Recipe

I have translated it from dutch, this is litterally all I got on the recipe
It consist of three masses made seperately and put together in the end

225gr of butter salted
225 chocolate (flates, tiny pieces really, so they melt easier) pure/milk, both work.
You just smelt this together till it is nicely done. add the butter in parts to make it easier.

3x egg yolk
4x entire eggs
beat it slightly. Not whipping, but beating, slightly

Poor mass 1 to mass two slowly. keep the spatula churning or the egg will solidify

90 gr of powdered sugar
90 gr flour (white)

Put this mixture with the rest. It is not good for refrigeration untill needed.
When needed, preheat the oven to 180 degrees celsius and bake for roughly 8 minutes.
Top must be firm, but squishy when pressed, like a spongue.
