Why Make This High Protein Apple Cinnamon Protein Donuts
Most donuts are loaded with refined sugars and unhealthy fats that leave you feeling sluggish. These protein donuts flip the script by using oat flour and high-quality protein powder to provide sustained energy. The addition of fresh apples adds natural sweetness and fiber, making them incredibly moist without the need for excessive oil. They are incredibly easy to meal prep on a Sunday, ensuring you have a healthy, delicious treat ready for the entire week. Plus, they satisfy that seasonal craving for apple cider donuts in a way that actually fuels your body.
Ingredients
- 1 cup Oat flour (blended rolled oats)
- 2 scoops (approx. 60g) Vanilla protein powder (whey or whey/casein blend works best)
- 1 tsp Baking powder
- 1 tsp Ground cinnamon
- 1/4 tsp Ground nutmeg
- 1/4 tsp Salt
- 1/2 cup Unsweetened applesauce
- 1/4 cup Liquid egg whites
- 1/4 cup Unsweetened almond milk
- 1/2 cup Finely diced apples (peeled)
- 1 tsp Vanilla extract
- Optional: Stevia or monk fruit sweetener to taste
Directions
Step 1: Preparation
Preheat your oven to 350°F (175°C). Generously grease a non-stick donut pan with coconut oil spray or a light coating of butter. Set the pan aside while you prepare the batter to ensure the donuts don’t stick after baking.
Step 2: Mix Dry Ingredients
In a large mixing bowl, whisk together the oat flour, vanilla protein powder, baking powder, cinnamon, nutmeg, and salt. Ensure there are no large clumps of protein powder so the texture remains smooth and consistent throughout the donut.
Step 3: Combine Wet Ingredients
In a separate medium bowl, stir together the unsweetened applesauce, liquid egg whites, almond milk, and vanilla extract. If you prefer a sweeter donut, add a tablespoon of your favorite calorie-free sweetener here and whisk until well combined.
Step 4: Fold and Fill
Slowly pour the wet ingredients into the dry ingredients. Stir gently with a spatula until just combined; do not overmix, as this can make the donuts tough. Fold in the finely diced apples. Transfer the batter into a piping bag or a plastic bag with the corner snipped off, and fill each donut cavity about 3/4 of the way full.
Step 5: Bake and Cool
Place the pan in the center rack of the oven and bake for 10 to 12 minutes, or until the donuts are springy to the touch and a toothpick comes out clean. Remove from the oven and let them cool in the pan for 5 minutes before transferring them to a wire rack to cool completely. For an extra touch, dust with a little extra cinnamon or a light protein glaze.
Expert Tips for Perfect High Protein Apple Cinnamon Protein Donuts
To get the best results, use a whey-casein protein blend. Casein helps the donuts retain moisture and prevents them from becoming rubbery. If you only have whey, be careful not to overbake them. Make sure to dice your apples very finely; large chunks may cause the donuts to break apart when you remove them from the pan. Finally, if you don’t have oat flour, simply pulse old-fashioned oats in a blender until they reach a fine, flour-like consistency.
Delicious Variations
You can easily customize these donuts to suit your cravings. For a “Crunchy Apple” version, add two tablespoons of chopped walnuts or pecans to the batter. If you want a more decadent treat, create a simple glaze using a small amount of powdered monk fruit sweetener mixed with a splash of almond milk and drizzle it over the cooled donuts. You can also swap the cinnamon for pumpkin pie spice for a different seasonal twist.

Frequently Asked Questions
Can I use a different type of flour?
Yes, you can use whole wheat pastry flour or an all-purpose gluten-free flour blend. However, oat flour provides the best texture and nutritional profile for this specific recipe.
How should I store these protein donuts?
Store them in an airtight container in the refrigerator for up to 5 days. Because they contain fresh fruit and applesauce, they stay moist longer when chilled.
Can I freeze these for later?
Absolutely! Wrap each donut individually in plastic wrap and store them in a freezer-safe bag for up to 3 months. Thaw them overnight in the fridge or pop them in the microwave for 15 seconds to enjoy warm.
What protein powder flavor is best?
Vanilla is the most versatile and complements the apple and cinnamon perfectly. Salted caramel or cinnamon bun flavored protein powders also work exceptionally well in this recipe.
Why did my donuts turn out dry?
Dryness is usually caused by overbaking or using a pure whey isolate protein powder without enough moisture. Ensure you measure your applesauce accurately and start checking the donuts for doneness at the 10-minute mark.

These High Protein Apple Cinnamon Protein Donuts are the ultimate way to enjoy the flavors of fall while staying on track with your nutritional goals.
