Ingredients You’ll Need
This ingredient list is marvelously simple yet each component is absolutely essential, coming together for a cake that’s as stunning as it is delicious. Every ingredient has a purpose, from creating a soft, fluffy base to giving that signature Funfetti flair!

How to Make Funfetti Flag Cake
Step 1: Prepare Your Pan & Preheat the Oven
Start by preheating your oven to 350°F (175°C) and generously greasing a 9×13-inch baking pan. This is essential to prevent sticking and ensures those beautiful cake edges release perfectly. Give the pan a good mist or swipe with oil, especially in the corners!
Step 2: Mix the Funfetti Cake Batter
Empty the white cake mix into a large mixing bowl, then add the egg whites, water, and vegetable oil right as the instructions on the box suggest. Beat everything together on medium speed until smooth (usually about 2 minutes). Now, the fun part—gently fold in your rainbow jimmies so every slice has cheerful bursts of color. Be careful not to overmix; this keeps the colors vibrant.
Step 3: Bake and Cool the Cake
Pour the batter into your prepared pan, making sure it’s spread evenly. Slide it into the oven and bake for 30 to 35 minutes, or until a toothpick poked in the center comes out clean. While your kitchen fills with that nostalgic cupcake aroma, resist sneaking a peek—consistent oven heat helps the Funfetti Flag Cake rise perfectly. Once done, let the cake cool completely on a wire rack before decorating.
Step 4: Make the Fluffy Cream Cheese Whipped Frosting
In a mixing bowl, beat the softened cream cheese until perfectly smooth—no lumps allowed! Next, add the powdered sugar and vanilla extract, then beat again until creamy. In a separate, clean bowl, whip the heavy cream until stiff peaks form (don’t rush this, fluffy frosting is worth it). Finally, gently fold the whipped cream into the cream cheese mixture, being careful to keep things airy. This frosting is what makes every bite of Funfetti Flag Cake extra special.
Step 5: Frost and Decorate Your Funfetti Flag Cake
Spread your luscious frosting evenly across the cooled cake, making sure to get all the way to the edges. For the grand finale, arrange the blueberries in the upper left corner to mimic the stars section of the flag. Then, create rows of sliced strawberries for the red stripes, leaving that gorgeous white frosting in between for contrast. The best part? No two flags are ever quite alike!
How to Serve Funfetti Flag Cake
Garnishes
If you want to add extra flair, sprinkle a few more rainbow jimmies along the edges or add a dollop of whipped cream on each slice. For a super festive finish, a light dusting of powdered sugar over the berries right before serving adds a little sparkle that catches the eye!
Side Dishes
Serve your Funfetti Flag Cake with a simple bowl of fresh berries on the side, a nice glass of cold milk, or even a scoop of vanilla ice cream. If it’s a barbecue or summer party, guests will love the creamy cake alongside crisp, juicy watermelon or a tart lemonade.
Creative Ways to Present
Try turning your Funfetti Flag Cake into individual flag cupcakes, or use a star-shaped cookie cutter to punch out fun, patriotic shapes. You can also crumble leftovers into parfait glasses with extra fruit and whipped cream for a no-fuss, layered treat!
Make Ahead and Storage
Storing Leftovers
Any leftover Funfetti Flag Cake can be tightly covered and refrigerated for up to 3 days. The cream cheese whipped frosting keeps the cake moist, and the berries retain their freshness when chilled—just be sure to seal the pan well so nothing dries out.
Freezing
You can freeze undecorated Funfetti Flag Cake layers for up to two months. Simply wrap the cooled cake tightly in plastic wrap and then foil. For best results, add the frosting and fruit decorations after thawing so everything stays vibrant and fresh.
Reheating
This cake is best enjoyed chilled or at cool room temperature, so no reheating is necessary! If you’ve stored it in the refrigerator, let slices sit out for about 15 minutes before serving to allow the frosting to become pillowy and soft again.
FAQs
Can I make Funfetti Flag Cake with homemade cake instead of a mix?
Absolutely! If you have a favorite white cake recipe, go ahead and use it as your base—just be sure to use egg whites for the brightest Funfetti effect. The magic is in the sprinkles and the decoration, so homemade or boxed both work beautifully.
What kind of sprinkles work best for Funfetti Flag Cake?
Jimmies are the best choice because they hold their shape and color during baking. Avoid nonpareils, since they can bleed and create a muddled look in the batter.
Can I make Funfetti Flag Cake ahead of time?
Yes! You can bake the cake up to a day in advance and frost it just before serving for the freshest look. Feel free to store it in the fridge overnight; simply add the fruit on the day of your event to keep everything looking perky and bright.
How do I keep the strawberries from getting soggy?
Pat the strawberry slices dry with a paper towel before arranging them on your cake. This simple step keeps them juicy but not watery, so your stripes stay bold and the frosting remains intact.
Is Funfetti Flag Cake suitable for kids’ parties?
Definitely! Kids and adults alike are drawn to those colorful sprinkles, and the berry flag design is always a huge hit. You can even let little helpers add the sprinkles or help decorate the flag for a memorable kitchen activity.
Final Thoughts
There’s just something irresistible about Funfetti Flag Cake—its playful colors, luscious frosting, and fresh berry flourish combine for smiles with every slice. Give it a try at your next celebration and watch it disappear in a flash!
