1. Place half of the sponge fingers into the bottom of a deep sided serving dish

2. In a small bowl, mix the coffee powder with 2 tablespoons of hot water, then stir in the Tia Maria and 1 tbsp of sugar and drizzle half of this all over the sponge and set aside.

3. Put the quark, sugar and vanilla extract in a large bowl and mix together with an electric whisk until light and fluffy. Spoon half over the sponge, leveling the surface.

4. Arrange the remaining sponge on top and drizzle with the remaining coffee mixture. Top with the remaining quark mixture and chill for at least 2 hours, or overnight.

5. Use a small sieve to lightly dust cocoa powder over the tiramisu and serve.

Chef tip

If you don’t have tia maria you can also use brandy for this recipe, or for an even healthier version leave out the alcohol.
Try adding a few drops of almond essence instead of vanilla extract and sprinkle the tiramisu with some toasted almonds for a delicious alternative
