Set your oven to 165°C (325°F) and line three 15 cm (6-inch) tins with baking paper. Combine plain flour, baking powder, fine salt, baking soda, and cornflour in one bowl. In another, using a mixer set on medium, whip softened butter with icing sugar and lemon zest until fluffy. Blend eggs and vanilla into this mix until smooth, then carefully alternate adding the dry mix with buttermilk and lemon juice until it’s lump-free.

Divide the mix equally into the tins, smoothing the tops. Bake for about 30 minutes or until they’re lightly browned and a toothpick comes out clean. After a few minutes of cooling in the tins, move the layers onto a rack to cool completely.

Trim your cake layers if necessary. Start with one layer on a cake stand, pipe a circle of strawberry buttercream around the edge, and spread strawberry compote and whipped mascarpone in the middle. Layer the next cake and repeat until all layers are stacked. Cover the whole thing in a thin coat of buttercream, then refrigerate for 2 hours or quick-freeze for 30 minutes.

Over a bowl of simmering water, gently melt white chocolate and cream together. Stir in lemon curd and a drop of yellow color, cooling the glaze to about 30°C (86°F). Pour it on top of the chilled cake, letting it run down the edges for a drip effect. Finish decorating with buttercream swirls and slices of lemon. Let the cake sit for 20–30 minutes at room temperature before serving.
