You can make these using oats or for a Coeliac-friendly version use quinoa flakes (adding 1/4 cup extra). Use raw honey or rice malt syrup for a fructose-friendly version. Make sure to stir your natural peanut butter well before measuring as with 100% nut butters, sometimes the runnier part with all the oils sits on top. If the mixture is too soft - it will harden in the fridge, add a little extra oats / quinoa flakes. For a dairy-free version sub butter for extra coconut oil. It should be like pay-doh, not crumbly. That's it, simple.
Options: gluten-free, dairy-free, vegan, fructose-friendly.
