Double Tiramisu with Vanilla Bean

Method

1. Heat the oven and prepare your pan; measure unsalted butter and lemon precisely.

2. Combine the dry and wet ingredients just until smooth, without overmixing.

3. Fold in mascarpone and transfer the batter to the pan, leveling the top.

4. Bake until set and golden and a tester comes out clean.

5. Cool before slicing so the tiramisu holds its shape.
