Blueberry Cake with Crumbles and Quark

Preheat the oven to 170–175 °C and prepare a baking dish (approx. 21 cm × 21 cm).

In a large bowl, mix the flour with honey, baking powder, and room-temperature butter. The dough should have the consistency of classic crumbles. Place ¾ of the dough into the baking dish and press it down firmly with your hands.

For the quark filling, mix the quark with the eggs and grated lemon zest in a bowl. Stir the mixture until smooth and pour the cream over the dough base in the dish.
