- Cake pan (at least a 9-inch round cake pan per layer)
- Parchment paper
- Squeeze bottles or piping bags
- Spatula
### Step-by-Step Instructions:
#### Step 1: Prepare the Cake Layers
1. **Preheat Oven**: Start by preheating your oven to 350°F (175°C).
2. **Prepare Pans**: Line six 9-inch cake pans with parchment paper and grease them lightly.
3. **Mix Dry Ingredients**: In a large mixing bowl, combine the flour and baking powder. Whisk well to ensure there are no lumps.
#### Step 2: Mix Wet Ingredients
4. **Cream Butter and Sugar**: In a separate bowl, beat together the softened butter and sugar using an electric mixer until light and fluffy.
5. **Add Eggs**: Gradually add the eggs one at a time, mixing well after each addition.
6. **Mix Dry with Wet Ingredients**: Slowly mix in half of the dry ingredients followed by some of the milk. Repeat until all ingredients are incorporated.
#### Step 3: Add Food Coloring
7. **Divide Batter**: Divide the batter into six smaller bowls.
8. **Add Food Coloring**: For each bowl, add a different food coloring (red, orange, yellow, green, blue, purple) and mix well to ensure an even color distribution.
#### Step 4: Bake Cake Layers
9. **Bake Each Layer Separately**: Pour the colored batter into prepared pans and bake for about 20-25 minutes or until a toothpick inserted in the center comes out clean.
10. **Cool Completely**: Allow each layer to cool completely on a wire rack before stacking.
#### Step 5: Assemble the Rainbow Cake
11. **Stack Layers with Frosting**: Place one colored cake layer and spread a thin layer of whipped cream or frosting between each layer as you stack them.
12. **Add Top Layer and Frosting**: Place the final colored layer on top and frost the entire cake exterior.
#### Step 6: Decorate
13. **Pipe Decorative Edges**: Use a piping bag with a small nozzle to pipe decorative edges around the cake using any remaining frosting.
14. **Serve Immediately**: Once decorated, your six-layer rainbow cake is ready to serve!
