Mix mascarpone, almonds and sugar with the whisk of the hand mixer until smooth. Stir in the eggs one by one. Grease 4 ovenproof moulds (approx. 150 ml each). Pour cream into the moulds and smooth down.
Bake in a preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: see manufacturer) for 20-25 minutes. Remove from the oven, sprinkle with icing sugar and serve immediately. Decorate with mint if desired.
