Confetti Sprinkle Cupcakes Ingredients
Here's everything you need to make these bakery-style Confetti Sprinkle Cupcakes at home.
See Recipe Card Below This Post For Ingredient Quantities
- Cake flour: This is the foundation of the recipe and creates the softest, most tender crumb. Don't skip it or substitute it with all-purpose if you want truly fluffy cupcakes.
- Baking powder and baking soda: These work together to give the cupcakes a light, airy rise.
- Salt: Balances the sweetness and enhances all the other flavors.
- Unsalted butter: Adds richness and helps create a soft, melt-in-your-mouth texture. Make sure it's softened to room temperature so it creams properly with the sugar.
- Granulated sugar: Sweetens the cupcakes and helps create a tender crumb when creamed with the butter.
- Egg whites: Using only the whites keeps the cupcakes light and fluffy without weighing them down. Make sure they're at room temperature for the best texture.
- Pure vanilla extract: Brings that classic bakery vanilla flavor to every bite.
- Full-fat sour cream: Adds moisture and a subtle tang that makes the cupcakes taste richer. Room temperature sour cream mixes in more easily.
- Whole milk: Thins the batter just enough and keeps the cupcakes moist. Whole milk works better than low-fat for flavor and texture.
- Rainbow sprinkles: The star of the show. Use jimmies-style sprinkles, not nonpareils, because nonpareils bleed color into the batter and turn it gray.
- Vanilla buttercream or frosting of choice: Top these with your favorite frosting. A classic vanilla buttercream is perfect, but cream cheese frosting or chocolate buttercream work beautifully too.
How to Make Confetti Sprinkle Cupcakes
This Confetti Sprinkle Cupcakes comes together quickly and bakes up perfectly every time.
Preheat your oven: Set your oven to 350°F (177°C) and line a 12-count muffin pan with cupcake liners. Prepare a second pan with 2 additional liners for the extra batter.
Mix the dry ingredients: In a medium bowl, whisk together the cake flour, baking powder, baking soda, and salt until evenly combined. Set this aside.
Cream the butter and sugar: Using a handheld or stand mixer fitted with a paddle attachment, beat the softened butter and granulated sugar on high speed for about 2 minutes. The mixture should look light, fluffy, and almost pale in color.
Add the egg whites and vanilla: Scrape down the sides and bottom of the bowl, then add the egg whites and vanilla extract. Beat on medium-high speed until everything is smooth and well combined.
Mix in the sour cream: Beat in the sour cream until it's fully incorporated into the batter. The mixture will look thick and creamy.
Combine the dry ingredients: With the mixer on low speed, add the dry ingredients and mix until just combined. Don't overmix or the cupcakes will turn out dense.
Add the milk: Slowly pour in the whole milk while the mixer runs on low speed. Mix just until the batter is smooth and the milk is incorporated.
Fold in the sprinkles: Gently fold or whisk in the rainbow sprinkles by hand. The batter will be slightly thick but still pourable.
Fill the liners: Spoon the batter into the prepared cupcake liners, filling each one about two-thirds full. This gives the cupcakes room to rise without spilling over.
Bake: Bake for 19 to 22 minutes, or until a toothpick inserted into the center of a cupcake comes out clean. The tops should look set and spring back lightly when touched.
Cool completely: Let the cupcakes cool in the pan for a few minutes, then transfer them to a wire rack to cool completely before frosting. Frosting warm cupcakes will cause the frosting to melt and slide off.
Frost and garnish: Once the cupcakes are completely cool, frost them with vanilla buttercream or your preferred frosting. Add extra rainbow sprinkles on top for a festive finish.
Store properly: Keep leftover cupcakes tightly covered in the refrigerator for up to 3 days.
Ingredient Substitutions
Cake flour: If you don't have cake flour, you can make a substitute by measuring 1 and ¾ cups of all-purpose flour, removing 3 and ½ tablespoons, and replacing it with 3 and ½ tablespoons of cornstarch. Sift it together a few times. The texture won't be quite as soft, but it'll still work.
Sour cream: Plain Greek yogurt or full-fat buttermilk can be used in place of sour cream. The cupcakes will still be moist, though the flavor will be slightly different.
Whole milk: You can use 2% milk if needed, but whole milk gives the best flavor and moisture.
Egg whites: If you want to use whole eggs instead, you can use 2 large whole eggs. The cupcakes will be slightly denser and less fluffy.
Rainbow sprinkles: Stick with jimmies-style sprinkles. Nonpareils will bleed and turn your batter an unappealing gray color.
Equipment For Confetti Sprinkle Cupcakes
You don't need any fancy tools to make these Confetti Sprinkle Cupcakes, just a few basic baking essentials.

Storage and Make-Ahead Tips
These Confetti Sprinkle Cupcakes store beautifully and can be made ahead to save time on party day.
Room temperature: Unfrosted Confetti Sprinkle Cupcakes can be stored in an airtight container at room temperature for up to 2 days.
Refrigerator: Once frosted, store the cupcakes tightly covered in the refrigerator for up to 3 days. Let them sit at room temperature for 15 minutes before serving for the best flavor and texture.
Freezer: Freeze frosted or unfrosted Confetti Sprinkle Cupcakes in an airtight container or freezer bag for up to 2 to 3 months. Thaw them overnight in the refrigerator before serving.
Make-ahead: Bake the cupcakes 1 day ahead and store them covered at room temperature. You can also make the frosting a day ahead and keep it in the refrigerator until you're ready to use it.
Serving Suggestions
These Confetti Sprinkle Cupcakes are perfect for celebrations, but they're also delicious as an everyday treat.

Expert Tips
Use room temperature ingredients: Cold eggs, butter, and sour cream won't mix together as smoothly, and you'll end up with a lumpy batter. Let everything sit out for about 30 minutes before you start baking.
Don't overmix the batter: Once you add the dry ingredients, mix just until everything is combined. Overmixing develops the gluten in the flour and makes the cupcakes tough and dense.
Cool completely before frosting: If you frost warm Confetti Sprinkle Cupcakes, the frosting will melt and slide right off. Be patient and let them cool all the way down.
Store properly: Keep frosted Confetti Sprinkle Cupcakes in the refrigerator to prevent the frosting from spoiling, especially if you're using buttercream made with butter or cream cheese.
FAQ
What makes cupcakes soft and fluffy?
Using cake flour instead of all-purpose flour is the biggest factor. Cake flour has less protein, which makes the crumb softer and more tender. Room temperature ingredients, proper creaming of butter and sugar, and not overmixing the batter also help create that light, fluffy texture. My daughter Emily always asks me to make these instead of box mix because they're so much softer.
Can I use all-purpose flour instead of cake flour for cupcakes?
You can, but the texture won't be as soft and delicate. If you need to substitute, remove 3 and ½ tablespoons of flour from each cup of all-purpose flour and replace it with 3 and ½ tablespoons of cornstarch. Sift it together a few times to blend it well. It's not quite the same as real cake flour, but it's the closest substitute.
Why use egg whites in cupcakes?
Egg whites create a lighter, fluffier texture because they don't contain the fat from the yolks. The result is a cupcake that's airy and tender instead of dense and heavy. If you prefer, you can use 2 whole eggs instead, but the cupcakes will be a bit more cake-like and less fluffy.
How do you keep cupcakes moist?
Using full-fat dairy like sour cream and whole milk keeps Confetti Sprinkle Cupcakes moist and tender. Don't overbake them, either. As soon as a toothpick comes out clean, take them out of the oven. Store them in an airtight container to prevent them from drying out, and if you're making them ahead, refrigerate them after frosting to lock in moisture.
