What You’ll Need for Confetti Sprinkle Cupcakes
- 1 and 3/4 cups (207g) cake flour (spooned & leveled)
- 3/4 teaspoon baking powder
- 1/4 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 cup (8 Tbsp; 113g) unsalted butter, softened to room temperature
- 1 cup (200g) granulated sugar
- 3 large egg whites, at room temperature
- 2 teaspoons pure vanilla extract
- 1/2 cup (120g) full-fat sour cream, at room temperature
- 1/2 cup (120ml) whole milk, at room temperature
- 1/2 cup (80g) rainbow sprinkles (plus extra for garnish)

How to Make Confetti Sprinkle Cupcakes
- Preheat the oven to 350°F (177°C). Line a 12-cup muffin pan with cupcake liners. Line a second pan with 2 liners—this recipe makes about 14 cupcakes. Set aside.
- Whisk the dry ingredients: In a bowl, combine the cake flour, baking powder, baking soda, and salt. Set aside.
- Cream the butter and sugar: Using a handheld or stand mixer with a paddle attachment, beat the butter and sugar on high speed until smooth and creamy, about 2 minutes. Scrape down the sides of the bowl as needed.
- Add wet ingredients: Beat in the egg whites and vanilla extract on medium-high speed until combined. Then, mix in the sour cream. Scrape down the bowl again.
- Combine dry and wet ingredients: With the mixer on low speed, add the dry ingredients until just incorporated. Slowly pour in the milk while mixing on low. Do not over-mix.
- Fold in sprinkles: Gently and slowly whisk in the rainbow sprinkles. The batter will be slightly thick.
- Fill the liners: Pour or spoon the batter into the liners, filling only 2/3 full to prevent overflow.
- Bake: Bake for 19-22 minutes, or until a toothpick inserted in the center comes out clean. For mini cupcakes, bake for 11-13 minutes at the same temperature.
- Cool completely: Allow the cupcakes to cool in the pan for a few minutes, then transfer to a wire rack to cool completely before frosting.
- Frost and decorate: Frost the cooled cupcakes with vanilla buttercream or your choice of frosting. Garnish with extra sprinkles if desired.
- Store: Leftover cupcakes keep well covered tightly in the refrigerator for up to 3 days.
Fun Frosting & Topping Ideas
While vanilla buttercream is a classic choice, feel free to get creative with your frosting! Try cream cheese frosting for a tangy twist or chocolate ganache for a rich, decadent finish. For a pop of color, mix in gel food coloring to match your theme. Don’t forget to add extra sprinkles on top for a festive touch!
Perfect Pairings for Your Cupcakes
These Confetti Sprinkle Cupcakes are perfect for parties or afternoon treats. Serve them with a glass of cold milk or a cup of hot coffee for a delightful combination. For a dessert spread, pair them with mini cookies or fruit skewers to balance the sweetness.
Storage Tips for Freshness
Store leftover cupcakes in an airtight container in the refrigerator for up to 3 days. If you’d like to enjoy them later, freeze unfrosted cupcakes in a freezer-safe bag for up to 2 months. Thaw at room temperature and frost before serving for the best texture.
Time-Saving Hacks for Busy Bakers
Short on time? Use a boxed cake mix as a base and add sprinkles to the batter for a quick version. You can also prepare the batter the night before and bake it fresh in the morning. For frosting, pre-made options work in a pinch—just jazz them up with extra sprinkles!
Common Questions Answered
Can I use all-purpose flour instead of cake flour? Yes, but the texture will be slightly denser. For a closer substitute, replace 2 tablespoons of all-purpose flour with cornstarch per cup. Can I use whole eggs instead of egg whites? Yes, but the cupcakes may be slightly less light and fluffy. Stick to egg whites for the best results!
