Best Sprinkles for Confetti Cupcakes

Use jimmies-style rainbow sprinkles for the best confetti effect. If you prefer to avoid artificial dyes, choose dye-free or naturally colored sprinkles; they’ll still add color without the extra coloring agents.

Substitutions and Variations

To make the recipe gluten-free, use a 1:1 gluten-free flour blend. Swap sour cream for Greek yogurt for similar moisture. Use dairy alternatives in place of milk if needed, and customize sprinkles to suit dietary preferences or event colors.

How to Make Confetti Cupcakes

These cupcakes are straightforward and beginner-friendly. Follow these steps for reliable results.

Preheat the oven to 350°F (177°C) and line a 12-cup muffin tin with liners or use silicone liners.

In a large bowl, cream together the softened butter and sugar with a stand mixer or hand mixer until light and fluffy. Add the egg, sour cream, and vanilla, mixing until combined.

In a separate bowl, whisk the flour, baking powder, baking soda, and salt. Add the dry ingredients to the wet in portions, alternating with the milk. Start and end with the dry ingredients, mixing on low until just combined.

Fold in the rainbow sprinkles gently so the colors don’t bleed. Fill the cupcake liners about halfway with batter and add a few extra sprinkles on top if desired.

Bake 15–18 minutes, until the tops spring back when touched and a toothpick inserted in the center comes out clean or with a few crumbs. Transfer cupcakes to a cooling rack and cool completely before frosting.

Hot Tip: Add sprinkles to the tops right before serving if you want to prevent color bleed into the frosting when storing.

How to Make Buttercream Frosting

For a smooth, pipeable vanilla buttercream:

  • Cream the softened unsalted butter and vanilla with a hand mixer or stand mixer until smooth.
  • Add powdered sugar in 1/2 cup increments, mixing between additions, until the frosting reaches your desired sweetness and thickness.
  • Add heavy cream and mix until the buttercream is smooth but holds its shape well for piping.
  • Scoop into a piping bag fitted with a star tip and pipe onto room-temperature cupcakes. Finish with extra sprinkles.

Tips for Success

  • Bring butter and eggs to room temperature before mixing so they combine evenly.
  • Mix on low speed and avoid overmixing to keep cupcakes tender.
  • Add the dry ingredients gradually for an even batter.

How to Store Leftover Confetti Cupcakes

Store frosted cupcakes in an airtight container in the refrigerator for up to five days. Unfrosted cupcakes can be stored at room temperature in an airtight container for a day or refrigerated for longer storage. To save time, bake ahead and frost just before serving.

FAQ

What is the secret to super moist cupcakes?

Including sour cream or Greek yogurt in the batter helps cupcakes stay moist. Mixing on low speed and avoiding overmixing also preserves a tender crumb.

Will sprinkles bleed into buttercream frosting?

Dye from sprinkles can bleed over time. To avoid this, add extra sprinkles to the tops right before serving or apply them after removing refrigerated cupcakes from the fridge.
