I can help you with the Rainbow Cake recipe! This is a layered colored cake that represents the colors of the rainbow. It’s somewhat laborious, but the end result is often astonishing and festive. Here is the recipe!

Ingredients

• 300 g of all-purpose flour
• 300 g of granulated sugar
• 5 large eggs at room temperature
• 250 g of unsalted butter, softened
• 250 ml of whole milk at room temperature
• 1 tablespoon of vanilla extract
• 3 teaspoons of baking powder
• 1 pinch of salt
• Gel food coloring (red, orange, yellow, green, blue, violet)

For the buttercream:

• 300 g of unsalted butter, softened
• 600 g of powdered sugar
• 2-3 tablespoons of whole milk
• 1 teaspoon of vanilla extract

Preparation

1. Preheat the oven to 180 °C and prepare six 15-20 cm diameter round pans by greasing and flouring them, or lining them with parchment paper.
2. In a large bowl, beat the butter with sugar until light and fluffy. Add the eggs one at a time, mixing well after each addition.
3. Add the vanilla extract and mix well.
4. In a separate bowl, sift together the flour, baking powder, and salt.
5. Add the dry ingredients to the butter mixture, alternating with the milk, beginning and ending with the dry ingredients. Mix until no lumps are visible.
6. Divide the batter into six equal parts and color each one with gel food coloring, one for each color of the rainbow.
7. Pour the batters into the prepared pans and level the surface.
8. Bake in the oven for 15-20 minutes or until a toothpick inserted in the center of each cake comes out clean.
9. Allow the cakes to cool in the pans for about 10 minutes, then transfer them to a wire rack to cool completely before decorating.

For the buttercream:

1. Beat the butter until creamy.
2. Gradually add the powdered sugar alternating with milk and vanilla extract, until a spreadable and fluffy consistency is achieved.

Assembly:

1. Level the cakes if necessary by slicing the top off.
2. Start with the first layer of cake and spread an even layer of buttercream on top.
3. Continue layering the remaining colors of the cake, spreading the cream between each layer.
4. Once all the layers are stacked, cover the entire cake with a thin layer of buttercream to seal in the crumbs.
5. Place the Rainbow Cake in the refrigerator for at least 30 minutes.
6. Afterward, apply a second layer of buttercream to achieve a smooth and clean finish.

The Rainbow Cake is often used to celebrate special occasions and also to show support for LGBT pride. The combination of different colors requires time and precision, but it displays a true wow-factor when cut in front of guests.

Remember that for the best results, you should use gel colors which are more concentrated and give more vibrant colors compared to liquid ones. Have fun and happy cooking!
