Laurel's Fool-Proof Best Berry Pie

INGREDIENTS:
1 3/4 cups all-purpose flour
3/8 cup butter
3 teaspoons baking powder
1 teaspoon vanilla extract (or real vanilla bean)
3/8 cup white sugar
1 egg
2 1/2 cups fresh berries (more or less - I tended to just fill the pie crust until it was full!)


Crust

Blend the flour and the butter or margarine thoroughly. Add baking powder, vanilla, sugar, and egg; mix thoroughly. Let the dough rest for about 25 minutes.
Lay enough dough to cover the pie dish in the center of the pan, and spread the dough evenly over the bottom and sides of the pan. There will be dough left over for the top of the pie. Take a fork, and make holes with it here and there along the bottom of the pie dough. Let the pie dough rest again for another 25 minutes.

Before putting the berries into the crust I like to toss them with a bit of sugar if they are tart or even a bit of vanilla or if I want some extra flavor, perhaps cinnamon if I am using a dark berry like a black or blue. Put the berries into the crust and crumble remaining dough on top of fruit. After this step I like to sprinkle just a bit more sugar over the top.

Bake at 400 degrees F ( 205 degrees C) for 25 to 30 minutes.

I got this recipe online and what the site said was:
" A homemade sweet pastry dough is pressed into a pan. Then it 's filled with berries and topped with more of the crumbly dough. Bake in a hot, hot oven and enjoy this berry-good treat with generous scoops of vanilla bean ice cream."

I have tried it with raspberries, blueberries and black berries - both individually and in combination. I have a feeling that it would probably work for most fruit, though.
