Butter Tart Squares

I am a big fan of butter tarts. There is only one problem with buying them, and that is that 99.9% of them come with raisins in them. EWWW! And I guess another problem is that they cost more money than it takes to make these great squares, and these squares taste better. :)
So try these ones and you'll fall in love. They are quick and easy and the recipe is easily doubled. I make them without nuts or raisins, then both the kids and me are happy.

Base:
1/2 Cup Butter
1 1/2 Cups Flour
2 Tbsp Icing Sugar
Cream butter and sugar, blend in flour with pastry blender. Pat into 9x9 pan. Bake at 350 for 5 minutes.

Topping:
1 1/2 Cups Brown sugar
1/4 Cup Butter, melted
2 Eggs beaten
1 Tbsp Vinegar
1 Cup Pecans/raisins/nothing :)
1 Tbsp Vanilla
Combine ingredients and pour over base. Bake at 350 for 30-40 minutes (36 min for me), until set. Butter is better than margarine in this recipe.

Thanks to Seven, I think, who gave me this recipe. Not really sure where she got it from, but it's great.
