Strawberry Funfetti Cake With Buttercream

The kitchen counter was covered in a confetti of rainbow sprinkles, and honestly, that's half the reason I started baking this cake in the first place. My niece had been begging for something colorful and strawberry-filled for her birthday, and I wanted to make something that felt like a celebration before anyone even took a bite. When the cakes came out of the oven, the scent of butter and vanilla mingled with fresh strawberries, and I knew we were in for something special.

I made this for a small gathering last spring, and my friend Sarah actually gasped when she saw the layers sliced open. The little flecks of real strawberry and pockets of sprinkles made it look so much more special than a typical box mix cake. We ate it on the back porch while the kids ran around with icing on their faces, and honestly, that's exactly the kind of memory food should create.

Ingredients

• All-purpose flour: The backbone of any good cake, providing structure while staying tender
• Baking powder: This is what gives your cake that beautiful rise, so make sure it's fresh
• Salt: Just a pinch balances all the sweetness and makes the strawberry flavor pop
• Unsalted butter: Room temperature butter is non-negotiable here—it creates that tender, velvety crumb
• Granulated sugar: Sweetens and tenderizes, creaming with the butter to create air pockets
• Large eggs: Must be at room temperature or they'll seize up your butter mixture
• Whole milk: Adds moisture and richness, also bring this to room temperature
• Fresh strawberries: Finely chopped so they distribute evenly without making the cake soggy
• Vanilla extract: Pure vanilla makes everything taste better and more comforting
• Rainbow sprinkles: Use jimmies-style sprinkles, not nonpareils, or they'll bleed into your batter
• Butter for frosting: Again, room temperature is crucial for silky smooth buttercream
• Powdered sugar: Sift it first or you'll spend twenty minutes fishing lumps out of your frosting
• Strawberry puree: Blend fresh strawberries and strain out the seeds for that gorgeous pink color and real fruit flavor

Instructions

Get your oven and pans ready:

Preheat your oven to 350°F and grease two 8-inch round pans, lining the bottoms with parchment paper so nothing sticks.

Whisk the dry ingredients together:

In a medium bowl, combine your flour, baking powder, and salt so everything is evenly distributed.

Cream the butter and sugar:

Beat butter and sugar on medium-high speed for 3 to 4 minutes until it's pale and fluffy, creating the foundation for a tender cake.

Add the eggs and vanilla:

Add eggs one at a time, beating well after each one, then stir in the vanilla until everything is smooth and glossy.

Combine wet and dry ingredients:

With the mixer on low, add flour mixture in three parts, alternating with milk, starting and ending with flour and mixing only until combined.

Fold in the fun stuff:

Gently fold in the chopped strawberries first, then the sprinkles, being careful not to overmix or the colors will bleed everywhere.

Bake until perfectly done:

Divide batter between your prepared pans, smooth the tops, and bake for 28 to 32 minutes until a toothpick comes out clean.

Let them cool completely:

Wait 10 minutes before turning cakes out onto wire racks, because warm cake will melt your frosting into a sad, slidey mess.

Make the strawberry buttercream:

Beat butter until creamy, then gradually add powdered sugar before mixing in the strawberry puree and vanilla until silky smooth.

Frost and celebrate:

Spread frosting between the layers and all over the outside, then add extra sprinkles on top because more is always more.

This cake has become my go-to for celebrations because it strikes that perfect balance between whimsical and genuinely delicious. Last time I made it, my husband took one bite and said this was the kind of cake that makes you feel like a kid again, which might be the highest compliment I've ever received.

Getting The Right Sprinkle Consistency

Not all sprinkles are created equal, and I learned this the hard way after one too many cakes with streaky, bleeding batter. The jimmies-style sprinkles hold their color beautifully during baking, while those tiny ball sprinkles will dissolve and leave you with odd little dots throughout your cake.

Working With Fresh Strawberries

Fresh strawberries add moisture, so chop them finely and pat them dry with paper towels before folding them in. I've also discovered that tossing the chopped berries in a tablespoon of flour helps keep them from sinking to the bottom of the pan while baking.

Making This Ahead Of Time

You can bake the cake layers up to a day ahead and wrap them tightly in plastic wrap at room temperature. The buttercream actually develops deeper flavor if it sits overnight in the refrigerator—just let it come to room temperature and give it a quick whip before frosting.

• Make the strawberry puree ahead and store it in the fridge
• Cupcake version bakes in just 18 to 22 minutes
• This cake stays surprisingly moist for two days if stored properly

There's something deeply satisfying about cutting into this cake and seeing those little flecks of strawberry and rainbow confetti smiling back at you. Hope it brings as much joy to your kitchen as it has to mine.

Recipe FAQs

→ Can I use frozen strawberries instead of fresh?

Yes, frozen strawberries work well. Thaw them completely and drain excess liquid before chopping for the cake batter or pureeing for the buttercream. This prevents the batter from becoming too wet and ensures proper texture.

→ How should I store this cake?

Keep the cake in an airtight container at room temperature for up to one day. For longer storage (up to 4 days), refrigerate it. Bring to room temperature before serving for the best texture and flavor.

→ Can I make this as cupcakes?

Absolutely. Fill cupcake liners about two-thirds full and bake for 18–22 minutes at 350°F. You'll get approximately 24 cupcakes. Frost with the same strawberry buttercream once completely cooled.

→ Why do my sprinkles bleed into the batter?

Over-mixing causes colors to bleed. Gently fold sprinkles in by hand just until distributed. Using jimmies-style sprinkles rather than nonpareils also helps minimize bleeding since they hold their color better during baking.

→ How can I intensify the strawberry flavor?

Add natural strawberry extract to either the cake batter, buttercream, or both. You can also reduce the strawberry puree slightly on the stovetop before adding it to the frosting for a more concentrated strawberry taste.
