Step-by-Step Instructions

Step 1: Preheat and Prep

Preheat your oven to 350°F (175°C). Grease and line three 8-inch round cake pans with parchment paper for easy removal.

Step 2: Mix the Dry Ingredients

In a large bowl, sift together flour, baking powder, baking soda, and salt. This ensures an even, clump-free batter.

Step 3: Cream Butter and Sugar

In a stand mixer or with a hand mixer, beat the butter and sugar on medium-high speed until light and fluffy—about 3-5 minutes. This step is crucial for a tender crumb.

Step 4: Add Eggs and Vanilla

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

Step 5: Alternate Buttermilk and Dry Mix

With the mixer on low, alternate adding the flour mixture and buttermilk. Start and end with the dry ingredients. Do not overmix; just blend until incorporated.

Step 6: Bake the Cake Layers

Divide the batter evenly between the prepared pans. Smooth the tops and bake for 25–30 minutes, or until a toothpick inserted in the center comes out clean. Let cool in pans for 10 minutes, then transfer to wire racks to cool completely.

Step 7: Make the Buttercream Frosting

Beat the butter until creamy. Gradually add powdered sugar, one cup at a time. Add vanilla and enough cream to achieve a smooth, fluffy consistency. Mix in food coloring if desired.

Step 8: Assemble the Cake

Level your cake layers using a serrated knife if needed. Spread a layer of frosting between each tier. Use a crumb coat to seal the cake, then chill for 15–20 minutes. Apply a second layer of frosting and smooth it out for a polished finish.

Step 9: Decorate Creatively

Add sprinkles, piping designs, macarons, edible flowers, or glitter. Finish with a bold “16” cake topper to crown your masterpiece.
