    There's nothing quite like a cinnamon sugar cake donut for breakfast, and with this healthier version, you'll want to eat them every day! These baked cinnamon sugar donuts with protein use erythritol in place of sugar for a better-for-you donut. They make a great high protein breakfast or snack!

    Important note: I originally made these donuts with a whey protein that is now discontinued, and I haven't quite found another protein shake powder that bakes as well. So I've updated the recipe to use Proteinfull Baking cake mix, which has the absolute best protein cake taste and texture you'll find!

    Once you try the cake mix, I know you'll be hooked. So check out these other recipes using Proteinfull Baking cake mix: 🍩 glazed baked donuts, 🍌 banana walnut cake, 🍋 lemon bundt cake, and blueberry muffins with crumb topping 😍.

    Full disclosure- I developed the recipes for Proteinfull Baking mixes. By far the best protein cake, and the best keto-friendly cake I've created or tasted. The texture is super soft and moist!

    🍫 Ingredients

    For the cake donut:

    • Proteinfull Baking cake mix
    • eggs
    • oil or unsweetened applesauce
    • water
    • nutmeg
    • ground cinnamon

    For the cinnamon sugar coating:

    • coconut oil
    • granulated erythritol
    • ground cinnamon

    👩🏼‍🍳 Instructions

    Preheat your oven to 325F (160C). (Use an oven thermometer for best results.)

    Combine cake mixe with eggs, oil (or applesauce), and water. Mix just until no lumps remain.

    Pour or pipe the batter into the donut pan.

    Bake for 14-16 minutes.

    Mix erythritol and cinnamon in a bowl.

    Brush each donut with melted coconut oil (to make the coating stick), and dip into the coating.

    Enjoy! Donuts can stay out for the day, but refrigerate for longer storage.

    🍫 Substitutions

    There is nothing like Proteinfull Baking mix, so I can't recommend any subs for that.

    Other granulated sweeteners (ex. monk fruit erythritol blend) would also work for the coating.

    🥣 Equipment

    You'll need a donut pan, here are my favorite non-stick metal donut pan and silicone donut pan.

    For piping the batter, these are my favorite piping bags. They are made of a smooth plastic that doesn't stick to itself or to your bowl scraper as you push the batter down the bag.

    You'll need a bowl to mix the batter, of course. If you're looking for nice mixing bowls, I love this set of 3 mixing bowls. They have a non-slip base and are easy to clean.

    🥶 Storage

    These donuts can stay out for the day, but I suggest refrigerating for longer storage (up to a week).

      Hi Jayne,
      Different whey protein protein powders may need different amounts of liquid, so it is possible the protein you are using needs a bit more liquid. You can add water or milk or more applesauce. But as long as you are using whey, you won't need eggs. Hope that helps!

      I put the ingredients together and 2/3 cup applesauce is not enough moisture. The donut mix is still powered. Should there be egg and/or other liquids??
