How to store these cookies: Unfrosted cookies (preferred storage method) can be stored for up to three days at room temperature in an airtight container.
Frosted cookies can be stored in fridge for up to three days. They do not stack (the frosting is too soft) so it’s easiest to store them unfrosted. If stored with the cereal topping the topping won’t stay crisp (it’ll become soft and chewy from the frosting).
Freeze unfrosted cookies for up to 4-6 weeks.
Frosting Notes: Can be made ahead up to a few days in advance and warmed in the microwave before topping the cookies. Recipe for frosting makes about 3/4 cup.
Cookie size: I opted to make these cookies a little smaller than the Crumbl original. Rather than 4-4.5″ inches, these cookies are about 3″.
