Ingredients Needed
Create a vibrant Rainbow Birthday Cake with flour, sugar, eggs, butter, baking powder, food coloring, and vanilla extract. Mix and bake each colored layer separately for a stunning, colorful dessert.
Basic Ingredients
Flour, sugar, butter, eggs, and vanilla extract. These are the basics. For the frosting, you need powdered sugar, butter, and milk. Don’t forget baking powder and salt. They help the cake rise. Use fresh ingredients for best results.
Food Coloring Options
Use natural food colors or gel colors. Gel colors are more vibrant. Choose red, orange, yellow, green, blue, and purple. Mix colors to get more shades. Add a few drops at a time. Stir well to blend the color evenly. Test colors on a small piece first. Adjust as needed.
Preparing The Batter
Use room temperature ingredients for smoother batter. Beat the butter and sugar until fluffy. Add eggs one at a time. Mix well after each addition. Stir in vanilla extract for flavor. Mix dry ingredients separately. Combine flour, baking powder, and salt. Add dry ingredients to the wet mixture. Do it slowly. Alternate with milk. Mix until just combined. Do not overmix. Overmixing makes cake dense.
Divide the batter evenly. Use a kitchen scale for accuracy. Place bowls on scale. Pour equal amounts into each bowl. Color each portion with food coloring. Mix colors well. Use bright colors for a vibrant cake. Pour each colored batter into separate cake pans. Smooth the tops. Bake as instructed. Enjoy your colorful cake layers.

Creating The Rainbow Layers
Divide the cake batter into six bowls. Add a different color to each bowl. Use food coloring for bright colors. Stir until the color is even. The colors should be bold and vivid. This makes each layer stand out.
Preheat the oven to 350°F (175°C). Pour one bowl of colored batter into a cake pan. Bake for about 15 minutes. Check with a toothpick. It should come out clean. Let the layer cool. Repeat with the other colors. Stack the layers carefully. Use frosting between each layer. This keeps the cake stable.
Assembling The Cake
Place the first cake layer on your plate. Spread a thin layer of frosting on top. Make sure it’s even. Add the next cake layer. Repeat the frosting. Press down gently. Continue this process with all layers. Each layer should be even. This keeps the cake stable. Use a cake leveler if needed.
Use a crumb coat first. This is a thin layer of frosting. It traps crumbs. Chill the cake for 15 minutes. Now, apply the final layer of frosting. Use a spatula for smooth results. Work slowly and carefully. Smooth the sides and top. Make sure there are no gaps. Add decorative touches last. Enjoy your rainbow cake!
