Ingredients You’ll Need

2 cups (248g) all-purpose flour: This forms the base of our cake. For a gluten-free alternative, you can use a 1:1 gluten-free flour blend.
2 teaspoons baking powder: This will give the cake a lovely rise and light texture.
¾ teaspoon salt: Balances the sweetness and enhances flavors.

1 ½ cups (300g) granulated sugar: Sweetens the cake beautifully, contributing to its moistness.
4 large eggs: Essential for structure and richness. Use room-temperature eggs for best results.
1 teaspoon vanilla extract: Enhances the cake’s flavor; opt for pure vanilla extract for a more indulgent taste.
1 cup (237ml) buttermilk: Adds moisture and creates a tender crumb. If you don’t have buttermilk, mix 1 cup of milk with 1 tablespoon of vinegar and let it sit for 5 minutes.
1 cup (225g) rainbow sprinkles: The fun element! Be sure to use high-quality sprinkles so they hold their color during baking.
1 cup (226g) unsalted butter, softened: For the frosting, providing a creamy and rich texture.
4 cups (452g) powdered sugar: For sweetness and to achieve a smooth frosting consistency.
1 teaspoon (15 ml) vanilla extract: Adds an extra layer of flavor.
½ teaspoon salt: Balances the sweetness of the frosting.
2-5 tablespoons (30-75ml) heavy whipping cream: To reach your desired frosting consistency; adjustable based on your preference.
½ cup (112g) sprinkles plus more for topping: A perfect way to finish your cake — more color and fun on top!

How to Make Homemade Funfetti Cake

Prep Your Oven: Preheat your oven to 350°F. Grease and flour a 9×13-inch baking pan to ensure nothing sticks when it’s beautifully baked.
Mix Dry Ingredients: In a medium bowl, whisk together 2 cups all-purpose flour, 2 teaspoons baking powder, and ¾ teaspoon salt. Set this mixture aside as we prepare the wet ingredients.
Combine Wet Ingredients: In a large bowl, use a hand or stand mixer to beat 1 cup melted unsalted butter and 1 ½ cups granulated sugar on medium speed until smooth. Then, add in the 4 large eggs, one at a time, mixing well after each addition. Follow up by mixing in 1 teaspoon vanilla extract.
Blend Together: Add the prepared buttermilk alternately with the dry flour mixture, mixing on medium-high speed between each addition, beginning and ending with the buttermilk. Make sure you scrape down the sides of the bowl to combine everything well. Gently stir in 1 cup of rainbow sprinkles until evenly distributed.
Bake the Cake: Pour the batter into your prepared baking pan and spread it out evenly. Bake for 30-40 minutes, or until edges are lightly golden and a toothpick comes out clean when inserted in the center. Allow the cake to cool completely before frosting.
Make the Frosting: In a large bowl, beat 1 cup softened unsalted butter with a mixer until creamy. Gradually add in 4 cups powdered sugar, one cup at a time, until the mixture appears crumbly. Add in 1 teaspoon vanilla extract, and ½ teaspoon salt, and mix until smooth. Then, add 2 tablespoons of heavy whipping cream and mix until it reaches a spreadable consistency. You can add more cream if necessary. Finally, stir in an additional ½ cup of sprinkles for that extra touch.
Frost the Cake: Once the cake is cooled, generously spread the frosting on top using an offset spatula for a neat finish. Top it off with more sprinkles for that festive look!
Storing and Enjoying: Store uneaten cake loosely covered at room temperature for up to 2 days. Also, this batter works well as 24 cupcakes, two 9-inch rounds, or three 8-inch rounds—perfect for any baking endeavor you have in mind!

Storing & Reheating

To store your Homemade Funfetti Cake, simply cover it loosely with foil or keep it in an airtight container at room temperature for up to 2 days. If you wish to keep it longer, refrigerate it for up to a week in a covered container. You can also freeze the cake for up to 3 months; just ensure it’s securely wrapped to prevent freezer burn. When ready to enjoy, let the cake thaw at room temperature, or warm it gently in the microwave for about 10-15 seconds — it will be just as delightful!

Chef’s Helpful Tips

Avoid overmixing the batter once you add the flour to keep the cake light and fluffy.
Check your baking powder for freshness before using; expired baking powder can lead to a dense cake.
If your butter is too warm when mixing the frosting, the texture may become too soft. Ensure it’s just softened.
For a flavor twist, try lemon or almond extract to replace the vanilla occasionally.
Make the frosting ahead of time and store it in the refrigerator; just remember to let it come to room temperature before using.

Every slice of this cake is an invitation to celebrate life’s sweet moments. Homemade Funfetti Cake is more than just a dessert; it’s a manageable way to sprinkle joy into everyday life. Explore with different variations and flavors, and don’t hesitate to try combining it with various frostings or fillings. Happy baking!

Recipe FAQs

Can I make this cake ahead of time?

Absolutely! You can bake the cake a day in advance and frost it just before serving. It also works wonderfully if frozen without frosting; just thaw and frost before serving.

Can I use a different type of sprinkles?

Yes! While rainbow sprinkles are classic, feel free to experiment with themed sprinkles to match your occasion. Just make sure they’re the nonpareils or jimmies, as other types may bleed color into the batter.

Can I replace buttermilk with milk?

If you don’t have buttermilk, you can create a substitute by mixing 1 cup of milk with 1 tablespoon of vinegar. Let it sit for about 5 minutes to curdle before adding it to the batter.

How do I prevent my cake from sinking in the middle?

Ensure you’ve properly measured your flour and didn’t overmix your batter. Also, check your oven temperature with an oven thermometer to confirm it’s accurate, as ovens can vary widely in actual temperature.
