    Homemade Funfetti Cake

    There is no other cake that can bring a smile to anyone’s face more than Funfetti Cake.

    In the event you’ve never had it, it’s a vanilla cake full of colorful little spots thanks to sprinkles that bake into the cake. It’s made with simple ingredients available from any grocery store.

    Our version couldn’t be easier made as a Texas sheet cake. Instead of round cake pans, this style of cake is a single layer cake baked in a rimmed baking sheet. The servings are only about an inch or so in depth but it makes plenty to feed a crowd.

    Homemade vanilla buttercream frosts the top which is covered with plenty of sprinkles too!

    This sprinkle cake is always a huge hit! I’ve been told more than once that this homemade version is the best funfetti cake!

    Recipe Ingredients + Notes

    Granulated sugar. Sweetens the cake.

    All Purpose Flour. Regular or gluten-free measure-for-measure can be used. We recommend Bob’s Red Mill gluten-free 1-to-1 baking flour for the gluten-free version. Cake flour is not needed for this confetti cake.

    Baking Soda. This helps the cake rise.

    Salt. We recommend using Kosher salt which is a less salty flavored salt.

    Unsalted butter. Some will be used melted for the cake and you’ll need room temperature butter for the frosting.

    Vanilla yogurt. Plain yogurt with 1 teaspoon vanilla extract stirred in can also be subsituted.

    Eggs. Three large eggs.

    Sprinkles. To make the cake a true funfetti the best sprinkles to use are rainbow jimmies. They hold their color and work best.

    Nonpareils tend to bleed during the baking process. More will be used on the finished cake and any type work (rainbow sprinkles are very festive).

    funfetti cake ingredients labelled

    Powdered sugar. Also called confectioners’ sugar, will be used to make the buttercream frosting.

    Vanilla extract. Used to give the frosting wonderful flavor.

    Heavy whipping cream. This is used in the frosting.

    Variations

    Frosting thickness. This recipe will provide enough for a thin layer of buttercream frosting. If a thick, fluffy layer is desired double the frosting recipe.

    Swap milk for the heavy cream. The heavy whipping cream is used for a rich flavor although regular milk can also be swapped in instead.

    Make chocolate frosting instead. Funfetti cake is traditionally made with a vanilla frosting, chocolate lovers can turn this into chocolate cake (well, chocolate frosting really)! Add 4 tablespoons of cocoa powder to the frosting during the first step.

    Make it in a 9-inch by 13-inch pan instead. If you do not have a rimmed cookie sheet or prefer a baking pan, make this in a 9-inch by 13-inch pan instead.

    The cooking time will need to be extended; check the cake at the 20 minute mark and continue cooking for 5-10 minutes at a time until a toothpick inserted into the center of the cake comes out clean.

    How to make Funfetti Cake – Step-by-Step

    Stir in the yogurt (photo 4).

    Add the eggs, one at a time and mixing between each addition (photo 5).

    Allow the cake to cool completely on a wire rack before frosting (photo 9).

    funfetti cake recipe steps 9-12

    STEP 4. Make the vanilla buttercream frosting

    In a large bowl, using an electric mixer or in the bowl of a stand mixer with the paddle attachment, mix the butter and powdered sugar together on high speed until fully combined and creamy (photos 10-11).

    Add the vanilla, salt and 6 tablespoons of heavy cream. Beat until well combined with a fluffy texture (photos 12-13).

    NOTE: If the frosting is too thick to easily spread, then add the remaining 2 tablespoons of heavy cream.

    funfetti cake recipe steps 13-16

    STEP 5. Frost the cake

    Using a scoop or a spoon, drop large mounds of icing over the top of the cake (the entire cake –photo 14).

    Use a spatula (regular or offset spatula )or knife to spread the frosting to the edges (photo 15). Top with the sprinkles topping (photo 16).

    How to Store it

    Store covered tightly with plastic wrap or in an airtight container at room temperature for 3-4 days.

    Notes

    Variations
    Funfetti cake is traditionally made with a vanilla frosting, but the frosting can be made chocolate too. Add 4 tablespoons of cocoa powder to the frosting during the first step.
    The cake can also be made in a 9-inch by 13-inch baking pan instead of a baking/cookie sheet. The cooking time will need to be extended, check the cake at the 20 minute mark and continue cooking for 5-10 minutes at a time until a toothpick inserted into the middle comes out clean.
    Frosting amount
    This will provide enough frosting for a thin layer of frosting. If a thick fluffy layer is desired, then double this frosting recipe.

      What a gorgeous looking fun cake! Perfect for a children’s birthday party. I didn’t realise that the long rainbow sprinkles worked better than hundreds and thousands… that’s where I’ve been going wrong with my previous bakes! Thanks for the awesome recipe!
