Instructions
For the dough:
Rub zest of lemon into sugar using the back of the spoon creating a lemon scented sugar.
In the bowl of your mixer, dump in flour, sugar/lemon zest mixture, butter and salt. Beat with the paddle attachment for a couple of minutes until the dough comes together in small chunks.
Press half of the dough into the bottom of a greased 9 x 9 pan. Set aside the remaining dough.
Bake the dough for 10 minutes in a preheated 350 degree oven. Let cool for 10 minutes.
For the filling:
Whisk the eggs in a large bowl. Add sugar, sour cream and flour to the eggs. Mix well and then fold blackberries.
Pour blackberries over baked crust and spread evenly.
Sprinkle the reserved dough on top of the blackberry mixture and bake for 50-60 minutes.
