Rainbow Swirl Cake

A child’s birthday is a big day, particularly for kids between one and five years of age. It’s the ideal time to ornament something beautiful. Therefore, if you wish to create something beautiful and artistic, there can’t be anything better than a rainbow swirl cake.

Many other cakes, like the smash cake, are for 1-year-old babies. However, for other children, I recommend that you try something artistic.

Rainbow Swirl Cake Recipe

Preparing the Pans

First, get two 9-inch round cake pan. One 9 x 13-inch baking dish ready. Once the pans are greased with butter, they should be dusted with flour. You can use parchment paper if you want even more protection against sticking. 

As for the sides, make strips; for the bottom part, cut rounds to match the pan bottoms, though the strips should be a couple of inches higher than the pan edges with the paper. 

Make sure you grease the parchment paper slightly using cooking spray.

Making the Batter

1. Creaming Butter and Sugar

First, cream loose butter and white sugar in a large mixing bowl. Next, use the mixer to whisk the mixture until it becomes light and fluffy. In the case of hand blending, you need to expect a longer time to blend and knead the ingredients together.

2. Incorporating Eggs

Now mix one egg at a time into the mixture; ensure that you wash you whisk or spatula after each addition. Take care that one combination creates an even mixture with the other before adding the next mixture.

3. Creating a Cream Cheese Mixture

Combine softened cream cheese with white chocolate chips and Greek yogurt, and sprinkle with salt. Microwave for another minute before letting it stand. Stir until smooth, adding more 30-second heating bursts if needed.

4. Combining Mixtures

Combine the cream cheese mixture with the butter and sugar mixture. Mix them together until you get a smooth texture.

5. Final Batter Preparation

After this, you need to add your vanilla extract & baking powder. Slowly add the cake flour to your mixture, stirring it thoroughly after each cup. This will help you achieve a smooth batter without any lumps.

Dividing and Coloring the Batter

Separating the Batter

After this, the batter needs to be divided into 5 separate bowls. Here, I use a slightly different method. First, I divide the batter into 2 large bowls and then into 3 smaller bowls.

Adding Jell-O Flavors

Add Jell-O powders to each bowl:

• Raspberry (red): 2 tablespoons
• Orange (yellow): 2 tablespoons
• Lemon (yellow): 2 tablespoons
• Lime (green): 3 tablespoons
• Berry Blue (blue): 2 tablespoons
• Grape (purple): 2 tablespoons

Stir every bowl to make sure even flavor & coloration.

Assembling the Cake

Layering Colours

Make tiny batter puddles in the first pan:

1. Raspberry (red)
2. Orange (yellow)
3. Lemon (yellow)

The second pan’s layer is:

1. Lime (green)
2. Berry Blue (blue)
3. Grape (purple)

Creating the Swirl

With the butter knife, gently swirl around in the saucepan. Create a swirl by drawing from the pan’s edge toward its center. To maintain good color separation, do not overmix colors.

Baking

Baking Instructions

Preheat the oven to 325°F. Bake for 20-25 minutes. Use a toothpick placed multiple times in the middle area to check if it emerges clean for doneness testing. The outer surfaces of the cakes will show golden brown tones when ready.

Cooling

Let the cakes cool in the pans for about 20 minutes. Use a knife to loosen the edges before turning it upside down to cool on a rack until cool completely.

Finishing Touches

Frosting

Finally, when the cake is cold, frost it with your desired frosting. Do some additional preparation if necessary, then dress up the plates and serve.

Tips for the Best Rainbow Swirl Cake

1. Use Gel Food Coloring

Use food coloring paste or gel rather than liquid dyes. These are used in smaller quantities and provide more vibrant colors. This way, the cake’s texture remains intact, and you achieve the proper colors.

2. Mix butter and sugar properly

Beat the butter and sugar well. Achieving a nice fluffy and creamy texture takes about 4 to 5 minutes. This results in a very soft and light cake.

3. Make a thick batter

Make sure your batter is not too thin; if the batter is thin, the colors will mix during baking. So, for best appearance, pay attention to consistency.

4. Divide Batter Evenly

To ensure your cake looks great when you slice it, measure your batter using a kitchen scale so each color has the same amount. It maintains the layer’s uniform thickness and helps them bake evenly.

5. Swirling Technique

When putting the different colored batters into the baking pan, pour them into the middle, alternating the colors as you go. If you want, you can use a skewer or a knife to mix the colors gently, but be careful not to mix them too much, or you’ll lose the pretty color patterns.
