Instructions
For The Rainbow Theme Cake
- Preheat your oven to 335 °F or 168 °C and prepare your round cake pans and grease. Then, put a round parchment paper at the bottom of each pan.
- After that, combine your buttermilk with the oil in a mixing bowl and set it aside.
- In a different bowl, combine the remaining buttermilk, egg whites, and vanilla. Then, whisk to break up the eggs. After that, set it aside.
- Next, use an electric mixer attached with a paddle attachment. And combine the flour, sugar, baking powder, baking soda, and salt for ten seconds.
- Then, put the softened butter into the dry ingredients. And mix at a low speed for thirty seconds until the mixture has a coarse sand texture.
- After that, add the milk and oil mixture. Mix until the dry ingredients are moist. Then, set the speed of your mixer to medium. And mix for a full two minutes.
- Scrape the bowl using a rubber spatula. And reduce the speed to low. Next, add the egg white mixture in three batches. Then, mix the batter for 15 seconds between each addition. After that, scrape the bowl's sides to incorporate everything.
- Divide the cake batter into six bowls, about 15 ounces each bowl. Afterward, color the batter in each bowl with the color you have chosen. Remember, 1/4 tsp for pink, 1/2 tsp for yellow, and 1/4 tsp+1/2 tsp green for green. In addition to that, it is 1/2 tsp for blue and 1/4 tsp+1/2 tsp for purple.
- After that, bake your cakes for 20 to 24 minutes. Or make sure to bake until the edges start to separate from the cake pan. Because of this, do not underbake your cakes.
- Afterward, instantly tap the pan firmly on the countertop once to release the steam from the cake. Hence, this trick will stop the cake from shrinking.
- Finally, allow the cakes to cool for 10 minutes in the pan before turning it over. Make sure to chill your cakes before trimming.
For The Buttercream
- Combine powdered sugar and pasteurized egg whites in a bowl. And mix using an electric mixer attached with a whisk attachment. Mix on low speed to incorporate. And then increase the speed to high.
- After that, add the butter gradually, continue to mix until you added all the butter. Then, add in the vanilla and salt. After that, set your mixer on high until the mixture becomes light and fluffy. Afterward, add a dot of purple food coloring to cancel the yellow on the buttercream.
- Lastly, change the whisk attachment with a paddle attachment of your mixer. Doing this removes the bubbles from the buttercream; mix on low for 10 minutes.
For The Gold Drip
- Melt the chocolate in the microwave using 15-second increments. Then, add the warm milk. And microwave for another 15 seconds.
- After that, stir the mixture until smooth. Make sure to add the yellow food coloring. Then, stir again. Finally, put the ganache into a piping bag.
Notes
Essentially, place your ingredients to room temperature to ensure that the batter will not curdle and break. Also, it would help to use a scale to measure your ingredients. Because weighing your ingredients is accurate than using cups, thus giving you a better result. Furthermore, measure and weigh your ingredients ahead of time to decrease the possibility of forgetting an ingredient. In addition to that, allow your cakes to chill before stacking and frosting.
Remember, white velvet cake is best for this recipe. Also, it is very white to add the colors you want for the rainbow layers easily. Additionally, adding colors to a cake with egg yolks will change your colors while baking. Finally, keep in mind that white velvet cake will not go over mix when adding your color.
