Full disclosure: I got this idea from a website about making dog treats.
Still, it's extremely delicious!
Ingredients:
1 750g tub of plain yogurt
1 500g jar of peanut butter
1 teaspoon vanilla
Combine the vanilla, peanut butter, and yogurt in a pot and heat until peanut butter has melted and been thoroughly mixed with the yogurt.
Spoon the mixture into paper muffin cups. I filled my muffin cups about 2/3 of the way full, and managed to get 24. Freeze, and eat at your leisure. They melt in your mouth and satisfy a sweet tooth without added sugar.
I did the math to figure out the carb count, and it's a little higher than I had anticipated. I got each cup to be 10 carbs, 8 of which is from the peanut butter.
I think next time I'll make them with 2 tubs of yogurt, or maybe 1.5 tubs. They'll be less peanut-buttery, but I'll get more cups out of it and much fewer carbs per cup!
