1 stick of unsalted, softened butter
1/2 cup of sugar
1 tablespoon of vegetable oil
1 egg, well-beaten
2 teaspoons vanilla extract
2 cups of flour
2 teaspoons baking powder
pinch of salt
1 jar of Carol Hall's Jam (any flavor)
In a large bowl, cream butter, sugar and oil. Add egg and vanilla.
In separate bowl, mix dry ingredients, whip together to aerate.
Now add egg mixture and mix well - until dough begins to form a ball - should be quite firm.
Wrap in wax paper and freeze for about half an hour or chill for one hour.
Preheat over to 350* and grease a 10x7 pan.
Press one half of the mixture of dough evenly on bottom of pan. Spread jam over the top.
Grate remaining dough evenly over the top of the jam.
