Ingredients You’ll Need

2 cups all-purpose flour: This is the base, helping to create that lovely, tender cake. For a gluten-free option, you can use a gluten-free all-purpose blend.
2 teaspoons baking powder: Provides the lift needed for a fluffy cake. Make sure it’s fresh for the best results!
¾ teaspoon salt: Enhances flavor and balances the sweetness.
1 cup unsalted butter, melted: Essential for richness and moisture. If you prefer, coconut oil can be substituted for a dairy-free version.
1 ½ cups granulated sugar: Sweetens the cake and contributes to its texture.
4 large eggs: Helps bind ingredients and adds moisture; room temperature eggs incorporate better.
1 teaspoon vanilla extract: Adds depth of flavor; opt for pure vanilla for the best taste.
1 cup buttermilk: Keeps the cake moist while adding a subtle tang. You can substitute with regular milk plus a tablespoon of vinegar or lemon juice.
1 cup rainbow sprinkles: The star of the show! Use jimmies, as nonpareils can bleed into the batter.
1 cup unsalted butter, softened: This will be used for the frosting, providing a creamy texture. Ensure it’s at room temperature for easy blending.
4 cups powdered sugar: The sweet component of the frosting; sifted for smoothness.
1 teaspoon vanilla extract: Enhances the frosting flavor; just like before, use pure for better results.
½ teaspoon salt: Helps balance the sweetness of the frosting.
2-5 tablespoons heavy whipping cream: Needed to achieve the perfect frosting consistency; adjust based on your desired thickness.
½ cup sprinkles (plus more for topping): Adds that final festive touch to your cake!

How to Make Homemade Funfetti Cake

Preheat the Oven: Set your oven to 350°F. Prepare a 9×13-inch baking pan by greasing and dusting it with flour to prevent sticking.
Whisk the Dry Ingredients: In a medium bowl, combine 2 cups all-purpose flour, 2 teaspoons baking powder, and ¾ teaspoon salt. Set aside your dry mix.
Cream the Butter and Sugar: In a large bowl, beat together 1 cup melted unsalted butter and 1 ½ cups granulated sugar on medium speed until the mixture is smooth and well combined.
Add Eggs and Vanilla: Incorporate the 4 large eggs, one at a time, mixing well after each addition. Stir in 1 teaspoon of vanilla extract.
Combine Wet and Dry Ingredients: Gradually mix in the buttermilk (1 cup) along with the flour mixture, alternating between the two. Start and end with the buttermilk, mixing just until combined, and be sure to scrape the bowl as you go.
Stir in the Sprinkles: Gently fold in 1 cup of rainbow sprinkles to keep them vibrant and whole.
Bake the Cake: Pour the batter into your prepared baking pan and spread it evenly. Bake for 30-40 minutes, or until a toothpick inserted in the center comes out clean.
Cool Completely: Allow the cake to cool in the pan before transferring it to a wire rack to cool completely.
Prepare the Frosting: In a large bowl, beat 1 cup softened unsalted butter until creamy. Gradually add in 4 cups of sifted powdered sugar, one cup at a time, until you achieve a crumbly mixture. Mix in 1 teaspoon vanilla extract and ½ teaspoon salt. Add 2 tablespoons of heavy cream and mix until smooth, adjusting consistency with more cream as needed. Stir in ½ cup more sprinkles for added fun!
Frost the Cake: Spread the frosting generously over the cooled cake using an offset spatula. Top with additional sprinkles.
Serve & Enjoy: Your Homemade Funfetti Cake is ready to bring smiles!

Storing & Reheating

Store your Funfetti Cake tightly covered at room temperature for up to two days. For longer freshness, keep it in the refrigerator for up to a week in an airtight container. If you wish to freeze it, wrap slices or the whole cake in plastic wrap and aluminum foil, where it will stay fresh for up to three months. To enjoy, simply thaw at room temperature for about an hour or pop it in the microwave for a quick reheat (about 15-20 seconds) if you’re craving a warm slice. Just be aware that the texture might change slightly in freezing, so consider refreshing it with a little extra frosting!

Chef’s Helpful Tips

Avoid overmixing the batter after adding flour to keep the cake light and fluffy.
Ensure your butter is at the proper temperature; room temperature causes better mixing for the frosting.
If your cake rises unevenly, a gentle tap on the counter before baking can help it settle.
Experiment with different flavored extracts, like almond, for a fun twist on the frosting.
You can reserve a bit of the sprinkles to add on top of the frosting right before serving for extra color!

There’s nothing like the joy of a Homemade Funfetti Cake, both in its cheerful look and delightful taste. Besides being a crowd favorite, it’s incredibly versatile. Bake it for birthdays, celebrations, or simply when you want a treat that feels like a hug in cake form. I can’t wait to hear how yours turns out!

Recipe FAQs

Can I use cake flour instead of all-purpose flour?

Absolutely! Cake flour will give your Funfetti Cake a lighter, softer texture. Just remember to adjust the measurements, using about 1 cup and 2 tablespoons of cake flour to equate to the 2 cups of all-purpose flour.

Can I make this cake a day ahead of time?

Yes, you can bake the cake a day in advance. Allow it to cool completely, then wrap it tightly in plastic wrap and store it in the refrigerator. Just frost it on the day you plan to serve it for the best flavor and freshness.

What can I use if I don’t have buttermilk?

If you don’t have buttermilk, you can create a quick substitute by adding 1 tablespoon of vinegar or lemon juice to your measuring cup, then filling it up to the 1 cup line with regular milk. Let it sit for about 5 minutes before using.

How do I prevent my sprinkles from bleeding in the batter?

To prevent bleeding, use jimmies instead of nonpareils. Adding them at the end of the mixing process also helps keep their color intact. Enjoy the vibrant pops of color throughout your cake!
