Cut together with knives (I use my Bosch):
5 C. flour
1 tsp. salt
1 C. butter
1 1/2 C. sugar
1 tsp. baking powder
Make a well in the center and add:
1 C. sour cream, to which 1 tsp. baking soda has been added
2 beaten eggs
1 1/2 tsp. vanilla
Mix. Refrigerate a little before rolling out and cutting.
Bake at 425° for 4-6 min. Do not let edges get brown.
If you are using jello, you might want to cover your pan with aluminum foil. If not, it washes.
