The Magic of the Rainbow Cake: Detailed Procedure
Making a Rainbow Cake is a fun experience and the result is always surprising. Follow these steps to create a colorful masterpiece:
Prepare oven and pans: Preheat the oven to 340°F. Grease and line with parchment paper 8.5-inch pans.
Combine dry ingredients: Sift together flour, salt, and baking powder.
Prepare the base batter: In a stand mixer (or with electric whisks), beat softened butter and sugar until light and fluffy.
Add liquids and dry: Gradually incorporate egg whites and vanilla extract. Then, alternately add half of the flour, half of the milk, the remaining flour, and the rest of the milk, mixing until a homogeneous batter is obtained.
Color and divide: Divide the batter into six equal parts. Add a gel food coloring (red, orange, yellow, green, blue, purple) to each portion, mixing well to obtain bright colors.
Bake: Pour each colored batter into the pans and bake for about 15 minutes.
Cool: Allow cakes to cool for 10 minutes in the pan, then remove them to a rack. For a precise cut, wrap and chill the baked layers in the fridge.Sugar syrup: In a small pot, bring water and sugar to 250°F without stirring.
Beat the yolks: In a stand mixer, start to whip the yolks.
Combine and cool: Pour the syrup in a thin stream over the whipped yolks, continuing to whip until completely cool and a foamy mixture is obtained.
Work the butter: In a separate bowl, make the butter creamy at room temperature with a spatula.
Blend the cream: Incorporate the vanilla seeds into the yolk mixture, then gradually add the butter, whipping until a smooth cream is obtained.
Rest: Place the buttercream in the fridge for at least 30 minutes.Level the layers: Trim the surface of each cake layer with a long knife.
Fill: Place the first layer, fill with cream, and continue alternating colored cake layers and cream, following the order of the rainbow.
Final coating: Apply a thin layer of cream (crumb coat), chill, then cover the entire cake with more cream or white fondant.
Decorate: Decorate as desired with smarties, colored fondant, or other toppings to recall the rainbow.
In-depth: Ingredients and Substitutions
For a perfect Rainbow Cake, the quality of the ingredients is essential.
Butter: Use good quality butter at room temperature, both for the batter and the cream. Do not use margarine, as the flavor and texture would suffer.
Food coloring: Gel food colorings are best for this recipe, as they are very concentrated and do not alter the batter’s consistency, ensuring bright and saturated colors. Liquid ones may require a greater quantity and make the batter too runny.
Milk: You can use whole milk, semi-skimmed milk, or even plant-based drinks like soy or almond milk for a lactose-free version.
Cream: The Italian buttercream (as described) is ideal for its stability, velvety texture, and white color that enhances the layers. Alternatively, you can opt for a cream cheese frosting for a fresher and less sweet taste.
Storage
The Rainbow Cake can be stored in the refrigerator for 3-4 days, covered with cling film or under a cake dome to prevent it from drying out. It is advisable to take it out of the fridge at least 30 minutes before serving to enjoy it at its best. You can also freeze the already cooked cake layers (without cream) wrapped individually in cling film for up to a month, thawing them at room temperature before filling.
Variants
Added flavors: You can enhance the batter with essences other than vanilla, like almond, lemon, or orange. Alternative fillings: Besides buttercream or cheese, you can use white chocolate ganache, whipped cream, or light fruit preserves for the layers. The important thing is that the cream is not too dark so as not to cover the rainbow colors. Decorations: Besides smarties and fondant, use white chocolate flakes, colored sprinkles, or fresh fruit arranged creatively.
Recipe History
The Rainbow Cake, or rainbow cake, has become a viral phenomenon in recent years, but its origins are more complex than one might think. Layered colored cakes already existed in some cultures, but the modern and iconic version, with six distinct layers and vibrant colors, was popularized in the United States at the beginning of the 21st century, mainly thanks to cooking blogs and social media. Although there is no single recognized “inventor,” its global spread has been accelerated by its incredible photogenic nature, becoming a symbol of joy, inclusivity, and celebration. It is a dessert that perfectly embodies the digital age, where aesthetics and visual sharing play a fundamental role.
FAQ (Questions and Answers)
Can I use liquid food coloring?

Preparation takes time, about 2-3 hours between batter, baking, and cooling the layers. Assembling and decorating may take another 1-2 hours. It is a dessert that lends itself well to being prepared in stages, spreading the work over two days (e.g., baking the layers on the first day and filling/decorating on the second).
Is the Rainbow Cake difficult to make for a beginner?
It’s not difficult, but it requires patience and precision, especially in dividing the batter and leveling the layers. By carefully following the steps and not rushing, even a beginner can achieve excellent results. The secret is to have fun with the colors!
