Ingredients
225 gsoftened butter
225 gcaster sugar
4 pieceseggs
225 gself-raising flour
3 tablespoonsfresh lemon juice
2 pieceslemon zest
150 gicing sugar
1 teaspoonbaking powder
Instructions
1PREHEAT THE OVEN: Set your oven to 180°C (160°C fan) and line a rectangular baking tin approximately 20x30 cm with baking parchment, ensuring the paper extends slightly above the edges for easy removal. This prevents the cake edges from browning too quickly and allows for even heat distribution throughout the baking process.
2CREAM THE BUTTER AND SUGAR: In a large mixing bowl, beat the softened butter and caster sugar together using an electric mixer for approximately 3-4 minutes until the mixture becomes pale, fluffy, and noticeably lighter in color and texture. This creaming process incorporates air into the mixture, which helps create a light and airy crumb structure in the finished cake. The mixture should resemble soft whipped cream when ready.
3ADD THE EGGS AND LEMON: Add the eggs one at a time to the creamed mixture, beating well after each addition to ensure proper emulsification, which takes about 30 seconds per egg. Once all eggs are incorporated, gently fold in the lemon zest and 2 tablespoons of the lemon juice using a spatula, being careful not to deflate the mixture. The batter should remain smooth and homogeneous with visible flecks of vibrant yellow zest distributed throughout.
4FOLD IN THE DRY INGREDIENTS: Sift the self-raising flour and baking powder together into a separate bowl to remove any lumps and aerate the mixture. Gently fold the dry ingredients into the wet mixture using a large metal spoon or silicone spatula in three additions, using a cutting and folding motion rather than stirring to maintain the airiness of the batter. Continue until no streaks of flour remain visible, but avoid overmixing which would result in a dense, heavy cake.
5BAKE THE CAKE: Pour the batter evenly into the prepared tin and smooth the top with a spatula to ensure uniform baking. Place in the preheated oven for 30-35 minutes until golden brown on top and a skewer inserted into the center comes out clean or with just a few moist crumbs attached. The cake should spring back when lightly pressed and the edges should begin to pull away slightly from the tin sides.
6PREPARE THE LEMON DRIZZLE: While the cake bakes, sift the icing sugar into a medium bowl and slowly whisk in the remaining 1 tablespoon of fresh lemon juice, adding it gradually until you achieve a thick, pourable consistency that coats the back of a spoon but still flows. The glaze should be thick enough to pool on the cake surface without running off immediately, creating those characteristic crispy drizzle streaks as it sets.
7FINISH AND SET: Remove the warm cake from the oven and allow it to cool in the tin for approximately 5 minutes until it firms up slightly but remains warm. Prick the entire surface with a fine skewer or fork approximately 20-30 times, creating small channels that allow the lemon glaze to penetrate into the sponge. Immediately pour or drizzle the lemon glaze evenly over the warm cake surface, allowing it to seep into the holes and create a tangy, crispy coating on top.
8COOL COMPLETELY: Leave the cake in the tin until completely cooled to room temperature, approximately 1-2 hours, allowing the glaze to fully set and harden into a delightfully crunchy topping. Once cooled, cut into 10 squares and carefully remove from the tin using the parchment paper edges. The cake can be stored in an airtight container at room temperature for up to 3 days, though it's best enjoyed within 24 hours while the contrast between moist sponge and crispy glaze is at its peak.
