Chop the chocolate. Mix all ingredients, except for the couverture and fat, and leave to steep in the refrigerator overnight.
Cover a baking sheet with parchment paper, then line with the wafers. The edges can be glued together well with a little water, so that a large wafer plate is created.
Then distribute the dough mass evenly over the wafers (moisten your hands if necessary). Bake at 175 ° C top / bottom heat (150 ° C convection) for about 30-35 minutes. Let cool down.
Then melt the couverture and coconut fat (water bath!) And distribute evenly over the brownies. Let cool and cut into small rectangles.
