Tips for Making It Perfect

Use fresh lemons
Fresh lemon juice and zest provide the best flavor.

Don’t overmix the batter
Overmixing can make the cake dense.

Keep butter cold for the crumble
Cold butter creates the best crumb texture.

Let the cake cool before glazing
This keeps the glaze from melting too much.

Use parchment paper
It makes removing the cake easy.

Storage Instructions

Room Temperature

Refrigerator

Keep refrigerated for up to 5 days.

Freezing

You can freeze the cake (without glaze) for up to 2 months. Wrap tightly in plastic wrap and foil.

General Information

Crumb cakes have a long baking tradition in Europe and America. The crumb topping originated from German streusel, a buttery mixture of flour, sugar, and butter used to top cakes and pastries.

When combined with lemon cake, it creates a dessert that feels both classic and modern.

The bright citrus flavor keeps the cake refreshing rather than overly rich.
