Go Nuts for (Protein) Doughnuts

Indulge Your Cravings with this Guilt-free DIY Cake Doughnut Recipe from the INFINIT Test Kitchen

Waking up on Saturday mornings as a kid I would sprint down the stairs and begin begging my parents to take me to my favorite donut shop. 

Mom typically always held strong, insisting we had plenty to eat for breakfast at home. But my dad? He was typically persuaded a little easier. With a very spirited “please, please, pleaseeeee dad! I won't eat them in the car, I promise!”

Protein Donuts with INFINIT Repair and Raw behind it

With that we were off — It was my absolute favorite way to start the weekend. 

As a kid I LOVED donuts. Okay, who am I kidding, I still love donuts — Glazed, twisted, jelly-filled, mini, powdered, dunked or dry, I adore them all.

No matter how you like them, it’s no secret that donuts aren’t exactly considered a “health food.” These yummy pastries are typically packed with simple carbs and saturated fat, so for the average person, they’re probably best enjoyed as an occasional treat. 

Protein donuts with all ingredients needed behind them

But we’re turning that notion on its head by taking everyone’s favorite morning treat, and reworking the recipe to create a protein-packed option that can actually be used as a light breakfast or post-workout fuel.

These delicious cinnamon-sugar coated donuts don’t just have to be a treat. By incorporating protein into the mix, you can actually create a guilt free (or less) option for everyone!

Ingredients and cooking method

These cinnamon-sugar donuts provide a treat that can curb those sweet-tooth cravings without the guilt.

Baking versus frying, which is the traditional preparation method, provides a healthier option, and cuts the fat content immensely.
