This plum pie is encased with a crust that's closer to the texture of a cookie than a traditional pie crust. The tangy plum filling will have you hooked!
In a large bowl, combine the butter, sugar, salt, and baking powder. Next, mix in the sour cream until well-combined.
In small portions, add the flour into the mixture until you get an elastic dough.
Split the dough into two balls (make one a bit larger than the other).
Roll out the larger piece of dough for the bottom of the pie place it in a round cake pan, lifting up the dough against the sides.
Cut the plums into halves and assemble them tightly against one another face down on top of the pie crust. Sprinkle the plums to your desire with sugar.
Roll out the second, smaller piece of dough and cover the pie with it. Using your fingers, pinch together the sides to seal the crust.
Bake at 400°F for about 25 minutes or until the crust turns golden brown.
