Ingredients

200g gluten-free self-raising flour
150g sugar
150g butter or dairy-free spread
2 eggs or egg-free alternative
Zest of 2 lemons
Juice of 1 lemon
4 tbsp milk (any)
½ tsp baking powder

Lemon drizzle:

4 tbsp icing sugar
Juice of 1 lemon

Prepare Your Tin

Start by lining a small baking tray and preheating the oven to 180°C. Before anything else, this will save you time later and help the cake cook evenly.

Cream the Butter and Sugar

In a mixing bowl, beat the butter and sugar until pale and fluffy. It takes a minute, but once it comes together, the whole mixture looks soft and smooth.

Add the Lemon Zest and Eggs

Next, stir in the lemon zest. Meanwhile, add the eggs (or your egg-free swap) and whisk until everything is properly combined. It should look slightly looser at this point, which is exactly right.

Fold in the Dry Ingredients

Afterwards, tip in the gluten-free flour and baking powder. Fold gently rather than whisking hard, which keeps the texture lighter. Then, pour in the milk to loosen the batter just enough to spread easily.

Spread Into the Tin

Once the mix looks smooth and silky, spoon it into your lined tin. Nudge it into the corners so it sits evenly. While it stands for a moment, give your kitchen counter a quick tidy. It makes the next bit feel calmer.

Bake Until Golden

Place the tin in the oven. Eventually, after around 20–25 minutes, the top should look softly golden and bounce back slightly when touched. During this time, you can mix your lemon drizzle.

Make the Lemon Drizzle

Stir icing sugar with lemon juice until it turns glossy and pourable. It only takes a moment; however, it immediately smells amazing.

Pour the Drizzle

As soon as the cake comes out, poke tiny holes all over the top. After, pour the drizzle so it sinks into every little gap. This gives that lovely, sharp, sweet finish.

Cool and Slice

Before cutting, let the tray cool completely; it slices far more cleanly. Finally, cut into neat squares. Sometimes I add extra zest on top, but that’s completely optional.

Serve or Store

Occasionally, I microwave a square for a few seconds for an extra-soft bite. Ultimately, it stays moist for days, which is rare with gluten-free bakes. In the end, most of the tray disappears far quicker than I expected. Later, if there are leftovers, pop them in an airtight container.
Otherwise, serve straight away and enjoy the brightness. Although the recipe is simple, it feels special. Still, it comes together quickly, so it’s perfect for busy weeks.
