1 teaspoon vanilla extract: Adds a warm, aromatic flavor. Use pure vanilla for the best taste.
1 cup (237ml) buttermilk: Keeps the cake moist and tender. If unavailable, you can make a substitute using milk and vinegar or lemon juice.

1 cup (226g) unsalted butter, softened: Used for the frosting, provides a creamy texture.
4 cups (452g) powdered sugar (confectioners’ sugar): Sweetens the frosting and gives it that fluffy consistency.
1 teaspoon (15 ml) vanilla extract: Enhances the flavor of the frosting.

How to Make Homemade Funfetti Cake

Preheat the Oven: Set your oven to 350°F (175°C) and grease and flour a 9×13-inch baking pan for easy release.
Combine Dry Ingredients: In a medium bowl, whisk together 2 cups all-purpose flour, 2 teaspoons baking powder, and ¾ teaspoon salt. Set aside while you work on the wet ingredients.
Mix the Butter and Sugar: In a large bowl, blend 1 cup melted unsalted butter and 1 ½ cups granulated sugar on medium speed until smooth and creamy.
Incorporate Eggs and Vanilla: Add the 4 large eggs one at a time, mixing well after each addition, then stir in 1 teaspoon vanilla extract until fully combined.
Combine Wet and Dry Mixtures: Pour in 1 cup buttermilk alternately with the dry mixture, mixing on medium-high speed between each addition. Start and end with the buttermilk for best results. Scrape down the sides of the bowl, and gently fold in 1 cup rainbow sprinkles.
Bake the Cake: Transfer the batter into the prepared pan. Bake for 30-40 minutes, until the edges are golden and a toothpick inserted into the center comes out clean. Allow it to cool completely before frosting.
Prepare the Frosting: Beat 1 cup softened unsalted butter until creamy. Gradually mix in the 4 cups powdered sugar one cup at a time until crumbly. Add in 1 teaspoon vanilla extract and ½ teaspoon salt, then mix in 2 tablespoons heavy whipping cream. Adjust the texture by adding more cream until you achieve a smooth consistency. Finally, fold in ½ cup of sprinkles.
Frost and Serve: Spread the frosting evenly over the cooled cake with an offset spatula. Top with additional sprinkles if desired. Store loosely covered for up to 2 days.
Alternate Serving Options: This batter also works well for 24 cupcakes, two 9-inch round layers, or three 8-inch round cakes.

Storing & Reheating

To store leftovers, keep the funfetti cake loosely covered at room temperature for up to 2 days. For longer freshness, refrigerate it in an airtight container for up to a week. If you want to freeze it, wrap slices in plastic wrap and place them in a freezer-friendly bag; it will keep well for up to three months. When ready to enjoy, thaw at room temperature or warm in the microwave for about 10-15 seconds. It’s best when the frosting is fresh, so you may wish to add a little extra on top afterward.

Chef’s Helpful Tips

Avoid overmixing once you combine the wet and dry ingredients; this helps maintain a light, airy cake.
Ensure your butter for frosting is softened but not melted for the best consistency.
If your cake domed while baking, trim the top with a serrated knife for even frosting.
Experiment with different types of sprinkles for unique effects; nonpareils work beautifully in the batter.
For a richer flavor, consider adding almond extract to the cake batter.

Homemade Funfetti Cake is a sweet treat that combines joy, color, and flavor in each slice. Not only does it shine visually, but it appeals to both kids and adults alike, making it a flexible dessert for almost any occasion. Whether you decide to make it for a party or to satisfy a craving, each bite is sure to bring a smile. Don’t hesitate to get creative with flavors, fillings, and toppings, as this cake is a perfect canvas for your imagination!

Recipe FAQs

Can I make this recipe gluten-free?

Absolutely! You can substitute the all-purpose flour with a 1:1 gluten-free blend. Just make sure the blend contains xanthan gum for the right texture.

How can I make this cake dairy-free?

To make a dairy-free version, use vegan butter and a dairy-free milk alternative like almond milk mixed with vinegar instead of buttermilk.

What can I do if my cake isn’t rising properly?

If your cake didn’t rise, double-check that your baking powder isn’t expired. Also, make sure to mix thoroughly but avoid overmixing the batter.

Can I use a different type of frosting?

Sure! Cream cheese frosting or a chocolate ganache can be delightful alternatives that pair beautifully with the sweetness of the cake.
