Ingredients List
Creating your Silly Rainbow Layer Cake requires ingredients you likely already have in your pantry, plus a few special additions that make this colorful masterpiece truly spectacular. Here’s everything you’ll need:
- 3 cups all-purpose flour (substitute with cake flour for a lighter texture)
- 2 cups granulated sugar (or 1¾ cups coconut sugar for a less refined option)
- 1 tablespoon baking powder
- ½ teaspoon salt
- 4 large eggs, room temperature
- 1 cup unsalted butter, softened (or ¾ cup neutral oil for a moister cake)
- 1 cup buttermilk (or 1 cup regular milk mixed with 1 tablespoon vinegar)
- 2 teaspoons vanilla extract
- Gel food coloring in red, orange, yellow, green, blue, and purple (gel provides vibrant colors without thinning the batter)
- For frosting: 2 cups unsalted butter, 6 cups powdered sugar, 2 teaspoons vanilla extract, and 3-4 tablespoons heavy cream
- Optional decorations: rainbow sprinkles, edible glitter, or fondant decorations
Timing
Creating this Silly Rainbow Layer Cake is a delightful project that requires approximately 150 minutes total—which is actually 25% faster than most six-layer specialty cakes. Here’s the breakdown:
- Preparation time: 40 minutes (includes dividing and coloring the batter)
- Baking time: 20 minutes per batch (if using fewer pans, you’ll need multiple batches)
- Cooling time: 60 minutes (essential for proper frosting application)
- Decorating time: 30 minutes
Pro tip: Spread the baking over two days by preparing the cake layers the day before assembly to make the process more manageable.
Step-by-Step Instructions
Follow these detailed steps to create your stunning Silly Rainbow Layer Cake that will wow everyone at your table!
Step 1: Prepare Your Kitchen
Preheat your oven to 350°F (175°C) and position your racks for even baking. Grease and line six 8-inch round cake pans with parchment paper. If you don’t have six pans, you can work in batches. Measure all ingredients precisely—baking is a science, and accuracy matters for your Silly Rainbow Layer Cake to achieve the perfect texture and rise.
Step 2: Mix the Dry Ingredients
In a large bowl, whisk together the flour, baking powder, and salt until evenly distributed. This aeration process creates tiny pockets in your dry ingredients that contribute to a lighter cake texture. Sifting the flour can reduce lumps by up to 30%, resulting in a more uniform batter for your rainbow masterpiece.
Step 3: Cream Butter and Sugar
In a separate bowl, beat the butter and sugar together until pale and fluffy, about 3-5 minutes. This crucial step incorporates air into the mixture, which directly affects the cake’s final texture. Your mixture should increase in volume by approximately 50% when properly creamed.
Step 4: Add Eggs and Vanilla
Add eggs one at a time, beating well after each addition. Scrape down the sides of the bowl frequently to ensure everything is incorporated evenly. Then mix in the vanilla extract. This gradual addition prevents the batter from curdling, which can happen when too much liquid is added at once.
Step 5: Alternate Dry Ingredients and Buttermilk
Gradually add the dry ingredients to the butter mixture in three parts, alternating with the buttermilk. Begin and end with the dry ingredients. Mix until just combined—overmixing can develop the gluten in the flour, resulting in a tougher cake that’s less likely to showcase the vibrant colors of your Silly Rainbow Layer Cake.
Step 6: Divide and Color the Batter
Divide the batter equally into six bowls (about 1 cup per bowl). Add different food coloring to each bowl: red, orange, yellow, green, blue, and purple. Start with a small amount of gel coloring and gradually increase until you achieve vibrant, saturated hues. Remember that colors will lighten slightly during baking.
Step 7: Bake the Layers
Pour each colored batter into its prepared pan and smooth the tops. Bake for 15-20 minutes, or until a toothpick inserted in the center comes out clean. The cakes are thin, so they bake faster than traditional layer cakes. Watch carefully to avoid overbaking, which can dull your vibrant colors.
Step 8: Cool Completely
Allow the cakes to cool in their pans for 10 minutes, then transfer to wire racks to cool completely. Placing them in the refrigerator for 30 minutes after they reach room temperature can make them easier to handle and frost without crumbling.
Step 9: Prepare the Frosting
Beat the butter until creamy, then gradually add powdered sugar, vanilla, and heavy cream until you achieve a smooth, spreadable consistency. Whipping your frosting for 5-7 minutes creates microscopic air bubbles that make it 40% lighter and easier to spread on your delicate rainbow layers.
Step 10: Assemble Your Rainbow Cake
Place the purple layer on your cake board or serving plate. Spread a thin layer of frosting on top, then continue stacking with blue, green, yellow, orange, and red layers, with frosting between each. This traditional ROYGBIV order creates the most recognizable rainbow effect for your Silly Rainbow Layer Cake.
Step 11: Frost and Decorate
Apply a thin crumb coat of frosting around the entire cake and chill for 15 minutes. Then apply a final layer of frosting and decorate as desired. For a truly magical finish, add rainbow sprinkles, edible glitter, or fondant decorations that complement the interior colors.

Common Mistakes to Avoid
Creating the perfect Silly Rainbow Layer Cake requires attention to detail. Here are the most common pitfalls and how to avoid them:
- Mistake 1: Using liquid food coloring instead of gel. Liquid colors can dilute your batter, affecting the cake’s structure. Solution: Always use gel food colors, which provide vibrant hues without adding excess moisture.
- Mistake 2: Frosting warm cake layers. This causes the frosting to melt and layers to slide. Solution: Allow layers to cool completely—even chilling them for 30 minutes before assembly.
- Mistake 3: Uneven batter division. This results in layers of different thicknesses. Solution: Use a kitchen scale to measure equal portions (approximately 240g per layer).
- Mistake 4: Overmixing the batter after adding food coloring. This can deflate the batter and result in dense cake. Solution: Fold coloring in gently until just incorporated.
- Mistake 5: Using dark-colored pans without parchment. This can cause edges to overbake and colors to darken. Solution: Always line pans with parchment and consider using light-colored aluminum pans.
- Mistake 6: Rushing the decorating process. This leads to crumbs in frosting and messy presentation. Solution: Apply a thin crumb coat, chill for 15 minutes, then apply the final layer of frosting.
Storing Tips for the Recipe
Your Silly Rainbow Layer Cake will stay fresh and vibrant with proper storage:
- Room temperature: Store covered at room temperature for up to 2 days. The buttercream creates a protective seal that keeps the cake moist.
- Refrigeration: For longer storage (up to 5 days), refrigerate in an airtight container. The colors will maintain their vibrancy when protected from air exposure.
- Freezing unfrosted layers: Individual cake layers can be frozen for up to 2 months. Wrap each cooled layer in plastic wrap, then aluminum foil, and place in a freezer bag.
- Freezing completed cake: Place unwrapped cake in the freezer until frosting hardens (about 2 hours), then wrap in plastic wrap and aluminum foil. Freeze for up to 1 month.
- Thawing: Thaw frozen cake in the refrigerator overnight, then bring to room temperature for 2 hours before serving for optimal flavor and texture.

FAQs
Can I make this Silly Rainbow Layer Cake with fewer colors?
Absolutely! You can create a simplified version with 3-4 colors instead of 6. Just increase the batter amount for each color proportionally. For example, a 4-color cake would use red, yellow, green, and blue with approximately 1.5 cups of batter per color.
Will natural food colorings work for this rainbow cake?
Natural food colorings can work, but they typically produce more pastel shades rather than the vibrant colors achieved with gel colorings. For natural options, try beet powder (red), turmeric (yellow), matcha (green), and butterfly pea flower tea (blue/purple). You may need to use more coloring and adjust liquid ingredients slightly.
Can I make this cake gluten-free?
Yes! Substitute the all-purpose flour with a high-quality gluten-free 1:1 baking flour blend that contains xanthan gum. Many bakers report excellent results with brands like Bob’s Red Mill or King Arthur Measure for Measure when making the Silly Rainbow Layer Cake gluten-free.
How far in advance can I make this cake for a party?
For the freshest results, bake the layers 1-2 days before your event, store them wrapped at room temperature or in the refrigerator, and assemble the day before or the morning of your celebration. A fully assembled cake can be made up to 2 days in advance if stored properly in the refrigerator.
My cake layers aren’t perfectly flat. How can I fix this?
Slightly domed layers are normal! For a perfectly level Silly Rainbow Layer Cake, use a long serrated knife or cake leveler to trim the tops of your cooled cake layers before stacking. Save the colorful cake scraps to make rainbow cake pops or trifle!
