Ingredients You’ll Need

2 cups all-purpose flour: This provides the structure for our cake. Make sure it’s sifted for a lighter texture.
2 teaspoons baking powder: Essential for that delightful lift. Double-check the expiration date for best results!
¾ teaspoon salt: Enhances all the flavors in your cake.
1 cup unsalted butter, melted: Adds rich flavor and moisture. Use high-quality butter for the best taste.
1 ½ cups granulated sugar: Sweetness comes from granulated sugar, which also contributes to a tender crumb.
4 large eggs: Room temperature eggs whip into the batter more easily and help create that wonderful rise.
1 teaspoon vanilla extract: Pure vanilla extract gives depth of flavor. Avoid artificial vanilla for the best results.
1 cup buttermilk: This adds moisture and a slight tang. If you don’t have buttermilk, you can make a substitute using milk combined with vinegar or lemon juice.
1 cup rainbow sprinkles: The heart of the funfetti cake. Use high-quality, non-pareils (small round sprinkles) to prevent bleeding into the cake.
1 cup unsalted butter, softened (for frosting): Softened butter blends easily to create a creamy frosting.
4 cups powdered sugar: This gives our frosting its sweetness and smooth texture.
1 teaspoon vanilla extract (for frosting): Adds flavor that complements the sweetness of the frosting.
½ teaspoon salt: Balances sweetness in the frosting, making it more delicious.
2-5 tablespoons heavy whipping cream: Used to adjust frosting consistency—start with less and add more as needed.
½ cup sprinkles plus more for topping: Additional sprinkles for that extra festive touch on top of the frosted cake!

How to Make Homemade Funfetti Cake

Preheat the Oven: Begin by preheating your oven to 350°F (175°C). Greasing and flouring a 9×13-inch baking pan helps prevent sticking.
Mix Dry Ingredients: In a medium bowl, whisk together 2 cups of all-purpose flour, 2 teaspoons baking powder, and ¾ teaspoon salt. This is your dry mix; set it aside for now.
Cream Butter and Sugar: In a large bowl, use a hand or stand mixer to beat together 1 cup of melted unsalted butter and 1 ½ cups granulated sugar on medium speed until smooth and creamy.
Incorporate Eggs and Vanilla: Add in the 4 large eggs, one at a time, ensuring each is fully incorporated before adding the next. Then blend in 1 teaspoon of vanilla extract until well mixed.
Combine Wet and Dry Ingredients: Gradually add the buttermilk (1 cup) alternately with the dry flour mixture you set aside, mixing on medium-high speed until just combined. Start and finish with the buttermilk for the perfect batter consistency, making sure to scrape the bowl down while mixing. Gently fold in the 1 cup of rainbow sprinkles.
Bake the Cake: Pour the batter into the prepared pan and smooth the top with a spatula. Bake for 30-40 minutes, or until a toothpick inserted into the center comes out clean. The cake should be lightly golden and smell heavenly.
Cool Completely: Allow the cake to cool completely in the pan on a wire rack before frosting.
Prepare the Frosting: In a mixing bowl, beat 1 cup of softened unsalted butter until creamy. Gradually add in 4 cups of powdered sugar, one cup at a time, mixing until you achieve a crumbly mixture. Add in 1 teaspoon of vanilla extract and ½ teaspoon salt, mixing well. Pour in 2 tablespoons of heavy cream, mixing until smooth, and adjust with more cream for desired consistency. Stir in additional sprinkles for a vibrant finish.
Frost the Cake: Once the cake is completely cool, frost generously with your prepared frosting using a spatula. Top with more sprinkles for an extra burst of color! Store loosely covered at room temperature for up to 2 days.

Storing & Reheating

To store your Homemade Funfetti Cake, keep it at room temperature in a loosely covered container for up to 2 days. For longer freshness, refrigerate in an airtight container for about a week. This cake also freezes beautifully; wrap it tightly in plastic wrap and then in aluminum foil for up to 3 months. When you’re ready to enjoy, simply thaw at room temperature. While refrigerator storage is safe, remember the texture might change slightly; refreshing it with a bit of whipped cream can help!

Chef’s Helpful Tips

Avoid overmixing the batter to keep the cake light and fluffy.
Ensure your eggs and buttermilk are at room temperature; this helps with incorporation.
If you want a more intense flavor, consider adding a bit more vanilla or even a splash of almond extract.
For a moist cake, check for doneness at 30 minutes; every oven is unique!
If you love a thicker frosting, feel free to increase the powdered sugar by ½ cup.

Homemade Funfetti Cake is not just a treat; it’s a celebration in every bite! You get to embrace the joyful colors, the tantalizing sweetness, and the nostalgia of childhood birthdays while creating a delightful baked good. I encourage you to try your hand at making this cake, add your personal touch, and perhaps even incorporate your favorite mix-ins.
