Ingredients You’ll Need

2 cups all-purpose flour (248g): Essential for structure. To substitute, use cake flour for a lighter texture.
2 teaspoons baking powder: This helps the cake rise and become fluffy.
¾ teaspoon salt: Balances sweetness.
1 cup unsalted butter, melted (226g): Provides rich flavor. You could use coconut oil for a dairy-free option.
1 ½ cups granulated sugar (300g): For sweetness and moisture; brown sugar can add flavor depth.
4 large eggs: Helps with the cake’s structure and binds ingredients. Room temperature eggs work best!
1 teaspoon vanilla extract: Adds a warm, sweet flavor. Use pure vanilla for the best taste.
1 cup buttermilk (237ml): Makes the cake very moist. If unavailable, mix 1 tbsp lemon juice or vinegar into regular milk.
1 cup rainbow sprinkles (225g): For that festive funfetti look. Make sure to use nonpareils for the best integration into the batter and frosting.
1 cup softened unsalted butter (226g): For the frosting, providing a creamy texture. Room temperature butter mixes better.
4 cups powdered sugar (452g): Sweetness and structure for the frosting; sift for a smoother texture.
1 teaspoon vanilla extract: Reinforces the frosting’s flavor.
½ teaspoon salt: Enhances flavor in the frosting.
2-5 tablespoons heavy whipping cream (30-75ml): Adjust for the desired frosting consistency; milk can be a substitution.
½ cup sprinkles: A generous topping to finish off your cake, or use more for extra crunch.

How to Make Homemade Funfetti Cake

Preheat and Prep: Start by preheating your oven to 350°F. Prepare a 9×13-inch baking pan by greasing and flouring it well, ensuring your cake doesn’t stick.
Mix Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, baking powder, and salt. Set this mixture aside.
Cream Butter and Sugar: In a large bowl, use a stand mixer or hand mixer on medium speed to combine the melted butter and granulated sugar until the mixture is smooth and creamy.
Incorporate Eggs and Vanilla: Add in each egg one by one, mixing well after each addition, then stir in the vanilla extract until combined.
Combine Wet and Dry Mixtures: Add the buttermilk alternately with the flour mixture, beginning and ending with the buttermilk. Mix on medium-high speed until combined, but be careful not to overmix. Scrape down the sides of the bowl to ensure everything is incorporated. Fold in the rainbow sprinkles gently.
Bake: Pour the batter into your prepared pan. Bake for 30-40 minutes, or until the edges are lightly golden and a toothpick inserted comes out clean. Allow the cake to cool completely in the pan.
Frosting Preparation: For the frosting, beat the softened butter until smooth and creamy. Gradually add powdered sugar one cup at a time until a crumbly mixture forms. Mix in the vanilla and salt, then pour in 2 tablespoons of heavy cream. Whip until smooth, adding more cream as needed to achieve your desired consistency. Gently fold in a handful of sprinkles for added fun.
Final Touches: Once the cake is completely cool, frost it using an offset spatula. Top with additional sprinkles for that festive look! You can also store the cake loosely covered at room temperature for up to 2 days.

Storing & Reheating
To keep your Homemade Funfetti Cake fresh, store it at room temperature in an airtight container for up to 2 days. If you need to keep it longer, refrigerate it for up to a week. For freezing, wrap individual slices tightly in plastic wrap and then in aluminum foil—this will keep them fresh for up to 3 months. To reheat, place a slice in the microwave for about 10-15 seconds until just warm; it will refresh both the flavor and texture.

Chef’s Helpful Tips

Ensure your eggs and butter are at room temperature for best results. Cold ingredients can create a dense cake.
Avoid overmixing the batter after adding the flour; this can lead to a tough cake.
Use nonpareil sprinkles instead of sugar crystals for better integration into the batter and frosting.
If your cake domes while baking, you can level it off with a serrated knife once it cools.
For extra flavor, add a teaspoon of almond extract to the frosting, which pairs beautifully with vanilla.

You will absolutely adore this sweet, nostalgic treat that brings bright colors and smiles to any occasion! The blend of fluffy cake and tasty frosting is worth every moment spent in the kitchen. Don’t shy away from experimenting with different types of sprinkles or toppings that reflect your personal style.

Recipe FAQs

Can I make this cake in advance?

Yes! You can make the cake a day ahead and store it covered at room temperature. If you plan to frost it later, consider frosting just before serving to keep it looking fresh.

How can I make a smaller cake?

If you only need a small cake, this recipe can be adapted to make two 9-inch round cakes or even 24 funfetti cupcakes! Just reduce the baking time for cupcakes to about 15-18 minutes.

What if I don’t have buttermilk?

No problem! You can make a quick substitute by adding 1 tablespoon of white vinegar or lemon juice to regular milk. Let it sit for about 5 minutes before using it in your recipe.

What storage methods can I use for leftovers?

Leftover cake can be stored in an airtight container at room temperature for around 2 days, or in the refrigerator for up to one week. For long-term storage, wrap slices in plastic and foil and freeze them for up to 3 months. Enjoy your sweet adventures!
