Serves: 18-20 cupcakes
What You’ll Need
Creating perfect confetti cupcakes starts with gathering the right ingredients. The key to getting those beautiful rainbow specks throughout your cupcakes is using the right type of sprinkles and quality baking basics.
For the cupcakes:
- 2 1/2 cups all-purpose flour
- 2 1/2 teaspoons baking powder
- 1/2 teaspoon salt
- 1/2 cup unsalted butter, softened to room temperature
- 1 3/4 cups granulated sugar
- 4 large eggs, room temperature
- 2 teaspoons pure vanilla extract
- 1 1/4 cups whole milk, room temperature
- 1/2 cup rainbow sprinkles (use the long, thin jimmies style)
For the vanilla buttercream frosting:
- 1 cup unsalted butter, softened
- 4 cups powdered sugar
- 1/4 cup heavy cream or milk
- 2 teaspoons vanilla extract
- 1/4 teaspoon salt
- Additional rainbow sprinkles for decoration
Getting Your Kitchen Ready
Start by preheating your oven to 350 degrees and lining two standard muffin pans with colorful paper cupcake liners. Make sure all your ingredients are at room temperature, as this helps everything blend together smoothly and creates the fluffiest texture. Take your butter and eggs out of the refrigerator about an hour before you plan to start baking.
Making the Perfect Cupcake Batter
In a medium bowl, whisk together the flour, baking powder, and salt. Set this dry mixture aside for now. In a large mixing bowl, use an electric mixer to cream the softened butter and sugar together for about 3-4 minutes until the mixture becomes light and fluffy. This step is crucial for creating tender cupcakes, so don’t rush it.
Add the eggs one at a time, beating well after each addition. Pour in the vanilla extract and mix until everything is well combined. The mixture might look a little lumpy at this point, but that’s perfectly normal.
Now comes the important part: alternating the dry ingredients with the milk. Add about one-third of your flour mixture to the butter mixture and mix on low speed until just combined. Pour in half the milk and mix gently. Add another third of the flour mixture, then the remaining milk, and finally the last of the flour. Mix each addition just until you can’t see any more streaks of flour or milk.
Adding the Rainbow Magic
Here’s where the magic happens. Gently fold in the rainbow sprinkles by hand using a large spoon or rubber spatula. Be gentle here because over-mixing can cause the colors from the sprinkles to bleed into your batter, turning it gray instead of keeping those pretty rainbow specks. Fold just until the sprinkles are evenly distributed throughout the batter.
Baking Your Cupcakes
Using a cookie scoop or large spoon, divide the batter evenly among your prepared cupcake liners, filling each about two-thirds full. This is the perfect amount to get nice, domed tops without overflow. Bake for 18-20 minutes, or until a toothpick inserted into the center comes out clean or with just a few moist crumbs.
Let the cupcakes cool in the pans for about 5 minutes, then carefully transfer them to a wire cooling rack. This is important because cupcakes that are too warm will melt your frosting right off.
Creating Fluffy Buttercream Frosting
While your cupcakes cool completely, make your buttercream frosting. In a large bowl, beat the softened butter with an electric mixer until it’s light and fluffy, about 3-4 minutes. Gradually add the powdered sugar, one cup at a time, beating well after each addition.
Pour in the heavy cream, vanilla extract, and salt, then beat the mixture on high speed for 2-3 minutes until it becomes smooth and creamy. If your frosting seems too thick, add a tablespoon more cream. If it’s too thin, add a bit more powdered sugar.
Decorating Your Confetti Cupcakes
Once your cupcakes are completely cool, it’s time for the fun part. You can spread the frosting on with a knife for a rustic look, or use a piping bag fitted with a large star tip to create beautiful swirls. Fill your piping bag with frosting and pipe generous swirls on top of each cupcake, starting from the outside and working your way to the center.
Immediately sprinkle more rainbow sprinkles on top of the frosted cupcakes while the frosting is still soft so they stick perfectly. Press them lightly into the frosting if needed.
Storage and Make-Ahead Tips
These cupcakes taste best the day they’re made, but you can store them covered at room temperature for up to three days. If you need to make them ahead, you can bake the cupcakes up to two days in advance and store them unfrosted in an airtight container. Make the frosting the day you plan to serve them for the best taste and texture.
For longer storage, unfrosted cupcakes can be wrapped tightly and frozen for up to three months. Just thaw them at room temperature before frosting.
Troubleshooting Common Issues
If your cupcakes turn out dense instead of light and fluffy, the most common cause is over-mixing the batter or using ingredients that weren’t at room temperature. If the sprinkle colors bleed into your batter, try coating your sprinkles in a light dusting of flour before folding them in, or switch to nonpareil sprinkles which tend to bleed less.
If your cupcakes overflow during baking, you’ve filled the liners too full. Stick to about two-thirds full for perfect results every time.
Fun Variations to Try
While classic confetti cupcakes are perfect as they are, you can have fun with variations. Try using different colored sprinkles to match party themes, like pink and white for a princess party or red, white, and blue for patriotic celebrations. You can also experiment with different extract flavors in both the cake and frosting – almond extract creates a delicious bakery-style flavor.
These Confetti Cupcakes bring pure happiness to any gathering. The combination of tender vanilla cake studded with colorful sprinkles and topped with creamy buttercream frosting creates a treat that’s both nostalgic and special. Whether you’re celebrating a birthday, hosting a party, or just want to brighten someone’s day, these cupcakes deliver smiles with every single bite.
