1-First Step: Prepare the Dry Ingredients Whisk together 1 3/4 cups flour, 1 1/2 cups sugar, 1/2 tsp baking powder, 1/4 tsp baking soda, and 1/2 tsp salt in a medium bowl. This ensures even distribution for consistent funfetti cupcakes. For gluten-free, use the substitute here.

2-Second Step: Cream the Butter and Wet Ingredients In a large bowl, beat 1/2 cup softened butter until creamy, about 2 minutes with an electric mixer. Add 2 eggs one at a time, beating well after each. Mix in 1 tbsp vanilla. For vegan adaptations, prepare flax eggs ahead and use vegan butter.

3-Third Step: Combine Wet and Dry Mixtures Alternately add dry ingredients and 3/4 cup milk to the butter mixture, starting and ending with dry. Beat on low until just combined, about 1 minute. Avoid overmixing to keep vanilla cupcakes tender. Gently fold in 1/2 cup sprinkles by hand.

4-Fourth Step: Fill and Bake the Cupcakes Scoop batter into liners, filling 2/3 full. Bake for 18-22 minutes until a toothpick comes out clean. Cool in tins for 5 minutes, then transfer to a wire rack. This method works for low-calorie versions too, just monitor bake time.

5-Fifth Step: Make the Vanilla Buttercream Frosting Beat 1 cup softened butter until smooth. Gradually add 4 cups sifted powdered sugar, 2 tsp vanilla, and 2-3 tbsp cream. Whip on high for 3 minutes until fluffy. Pipe or spread on cooled funfetti cake cupcakes.

6-Final Step: Decorate and Serve Top with extra sprinkles for funfetti birthday cupcakes appeal. Serve at room temperature. These homemade funfetti cupcakes from scratch stay fresh for days. Pair with coffee for busy parents or pack for students.
