Blueberry Crumble Donuts

Jump to Recipe

I haven’t made a donuts in a hot second so I decided I would change that with these blueberry donuts that have the TASTIEST crumble topping. I wanted to make a simple recipe that didn’t have a whole lot of added sugar (just the topping!!) and were also packed with some healthy fats with plenty of protein.

Not to pat myself on the back but I’m pretty sure I nailed this recipe!!

I used Buckwheat flour – one of my favorite gluten-free flours that is really underrated (imo) along side Nuzest to amp up the protein without sacrificing texture. I’m all about the gluten-filled and sugary donuts (seriously, COME AT ME with those beauties. Maple is my fave mmk?). However, when I’m looking for a snack that is going to keep my mind and body running at tip top shape, having protein included in the snack is a MUST.
