    The only problem I have with these is not eating them all at once! I used a food processor to mix the oat mixture so the oats were chopped up pretty thoroughly. I added a scoop of chocolate collagen protein powder to the oat and peanut butter mixture in addition to the vanilla protein. These are really good. Even my husband said they remind him of a Reese’s peanut butter cup, which coming from him is a huge compliment. I already have to hide the peanut butter from him so he doesn’t polish off the whole jar in a few days, so this treat is perfect for any peanut butter/chocolate lover!
