Funfetti Layer Cake with Chocolate Frosting

Instructions

Part 1: Prepare the Funfetti Cake Layers

1. Preheat your oven to 350°F (175°C). Grease and flour two 8-inch round cake pans and two 6-inch round cake pans. Line the bottoms with parchment paper.
2. In a medium bowl, whisk together the sifted flour, baking powder, and salt. Set aside.
3. In a large bowl, using an electric mixer on medium speed, cream the softened butter and granulated sugar together until light and fluffy, about 3-5 minutes.
4. Add the eggs one at a time, beating well after each addition until fully incorporated. Scrape down the sides of the bowl as needed.
5. Beat in the vanilla extract.
6. With the mixer on low speed, gradually add the dry ingredients to the wet ingredients in three additions, alternating with the milk in two additions, beginning and ending with the dry ingredients. Mix until just combined; do not overmix.
7. Gently fold in the rainbow sprinkles by hand until evenly distributed.
8. Divide the batter evenly among the prepared cake pans. For the 8-inch pans, you’ll likely have about 2 1/2 to 3 cups of batter per pan. For the 6-inch pans, about 1 1/2 to 2 cups per pan.
9. Bake the 8-inch layers for 30-35 minutes and the 6-inch layers for 25-30 minutes, or until a wooden skewer inserted into the center comes out clean.
10. Remove cakes from the oven and let them cool in the pans for 10-15 minutes before inverting them onto a wire rack to cool completely. Ensure cakes are completely cool before frosting.

Part 2: Prepare the Chocolate Buttercream Frosting

1. In a large bowl, using an electric mixer on medium-high speed, beat the softened butter for 3-5 minutes until very light and fluffy. This step is crucial for a light buttercream.
2. Gradually add the sifted powdered sugar, 1 cup at a time, mixing on low speed until combined, then increasing to medium-high.
3. Add the sifted cocoa powder, vanilla extract, and salt. Mix on low speed until combined, then increase to medium-high and beat for another 1-2 minutes.
4. With the mixer on low speed, gradually add the heavy cream or milk, a tablespoon at a time, until the frosting reaches your desired consistency. For a thicker frosting, use less liquid; for a thinner, smoother frosting, add a bit more. Beat on medium-high for 2-3 minutes until light, fluffy, and smooth.

Part 3: Assemble the Tiered Cake

1. Once the cake layers are completely cooled, use a serrated knife or cake leveler to level the tops of each cake layer, creating flat surfaces.
2. Place one 8-inch cake layer on your serving plate or cake stand. Spread about 1/2 cup of chocolate buttercream evenly over the top.
3. Place the second 8-inch cake layer on top. Apply a thin layer of frosting all around the sides and top of the 8-inch base cake. This is your “crumb coat,” which traps any loose crumbs. Chill the cake in the refrigerator for 20-30 minutes to set the crumb coat.
4. While the base cake chills, repeat the process with the 6-inch cake layers: place one 6-inch layer on a separate small plate or cardboard round, spread with frosting, top with the second 6-inch layer, and apply a crumb coat. Chill the 6-inch cake as well.
5. Once the crumb coats are set, retrieve the 8-inch cake. Apply a thicker, even layer of chocolate buttercream to the top and sides, smoothing it with an offset spatula or bench scraper.
6. Retrieve the 6-inch cake. Apply a thicker, even layer of chocolate buttercream to the top and sides of this smaller cake, smoothing it out.
7. To assemble the tiers: Insert 3-4 cake dowels or thick straws into the center of the 8-inch base cake, arranging them in a circle slightly smaller than the diameter of the 6-inch cake. Trim the dowels so they are flush with the top surface of the 8-inch cake. These will support the upper tier.
8. Carefully lift the 6-inch frosted cake (it helps to use a wide spatula or a second small cake board underneath) and center it on top of the 8-inch base cake, resting it on the dowels.
9. Use the remaining chocolate buttercream to pipe decorative borders or swirls as desired. A shell border or rope border around the base of the 6-inch tier and the bottom of the 8-inch tier adds a professional touch.
10. Garnish with additional rainbow sprinkles if desired, especially around the base of the top tier or dusted on top.
11. Refrigerate the finished cake for at least 30 minutes before serving to allow the frosting to firm up.

Cooking Tips and Variations

For the Sprinkles: Use good quality, sturdy sprinkles like jimmies or confetti-style sprinkles for best results. Avoid nonpareils as they tend to bleed color more readily. Add them as the very last ingredient to your batter and fold them in gently by hand to minimize color bleeding. If you’re concerned about bleeding, you can also toss the sprinkles in a teaspoon of flour before adding them to the batter.

For the Cake: Do not overmix the cake batter once the flour is added; this can develop the gluten too much, leading to a tough cake. Mix until just combined. Ensure all your cold ingredients (butter, eggs, milk) are at room temperature. This helps them emulsify properly, creating a smoother batter and a more tender cake. Always cool your cake layers completely before frosting. Warm cakes will melt your frosting and lead to a messy situation.

For the Frosting: Sift both your powdered sugar and cocoa powder to prevent lumps in your buttercream. Beat the butter for a full 3-5 minutes until it’s very light and fluffy before adding any other ingredients; this incorporates air and gives your frosting a smooth, creamy texture. Adjust the consistency with heavy cream or milk, adding a tablespoon at a time, until it’s perfect for spreading and piping. A pinch of salt enhances the chocolate flavor.

Variations:

• Different Sprinkles: Experiment with different sprinkle colors or shapes for themed parties (e.g., pastel sprinkles for Easter, red and green for Christmas).
• Cream Cheese Frosting: For a tangier twist, swap out the chocolate buttercream for a chocolate cream cheese frosting. Ensure it’s firm enough for tiered cake construction.
• Ganache Drip: Instead of a full chocolate frosting, you could use a vanilla buttercream and add a chocolate ganache drip down the sides of the cake for an elegant look.
• Filled Layers: Add a layer of raspberry jam, chocolate ganache, or even a different type of fruit curd between the cake layers for an extra burst of flavor.
• Mini Cakes: Use smaller cake pans (e.g., 4-inch) to make adorable individual funfetti cakes with chocolate frosting.
• Cupcakes: This funfetti cake batter is excellent for cupcakes! Bake for 18-22 minutes and frost with the chocolate buttercream.

Troubleshooting:

• Cake Sinks in the Middle: Could be due to overmixing, oven door opening too early, or incorrect leavening. Ensure ingredients are fresh and follow instructions carefully.
• Frosting Too Thin/Thick: Adjust consistency by adding more sifted powdered sugar for thickness or more liquid (milk/cream) for thinness, one tablespoon at a time.
• Bleeding Sprinkles: Ensure sprinkles are added at the very end of mixing and folded in gently. High-quality sprinkles also help.

Storage and Reheating

Storage: This Funfetti Layer Cake with Chocolate Frosting can be stored at room temperature for up to 2 days if covered tightly with a cake dome or plastic wrap. For longer storage, refrigerate the cake. Place the cake in an airtight container or cover it well with plastic wrap to prevent it from drying out or absorbing refrigerator odors. It will keep well in the refrigerator for up to 5 days.

Make-Ahead Tips:

• The cake layers can be baked up to 2-3 days in advance. Once completely cooled, wrap each layer tightly in plastic wrap and store at room temperature or in the refrigerator. For longer storage, freeze the wrapped layers for up to 1 month. Thaw at room temperature before frosting.
• The chocolate buttercream can be made up to 3 days in advance. Store it in an airtight container in the refrigerator. Before using, let it come to room temperature and then re-whip it with an electric mixer for a few minutes until light and fluffy again. You might need to add a tablespoon of milk or cream to achieve the perfect consistency.

Reheating/Serving: If the cake has been refrigerated, it’s best to allow it to come to room temperature for at least 1-2 hours before serving. This allows the cake layers to soften and the buttercream to become creamy again, ensuring the best flavor and texture. Do not microwave the cake to “reheat” as this can dry it out and melt the frosting.

Frequently Asked Questions

How do I prevent the sprinkles from bleeding color into the cake batter?

To prevent sprinkles from bleeding, use good quality jimmie or confetti-style sprinkles rather than nonpareils, as these tend to be more colorfast. Add them to the batter as the absolute last ingredient, folding them in gently and quickly by hand. Avoid overmixing once the sprinkles are added. Some bakers also lightly toss their sprinkles in a teaspoon of flour before adding them to the batter, which can create a barrier against moisture and color bleed.

Can I make this cake without it being tiered?

Absolutely! This recipe can easily be made as a single two-layer 8-inch cake. Simply use two 8-inch cake pans and divide the full batter between them. You will likely have leftover frosting, or you can scale down the frosting recipe slightly. All other instructions for baking and frosting will remain the same, just without the need for dowels or stacking a second tier.

What type of cocoa powder is best for the chocolate buttercream?

For a rich, dark chocolate flavor and color, we recommend using unsweetened natural cocoa powder or Dutch-processed cocoa powder. Dutch-processed cocoa powder is less acidic and often results in a darker color and smoother flavor. Either will work wonderfully, but make sure it’s unsweetened to control the sugar content in your frosting. Sifting the cocoa powder is crucial to avoid lumps.
