NUGGETS OF KNOWLEDGE
Ground flax - I usually use Bob's Red Mill . I like the golden one the best! 1 flax egg=1 tablespoon ground flax and 3 tablespoon water. 
Peanut Butter - while I only tested this with creamy peanut butter, I don't see why it wouldn't be just as amazing with crunchy! If you try it this way, let me know how it turned out! I've used homemade and store bought - both have worked out well for me!
Vegan butter - I used Earth Balance in the tub while writing and testing the recipe. I usually have vegan stick butter on hand and I believe they will work great too!
Oat Milk - I would think any non-dairy milk will do, we just like the way the oat and peanut butter taste together
Bob's AP Baking flour - This time around, we are using the RED bag for this recipe. I like how the flour has a dried peanut butter vibe to it. I knew it would be perfect for these!
Dandie Marshmallows - In my opinion and testing - these marshmallows held up the best! They are GF and V, making them perfect for this recipe!
