Step-by-Step Rainbow Cake Recipe

Final Thoughts

1. Prepare & Preheat
Preheat your oven to 350°F (175°C). Grease and line two cake pans with parchment paper.

2. Mix Dry Ingredients
Whisk flour, baking powder, and salt in a bowl — this prevents lumps and ensures even texture.

3. Cream Wet Ingredients
In a large bowl, beat butter and sugar until light and fluffy. Add eggs one at a time, then stir in vanilla and buttermilk.

4. Combine & Color
Gradually mix in the dry ingredients, alternating with gel food coloring: red → orange → yellow → green → blue → purple. Use metallic or fluorescent shades for extra flair.

5. Bake
Pour batter into pans and bake 25–30 minutes. Let cool completely.

6. Frost & Decorate
Alternate rainbow buttercream layers between cakes, smoothing with an offset spatula. Top with fresh seasonal fruit, rainbow sprinkles, and edible flowers for bold visual impact.
