- Cake flour – Recommended for the lightest crumb. Spoon and level when measuring or use a scale. If using all-purpose flour, see recipe notes for the substitution method.
- Butter – Salted butter gives good flavor; unsalted is fine if you prefer. Use at room temperature.
- Egg whites – Using only egg whites yields a tender white cake. Save the yolks for another use.
- Vanilla extract – Use a quality vanilla for best results.
- Milk – Whole or 2% milk, at room temperature.
- Sour cream – Full-fat sour cream or plain Greek yogurt, at room temperature, adds moisture and tang.
- Sprinkles – Use sturdy jimmies or non-melting sprinkles to preserve color in the batter and on top.
- Cream cheese – Full-fat block cream cheese, softened, for the frosting.

How to make homemade Funfetti cupcakes
Step 1: Prep. Preheat the oven to 350°F (176°C). Spray a muffin pan with nonstick spray and line with paper or silicone liners. Nonstick spray prevents sprinkles from sticking to exposed parts of the pan as the cupcakes rise.
Step 2: Make the batter. Whisk dry ingredients together in a medium bowl. In a large bowl, cream softened butter with sugar until light and fluffy. Add egg whites and beat until airy, then add vanilla and sour cream and mix just until combined. Some small lumps are fine.

Fold in the dry ingredients on low speed until just combined, scraping the bowl to incorporate any dry pockets. Add the milk and mix gently until blended. Stir in 3/4 cup of sprinkles, taking care not to overmix so they don’t bleed color.

Step 3: Bake. Fill liners about two-thirds full and bake for 18–21 minutes, or until a toothpick inserted in the center comes out clean or with dry crumbs. Remove from oven, pop cupcakes out of the pan with a butter knife if needed, and cool completely on a wire rack before frosting.


Step 4: Make the frosting. For a smooth, balanced buttercream, beat softened butter until creamy, then gradually add powdered sugar. Add a tablespoon of milk if needed for consistency, then beat in vanilla, a pinch of salt, and finally the softened cream cheese. The small amount of cream cheese cuts sweetness and makes the frosting extra creamy.

Step 5: Frost and decorate. Pipe or spread frosting onto cooled cupcakes using a piping bag, offset spatula, or butter knife. If using a piping bag, place the tip inside the bag and use a glass to hold the top while filling to keep things tidy. Twist the top of the bag to secure frosting before piping. Finish each cupcake with additional sprinkles.


Serving and storing:
Serve cupcakes soon after frosting for the best texture. Store frosted cupcakes in an airtight container in the refrigerator for up to one week. Remove them from the fridge for several minutes before serving to soften the frosting.
Expert baking tips:
- Use an oven thermometer to verify your oven’s actual temperature—accurate heat is important for consistent results.
- Weigh your flour if possible. A kitchen scale ensures consistent measurements; spoon-and-level is the preferred cup method.
- Don’t overmix once you add dry ingredients—mix just until combined to keep cupcakes tender.
- Don’t overfill pans—fill liners two-thirds full so cupcakes rise without spilling over.
- Make ahead—cupcakes can be baked a day ahead and stored at room temperature in an airtight container; frost the day you serve. Frosting can be made a day ahead and chilled; bring it to room temperature before using.
