Description

This rainbow cake rainbow is a vibrant, multi-layered vanilla cake filled with bold colors and covered in whipped frosting and sprinkles. Perfect for birthdays, celebrations, or anytime you need a dessert that makes people smile.


Ingredients

Scale

3 cups all-purpose flour

2 ½ tsp baking powder

½ tsp salt

1 cup unsalted butter, softened

2 cups granulated sugar

4 large eggs

1 tbsp vanilla extract

1 ¼ cups whole milk

Gel food coloring (red, orange, yellow, green, blue, purple)

4 cups whipped vanilla frosting

1 cup rainbow sprinkles


Instructions

1. Preheat the oven to 350°F (175°C). Grease and line six 6-inch round cake pans or bake in batches.

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

3. In a large bowl, cream butter and sugar until light and fluffy. Beat in eggs one at a time, then add vanilla.

4. Alternate adding the flour mixture and milk into the wet ingredients, mixing until just combined.

5. Divide batter evenly into six bowls. Add a different gel food coloring to each bowl and mix until vibrant.

6. Pour each color into a prepared pan and bake for 18–22 minutes, or until a toothpick comes out clean. Let cool completely.

7. Level each cake layer. Stack with whipped frosting between layers in rainbow order.

8. Frost the entire cake with remaining frosting. Decorate with rainbow sprinkles.

9. Chill for 30 minutes before slicing for best results.

Notes

Use gel food coloring to keep your batter thick and vibrant.

You can freeze baked layers for up to 1 week before assembling.

Chill the cake before cutting for cleaner slices.

For a shortcut, use a white boxed cake mix and divide into 6 layers.
