The secret to this cake's incredible texture lies in the combination of whole milk and sour cream, which create a tender, moist crumb that stays fresh for days. Unlike box mix funfetti cakes, this homemade version uses real butter and pure vanilla extract for authentic flavor that shines through. The pastel buttercream is silky smooth and not overly sweet, providing the perfect canvas for creative decorating—whether you prefer elegant rosettes, casual dollops, or marbled rainbow swirls.

Instructions

Step 1: Prepare the pans

Preheat oven to 350°F (175°C). Grease and line two 9-inch (23 cm) round cake pans with parchment paper.

Step 2: Mix dry ingredients

In a medium bowl, whisk together flour, baking powder, baking soda, and salt.

Step 3: Cream butter and sugar

In a large bowl, beat the butter and sugar together until light and fluffy (about 3 minutes).

Step 4: Add eggs and vanilla

Add eggs one at a time, beating well after each addition. Mix in vanilla extract.

Step 5: Combine wet ingredients

In a separate bowl, whisk milk and sour cream until combined.

Step 6: Alternate mixing

Add the flour mixture to the butter mixture in three parts, alternating with the milk mixture, beginning and ending with flour. Mix just until combined.

Step 7: Fold in sprinkles

Gently fold in the rainbow sprinkles with a spatula.

Step 8: Fill pans

Divide batter evenly between the prepared pans. Smooth tops.

Step 9: Bake

Bake for 28–32 minutes, or until a toothpick inserted into the center comes out clean.

Step 10: Cool cakes

Cool cakes in pans for 10 minutes, then turn onto a wire rack to cool completely.

Step 11: Make buttercream base

Beat butter until smooth and creamy (about 2 minutes).

Step 12: Add sugar

Gradually add powdered sugar, mixing on low until incorporated.

Step 13: Finish buttercream

Add milk, vanilla, and salt. Beat on high until fluffy (2–3 minutes).

Step 14: Color the buttercream

Divide buttercream into 4 bowls. Tint each with a different pastel color using food gel.

Step 15: Decorate

Dollop or pipe colored buttercream onto cooled cake layers as desired. Swirl colors together for a marbled pastel effect.

Zusatztipps für die Zubereitung

Room temperature ingredients are crucial for this recipe—cold eggs or butter can cause the batter to curdle or mix unevenly. Set everything out about an hour before baking. When folding in sprinkles, use jimmies rather than nonpareils, as the latter tend to bleed color into the batter. If your buttercream becomes too soft while coloring, refrigerate for 10–15 minutes before decorating. For the cleanest cake layers, use a serrated knife to level the tops before stacking, and apply a thin crumb coat of frosting before the final decoration.

Varianten und Anpassungen

Transform this recipe into 24 cupcakes by adjusting the baking time to 22–24 minutes—perfect for individual party servings. Substitute Greek yogurt for sour cream if needed for a slightly tangier flavor profile. For a different seasonal twist, swap the pastel colors for bold primary hues or monochromatic shades. You can also add 1/2 teaspoon of almond extract to the buttercream for a subtle nutty note that complements the vanilla beautifully. For chocolate lovers, replace 1/2 cup of flour with cocoa powder to create a funfetti chocolate cake base.

Serviervorschläge

This cheerful cake pairs beautifully with a glass of sparkling Moscato or fresh lemonade for a refreshing contrast to the rich buttercream. Serve at room temperature for the best flavor and texture—the buttercream softens slightly and the cake's vanilla notes become more pronounced. Garnish individual slices with extra sprinkles or fresh edible flowers like pansies or violets for an elegant spring presentation. For children's parties, serve alongside vanilla ice cream or fresh strawberries. The cake stores well covered at room temperature for 2 days or refrigerated for up to 5 days.
