1. Blue Birthday Cake Recipe

A Blue Birthday Cake is a soft vanilla layer cake covered with fluffy blue buttercream, making it a simple centerpiece for a boy’s first birthday party. The vanilla cake keeps the flavor familiar, while the blue frosting gives the dessert that classic first-birthday look.

Ingredients

For the Vanilla Cake

• 2 cups all-purpose flour
• 2 teaspoons baking powder
• ½ teaspoon salt
• ¾ cup unsalted butter, softened
• 1 ¼ cups granulated sugar
• 3 large eggs
• 2 teaspoons vanilla extract
• ¾ cup whole milk

For the Blue Buttercream

• 1 cup unsalted butter, softened
• 4 cups powdered sugar
• 2 teaspoons vanilla extract
• 3–4 tablespoons milk

Instructions

1. Prepare the pans. Heat the oven to 350°F (175°C). Grease and line two 8-inch round cake pans with parchment paper.
2. Mix the dry ingredients. Whisk together the flour, baking powder, and salt.
3. Cream the butter and sugar. Beat the softened butter and sugar until light and fluffy.

6. Bake. Divide the batter between the pans and bake for 25–30 minutes, or until a toothpick inserted in the center comes out clean.
7. Cool completely. Let the cakes cool in the pans for about 10 minutes before transferring them to a rack.

Easy Tips for a First Birthday Dessert Table

A first birthday party can get busy quickly, so desserts that can be prepared ahead of time are especially helpful.

• Bake cakes a day ahead. Completely cooled cake layers are easier to frost and decorate.
• Keep decorations simple. Sprinkles, buttercream, and a few edible decorations can create a beautiful party look.
• Mix large and small desserts. A main birthday cake paired with cupcakes and cookies gives guests plenty of choices.
• Use one color palette. Blue, white, silver, and a small amount of another accent color can tie the dessert table together.
• Make cookies ahead. Decorated sugar cookies are convenient because they store well.
• Keep the smash cake simple. A small soft cake with a smooth layer of frosting is plenty for a first birthday cake smash.
• Think about serving size. A large centerpiece cake doesn’t have to be the only dessert. Cupcakes and cookies can help serve a crowd.
