Homemade Rainbow Cake

I love making cake and recently I was assigned a Science project. For this project my teacher said that an Arched Rainbow Cake hadn't been made so I figured this would be my project because I love challenges and I love baking.

In this recipe I used a round 9x9 cake pan not an angel food pan.

Get all your ingredients and supplies together, this will make it a lot easier when you start.

Preheat the oven to 350 degrees. Grease a 9x9 cake pan.

My Recipe for Rainbow Cake:

1 cup Butter

1 1/2 cups Sugar

1 tablespoon Vanilla extract

1 tablespoon Lemon juice

6 Eggs

1 cup Mayonnaise

2 cups flour

1 teaspoon Baking Powder

1 1/2 teaspoons Salt

3 Egg Whites

Instructions are as steps.

My Icing Recipe:

1 pound Powdered Sugar

1/4 cup Butter

3/4 cup Sour Cream

1 tablespoon Lemon Juice

1 tablespoon Corn Syrup

Directions are as steps

Beat together Sugar, flour baking powder, salt, mayonnaise, eggs.

Separate the batter into four different bowls then dye four of them in the following order, red, green, blue, yellow.

Put each color into a different 9x9 greased round cake pan.

Bake the cake at 350 for 15-20 minutes.

Whip all the ingredients together and ice the cake then freeze for 45 minutes before cutting shape like rainbow and icing again.

This is my final product:
