What you will need

This recipe uses 7 simple ingredients that you can find at any grocery store:

  • 1.5 cups all purpose flour
  • 0.75 cup granulated sugar
  • 0.5 cup unsalted butter softened
  • 2 large eggs
  • 0.5 cup whole milk
  • 2 teaspoons vanilla extract
  • 1.5 teaspoons baking powder

Step by step instructions

Step 1: Make the Cupcake Batter

Beat the softened butter and sugar together until pale and fluffy about 3 minutes. Add eggs one at a time beating well after each then mix in the vanilla. Alternately add the flour with baking powder and milk in three additions beginning and ending with flour and mixing until just smooth.

Step 2: Fill and Bake

Line a 12 cup muffin tin with colorful cupcake liners and fill each liner about two thirds full with batter. Bake in a preheated 350 degree oven for 16 to 18 minutes until a toothpick inserted in the center comes out clean and tops spring back when lightly touched.

Step 3: Make Buttercream Frosting

Beat 1 cup softened butter with 3 cups powdered sugar a tablespoon of milk and a teaspoon of vanilla extract until smooth silky and fluffy. Divide the frosting and tint with different food coloring gels for a rainbow effect if desired.

Step 4: Frost and Decorate

Allow cupcakes to cool completely on a wire rack before frosting. Use a piping bag fitted with a star tip to swirl frosting on each cupcake or simply spread with a knife. Top generously with rainbow sprinkles and any other fun decorations kids want to add.

Easy substitutions

Missing an ingredient? Here are some swaps that work perfectly:

  • whole milk → any plant based milk such as oat or almond milk works perfectly in this recipe
  • unsalted butter in batter → neutral flavored oil such as canola oil for an extra moist cupcake texture

Common mistakes to avoid

Watch out for these pitfalls that can affect your results:

  • Overmixing the batter after adding the flour which develops too much gluten and results in dense tough cupcakes
  • Frosting the cupcakes while they are still warm which causes the buttercream to melt and slide right off the top
