Good to know

Chef's tip

🎨 For even brighter colors, use gel food coloring rather than liquid! And if your cake layers rise too much, level them with a knife before assembling for a neat finish. 🔪✨

Freezing : Can you freeze this recipe?

Yes

Unfrosted cake layers freeze very well, up to 2-3 months, wrapped individually in plastic wrap. The assembled frosted cake can be frozen for up to 1 month.

Storage : How long does it keep?

Keeps 3 to 4 days max at room temperature in an airtight container. Refrigeration can harden the frosting and dry out the cake.

Making ahead : Can you make it the day before?

Yes

The cake layers can be made the day before, cooled, then wrapped in plastic wrap. Assemble with the frosting just before serving.

Reheating : How do you reheat it?

Not applicable. Rainbow Cake is eaten at room temperature.

Variations

Decorate with edible confetti.
Refrigerate for 1 hour so the cake holds together well.
Change up the order of the colors.

Mistakes to avoid

Coloring without mixing: mix until the colors are vivid.
Frosting warm cake layers: let them cool on a rack.
Serving without resting: 1 hour in the refrigerator.

Frequently asked questions

How do you make a rainbow cake?

Prepare a sponge cake batter, divide it into 6 colored portions, bake each for 12 minutes at 180 °C, let cool, then stack the layers with a buttercream frosting made with powdered sugar before chilling for 1 hour.

In what order should you stack the colors?

Place the purple layer, spread a thin coat of frosting, then stack the blue, green, yellow, orange and red layers one after another, gluing them together with frosting.

How do you make the frosting?

Whisk 250 g of softened butter with 500 g of powdered sugar, add 4 tablespoons of milk and the vanilla, and beat until you get a smooth, creamy frosting.

How long should the cake rest?

Place the frosted cake in the refrigerator for at least 1 hour so it holds together well before serving. Decorate with edible confetti.
