Funfetti cake is one of those iconic recipes that makes people happy. Kids love the colors and sprinkles and adults love the trip back to memory lane when sprinkle cakes were at nearly every birthday party. For this funfetti cake recipe, I wanted to use the recipe from my Chocolate Sheet Cake which I had already modified for my Caramel Sheet Cake. It’s such an easy recipe and turns out moist and perfect every time. I love this recipe because it requires no mixer, just a whisk, and it comes together in just a few minutes. Anything that’s easy and gets me in and out of the kitchen fast is a winner in my book!

Funfetti Cake

This recipe for homemade funfetti cake makes just enough for two 9-inch layers or one sheet cake. I use my Homemade Buttercream Frosting Recipe but the cake would also be great with the Cream Cheese Frosting from my Red Velvet Cake.

What do you need for this sprinkle cake?

  • SprinklesIf you’re going to be baking with sprinkles then buy them in large quantities since it’s much less expensive than buying multiple small containers from the grocery store. And if kids are helping you, you’ll go through A LOT of sprinkles!
  • Cake pansI love these cake pans from Fat Daddio. You can pay more at a specialty cooking store, but why?
  • Cake standthis funfetti cake is so pretty, it deserves a lovely display. I adore this aqua-mint color and I’m coveting this stand myself!

How to Make Funfetti Cake

Step 1. Start by generously buttering and flouring two 9-inch cake pans.

Step 2. Mix the sprinkles with a little flour to coat them and set them aside. Then sift the remaining flour and salt into a large bowl. Add the sugar and whisk it all together until well blended. Step 3. This is the part that give this funfetti cake its special moist texture! Combine all of the butter and water in a saucepan and bring to a boil. Then pour the melted butter over the flour mixture and just whisk until it’s all blended and looking like batter.

Pro Tip: You can certainly use a hand mixer here, but usually the boiling butter/water mixture is enough to make everything mix up smoothly in just a jiffy.

Step 4. Measure the buttermilk in a measuring cup, then whisk the eggs, soda, and vanilla into the measuring cup. Whisk this into the batter and stir until blended and smooth, then gently stir in the flour-coated sprinkles. Step 5. Pour the batter into the prepared pans and bake for 20-25 minutes, checking the cake after about 15 minutes. The funfetti cake is done when your tester comes out clean but be careful not to overcook. Step 6. Remove pans from oven and allow the cake to cool on a rack for 15 minutes. Then turn the layers onto parchment covered racks and allow them to cool completely, 30 minutes to an hour. Step 7. Frost the sprinkle cake with Classic Buttercream Frosting or Cream Cheese Frosting.

Pro Tip: You could add a little food coloring to make the frosting a fun color like pink, green, or blue!

Tips – How to Put Sprinkles on the Side of a Cake

Once your funfetti cake has frosting on it, just lightly press some sprinkles onto the frosting. Kids love to do this! It doesn’t have to be perfect, just fun and colorful. Here’s a fun guide to a Sprinkles Birthday Party where you could showcase this fun sprinkle cake!
