Ingredients:

For the Rainbow Cake Layers:

1. 3 cups all-purpose flour
2. 3 cups granulated sugar
3. 1 cup unsalted butter, softened
4. 6 large eggs
5. 2 cups buttermilk
6. 2 teaspoons pure vanilla extract
7. 2 tablespoons baking powder
8. 1 teaspoon salt
9. Gel food coloring (red, orange, yellow, green, blue, and purple)

For the Vanilla Buttercream Frosting:

1. 2 cups unsalted butter, softened
2. 4 cups powdered sugar
3. 2 teaspoons pure vanilla extract
4. A pinch of salt

Tools:

• Six 6-inch round cake pans
• Parchment paper
• Mixing bowls
• Electric mixer
• Offset spatula
• Cake turntable (optional, but helpful)

Step-by-Step Instructions:

Step 1: Preheat and Prepare

1. Preheat your oven to 350°F (180°C). Grease six 6-inch round cake pans and line the bottoms with parchment paper.

Step 2: Mix the Dry Ingredients

1. In a mixing bowl, sift together the flour, baking powder, and salt. Set this dry mixture aside.

Step 3: Cream the Butter and Sugar

1. In another bowl, cream the softened butter and granulated sugar together until light and fluffy. This may take 2-3 minutes of mixing.

Step 4: Add Eggs and Vanilla Extract

1. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.

Step 5: Combine Wet and Dry Ingredients

1. Gradually add the dry mixture to the wet ingredients, alternating with the buttermilk, starting and ending with the dry mixture. Mix until just combined. Be careful not to overmix, as it can lead to a dense cake.

Step 6: Color the Cake Batter

1. Divide the cake batter evenly into six separate bowls.
2. Using gel food coloring, tint each bowl of batter with the colors of the rainbow: red, orange, yellow, green, blue, and purple. Start with a small amount of coloring and add more until you reach your desired vibrancy.

Step 7: Bake the Rainbow Cake Layers

1. Pour each colored batter into its own prepared cake pan.
2. Bake in the preheated oven for approximately 15-20 minutes or until a toothpick inserted into the center of the cakes comes out clean.
3. Allow the cakes to cool in the pans for about 10 minutes, then transfer them to a wire rack to cool completely.

Step 8: Make the Vanilla Buttercream Frosting

1. In a large bowl, beat the softened butter until it becomes creamy and pale in color.
2. Gradually add the powdered sugar, vanilla extract, and a pinch of salt. Beat until the frosting is smooth and fluffy.

Step 9: Assemble the Rainbow Cake

1. If needed, level the tops of the cooled cake layers with a cake leveler or a serrated knife to ensure they are even.
2. Begin with the purple cake layer as the base and spread a thin layer of buttercream frosting over the top.
3. Carefully place the blue layer on top of the purple layer and continue stacking the cakes in rainbow order, spreading a thin layer of buttercream between each layer.
4. Once all layers are stacked, apply a thin layer of frosting as a crumb coat to seal in any loose crumbs. Chill the cake in the refrigerator for about 30 minutes.
5. After the crumb coat has set, frost the cake with the remaining buttercream, creating a smooth or textured finish, depending on your preference.

Step 10: Decorate Your Rainbow Cake

Now comes the fun part! You can decorate your rainbow cake with various toppings, such as rainbow sprinkles, edible glitter, or fondant decorations. Get creative and let your imagination run wild!
