In a large mixing bowl, use an electric mixer to cream together the softened butter and granulated sugar.
Beat the mixture until it becomes pale and fluffy, which usually takes about 3-5 minutes. This step is crucial as it helps create a fine crumb and soft texture for the cake.
Gradually add the eggs to the creamed butter and sugar, one at a time.
Mix well after each addition until fully incorporated. This ensures a smooth batter and prevents curdling.
In another bowl, whisk together the all-purpose flour, baking powder, and lemon zest.
Gently fold the dry ingredients into the wet mixture using a spatula or wooden spoon, mixing until just combined. Be careful not to overmix; this could lead to a tough cake. The batter should be smooth and creamy.
Preheat your oven to 180°C (350°F).
Grease a round or rectangular cake tin with butter or line it with parchment paper to prevent sticking.
Pour the prepared cake batter into the greased tin. Use a spatula to smooth the top evenly.
Place the tin in the preheated oven and bake for approximately 40 minutes.
To check for doneness, insert a skewer or toothpick into the center of the cake. It should come out clean or with a few moist crumbs attached.
Once baked, remove from the oven and let cool in the tin for about 10 minutes. Avoid opening the oven door too frequently while baking, as this can cause the cake to sink.
While the cake cools, prepare the lemon drizzle by juicing fresh lemons until you have about 50ml of juice.
In a bowl, combine the lemon juice and icing sugar. Stir until the mixture is smooth and runny. Adjust the sweetness by adding more icing sugar for a sweeter drizzle, or add more lemon juice for a tart flavor.
Using a skewer or toothpick, poke holes all over the top of the still-warm cake. This allows the lemon drizzle to soak in and infuse the cake with flavor and moisture.
Pour the prepared lemon drizzle over the cake, ensuring an even distribution across the surface. The aromatic drizzle will enhance the cake’s flavor and make it irresistibly moist.
Let the cake cool in the tin completely before removing it. This allows the drizzle time to seep into the cake and meld the flavors together.
Once cooled, carefully remove the cake from the tin, slice, and serve. Enjoy the refreshing burst of citrus flavor in each bite!
