 5 Tbsp unsalted butter softened (71g)• ⅔ cup granulated sugar (130g)• 2 Tablespoons light brown sugar firmly packed (25g)• 2 teaspoons vanilla extract• 1 ⅓ cups cake flour (150g)• ¼ teaspoon baking powder• ⅛ teaspoon table salt• 3 Tablespoons sprinkles I like to use a mix of nonpareils and jimmies but one or the other would work fine
With electric mixer on medium-low, gradually add flour mixture to butter mixture until combined. Mixture will be very dry, but if you pinch it with your fingers it should cling together.
Bake crumbs on 315F (155C) for 10-12 minutes. Allow to cool completely on baking sheet then use as desired over cakes, cupcakes, cookies, or even just enjoy by the handful.
