"It's incredibly easy and works with a lot of nut butters! It can be multiplied for any amount. I've made up to 6x before. :-)"
"Note: I also make a thumbprint version of this called Peanut Butter and Jelly. Just use the tip of a wooden spoon to make a small well in the center and fill with 1/2tsp of any jam you like!)"
