Reese's Pieces Protein Donuts

It's been a little while since i've posted a donut recipe but I promise you this one was worth the wait!
Peanut butter lovers everywhere, I bring you - Reece's Pieces Protein Donuts! The best bit is they're only 44 calories each. They're also gluten free.
I made mine using a donut maker but if you don't have one you can use a regular donut mould in the oven. If you're a big donut fan it is definitely worth investing in a donut maker though as in my opinion it really does make a huge difference to the end result! You can get a great one here.
