Instructions

Preheat Oven:

• Preheat your oven to 350°F (175°C). Grease and flour six 8-inch round cake pans.

Mix Dry Ingredients:

• In a bowl, whisk together flour, baking powder, and salt.

Cream Butter and Sugar:

• In a large bowl, beat the softened butter and sugar together until light and fluffy.

Add Eggs and Vanilla:

• Add the eggs one at a time, mixing well after each addition, then stir in the vanilla extract.

Combine Mixtures:

• Gradually add the dry ingredients to the butter mixture, alternating with the milk, mixing until just combined.

Color the Batter:

• Divide the batter evenly into six bowls. Use food coloring to dye each bowl a different color.

Bake Layers:

• Pour each colored batter into the prepared cake pans. Bake for 20-25 minutes, or until a toothpick inserted in the center comes out clean.

Cool Layers:

• Allow the cakes to cool in the pans for 10 minutes before transferring to wire racks to cool completely.

Assemble the Cake:

• Once cooled, place the purple layer on a serving plate. Spread a thin layer of frosting on top, then add the blue layer, repeating the process until all layers are stacked.

Frost the Cake:

• Frost the top and sides of the cake with remaining buttercream frosting. Decorate with sprinkles, if desired.

Serve:

• Slice and enjoy the colorful layers of your vibrant rainbow cake!
