Instructions
Preheat and Prep
Preheat your oven to 350°F (175°C). Line a 12-cup muffin pan with paper liners.
Coat the Sprinkles
In a small bowl, toss the rainbow jimmies with 1 tablespoon of flour until evenly coated. This prevents them from sinking to the bottom of the cupcakes.
Combine Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
Cream Butter and Sugar
In a large bowl using a hand mixer or stand mixer, beat the softened butter and granulated sugar together on medium speed until light and fluffy, about 2-3 minutes.
Add Eggs and Vanilla
Add the eggs one at a time, beating well after each addition. Beat in the vanilla extract.
Alternate Dry and Wet
With the mixer on low speed, add about one-third of the dry ingredients, mixing just until combined. Add half of the milk, mixing until incorporated. Repeat with another third of the dry, the remaining milk, and finally the last of the dry. Mix just until no streaks of flour remain—do not overmix.
Fold in Sprinkles
Gently fold the floured sprinkles into the batter with a spatula until evenly distributed. Fold just a few times—you don’t want the colors to bleed.
Fill the Liners
Divide the batter evenly among the cupcake liners, filling each about ⅔ full.
Bake
Bake for 18-22 minutes, until a toothpick inserted into the center of a cupcake comes out clean or with a few moist crumbs. The tops should spring back when lightly touched.
Cool
Let the cupcakes cool in the pan for 5-10 minutes, then transfer to a wire rack to cool completely before frosting.
Make the Vanilla Buttercream
In a large bowl, beat the softened butter on medium speed until creamy and smooth, about 2-3 minutes. Gradually add the powdered sugar, one cup at a time, beating on low until combined.
Add the heavy cream, vanilla extract, and salt. Beat on medium-high speed for 2-3 minutes until the frosting is light, fluffy, and spreadable.
Frost the Cupcakes
Once the cupcakes are completely cool, frost them using a piping bag fitted with your favorite tip (like a large star tip for a classic swirl).
Add Sprinkles
Immediately top with a generous shower of rainbow jimmies so they stick to the frosting.
Serve and Store
Serve at room temperature. Store any leftovers in an airtight container at room temperature for up to 3 days.
Pro-Tips for Funfetti Cupcake Greatness
- Use Rainbow Jimmies: Not nonpareils or sanding sugar. Jimmies hold their shape and color best during baking
- Flour Your Sprinkles: Tossing them in a little flour prevents sinking and keeps them suspended throughout the cupcake
- Use Clear Vanilla: If you want the purest white batter, clear vanilla extract is your friend. Regular vanilla works too, but will slightly tint the batter
- Don’t Overmix After Adding Sprinkles: Fold gently to prevent the colors from bleeding into the batter
- Add Sprinkles Immediately After Frosting: They’ll stick best to fresh, wet frosting.
