Each tier needs to be baked properly to achieve the best texture and support. Here’s how to get it right:
Preheat and Prepare – Set your oven to 350°F (175°C). Grease and line three cake pans (10-inch, 8-inch, and 6-inch) with parchment paper to prevent sticking.
Mix Dry Ingredients – In a large bowl, sift together the cake flour, baking powder (or baking soda), and salt to create a smooth, lump-free batter.
Cream Butter and Sugar – Beat unsalted butter and sugar until light and fluffy. This step is crucial for a soft, airy cake texture.
Add Eggs and Flavoring – One at a time, mix in the eggs. Then add vanilla extract, cocoa powder, or lemon zest, depending on the flavor of each tier.
Incorporate Wet and Dry Ingredients – Alternately add the dry ingredients and buttermilk (or whole milk) in three additions. Mix until just combined to avoid overworking the batter.
Bake by Tier Size – Pour the batter evenly into each pan and bake:
10-inch tier: 40-45 minutes
8-inch tier: 35-40 minutes
6-inch tier: 30-35 minutes
Check doneness with a toothpick—it should come out clean.
Cool Completely – Let cakes cool in their pans for 10 minutes, then transfer them to a wire rack for at least two hours before frosting.
