This is a funfetti vanilla cake layered with cream cheese frosting and crunchy cake crumbs, baked in a single 9-inch springform pan and finished with a semi-naked look that skips the fussy full-coverage frost job. It takes about 1 hour 40 minutes start to finish and serves 12. If you want a homemade birthday cake that actually holds its shape when sliced and travels well in a box, this is a reliable one to have in your rotation.
Smart swaps
- Clear vanilla extract: This is worth tracking down — it gives the frosting and cake that bright, sweet vanilla flavor you recognize from grocery-store birthday cakes. Pure vanilla works but produces a slightly more complex, less “classic birthday” taste and tints the frosting ivory.
- Buttermilk: If you don’t have it, stir 1 tablespoon of white vinegar or lemon juice into ¾ cup whole milk and let it sit 5 minutes before using.
- Confetti sprinkles vs. nonpareils: Stick with confetti (disc-shaped) sprinkles in the batter. Nonpareils bleed color into the crumb and turn the inside of the cake grey-purple.
What makes this version work
Two things matter most here. First, the alternating flour-buttermilk addition — starting and ending with flour — keeps the batter from breaking and gives you a fine, even crumb that holds together cleanly when you slice through the layers. Second, the cream cheese frosting needs both the butter and cream cheese fully softened before you start. Cold cream cheese leaves lumps that no amount of extra mixing will smooth out, and over-mixing a warm frosting turns it loose and greasy. Get both to true room temperature and the frosting will come together in under three minutes and stay firm enough to pipe or spread without sliding.
Mistakes to avoid
- Cutting into a warm cake: The layers compress and tear if the cake isn’t completely cool before you level and frost it. Give it at least an hour at room temperature, or 20 minutes in the fridge after it reaches room temp.
- Skipping the parchment on the pan bottom: The sugar in this batter sticks. Even a well-greased springform pan can leave the bottom layer behind when you release the sides — parchment prevents that entirely.
- Over-folding the sprinkles: Fold them in with a spatula using as few strokes as possible. Aggressive mixing crushes the sprinkles and smears color through the batter.
- Adding too much milk to the frosting: The recipe calls for ¼ cup whole milk — add it gradually, a tablespoon at a time, until you hit a spreadable consistency. The exact amount can vary depending on your cream cheese brand. Skip the garnish of extra sprinkles on top if you’re boxing this up — they slide off during transport and add nothing once the cake is covered.
- Storing unfrosted cake layers uncovered: If you bake the cake ahead, wrap the cooled layer tightly in plastic wrap. Even a few hours uncovered dries out the edges and makes the crumb crumbly rather than tender.

Equipment
- Stand Mixer
- Oven
- 9-inch Springform Pan
- Parchment Paper
- Mixing Bowls
- Spatula
- Spoon
Ingredients
Cake and Crumb
- 1 and ¼ cups all-purpose flour for the cake
- 1 cup granulated sugar for the cake
- ¼ cup light brown sugar packed for the cake
- ¾ cup buttermilk room temperature
- ½ cup unsalted butter softened for the cake
- 3 large eggs room temperature
- ¼ cup vegetable oil for the crumb
- 1 tablespoon clear vanilla extract for the cake
- ⅔ cup Confetti sprinkles for cake batter
Frosting
- 2 cups confectioners' sugar sifted
- 8 oz cream cheese softened
- ½ cup unsalted butter softened
- 2 teaspoons clear vanilla extract
- ¼ cup whole milk room temperature
Instructions
- Preheat the oven to 350°F (175°C). Prepare a 9-inch springform pan by lining it with parchment paper.
- In a stand mixer, cream together the butter, granulated sugar, and brown sugar on medium speed until light and fluffy, about 3-4 minutes.
- Add in the eggs, one at a time, beating well after each. Add clear vanilla extract and mix until combined.
- Reduce mixer speed to low and alternate adding the flour and buttermilk, starting and ending with the flour. Mix until just combined.
- Gently fold in the confetti sprinkles with a spatula.
- Pour the batter into the prepared pan and bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
- While the cake bakes, prepare the frosting. In a clean bowl, whip together cream cheese, butter, and confectioners' sugar until smooth and fluffy.
- Beat in the vanilla extract and milk until the frosting is spreadable and creamy.
- Once the cake is cool, level the top with a serrated knife if necessary. Frost the cake and adorn with additional sprinkles for a festive finish.
Notes
Tammy’s Tips
- For a richer taste, substitute half of the cream cheese in the frosting with mascarpone.
- If you want to make the cake a day ahead, wrap the layers tightly in plastic wrap and refrigerate. Frost when ready to serve.
- For a nut-free version, ensure your sprinkles are free from any nut cross-contamination.

Common questions
Can I bake the cake a day ahead?
Yes — baking a day ahead actually makes assembly easier. Wrap the fully cooled, unfrosted cake layer tightly in plastic wrap and keep it at room temperature overnight, then level, frost, and finish it the next day.
How do I store the finished cake, and how long does it keep?
Store the frosted cake in an airtight container or cake box in the refrigerator for up to 4 days. The cream cheese frosting requires refrigeration, but let slices sit at room temperature for 20–30 minutes before serving so the cake crumb softens back up.
Can I freeze this cake?
Freeze the unfrosted cake layer, not the finished frosted cake — cream cheese frosting doesn’t thaw well and tends to weep. Wrap the cooled layer in plastic wrap, then foil, and freeze for up to 6 weeks; thaw overnight in the fridge still wrapped.
Will this cake survive being packaged and gifted?
It holds up well in a standard cake box for several hours at room temperature, or longer if you keep it cold. The semi-naked sides mean the frosting isn’t thick enough to smear against the box walls, and the crumb structure is sturdy enough that slices don’t collapse — just make sure the frosting is fully set and chilled before you close the box.
