Why Make This High Protein Cinnamon Protein Donuts
Most traditional donuts are deep-fried and loaded with refined sugars, leading to a quick energy crash. These protein donuts are baked instead of fried, which significantly cuts down on the fat content. By using high-quality protein powder and Greek yogurt, you get a satisfying treat that keeps you full for longer.
The combination of cinnamon and a hint of vanilla creates a comforting aroma that fills your kitchen. These donuts are also incredibly versatile. You can easily adjust the sweetness or add extra toppings to suit your palate. Plus, they are kid-friendly, making them a great way to sneak some extra protein into your family’s diet.
How to Make High Protein Cinnamon Protein Donuts
Making these donuts is a straightforward process that involves mixing your dry and wet ingredients separately before combining them into a smooth batter. The key is to avoid overmixing to ensure the texture stays soft and airy.
Ingredients
- 1 cup oat flour (or blended rolled oats)
- 2 scoops vanilla whey or casein protein powder
- 1/2 cup non-fat Greek yogurt
- 1 large egg
- 1/4 cup unsweetened almond milk
- 2 tablespoons granulated stevia or monk fruit sweetener
- 1 teaspoon baking powder
- 1 tablespoon ground cinnamon
- 1 teaspoon vanilla extract
- Optional glaze: 2 tbsp powdered sweetener mixed with 1 tsp cinnamon and a splash of milk
Directions
Step 1: Preheat and Prep
Preheat your oven to 350°F (175°C). Lightly grease a non-stick donut pan with cooking spray or a small amount of coconut oil to ensure the donuts pop out easily after baking.
Step 2: Mix Dry Ingredients
In a medium-sized mixing bowl, whisk together the oat flour, protein powder, sweetener, baking powder, and ground cinnamon. Ensure there are no large clumps of protein powder for a consistent batter.
Step 3: Whisk Wet Ingredients
In a separate bowl, whisk the egg, Greek yogurt, almond milk, and vanilla extract until the mixture is smooth and well-combined.
Step 4: Combine into Batter
Pour the wet ingredients into the dry ingredients. Use a spatula to gently fold the mixture together until just combined. Be careful not to overmix, as this can make the donuts tough.
Step 5: Fill the Donut Pan
Spoon the batter into the prepared donut pan, filling each cavity about three-quarters full. You can also use a piping bag or a plastic bag with the corner cut off for a cleaner finish.
Step 6: Bake and Cool
Bake for 10 to 12 minutes, or until a toothpick inserted into a donut comes out clean. Allow the donuts to cool in the pan for 5 minutes before transferring them to a wire rack to cool completely.
Step 7: Glaze and Serve
Once cooled, whisk together the optional glaze ingredients and drizzle over the donuts. Sprinkle a little extra cinnamon on top for a beautiful presentation.
How to Serve High Protein Cinnamon Protein Donuts
These donuts are best enjoyed slightly warm. You can serve them alongside a cup of black coffee or a cold glass of almond milk. For an extra treat, serve them with a side of fresh berries or a dollop of extra Greek yogurt for a complete, balanced meal.
How to Store High Protein Cinnamon Protein Donuts
Store any leftover donuts in an airtight container. They will stay fresh at room temperature for up to 2 days, or in the refrigerator for up to 5 days. If you want to keep them longer, these donuts freeze remarkably well. Simply wrap them individually and freeze for up to 2 months. Reheat in the microwave for 15-20 seconds when ready to eat.
Expert Tips for Perfect High Protein Cinnamon Protein Donuts
To get the best results, use a protein powder that you enjoy the taste of, as it provides a lot of the flavor. If your batter seems too thick, add an extra tablespoon of almond milk. Also, make sure your Greek yogurt is at room temperature to help it incorporate better with the other ingredients.

Delicious Variations
You can easily customize this recipe! Try adding a handful of chocolate chips to the batter for Cinnamon Chocolate Chip donuts. Alternatively, swap the vanilla protein powder for pumpkin spice flavor during the fall months. For a crunchier texture, top the glaze with crushed pecans or walnuts.
Frequently Asked Questions
Q: Can I use a different type of flour?
Yes, you can use whole wheat flour or a gluten-free all-purpose blend. Note that coconut flour will require more liquid and may change the texture significantly.
Q: My donuts are dry, what went wrong?
Dry donuts are usually caused by overbaking or using too much protein powder. Check them at the 10-minute mark and ensure you are measuring your protein powder correctly.
Q: Can I make these without a donut pan?
If you don’t have a donut pan, you can use a muffin tin. They won’t have the hole in the middle, but they will still taste delicious as protein muffins!
Q: Does it matter what kind of protein powder I use?
Whey-casein blends usually bake the best. 100% whey can sometimes result in a slightly rubbery texture if overbaked, so keep a close eye on the oven.
Q: Are these donuts keto-friendly?
As written with oat flour, they are not keto. To make them keto, replace the oat flour with almond flour and ensure your protein powder and sweetener are carb-free.
