What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and a satisfying texture without the fuss. The sprinkles bring that unmistakable funfetti charm, while the cream cheese frosting adds a subtle tang that cuts through the sweetness perfectly.

• For the Cake Batter:
• 2 ½ cups (312g) all-purpose flour (I prefer King Arthur for consistent results)
• 2 ½ teaspoons baking powder
• ½ teaspoon baking soda
• ½ teaspoon salt
• 1 cup (226g) unsalted butter, softened
• 1 ¾ cups (350g) granulated sugar
• 4 large eggs, room temperature
• 1 tablespoon pure vanilla extract (quality vanilla makes a difference!)
• 1 cup (240ml) buttermilk, room temperature (or use regular milk with 1 tablespoon lemon juice as a substitute)
• ¾ cup (130g) rainbow sprinkles (look for non-bleeding ones to keep colors vibrant)
• For the Rainbow Cream Cheese Frosting:
• 16 ounces (450g) cream cheese, softened (Philadelphia brand works well)
• ½ cup (113g) unsalted butter, softened
• 4 cups (480g) powdered sugar, sifted
• 2 teaspoons pure vanilla extract
• Pinch of salt
• Food coloring gel in rainbow shades (optional, but fun for that colorful swirl effect)

Equipment Needed

• 9×13 inch (23×33 cm) sheet cake pan – a reliable non-stick pan helps but lining with parchment paper ensures easy release.
• Electric mixer (stand or hand) – essential for creaming butter and beating the frosting until fluffy.
• Mixing bowls – at least two, one for dry ingredients and one for wet.
• Measuring cups and spoons – precise measurements are key for baking success.
• Rubber spatula – great for folding in sprinkles gently without overmixing.
• Cooling rack – to cool the cake completely before frosting.

If you don’t have a stand mixer, a good hand mixer works just fine. I’ve made this cake both ways without issue. For budget-friendly baking, a simple silicone spatula and a sturdy pan are your best friends. Also, keeping your cream cheese and butter at room temperature (not too soft) is a small step that makes the frosting silky smooth.

Preparation Method

1. Preheat and prep: Set your oven to 350°F (175°C). Grease your 9×13 inch sheet pan and line it with parchment paper, leaving an overhang for easy cake removal.
2. Mix dry ingredients: In a medium bowl, whisk together 2 ½ cups flour, baking powder, baking soda, and salt. Set aside.
3. Cream butter and sugar: In a large bowl, beat 1 cup softened butter with 1 ¾ cups sugar on medium speed until light and fluffy, about 3-4 minutes. This step is crucial for a tender crumb.
4. Add eggs and vanilla: Beat in eggs one at a time, ensuring each is fully incorporated before adding the next. Stir in 1 tablespoon vanilla extract.
5. Alternate adding dry ingredients and buttermilk: With mixer on low, add the dry ingredients in three parts alternating with the buttermilk (start and end with dry). Mix until just combined; overmixing will toughen the cake.
6. Fold in sprinkles: Gently fold in ¾ cup rainbow sprinkles with a spatula. Be careful not to overfold, or the colors may bleed.
7. Pour and bake: Transfer batter to the prepared pan and smooth the top. Bake for 35-40 minutes, or until a toothpick inserted near the center comes out clean. The edges should pull away slightly from the pan.
8. Cool completely: Let cake cool in the pan for 15 minutes, then lift out using parchment overhang and transfer to a wire rack until fully cooled. Frosting a warm cake will cause melting.
9. Make the frosting: Beat together 16 oz cream cheese and ½ cup butter until smooth. Gradually add 4 cups powdered sugar, then vanilla and salt, beating until creamy and spreadable.
10. Color and frost: Divide frosting into small bowls and tint each with a different food coloring gel. Dollop colors on cake and use a spatula or knife to swirl gently, creating a rainbow effect without fully blending colors.
11. Serve and enjoy: Slice generously and watch smiles light up the room!

If your sprinkles bleed too much, try folding them in last and bake immediately. Also, when frosting, keep the frosting chilled if your kitchen is warm—that helps with smooth spreading.

Cooking Tips & Techniques

Getting a moist, tender cake with vibrant sprinkles takes a few tricks I learned through trial and error. First, don’t skimp on creaming the butter and sugar—that air incorporation is what gives the cake its light texture. Also, mixing dry and wet ingredients alternately keeps the batter from becoming too dense.

One common mistake is overmixing after adding flour, which can make the cake tough. Fold in the sprinkles gently and avoid stirring too much to prevent the colors from bleeding into the batter. Using high-quality, non-bleeding sprinkles really makes a difference here.

For the frosting, room temperature cream cheese and butter are essential. Too cold and it won’t blend; too warm and it’ll be runny. Beat the frosting just until smooth to avoid air bubbles that make spreading tricky.

When frosting the cake, chilling the sheet cake for a bit can help to prevent the frosting from melting on contact, especially in warmer kitchens. I sometimes keep the cake in the fridge for 15 minutes before frosting to get a nice firm base.

Multitasking tip: While the cake bakes, you can prepare the frosting and tint it in separate bowls. That way, once the cake cools, you’re ready to decorate immediately and avoid any rushed mess.

Variations & Adaptations

• Gluten-Free Funfetti: Swap all-purpose flour for a 1-to-1 gluten-free baking flour blend. Add a teaspoon of xanthan gum if your blend doesn’t already include it to help with texture.
• Dairy-Free Version: Use dairy-free cream cheese and butter alternatives, and swap buttermilk for almond or oat milk with a tablespoon of lemon juice.
• Chocolate Funfetti: Replace ½ cup of flour with unsweetened cocoa powder for a chocolate base. Use chocolate sprinkles or mini chocolate chips for the confetti effect.
• Seasonal Fruit Addition: Try folding in fresh or frozen blueberries or raspberries for a fruity twist, similar to the fresh berries featured in the Peach Melba Pavlova. Adjust baking time slightly if fruit is added.
• Frosting Flavor Swaps: Add a teaspoon of lemon zest or a tablespoon of raspberry puree to the cream cheese frosting for a fresh twist. I’ve also tried a light lavender hint inspired by the Lavender Gin Fizz Cocktail recipe, which adds a subtle floral note.

Serving & Storage Suggestions

This cake is best served at room temperature so the frosting is soft and creamy. If you’re serving it for an Easter brunch or a spring gathering, pairing it with a light beverage like a sparkling water with fresh lemon or a fruity iced tea complements the sweetness nicely.

Leftovers keep well covered in the fridge for up to 4 days. To avoid drying out, wrap the cake tightly with plastic wrap or store in an airtight container. When you’re ready to enjoy again, let the cake sit at room temperature for about 30 minutes before serving for the best texture.

You can also freeze individual slices wrapped tightly in plastic and foil for up to 2 months. Thaw overnight in the fridge and bring to room temperature before eating.

Fun fact: The flavors actually mellow and deepen after a day or two, making the cake even more delightful. The cream cheese frosting softens into a luscious layer that melts on your tongue.
