Eggs: Room temperature eggs for better mixing and structure.
Vanilla extract: For classic flavor.
Baking powder and baking soda: Leavening agents to help the cake rise.

Step-by-Step Guide to Making a Rainbow Sprinkle Cake

1. Prepare the Cake Batter

Preheat your oven to 350°F (175°C) and grease two 9-inch round cake pans.
In a large bowl, whisk together the flour, baking powder, and salt.
In another bowl, cream together the butter and sugar until light and fluffy.
Add the eggs, one at a time, mixing well after each addition.
Stir in the vanilla extract.
Gradually add the dry ingredients to the wet mixture, alternating with the buttermilk (or sour cream).

2. Add the Sprinkles

Gently fold in the rainbow sprinkles into the batter, making sure they’re evenly distributed.

3. Bake the Cake

Divide the batter evenly between the prepared cake pans.
Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
Allow the cakes to cool in the pans for 10 minutes before transferring to a wire rack to cool completely.

4. Frost and Decorate the Cake

Once the cakes have cooled, apply a thick layer of buttercream frosting or cream cheese frosting.
Press more rainbow sprinkles onto the frosting, covering the top and sides for a beautiful, fun finish.

Creative Decoration Ideas

Decorating a rainbow sprinkle cake is where you can let your creativity shine. Here are a few ideas:

Ombre Sprinkle Design: Start with a dense layer of sprinkles at the base and gradually fade them out as you move upwards.
Polka Dot Pattern: Use sprinkles in specific colors to create fun patterns like polka dots or stripes.
Multi-Layer Surprise: Use food coloring to dye each layer of cake a different color, creating a surprise rainbow effect when you cut into the cake.

Vegan Rainbow Sprinkle Cake: Substitute dairy with plant-based milk and butter, and use flax eggs instead of regular eggs.
Gluten-Free Funfetti Cake: Swap out the all-purpose flour with a gluten-free flour blend that’s made for baking.
Low-Sugar Version: Use a sugar substitute in both the cake batter and frosting for a healthier, lower-sugar option.

Common FAQs About Rainbow Sprinkle Cakes

How do you put sprinkles on a cake without them falling off?

To get the sprinkles to stick to the sides of the cake, gently press them onto the freshly frosted surface. For the top, simply scatter them by hand. A tip is to place a baking sheet under the cake to catch any falling sprinkles for easy cleanup.

What are rainbow sprinkles made of?

Rainbow sprinkles are made from a combination of sugar, cornstarch, food coloring, and sometimes a coating of wax or glaze to give them a shiny finish. They come in various shapes, such as jimmies (long and thin) or nonpareils (tiny balls).

Can I use different types of sprinkles?

Yes! You can experiment with different types of sprinkles such as chocolate sprinkles, metallic sprinkles, or even edible glitter for a more unique look. Just keep in mind that some sprinkles may melt more easily than others during baking.

What is the flavor of a rainbow sprinkle cake?

The base flavor is typically vanilla, but you can easily change it up by adding other extracts like almond or lemon. You can even turn it into a chocolate rainbow sprinkle cake by using cocoa powder in the batter.

Storing and Serving Your Rainbow Sprinkle Cake

Storing: Once frosted, you can store your cake at room temperature for up to two days or in the fridge for up to five days. Make sure to cover it with plastic wrap to keep it fresh.
Freezing: Unfrosted cake layers can be wrapped tightly in plastic wrap and stored in the freezer for up to three months. Thaw at room temperature before frosting and serving.
Serving: For the best texture, allow the cake to come to room temperature before slicing and serving.
