Mix all ingredients well except for waffles and bring to the boil, stirring constantly. Let cool down.
In the meantime, mix 250 g margarine, 250 g sugar and 15 g ground and slightly roasted coffee well. Mix everything together and coat the waffles very thinly (there are 5 in total). Now put the last base on top of the other and weigh the cake down with a flat object. I always put a tray on top and a pair of tetra packs of juice and leave it that way overnight.
Cut into cubes the next day.
You can leave it like that or sprinkle it with couverture.
Variations:
If you leave out coffee and add the following you get:
- Chocolate / cocoa filling: Coffee off, instead 30 g cocoa or
- Lemon filling: Instead of coffee, zest and juice of half a lemon
-Orange filling: instead of coffee zest and juice half an orange
This cake is very easy to make and can last a long time.
