Crafting Your Lemon Curd Cake: Step-by-Step Guide

Let’s build this beautiful and delicious layer cake. It’s so much easier than it looks!

1. Bake the Lemon Sponge Layers: First, preheat your oven to 180°C / 160°C Fan / Gas 4 (350°F). Butter and line the bases of three 20cm (8-inch) round sandwich tins. In a large bowl, combine the softened butter, sugar, self-raising flour, baking powder, eggs, and lemon zest. Use an electric mixer to beat everything together until you have a smooth, cohesive batter. Add just enough milk so that the mixture easily drops off a spoon.

Save

1. Cool the Cakes: Divide the batter evenly between your three prepared tins. Bake for 20-25 minutes, swapping the tins around on the oven racks halfway through so that they bake evenly. The cakes are done when they are golden and a skewer inserted into the center comes out clean. Let them cool in the tins for a few minutes before turning them out onto wire racks to cool completely.
2. Make the Lemon Buttercream: While the cakes cool, make the icing. In a large bowl, beat the very soft butter with the icing sugar, the lemon zest, and the lemon juice. Continue to beat with an electric mixer until the frosting is very light in color, wonderfully fluffy, and holds its shape.
3. Assemble Your Masterpiece: Once the cake layers are completely cool, it’s time to assemble! Place your first cake layer on a serving platter or cake stand. Spread it with a generous layer of the lemon buttercream (about one-third of the total). Then, spoon and spread a layer of lemon curd over the buttercream.

1. Layer and Decorate: Top with the second cake layer and repeat the process with another third of the buttercream and more lemon curd. Place the final cake layer on top.
2. Finish the Cake: Spread the remaining buttercream generously and artfully over the top of the cake. Decorate with your beautiful crystallized or fresh edible flowers.

Wise Tips for the Perfect Layer Cake

• Room Temperature Ingredients are Key: For the smoothest cake batter and the fluffiest buttercream, it is essential that your butter and eggs are at room temperature.
• Don’t Overbake the Sponges: The key to a moist cake is to pull it from the oven as soon as a skewer comes out clean. Overbaking will lead to a dry cake.
• Cool Cakes Completely: You must let your cake layers cool completely to room temperature before you attempt to frost them. A warm cake will melt your beautiful buttercream into a soupy mess.
• What is Self-Raising Flour? It’s simply all-purpose flour with a leavening agent (like baking powder) already mixed in. To make your own, for every 1 cup of all-purpose flour, just whisk in 1 1/2 teaspoons of baking powder and 1/4 teaspoon of salt.

Frequently Asked Questions (FAQ) – Lemon Curd Cake

Can I make this cake ahead of time?
Yes. You can bake the cake layers a day in advance, let them cool completely, and store them, well-wrapped, at room temperature. The buttercream can also be made a day ahead and stored in the fridge; just let it come to room temperature and give it a quick whip before frosting the cake.

How do I store the finished cake?
Store the finished cake in a cake carrier or covered in the refrigerator because of the lemon curd. It will keep well for up to 3 days. Let it sit at room temperature for about 30 minutes before serving for the best flavor and texture.

Where can I find edible flowers?
You can often find fresh, edible flowers in the produce section of well-stocked grocery stores, at farmers’ markets, or you can order crystallized flowers online.
