Ingredients
Cake Layers
- 2 ½ cups (315g) all-purpose flour
- 2 ½ tsp baking powder
- 1 tsp salt
- 1 cup (200g) granulated sugar
- ½ cup (120ml) buttermilk (or substitute with ½ cup milk + 1 tsp vinegar)
- ½ cup (120ml) vegetable oil
- 4 large eggs, at room temperature
- 1 tbsp lemon zest (save an extra strip for garnish)
- ½ cup (120ml) fresh lemon juice (about 2 lemons)
Mascarpone Lemon Filling & Frosting
- 8 oz (225g) mascarpone, softened
- ¼ cup (50g) powdered sugar
- 2 tbsp fresh lemon juice
- 1 tbsp lemon zest
- ½ cup (115g) unsalted butter, softened (for optional lemon buttercream)
- 1 cup (120g) powdered sugar (for buttercream)
Step-by-Step Instructions
- Prep: Preheat oven to 350°F (175°C). Grease and flour three 6-inch round or a 9-inch square pan.
- Mix dry ingredients: In a bowl, whisk flour, baking powder, and salt. Set aside.
- Combine wet ingredients: In another bowl, whisk sugar, buttermilk, oil, eggs, lemon zest, and juice until smooth.
- Blend batter: Gradually add dry ingredients to wet ingredients. Mix until just combined (no overmixing!).
- Bake: Divide batter evenly between prepared pans. Bake 20–25 minutes, or until a toothpick inserted comes out clean.
- Make filling: Beat mascarpone, powdered sugar, lemon juice, and zest until creamy and smooth. Chill for 10 minutes.
- Assemble cake: Place one layer on a serving plate. Spread ⅓ of the filling over the top. Repeat with remaining layers and filling. For extra stability, freeze the assembled cake for 30 minutes before frosting.
- Optional frosting: Whisk butter and powdered sugar until fluffy. Add a splash of lemon juice to balance the sweetness, then spread over the cake exterior.
Tips & Variations
- Zest first, juice second: Always zest the lemon before cutting it to avoid bitter white pith.
- Mascarpone shortcuts: If unavailable, substitute with 400g cream cheese, softened, and 2 tbsp milk.
- Add color: Swirl in raspberry or strawberry jam between layers for seasonal flair.
- Gluten-free swap: Replace all-purpose flour with 1:1 gluten-free baking flour.
- Avoid cracks: Let cooled layers sit at room temperature for 15 minutes before stacking to prevent shifting.
Serving Suggestions
Serve chilled with a dollop of whipped cream and a dusting of powdered sugar. Pair with a platter of seasonal fruit or consider these options:
- Tower of lemon slices and fresh berries on top
- Side of lemon curd for dipping
- Tea or coffee for an afternoon treat
- Almond blossoms or lavender honey drizzle for a garden-themed event
Storage & Reheating
Sealed in an airtight container, this cake stays fresh in the refrigerator for 3–4 days. To reheat: microwave a slice for 10–15 seconds or warm at 300°F (150°C) for 5 minutes to restore crispiness. Note: The mascarpone filling becomes softer when warmed.
