Chocolate Protein Cake
Who doesn't love a dessert that is packed with protein. This macro-friendly low-carb cake is a delicious dessert option for anyone. This protein cake is not only easy to make but can be made ahead, frozen and snacked on for days.
Made with pumpkin to keep the recipe healthier and more keto friendly. Topped with a creamy vegan avocado frosting and a few sprinkles to finish it off. Trust me avocado frosting is the creamiest, most delicious thing you've ever tasted. Try my avocado chocolate mousse as well, it's the ultimate on-the-go low carb dessert.
With only 5 steps, this whey protein cake is a winner. My favorite thing to do is to bake the cake, cut it into smaller pieces and pop it in the freezer. That way you can have a piece every day. Simply pop the cake into the microwave for a minute or two, top it with some avocado frosting and your chocolate protein cake is ready.
Why you'll love this recipe
- Packed with protein - Made with chocolate whey protein and egg whites, this low-carb cake is loaded with protein.
- Gluten-free - I used a 1:1 gluten-free flour to make this cake perfect for those with a gluten-intolerance.
- Easy to make - With only 5 steps, this protein powder cake is one of the easiest high protein cakes out there.
- Can be frozen - This cake can be frozen without the frosting for up to 3 months.
Ingredients you'll need
- Chocolate Protein Powder - Use your favorite brand of protein powder or swop out the chocolate with a different protein powder to make a whole other high protein cake.
- Xylitol or sweetener of choice - I love using Xylitol as a low-carb sweetener because it takes just like sugar, but stevia or any other sweetener will work too.
- Gluten-free flour - 1:1 Gluten Free flour works best. To make it fully keto, swop the gluten-free flour for more protein powder or some almond flour.
- Cocoa Powder - For that chocolatey goodness.
- Egg Whites - The egg whites add even more protein to this simple protein cake.
- Egg - Only 1 whole egg is necessary
- Baking Powder - To give it that little bit of a rise.
- Pumpkin Pureé - If you're worried about pumpkin and chocolate together, don't be. You won't even know it's there but it adds a delicious texture.
- Vanilla Extract - Use the best quality vanilla extract you can find. It makes a real difference.
