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

Step 1: Prepare Wax Paper Circles

1. The night before preparing the cakes, trace the outline of your cake pan on wax paper using a pencil.
2. Cut out 14 circular wax paper pieces based on your template.

Step 2: Make Buttercream Frosting Layers

1. In a mixing bowl, combine all buttercream frosting ingredients until smooth.
2. If too thick, add milk one tablespoon at a time until desired consistency is reached.
3. Spread a thin layer of frosting onto one wax paper circle; stack another circle on top.
4. Repeat this process with all wax circles until you have one left for the top.

Step 3: Freeze Frosting Layers

1. Place your stacked buttercream layers in the freezer until ready for assembly.

Step 4: Preheat Oven

Preheat your oven according to the instructions on the cake mix box—usually set at 350 degrees Fahrenheit.

Step 5: Mix Cake Batter

1. In a large bowl, combine both boxes of cake mix with eggs, oil, and water; blend for about two minutes.
2. Divide the batter among separate bowls based on how many colors you want.

Step 6: Color Your Batter

Add gel food coloring to each bowl gradually until you achieve your desired shades.

Step 7: Bake Cakes

1. Pour each colored batter into its own prepared pan.
2. Bake in the preheated oven for approximately 8–12 minutes; keep an eye on them as baking times may vary.

Step 8: Cool Cakes

Once baked, let cakes cool in their pans for about ten minutes before transferring them to cooling racks.

Step 9: Level Cakes (if necessary)

If needed, use a serrated knife to trim any domed tops so that layers stack evenly.

Step 10: Assemble Your Cake

On your serving platter, place one layer of cake followed by a frozen layer of buttercream frosting. Continue alternating between cake and frosting until all layers are stacked.

Step 11: Frost Your Cake

For icing:

• Using the wrong baking pans: Always ensure you use the correct size pans. Using too small or too large will affect baking time and layer structure.

• Rushing the cooling process: Allowing your cakes to cool completely is essential. Rushing this step can result in crumbling layers when stacking.
