How to Make 6 Layer Rainbow Cake Recipe with Easy Buttercream Frosting

Step 1: Prepare Wax Paper Templates

Start by preparing wax paper templates for layering.

1. Use wax paper and a pencil to trace the outline of your cake pan’s bottom.
2. Cut out 14 circles from wax paper based on your template.

Step 2: Prepare the Buttercream Frosting

Next, whip up the delicious buttercream frosting.

1. In a mixing bowl, combine all buttercream frosting ingredients until you achieve your desired consistency.
2. If too thick, add milk one tablespoon at a time until smooth.

Step 3: Stack Your Buttercream Layers

Create frozen buttercream layers to use between your cakes.

1. Spread a thin layer of buttercream on one wax paper circle.
2. Top with another circle and repeat until you have stacked multiple layers.
3. Place these in the freezer until you’re ready to assemble the cake.

Step 4: Bake the Cakes

Now it’s time to bake your colorful cakes.

1. Preheat your oven according to package directions (usually around 350 degrees).
2. Mix together the cake mix, eggs, oil, and water until well blended (about two minutes).
3. Divide the batter into separate bowls for coloring.
4. Add gel food coloring to each bowl until you reach your desired shades.
5. Pour batter into prepared pans and bake for approximately 8-12 minutes; keep an eye during baking as times may vary.

Step 5: Assemble Your Rainbow Cake

Finally, it’s time to put everything together!

2. On a serving plate or cake stand, place the first layer of cake followed by a frozen layer of buttercream frosting.

Common Mistakes to Avoid
