- Why is the cream crunchy?
- Erythritol dissolves poorly in fat (mascarpone), mostly only in water. If there isn't enough water in the cream, it recrystallises. Solution: Use powdered erythritol, or dissolve in a little liquid beforehand!
- The sponge is dry.
- Wholemeal flour absorbs more liquid. Soak generously with coffee!
Sugar-Free Tiramisu Cake
The biggest challenge in sugar-free baking is not replacing sweetness, but replacing the physical properties of sugar (water binding, caramelisation, structure building). In this recipe, we use erythritol, which is chemically a sugar alcohol (polyol). Since it doesn't caramelise, the batter remains paler, and dosage must be watched as excess amounts have a cooling aftertaste and tend to crystallise in cold cream.

Instructions
1
✓
Preheat the oven to 170°C (wholemeal flour burns faster). Grease the tin. Beat the butter with half the erythritol (60g) until fluffy.
Tip: Erythritol doesn't melt like sugar, but rubbing with butter (aeration) works here too to introduce air.
2
✓
Add eggs one by one, then mix in flour and baking powder.
Tip: Wholemeal flour results in a heavier, denser batter, this is normal.
3
✓
Bake for approx. 25 minutes (skewer test). Allow to cool completely.
Tip: The sponge colour may remain paler due to lack of sugar (no Maillard reaction).
4
✓
Cream: Whip the cream. Mix the mascarpone with the remaining powdered erythritol and vanilla, then fold in the whipped cream.
Tip: Do not overmix mascarpone with a machine as fat molecules will separate and turn to butter (gritty texture). Only by hand or very slowly!
5
✓
Cut the cooled sponge in half. Drizzle the bottom layer with half the coffee.
Tip: The fibres of the cake absorb the coffee, making it moist (absorption).
6
✓
Spread half the cream, then the second layer, drizzle, and remaining cream.
Tip: Layering gives tiramisu its character.
7
✓
Dust with cocoa powder and chill for at least 3 hours.
Tip: The bitterness of cocoa powder is needed to counterpoint the sweet cream.
