Introduction

This eggless rainbow cake is a vibrant and delightful treat that’s perfect for celebrations or whenever you want to brighten up your day. Made with yogurt and flavored with vanilla, each colorful layer bakes up moist and tender, topped with a creamy buttercream frosting.

A tall round cake with six visible layers inside, each layer a different bright color from bottom to top: purple, dark blue, green, yellow, orange, and red. Each colorful layer is separated by a thin white cream layer. The outside of the cake is coated with smooth white frosting and topped with colorful sprinkles forming a ring around the edge. The cake sits on a white marble plate with some sprinkles scattered on the white marbled surface below. To the left, there is a slice of the same cake on a white plate.

Ingredients

4 ½ cups (540g) all purpose flour (maida)
3 teaspoons (12g) baking powder
3 cups (855g) yogurt
1 ½ teaspoons (9g) baking soda
2 ¼ cups (450g) castor sugar
1 ½ cups (360mL) vegetable oil
3 teaspoons (15mL) vanilla extract
VIBGYOR gel food colors
1 ½ cups (300g) softened butter (for frosting)
3 teaspoons (15mL) vanilla extract (for frosting)
3 cups (390g) icing sugar, sifted
Rainbow sprinkles (to garnish)

Instructions

Step 1: Preheat your oven to 180°C and line 8-inch round cake pans with parchment paper.
Step 2: In a bowl, whisk together castor sugar and vegetable oil until pale and well combined. Add yogurt and vanilla extract, mixing until smooth.
Step 3: In a separate bowl, whisk together flour, baking soda, and baking powder. Sift the dry ingredients into the wet mixture and gently fold until just combined, avoiding overmixing.
Step 4: Divide the batter evenly into six portions. Gently fold a different gel food color into each portion to create your rainbow layers.
Step 5: Pour each colored batter into its own prepared pan and bake at 180°C for 20–25 minutes, or until a toothpick inserted comes out clean.
Step 6: To make the frosting, beat the softened butter at high speed for 4–5 minutes until pale and fluffy. Add vanilla extract and mix well.
Step 7: Gradually add the sifted icing sugar in two parts, starting at low speed then beating at high speed until fully incorporated and fluffy. Scrape down the bowl sides as needed.
Step 8: Once the cakes are completely cool, assemble by stacking the layers in the order of violet, indigo, blue, green, yellow, and orange, spreading a layer of buttercream between each.
Step 9: Use the remaining buttercream to frost the top and sides of the cake. Garnish with rainbow sprinkles and serve.

Tips & Variations

For a dairy-free version, substitute the yogurt with a plant-based yogurt of your choice.
Use gel food colors instead of liquid to avoid thinning the batter.
Chill the frosted cake for 30 minutes before serving to help the buttercream set.

Storage

Store the cake covered in an airtight container in the refrigerator for up to 3 days. Bring to room temperature before serving for the best texture and flavor. Leftover cake can also be frozen for up to 2 weeks; thaw overnight in the fridge before enjoying.

How to Serve

A slice of six-layer rainbow cake sits on a white plate with a pink rim, placed on a white marbled surface. The cake layers from left to right are purple, dark blue, green, yellow, orange, and red, each separated by thin white cream frosting. The cake is frosted with smooth white cream on the sides and top, with colorful sprinkles decorating the right edge of the slice. Some sprinkles are scattered on the plate and surface around the cake. The texture of the cake layers looks soft and moist, and the cream appears light and fluffy.

FAQs

Can I use fresh fruit instead of food coloring?

Fresh fruit can add flavor and some color, but it won’t give the vibrant rainbow layers typical of this cake. For clear, bright colors, gel food coloring is best.
