Lemon Drizzle Cake
A simple loaf cake soaked with a hot lemon syrup that crystallises into a crunchy top.
What's going on here
This cake relies on the same principle as the lemon loaf elsewhere in this cookbook — poking holes and pouring a hot syrup over a hot cake lets capillary action pull the liquid down into the crumb, rather than letting it sit on the surface, since a hot, open crumb structure has far more capacity to absorb liquid than a cooled, set one. What's distinct here is the syrup's ratio: a high proportion of sugar to lemon juice, close to saturated, means that as the syrup's water evaporates from the surface after soaking in, the dissolved sugar has nowhere to go and recrystallises right at the top of the cake, forming a thin, crunchy, slightly frosted crust rather than staying as a sticky glaze. That crust is a textural payoff distinct from a thinner icing glaze — it depends on getting the sugar concentration high enough to crystallise as it dries, rather than staying dissolved and tacky the way a runnier glaze would.
Ingredients
Cake
- 1/2 cupButter, softened
- 1 cupGranulated sugar
- 2 tbspLemon zest
- 3Eggs
- 1 3/4 cupsAll-purpose flour
- 2 tspBaking powder
- 1/2 tspSalt
- 1/3 cupMilk
Syrup
- 1/3 cupLemon juice
- 1/2 cupGranulated sugar
a high sugar ratio, close to saturation, is what lets it recrystallise
Instructions
Prep
- Heat the oven to 175°C (350°F) and grease and line a loaf pan.
Cake
- Rub the sugar and lemon zest together with your fingertips until fragrant, then cream with the butter until pale and fluffy.
- Beat in the eggs one at a time.
- Whisk the flour, baking powder, and salt together and fold in alternately with the milk, just until combined.
Bake
- Scrape into the pan and bake until golden and a skewer comes out clean.
Syrup
- While the cake bakes, warm the lemon juice and sugar together just until the sugar dissolves — don't let it boil down further than that.
Soak
- As soon as the cake comes out, poke holes all over the top with a skewer and pour the hot syrup over slowly, letting it soak in as you go.
Tip: Both the cake and the syrup need to be hot for this to work — a cooled cake's crumb has already tightened up and can't absorb nearly as much liquid.
Cool
- Let cool completely in the pan — the crunchy top forms as the syrup's sugar recrystallises while it dries.

Tips for this recipe
Top stayed sticky, not crunchy
The syrup's sugar ratio was probably too low, or too much syrup was used. A more concentrated syrup — closer to saturated with sugar — is what recrystallises into a crisp top rather than staying as a tacky glaze.
Poke deep, generous holes
Shallow pokes only let the syrup soak into the very top layer. Push the skewer most of the way through so the syrup can reach further into the crumb.
