Strawberry Funfetti Cake with Buttercream

The kitchen smelled like berries and butter when my niece bounded in, spotted the rainbow sprinkle jar on the counter, and whispered like we were plotting something delicious. We made this cake together for her eighth birthday, and I have never seen anyone more solemn about carefully folding sprinkles into batter than she was, treating each color confetti piece like it held the secret to happiness itself.

That birthday party taught me something simple about joy and buttercream. Watching kids and adults alike reach for seconds, faces lighting up at those bright specks of color, reminded me that food does not have to be sophisticated to be unforgettable sometimes it just needs sprinkles.

Ingredients

• All-purpose flour: The backbone of your cake, providing structure while staying tender enough to crumble beautifully
• Baking powder: Essential lift so those layers rise tall and proud in the oven
• Salt: A tiny pinch that makes all the sweet flavors sing louder
• Unsalted butter: Room temperature is nonnegotiable here it creates that fluffy, creamy base we need
• Granulated sugar: Sweetness and tenderness in one crystalline package
• Large eggs: Also at room temperature so they emulsify properly into the batter
• Whole milk: Adds moisture and richness, creating the most tender crumb imaginable
• Fresh strawberries: Finely chopped so they distribute evenly without weighing down the batter
• Pure vanilla extract: The aromatic foundation that bridges strawberry and buttercream flavors
• Rainbow sprinkles: Use jimmies rather than nonpareils to prevent color bleeding into your batter
• More unsalted butter: For the buttercream, again perfectly softened for silky smooth results
• Powdered sugar: Sift it first or regret the lumpy frosting that follows
• Strawberry puree: Blended fresh berries strained until completely smooth
• Milk or cream: Only if your frosting needs adjusting to the perfect spreadable consistency

Instructions

Preheat and prepare:

Heat your oven to 350°F and grease two 8inch round pans, lining bottoms with parchment paper for easy removal later.

Whisk the dry ingredients:

Combine flour, baking powder, and salt in a medium bowl, whisking until evenly distributed.

Cream butter and sugar:

Beat butter and sugar on mediumhigh speed for 3 to 4 minutes until pale and fluffy.

Add eggs and vanilla:

Beat in eggs one at a time, then stir in vanilla until fully incorporated.

Combine wet and dry:

Alternate adding flour mixture and milk in three additions, beginning and ending with flour, mixing just until combined.

Fold in strawberries and sprinkles:

Gently fold chopped strawberries first, then carefully fold in sprinkles to prevent color bleeding.

Bake the layers:

Divide batter evenly between pans and bake 28 to 32 minutes until a toothpick comes out clean.

Cool completely:

Let cakes rest in pans for 10 minutes before turning onto wire racks to cool entirely.

Make the buttercream:

Beat butter until creamy, add powdered sugar gradually, then mix in strawberry puree and vanilla.

Adjust frosting consistency:

Add milk one tablespoon at a time if needed to reach perfectly spreadable texture.

Assemble the cake:

Spread buttercream between layers, then frost top and sides generously.

Add final touches:

Scatter extra sprinkles over the top for that festive finish that makes everyone smile.

Last summer my neighbor texted me at midnight asking for this recipe after her daughter described it as the best cake of her entire life. I sent over the ingredients list immediately, knowing exactly what kind of birthday magic was about to happen in their kitchen the next morning.

Making It Ahead

I have learned through slightly desperate party prep that the cake layers freeze beautifully when wrapped tightly in plastic and foil. Thaw them overnight in the refrigerator before frosting, and you will look like the most organized baker alive even if you are frantically making buttercream an hour before guests arrive.

Troubleshooting

If your strawberries seem especially juicy, pat them gently with paper towels before chopping to prevent soggy spots in the baked cake. And if your buttercream looks slightly curdled after adding the puree, keep beating it on medium speed for another minute or two it almost always comes back together beautifully.

Serving Ideas

This cake deserves to be the star at any birthday, celebration, or Tuesday that needs brightening up. I love serving it with fresh strawberries on the side for those who want extra fruit with their slice.

• Pair with chilled prosecco for the adults while kids enjoy strawberry milk
• Leftover frosting makes an excellent dip for fresh berries or graham crackers
• Store at room temperature for one day or refrigerate for up to four days in an airtight container

Every time I pull this cake from the oven, speckled with tiny rainbows and smelling like summer, I remember that the best recipes are the ones that make people feel something before they even take a bite.

Recipe FAQs

→ Can I use frozen strawberries instead of fresh?

Yes, frozen strawberries work well. Thaw completely and drain excess liquid before chopping for the cake batter. For the puree, blend thawed berries and strain to remove any fibrous pieces. You may need to reduce the liquid slightly to achieve the right consistency.

→ How far in advance can I make this cake?

The cake layers can be baked and wrapped in plastic up to 2 days ahead. Store at room temperature. The buttercream can be prepared 1-2 days in advance and refrigerated. Bring to room temperature and re-whip before frosting. Fully frosted cake is best enjoyed within 2 days but keeps refrigerated for up to 4 days.

→ Why do my sprinkles bleed into the batter?

Sprinkles bleed when over-mixed or when the batter is too warm. Gently fold them in at the very end using just a few strokes. Choose jimmies-style sprinkles rather than nonpareils, as they hold their color better. For extra insurance, toss them lightly in flour before adding.

→ Can I make this as cupcakes?

Absolutely. Line a muffin tin with paper liners and fill each about two-thirds full. Bake at 350°F for 18-22 minutes until a toothpick comes out clean. This recipe yields approximately 24-30 cupcakes. Frost with the same strawberry buttercream once completely cooled.

→ How do I get a deeper strawberry flavor?

Add a few drops of natural strawberry extract to either the cake batter or frosting for an intense strawberry boost. You can also reduce some strawberry puree on the stove until concentrated and syrupy, then use this concentrated puree in the buttercream for more pronounced flavor.
