Remove the dough from the refrigerator and divide it into roughly equal portions. Press one half onto the bottom of the pan, then spread the quark mixture over it, smoothing the surface.

Toss the raspberries with cornstarch and distribute them evenly over the quark mixture.

Form the streusel topping with the remaining dough by pinching off small, flat pieces and distributing them over the raspberries.
