Not kidding, I was SO scared to try this protein bundt cake recipe after hearing so much about how the cake just sticks to the pan, but I actually got it right on the first try!
Did take some pointers on how to do this online though. So credit goes there. I put some notes below.

As for the actual recipe though? It's super easy too and all clean ingredients!

Ingredients for Chocolate Protein Bundt Cake

This chocolate protein bundt cake recipe is made simple and healthy ingredients and 3 sources of chocolate - the protein powder, cocoa powder and chocolate syrup too!

  • Whole Wheat Pastry Flour
    To sub: Use All purpose flour or 1:1 Gluten Free Baking Flour in the same amount by weight, not cups.
  • Whey-Casein Chocolate Protein Powder needed for a high protein chocolate cake and also replace most of the sugar.
    I used Whey-Casein Chocolate protein powder from Quest Nutrition.
  • Whey Chocolate Protein Powder: Dymatize ISO 100 Chocolate Whey.
  • Unflavored Whey Protein Powder like this one from KOS
    Sub: ⅓ cup flour, but also reduce Yogurt to ½ cup
  • Unsweetened Cocoa Powder 
  • 1:1 Zero Calorie Sugar Substitute - I use Lakanto, to keep this recipe sugar-free;
    Sub: Regular confectioners sugar or coconut sugar (this won't be sugar free though, and also higher in calories)
  • Sugar-free Chocolate Syrup: Like this one from Jordan's
    Sub: Regular Hershey's Chocolate Syrup
  • Water
  • Unsweetened Applesauce or mashed banana or pumpkin puree
  • Non-fat plain Greek Yogurt
  • Eggs
  • Melted Butter
  • Vanilla Extract
  • Baking Soda
  • Chocolate Fudge Ganache Topping
  • Sugar Free Chocolate: Like this one from Lily's
  • Sub: Use regular dark chocolate
  • A bit of Coconut Oil
    Sub: use Butter
  • Chocolate Protein Powder Quest Nutrition again here
  • Unsweetened Cocoa Powder
  • Zero Calorie Powdered  Sugar Substitute - The same one from Lakanto
  • Unsweetened Almond Milk

Chocolate Fudge Ganache Topping

  • Sugar Free Chocolate: I used the one from Lakanto here.

  • A bit of Coconut Oil
  • Chocolate Protein Powder Quest Nutrition again here
  • Unsweetened Cocoa Powder
  • Zero Calorie Powdered  Sugar Substitute - I use Lakanto here as well (code HAYLSKITCHEN for a discount here)
  • Unsweetened Almond Milk

How to make the Perfect Chocolate Bundt Cake with Protein Powder

This chocolate bundt cake with protein powder is really super easy to make. Here's what you need to do:

  1. Preheat the oven to 350°F.
  1. Heat a small saucepan on the stove, add in the water, applesauce, butter and cocoa powder. Whisk until it's completely combined.
    Tip: Sieve the cocoa powder and flour so you don't have any lumps!
  1. Mix all dry ingredients in a large bowl - flour, chocolate protein powders, unflavored protein powder, sweetener, and baking soda.
  1. Add butter-chocolate mixture into dry mix, whisk.
  1. Add eggs, and mix again.
  1. Add Greek yogurt, chocolate syrup and vanilla and fold to combine.
    Don't over-mix the batter! Gently fold; over-mixing will make your poke cake dense because of the protein powder and wheat flour.
    Taste the batter and see if you need some extra sweetener.
    Use stevia powder to maintain the consistency of the batter and have healthy, sugar free chocolate bundt cake.
  1. Brush inside of 12-cup bundt pan with oil, and dust with cocoa powder.
    This is to prevent the chocolate protein bundt cake from sticking to the pan.
    Do this just before pouring batter into pan to prevent oil from dripping to the bottom of the pan.
  2. Pour batter into bundt pan and bake for 40 min.
  1. Stop baking when tester/knife comes out just dry, but moist.
    Don't over-bake the cake or it will get tough.
  1. Loosen edges of cake from pan using small spatula.
    Let cake cool in pan 5 minutes, then flip onto cooling rack to cool.
    (To prevent cake from stocking to pan).

Make Chocolate Ganache for the Chocolate Bundt Cake:

  1. LET CAKE COOL BEFORE ADDING GANACHE or the frosting will melt.
  1. Melt chocolate in intervals since it can burn when heating in the mircowave.
  1. Whisk all ingredients to make ganache
    Use room-temperature milk so the mix doesn't harden.
    Microwave ganache if it gets too thick.
  1. Pour ganache over cake!

How to store Low Calorie Chocolate Bundt Cake:

Store this low calorie chocolate bundt cake in an airtight container on the countertop for a couple of hours or in the fridge for upto 4 days.

For longer term, store healthy chocolat bundt cake slices individually wrapped in plastic wrap and then placed in freezer-safe zipper bags. Freeze for 2-3 months and thaw before eating.

Instructions

  • Preheat: Preheat your oven to 350°F (175°C).
  • Make Chocolate Mixture: Heat a small saucepan on the stove. Combine the water, applesauce, butter, and cocoa powder. Whisk until melted and smooth.
  • Mix Dry Ingredients: In a large bowl, whisk together the flour, chocolate protein powders, sweetener, and baking soda. Tip: Sieve the cocoa powder and flour first to ensure there are no lumps.
  • Combine: Pour the hot butter-chocolate mixture into the dry ingredients and whisk to combine. Add the eggs and mix well.
  • Add Wet Ingredients: Add the Greek yogurt, chocolate syrup, and vanilla extract. Gently fold to combine.
    Important: Do not over-mix the batter! Over-mixing will make the cake dense because of the protein powder and wheat flour.
    Taste Test: Taste the batter and add a little extra stevia powder if you prefer a sweeter cake.
  • Prepare Pan: Brush the inside of a 12-cup bundt pan with oil and dust with cocoa powder.
    Tip: Do this just before pouring the batter to prevent the oil from dripping to the bottom of the pan.
  • Bake: Pour the batter into the prepared bundt pan. Bake for 40 minutes.
    Doneness Check: The cake is done when a tester/knife comes out just dry, but still moist. Do not over-bake or the cake will get tough.
  • Cool: Loosen the edges of the cake from the pan using a small spatula. Let the cake cool in the pan for 5 minutes, then flip onto a cooling rack to cool completely.
  • Make Ganache: Ensure the cake is fully cooled before frosting. Melt the chocolate and coconut oil in the microwave in 20-second intervals (to prevent burning). Whisk in the protein powder, cocoa powder, powdered sweetener, and almond milk until smooth.
    Tip: Use room-temperature milk so the chocolate doesn't seize/harden. If the ganache is too thick, microwave it briefly for a few seconds.
  • Serve: Pour the warm ganache over the cooled cake and enjoy!

    In your instructions, you do not say at which point to add the hot water and applesauce. I am guessing before the eggs since It is hot water, I hope. Your recipe sounds good. Thank you.

    Turned out great and super useful portion size to have cake for the whole week! Only modification I made was skipping the ganache and just putting the chocolate chips straight into the batter. Thanks, Haylee!
