What Is a Confetti Snack Cake?
A confetti snack cake is a soft, moist vanilla cake laced with rainbow sprinkles, baked in a single pan and topped with a layer of creamy frosting. This treat is sometimes called “funfetti,” thanks to its playful appearance. Unlike layer cakes, snack cakes are easy to make and serve, making them perfect for casual gatherings or weeknight treats.
- Simple one-pan method—no special equipment needed
- Vibrant, fun sprinkle-filled batter for a burst of color in every bite
- Fluffy vanilla frosting that pairs perfectly with the tender crumb
Ingredients for Confetti Snack Cake
To make the ultimate confetti snack cake, gather these essential ingredients:
- All-purpose flour
- Granulated sugar
- Baking powder
- Kosher salt
- Unsalted butter (room temperature)
- Eggs
- Whole milk
- Pure vanilla extract
- Rainbow sprinkles (jimmies-type works best for baking)
For the frosting:
- Unsalted butter (softened)
- Powdered sugar
- Whole milk or heavy cream
- Pure vanilla extract
- A pinch of salt
- Extra sprinkles for topping
Tip: Avoid nonpareil or confetti dot sprinkles inside the batter, as they tend to bleed color and can make the cake muddy—jimmies hold up best.
Step-By-Step Instructions: How to Bake Confetti Snack Cake
- Preheat your oven to 350°F (180°C). Grease a 9×13-inch baking pan and line with parchment paper for easy removal.
- Mix the dry ingredients. In a large bowl, whisk together flour, baking powder, and salt.
- Cream butter and sugar. In a stand mixer or with a hand mixer, beat the butter and sugar on medium speed until light and fluffy—about 3 to 5 minutes.
- Add eggs and vanilla. Add eggs, one at a time, mixing well after each addition. Beat in the vanilla extract.
- Alternate mixing wet and dry ingredients. With the mixer on low speed, add the dry mixture in three parts, alternating with the milk. Begin and end with the dry ingredients.
- Stir in the sprinkles. Gently fold in the rainbow sprinkles with a spatula, taking care not to overmix.
- Bake the cake. Spread the batter into the prepared pan and smooth the top. Bake for 25–30 minutes, or until a toothpick inserted into the center comes out clean.
- Cool the cake in the pan for 15 minutes, then lift out and let it cool completely on a wire rack.
Making Buttercream Frosting
While the cake cools, prepare a luscious vanilla buttercream frosting:
- In a mixing bowl, beat the softened butter until creamy, about 2 minutes.
- Add the powdered sugar, one cup at a time, beating well and scraping down the sides as needed.
- Mix in the vanilla extract and a pinch of salt.
- Pour in milk or heavy cream a tablespoon at a time, until desired consistency is reached—smooth and spreadable, but not runny.
Pro Tip: For fluffier frosting, beat for an additional 2–3 minutes at medium-high speed after all ingredients are combined.
Assembling and Decorating the Cake
Decorating is where the fun begins! Follow these steps to achieve that signature festive look:
- Frost the cooled cake with an even layer of buttercream. Use an offset spatula for a smooth finish.
- Sprinkle liberally with extra rainbow sprinkles, gently pressing some into the frosting for better adhesion.
- For themed parties, add shaped sprinkles, edible glitter, or confetti candies on top.
- If desired, pipe extra frosting around the edges or add a message for birthdays or special occasions.

Frequently Asked Questions (FAQs)
Q: Can I use non-dairy milk or gluten-free flour?
A: Yes, you can substitute non-dairy milk or use a 1:1 gluten-free flour blend. The texture may differ slightly, but the cake will still be delicious.
Q: Why did my sprinkles sink to the bottom?
A: The batter may have been too thin, or the sprinkles were too heavy. Make sure to use lighter “jimmies” sprinkles and incorporate them gently right before baking.

A: Absolutely! Confetti snack cake holds up well when made ahead. Store it covered at room temperature or in the fridge if your kitchen is warm.

A: Use a long, sharp knife, wiping it clean between cuts. Chilling the cake briefly before slicing can help with neat edges.
Q: What kind of pan can I use if I don’t have a 9×13-inch?
A: You can use two 8-inch square or round pans, adjusting bake time as necessary—check for doneness with a toothpick.
Celebration Variations: Beyond the Basics
