Butter Tart Squares

I made these for my cookie exchange this year! Simple and yummy! I got it out of my "Wanda's Pie in the Sky" cookbook.

Butter Tart Squares

For the crust:
1 cup cold butter cut into 1/2 inch pieces
2 cups flour
3 Tbsp. sugar

For the filling:
1 cup raisins
1 cup hot water
4 eggs
2 1/4 cup brown sugar
1/3 cup corn syrup
2 tsp. vinegar
2 tsp. vanilla extract
2 Tbsp. flour
1/2 cup butter, melted
1 cup pecans or walnuts, coarsely chopped

For the crust: Preheat oven to 350. Using a food processor or pastry blender, process or cut the butter into the flour and sugar until the mixture is mealy. Mix until it is just starting to come together and no longer looks dry. Press onto the bottom and 1 inch up the sides of a 9X13 baking pan. Bake for about 15 minutes until set and barely golden.

For the filling: Soak the raisins in the hot water for 15 minutes. Drain. Combine the eggs, sugar, syrup, vinegar, vanilla and flour in a medium bowl. Whisk until smooth. Whisk in the butter. Stir in the soaked raisins and the nuts. Pour into the baked crust. Bake for 25 to 35 minutes, or until golden and no longer liquid in the center. Cool completely before cutting into bars or squares. Store in the fridge in a tightly closed container for up to 5 days.
