Marbled Cake Protein Donuts (Baked, High-Protein, No Refined Sugar)

These Marbled Cake Protein Donuts are soft, fluffy, and swirled with rich vanilla and chocolate cake, then finished with a simple white chocolate drizzle. They’re baked (not fried), naturally sweetened with honey or maple syrup, and packed with protein to keep you full longer.

Inspired by classic bakery marbled cake donuts, this healthier homemade version is perfect for busy mornings, post-workout snacks, or a better-for-you dessert that still feels like a treat.

Why You’ll Love These Protein Donuts

• High in protein from Greek yogurt and protein powder
• No refined sugar – sweetened with honey or maple syrup
• Baked, not fried for easy prep and cleanup
• Lightly sweet, not overpowering
• Freezer-friendly and great for meal prep

What Makes These Donuts Healthier?

• Greek Yogurt: Adds protein, moisture, and structure
• Applesauce: Naturally sweetens while keeping donuts soft
• Protein Powder: Boosts staying power without dryness
• Baking Instead of Frying: Less oil, less mess, same cake-like texture

Tips for Perfect Protein Donuts

• Don’t overmix the batter or the donuts may turn dense
• Fill donut molds only ¾ full to prevent overflow
• Watch closely while baking—remove as soon as a toothpick comes out clean
• Use silicone donut pans for easy release

Ingredients

  

1x2x3x

• ¾ cup all-purpose or wheat flour
• 4 scoops vanilla protein powder
• 1 teaspoon baking powder
• ¼ teaspoon baking soda
• ¼ teaspoon salt
• ½ cup unsweetened applesauce
• ½ cup plain or vanilla Greek yogurt if you want a little more sweetness, use vanilla
• ¼ cup honey or maple syrup
• 1 egg
• 1 teaspoon vanilla extract
• 4-5 tablespoons milk or buttermilk regular or plant-based
• MARBLE SWIRL
• 3 tablespoons unsweetened cocoa powder
• 3 tablespoons milk
• 1 tbsp honey or maple syrup
• 1 cup of white chocolate dark chocolate or milk chocolate chips or two squares of melting chocolate (this will dry quicker)
• 1 tsp coconut oil optional

Instructions

 

• Preheat your oven to 350°F and grease your donut pan with cooking spray. I like using silicone because the donuts pop out easier and don’t stick.
• In a large mixing bowl, whisk together the all-purpose flour, protein powder, baking powder, baking soda, and salt until well combined.
• Whisk together the applesauce, Greek yogurt, honey or maple syrup, egg, vanilla extract, and milk until smooth in a medium-sized bowl.
• Gradually add the wet ingredients to the dry ingredients, stirring until just combined. Do not overmix or your donuts will be tough.
• Take 1/4 of the batter and place in separate bowl, leaving 3/4 of the vanilla batter aside.
• In a small bowl, mix the cocoa powder, milk, and honey or maple syrup until smooth and add the mixture to the bowl with 1/4 of the batter you set aside. Make sure the chocolate is mixed in well.
• Using a pastry bag, pipe or a spoon and place the vanilla batter into the bottom and then place drop tsp of chocolate batter on top, filling each cup about 3/4 of the way up. Don't fill all the way or donuts will bake over the edge of the muffin tin.
• Use a toothpick or skewer to gently swirl the batter in each mold, creating a marble effect.
• Place the donut pans in the preheated oven and bake for 10-12 minutes, or until a toothpick inserted into the center of a donut comes out clean.
• Cool: Allow the donuts to cool in the pan for a few minutes, then transfer them to a wire rack to cool completely.
• Melt white chocolate chips in the microwave at 30-second increments until smooth, stirring in between, then drizzle over the top of each donut.
