Rainbow Celebration Cake

A joyful six-layer vanilla rainbow cake filled and covered with silky sweet buttercream and finished with playful rainbow sprinkles.

This is a proper celebration cake — sweet, nostalgic and unapologetically fun. Each colourful layer is soft and fluffy, stacked with generous vanilla frosting and finished with piped swirls for that classic party look.

It’s the kind of cake children adore and adults secretly love.

Perfect for:

• Birthday parties

• Kids’ celebrations

• Baby showers

• Colour-themed events

• Anyone who wants a bold, happy centrepiece

Serves 16–20 slices.

Handmade in London by Marta’s Kitchen.

✨ Bright. Sweet. Full of celebration.
