How To Make Lemon Curd Cake

Here are some quick visual instructions. Don't forget that full recipe instructions with exact ingredients can be found in the recipe card below!

To make the lemon curd, whisk the eggs with sugar, lemon juice, and zest in a saucepan. Cook over low heat, stirring constantly until it thickens—don’t let it boil.

Once thick, remove from heat and stir in the butter until smooth. Let it cool completely before using it in the cake.

Start by beating the eggs, sugar, and lemon zest together for several minutes until the mixture is pale and has doubled in volume. Meanwhile, whip the heavy cream into soft peaks using an electric mixer.

Gently fold the dry ingredients into the egg mixture, then add the whipped cream with a spatula. Mix carefully to keep the batter light and airy.

Preheat your oven to 165°C (330°F) and line three cake pans with parchment paper. Lightly grease the sides with baking spray, then divide the batter evenly between the pans.

Bake for about 40 minutes, or until a toothpick comes out clean from the center. Let the cakes cool slightly, then carefully remove them from the pans and cool completely. (Optional: trim the top crust with a knife while still warm for a smoother finish.)

Beat the butter for 5 to 7 minutes until it’s pale, fluffy, and smooth. Add the sifted powdered sugar in two parts, mixing well after each addition.

Finish by adding the vanilla extract and lemon curd, and beat again until the buttercream is light and creamy.

Place the first cake layer on a cake board set on a turntable. Pipe a ring of lemon buttercream around the edge, fill the center with mascarpone whipped cream, then add a spoonful of lemon curd on top. Repeat with the remaining layers.

Cover the whole cake with a layer of lemon buttercream, smooth it out with a spatula, and decorate as you like. Chill the cake until ready to serve.
