Ingredients: 1 1/2 cups all-purpose flour. 1 1/2 tsp baking powder. 1/4 tsp salt. 1/2 cup unsalted butter, softened. 1 cup granulated sugar. 2 large eggs. 1 tsp vanilla extract. 1/2 cup whole milk. 1/2 cup rainbow sprinkles.
Instructions: Start by heating the oven to 350F 175C. You can line a muffin tin with cupcake liners. Whisk the flour, baking powder, and salt together in a bowl. Put away. Mix the softened butter and sugar in a different bowl until the mixture is light and fluffy. One at a time, add the eggs and beat well after each one. Add the vanilla extract and mix well. Slowly add the dry ingredients to the wet ones, mixing them in with the milk every so often. Start with the dry ingredients and end with the milk. Don't mix any further than that. Add the rainbow sprinkles slowly. Fill each muffin cup about two thirds of the way to the top with cupcake batter. In a hot oven, bake for 18 to 20 minutes, or until a toothpick stuck in the middle comes out clean. After the cupcakes have cooled in the pan for a few minutes, move them to a wire rack to cool all the way down. For the sprinkle packets you make yourself: Just put a bunch of different colored sprinkles in small ziplock bags and let your guests make their own cupcake toppings. Once the cupcakes are completely cool, you can frost them however you like and add the DIY sprinkle packets on top for a fun holiday touch.
