Step-by-Step Lemon Crumble Cake Recipe
Follow these detailed instructions for perfect results.
Step 1: Prepare the Lemon Milk
Pour the milk into a saucepan and add the lemon zest.
Warm the mixture over low heat while stirring occasionally. Do not allow the milk to boil. Heating the zest in the milk helps release essential oils and creates a deeper lemon flavor.
Once the milk is hot and fragrant, remove it from the heat.
Step 2: Make the Custard Filling
In another saucepan, whisk together:
- Eggs
- Sugar
- Flour
Continue whisking until smooth and lump-free.
Slowly pour the warm lemon milk into the egg mixture while whisking continuously. This gradual process prevents the eggs from scrambling.
After combining everything, place the saucepan over medium-low heat.
Cook while stirring constantly until the mixture thickens into a smooth custard.
Once thickened, remove from heat and stir in the lemon juice.
Allow the cream to cool slightly.
Step 3: Prepare the Crumble Dough
In a large mixing bowl, combine:
- Flour
- Sugar
- Baking powder
Add the eggs and soft butter.
Use your hands or a fork to mix until a crumbly dough forms.
The texture should resemble coarse crumbs rather than smooth cookie dough.
Avoid overmixing.
Step 4: Assemble the Cake
Line your cake pan with parchment paper.
Press half of the crumble mixture into the bottom of the pan to form the crust.
Do not press too hard.
Pour the lemon cream filling over the crust and spread evenly.
Keep the filling slightly away from the edges.
Sprinkle the remaining crumble mixture over the top without compacting it.
This creates the signature crunchy topping.
Step 5: Bake
Preheat your oven to 180°C (350°F).
Bake the cake for approximately 45 minutes or until:
- The top becomes golden brown
- The filling is set
- The edges are lightly crisp
Allow the cake to cool completely before slicing.
For the best texture, refrigerate for at least 1 hour before serving.
Tips for the Perfect Lemon Crumble Cake
Small details can make a huge difference when baking.
Use Fresh Lemons

Do Not Overcook the Custard
