For the Bisinger Torteletten, mix the ingredients for the cookie dough together and let rest a bit.
Then roll out the dough on the floured surface and cut out circular, small cookies. Bake in the oven until they have darkened a bit.
In the meantime, prepare the filling. For this, melt the chocolate and mix with the remaining ingredients. Once the cookies and the filling have cooled, spread all the cookies with jam on one side.
Then spread half of the cookies with the filling and press them together with the other cookie halves. Finally, sprinkle the Bisinger Torteletten with powdered sugar.
