this is the recipe I was given by a friend years ago.......

1/4 tsp baking powder
1 Tblsp milk
1 egg
1 stick of softened butter
3/4 cup sugar
1 1/4 cup flour
1 1/2 tsp vanilla

Mix all together, spread in round pizza pan, bake 10 - 12 mins at 350.

BUT.....to be honest, the last few times I made this, I took the lazy way out and used a tube of that refrigerated sugar cookie dough.
