Recipe Instructions

Step 1: Prepare the Dry Ingredients

In a medium bowl, whisk together 2½ cups all-purpose flour, 2½ teaspoons baking powder, and ½ teaspoon salt until evenly combined.

Step 2: Cream the Butter and Sugar

In a large bowl, beat 1 cup softened unsalted butter and 1¾ cups granulated sugar for 3 to 4 minutes until light and fluffy.

Step 3: Add Eggs and Flavorings

Beat in 4 large eggs one at a time. Mix in 2 tablespoons freshly grated lemon zest, ¼ cup fresh lemon juice, and 1 teaspoon vanilla extract.

Step 4: Finish the Batter

Add the dry ingredients from Step 1 and 1 cup whole milk, alternating between them. Mix just until combined.

Step 5: Fill the Cake Pans

Divide the batter evenly between three greased 8-inch cake pans.

Step 6: Bake the Cake Layers

Bake at 350°F (175°C) for 25 to 28 minutes until the tops are lightly golden and a toothpick comes out clean.

Step 7: Cool the Cakes

Let the cake layers cool in the pans for 10 minutes, then transfer to a cooling rack and cool completely.

Step 8: Make the Chantilly Cream Frosting

Beat 16 ounces softened mascarpone cheese, 2 cups cold heavy whipping cream, 1 cup powdered sugar, 1 teaspoon vanilla extract, and 1 tablespoon fresh lemon juice until thick and fluffy.

Step 9: Assemble the Cake

Place one cooled cake layer on a cake stand. Spread frosting on top. Repeat with remaining layers.

Step 10: Frost and Garnish

Cover the entire cake with the remaining frosting. Decorate with thin lemon slices and 1 teaspoon lemon zest.

Why This Recipe Works (Quick Science)

• Butter traps tiny air bubbles during creaming, helping create a lighter cake.
• Baking powder releases gas while baking, making the layers rise.
• Lemon juice adds flavor while balancing sweetness.
• Mascarpone stabilizes the whipped cream frosting.
• Whole milk adds moisture and softness.

Common Mistakes

• Overmixing the batter can make the cake dense.
• Frosting a warm cake can cause melting.
• Using cold butter prevents proper creaming.
• Adding all dry ingredients at once can create lumps.
• Overwhipping the frosting can make it grainy.

What to Serve With

• Fresh berries
• Hot tea
• Coffee
• Vanilla ice cream
• Lemon curd on the side
• Sparkling lemonade
