Chocolate Protein Mug Cake Recipe with Egg
This Chocolate Protein Mug Cake is an indulgent recipe that is also nourishing, made with simple ingredients. By using protein powder, banana and egg, this mug cake will fuel your body and satisfy your sweet tooth. Each bite is filled with a delicious chocolate flavor and a subtle banana flavor.
This is a recipe that you can make for a filling breakfast or for nutritious dessert! One of the best parts about this recipe is that the entire recipe has 25 grams of protein.
It’s a single-serving recipe that is indulgent and easy-to-make in just one bowl. And did I mention that it can be ready in as quick as 5 minutes if using the microwave?!
Ingredient Notes and Substitutions
- Chocolate Protein Powder – You can use any protein powder that you prefer. However, I have made this with both vegan and whey protein. I recommend using vegan protein powder when baking because whey can dry out the cake texture.
- Egg – Use a large egg for this recipe, however, extra large will work if that’s what you have on hand.
- Banana – A medium sized banana is the perfect amount for this recipe. I use 3/4 of the banana in the batter then slice the rest for a topping. Make sure to mash it up well so that there aren’t massive clumps in the batter.
- Unsweetened Cacao Powder – I typically use an Unsweetened 100% Cocoa Powder, such as the brand linked.
- Vanilla Extract – You can use any brand preference of vanilla extract that you like.
- Baking Soda – This can be found at your local store and can be any brand.
- Baking Powder – This can be found at your local store and can be any brand.
Why You’ll Love this Chocolate Protein Mug Cake
There are quite a few reasons to make this recipe. However, I will go through the top 3 reasons!
- Single-serving: This recipe makes a single-serving which is great for easy cleanup (no storing leftovers) and less temptation of having cake around the house.
- High in protein: Many mornings I will crave something sweet for breakfast. However, I also want to keep it nutritious. This mug cake has the perfect balance of satisfying my sweet cravings while also enjoying a nutritious breakfast.
- Easy-to-make: You only need one bowl, a whisk and the ingredients to make this recipe. It is simple and can be done quickly if you’re tight on time.
Things to Know Before You Make This Recipe
- Protein Powder: the type of protein powder you use will impact the final result of the mug cake. A vegan protein powder will mix more seamlessly and create a softer, more “cake-like” texture than a whey-based protein powder. However, a whey protein powder will still work and be delicious.
- Banana: A very ripe banana is ideal for this recipe in both flavor and texture. The more ripe, the sweeter the banana. It is also easier to mash and mix with the other ingredients. The banana contributes to both the flavor and texture of the mug cake.
- Mixing: You can use a whisk or even a fork for this recipe. There shouldn’t be any big clumps, however, there will be some with the mashed banana.
- Mug-size: Make sure you are using a mug or bowl that is large enough to not only hold the cake batter but to expand as it bakes. I use a 14 oz mug that is oven and microwave safe.
- Baking: Don’t over-bake the mug cake as that will cause it to become dry. Whether you’re baking in the oven or microwave, it’s better to check more constantly than have a dry cake.

Frequently Asked Questions
Yes! you can make as many servings as you want by multiplying the measured ingredients based off of how much you want to make.
I also have this Small Batch Chocolate Cake Recipe that uses a few similar ingredients but is definitely more of an indulgent dessert. This recipe is a larger version, made in a loaf pan.
You can add any toppings/ingredients that you’d like. This recipe is adaptable to your flavor preferences. Some suggested toppings are banana slices, fresh fruit, chocolate chips, peanut butter or a honey drizzle. The limit doesn’t exist!
You can make this recipe vegan friendly by using a vegan protein powder. The only other thing you’ll need to do is use a flax egg instead of a regular egg.
A flax egg is 1 tbsp of ground flax seed mixed with 2 tbsp of water. Let the mixture sit for 5-10 minutes before adding into the batter. This will allow the mixture to thicken and act as an egg!
Yes! I suggest making this no sooner than the night before you plan to eat it but it is best when eaten fresh!

What can be done to lower the carbs?
I guess you could try subbing the banana for applesauce, pumpkin puree or greek yogurt? Not sure the impact it will have or how many less carbs as I haven’t tested any of these swaps.
