Ananas-chocolat, simple cup cakes

Ananas-chocolat. Pineapple-chocolate. A perfect match in heaven.

For melting mini-cakes…
Roughly like the brownies :
1/2 block of tofu (200 gr) into the mortar, lots of non sweet cocoa powder, 2 tbs cane sugar, 1 tbs of instant coffee, 3 or 4 tablespoons of flour, 2 tbs of tahin (sesame butter), 2 tbs of rum, enough water to get a cream texture.
