You can use different types of crackers, as it's only a way to hold the peanut butter and bud mix (which is the important mixture in the recipe).
The one thing that should not be substituted is the type of peanut butter.
I have found that it is best to use use "Natural Peanut Butter", not Skippy or any of the brand names.
These brands process out allot of the peanut oil which seems to be the key ingredient that helps to release the THC in the cannabis when getting heated in the oven, so natural peanut butter is ideal.
