I always make 2 batches, usually yielding 70 cookies. You can fill 35
cookies and rest you can freeze unfilled and then fill them later when
you are ready to use them.
2 tsp baking soda (10 gr)
1/4 tsp salt
1c light brown sugar (firmly packed) (220gr)
1/2c granulated sugar (100gr)
1c unsalted butter (226gr)
2 cups smooth peanut butter (535 gr)
Filled cookies will be good for about 3-4 weeks.
