The Nutter Butter is a sweet American treat to finish off a meal at Cipro Pizza a Taglio on Fountain Street in Alexandria. The oat-based cookie – which is somewhere between crisp and chewy – is filled with either a peanut butter buttercream or with a gelato, which according to co-owner and ex-Rockpool chef Catherine Adams, “takes it to another level.” She assured us that her partner eats a Nutter Butter every single day, so it must be good. We asked Adams for the recipe.
