It's about time I made some!
But I thought I'd try them in a square.
1 lb pie dough
4 eggs, beaten
2 cups brown sugar
1/4 cup melted butter
1/4 cup flour
1 tsp baking powder
2 tsps vanilla
2 cups raisins
Roll out the dough, and let it rest 5 minutes, then check for size. You want it to be a 10 X 13" rectangle for an 8 X 11" baking dish. Place it in the dish, press up the sides and flute the edges.
Put it in the fridge for 10 - 15 minutes.
Prick it with a fork several times and bake in a 350F oven for 10 minutes.
I forgot to put mine in the fridge so the sides shrunk a bit : (
For the filling simply combine all the ingredients and pour into the pre-baked shell.
Bake at 350 F for 30 minutes. Cool completely before cutting.
Because my dough had shrunk I had filling leftover so I did end up making a few mini tarts too. Bake them 15-20 minutes.
