I have a chocolate peanut butter cup recipe that I use almost weekly, and I would like to make a large batch of the filling. It is butter, graham cracker crumbs, powdered sugar, and peanut butter. On their own, the ingredients won't go bad for months (years?), however, how long will they keep when blended together and put in the fridge? Freezer?
(Oh, and $10 off your order of $50 or more in the Food52 Shop, too.)
