Ingredients You’ll Need
Every ingredient in this Funfetti Cookie Cake Recipe plays a vital role in creating that perfect balance of flavor and texture, while also adding bursts of color and fun. From the rich butter to the joyful sprinkles, each component is essential.
- All-purpose flour (2 1/2 cups): Provides the structure that holds the cookie cake together with a tender crumb.
- Baking soda (1 tsp): Acts as a leavening agent to give the cake a light, airy texture without being too cakey.
- Salt (1/2 tsp): Enhances all the flavors, balancing the sweetness perfectly.
- Unsalted butter, softened (1 cup): Adds richness and helps create the cookie cake’s signature soft and chewy texture.
- Granulated sugar (1 cup): Sweetens and helps with the cookie’s slight crisp on the edges.
- Brown sugar, packed (1/2 cup): Introduces a subtle molasses flavor and additional moisture for chewiness.
- Large eggs (2): Bind everything together and add moisture for that perfect consistency.
- Vanilla extract (2 tsp): Infuses the dough with a warm, comforting aroma and taste.
- Rainbow sprinkles (1 cup): The star of the show, lending a cheerful pop of color and a little crunch in every bite.
- White chocolate chips (1/2 cup, optional): Adds extra sweetness and creamy bites that melt delightfully.
- Powdered sugar (2 cups): For the luscious frosting that crowns this Funfetti delight.
- Milk (2 tbsp or more): Used to adjust the frosting to the perfect spreadable consistency.
- Extra vanilla extract (1 tsp): Brings the frosting to life with its delicate flavor.
- Pinch of salt: Keeps the frosting balanced and prevents it from being overly sweet.
- Extra rainbow sprinkles: For that final festive garnish that makes this cookie cake pop visually.
How to Make Funfetti Cookie Cake Recipe
Step 1: Prep Your Pan and Oven
Start by preheating your oven to 350°F (175°C). This ensures the perfect heat level to bake your cookie cake evenly. Grease a 9-inch round cake pan and line it with parchment paper or use a non-stick baking spray so your cookie cake releases easily and stays intact.
Step 2: Mix Dry Ingredients
Whisk together the all-purpose flour, baking soda, and salt in a medium bowl. This blend of dry ingredients will give your cake the right texture and a slight lift making each slice soft but not doughy.
Step 3: Cream Butter and Sugars
In a large mixing bowl, beat the softened butter with both granulated and brown sugars until creamy and smooth—about 2 to 3 minutes. This step is crucial for that light, fluffy base and contributes to the cookie cake’s irresistible chewiness.
Step 4: Add Eggs and Vanilla
Beat in the eggs one at a time, making sure each is fully incorporated before adding the next. Then, stir in the vanilla extract to infuse your cookie cake with that warm, inviting aroma we all love.
Step 5: Combine Wet and Dry Mixtures
Gradually mix the flour mixture into the wet ingredients. Be gentle and stir just until all the dry ingredients are absorbed. Overmixing here can make your cookie cake tough, so keep it tender by stopping as soon as the flour disappears.
Step 6: Fold in Funfetti and Chocolate Chips
Now for the fun part—gently fold in the rainbow sprinkles and white chocolate chips (if you’re using them). Make sure these colorful gems and melty chips are evenly distributed, so every bite delivers joy and sweetness.
Step 7: Spread and Bake
Spread your cookie dough evenly into the prepared pan, smoothing the top with a spatula. Pop it into the oven and bake for about 18 to 20 minutes, or until the edges are lightly golden and a toothpick inserted in the center comes out clean.
Step 8: Cool Completely
After baking, allow your cookie cake to cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely. This step ensures your frosting will spread perfectly without melting away.
Step 9: Frost and Decorate
While your cookie cake cools, prepare the frosting by beating together softened butter, powdered sugar, milk, vanilla extract, and a pinch of salt until smooth and fluffy. Spread it generously on your cooled cookie cake and sprinkle extra rainbow sprinkles on top for that perfect finish.
How to Serve Funfetti Cookie Cake Recipe

Garnishes
The easiest way to elevate your Funfetti Cookie Cake Recipe is with colorful garnishes. A few extra rainbow sprinkles scattered on top of the frosting add that final playful look. If you want an added touch, consider edible glitter or mini candies for extra sparkle and charm.
Side Dishes
Serve your cookie cake with simple sides that complement its sweetness. A scoop of vanilla ice cream, fresh berries, or even a dollop of whipped cream balance the richness beautifully. For a cozy vibe, a glass of cold milk or a warm cup of coffee is the perfect pairing.
Creative Ways to Present
Want to impress your guests? Place the cookie cake on a decorative cake stand or slice it into fun shapes with cookie cutters after baking. You can even personalize each slice with piped icing messages or edible markers for birthdays or special occasions. The Funfetti Cookie Cake Recipe works beautifully as a centerpiece for any celebration.
Make Ahead and Storage
Storing Leftovers
Your Funfetti Cookie Cake keeps wonderfully when stored properly. Wrap it tightly with plastic wrap or place it in an airtight container. Kept at room temperature, it stays fresh for up to 3 days, perfect if you want to savor the magic slowly.
Freezing
To enjoy your funfetti cookie cake later, freezing is a fantastic option. Wrap the uncut cake or individual slices in plastic wrap and then foil. Store in the freezer for up to 2 months. Just thaw overnight in the refrigerator before serving to bring back that fresh-baked texture.
Reheating
If you want to enjoy your cookie cake warm, a quick zap in the microwave for 15-20 seconds or a brief stint in a low-temperature oven refreshes the softness and highlights the melty chocolate chips and frosting perfectly.
FAQs
Can I use gluten-free flour in this Funfetti Cookie Cake Recipe?
Absolutely! Just swap the all-purpose flour with a gluten-free blend that contains xanthan gum for the best structure. You might need to adjust baking time slightly, so keep an eye on the cake as it bakes.
What if I don’t have white chocolate chips?
No worries! You can leave them out entirely or substitute with regular chocolate chips or butterscotch chips to suit your taste. The cookie cake will still be deliciously fun and colorful.
How do I make the frosting dairy-free?
Use a dairy-free butter substitute and a dairy-free milk alternative to keep this frosting vegan-friendly. The texture may vary slightly but it’ll still be creamy and delightful.
Can I make mini Funfetti cookie cakes instead of one big one?
Yes, mini versions are adorable! Use muffin tins lined with paper cups, bake for about 10-12 minutes, and keep an eye on them since smaller cakes bake faster. They make perfect party favors or individual treats.
Is this Funfetti Cookie Cake Recipe suitable for kids?
Definitely! Kids love the colorful sprinkles and the soft, sweet texture. Plus, they can join in decorating with frosting and extra sprinkles, making it a fun baking activity for the whole family.
