Why You Should Make This Chocolate Mug Cake

There are a lot of good reasons to make this cake. The ingredients are healthy, whole foods.

It’s also more nutritious than a pre-packaged dessert. Homemade is always the healthier option.

There are 23 grams of protein. The mug also has a high level of potassium, which is great for your diet.

This is a great option when you are feeling like something a little fancy and delicious. You won’t feel guilty after you learn about the five simple ingredients.

Mixing a banana and egg together is a healthy cooking hack that you can use in several different ways. Both ingredients are high in protein, and you usually have them on hand.

When bananas and eggs are mixed together, they create a cake-like texture. You could add several different flavors to these two ingredients and get delicious results.

We are using a few types of chocolate in this recipe to intensify the flavor. Adding the chocolate brings the banana-egg mixture to another level.

Cocoa powder offers a great way to add chocolate flavor without adding sugar. The dark chocolate chips add antioxidants to the cake and create delicious melted-chocolate bites.

Be sure to try and find unsweetened cocoa powder and dark chocolate chips you can get here. You won’t need the added sugar that most standard brands contain.

The unsweetened varieties are much better for you.

How to Make Protein Mug Cake

Find your favorite mug and get your ingredients.

Here’s what you’ll need to make the protein cake:

  • banana
  • egg
  • vanilla protein powder (or chocolate protein powder)
  • dark chocolate chips
  •  cocoa powder

Mash the banana with a fork. You can do that in a separate bowl or right in the mug that you will be using.

Using a ripe banana will be much easier here. It will be softer and easier to mash.

Add the egg, cocoa powder, protein powder, and chocolate chips. Combine them all together.

Try to smooth out any clumps of banana. The cake will be lighter and fluffier if you mix everything together well.

Pour the ingredients into a mug (if you weren’t already mixing in the mug).

Place the mug in the microwave and cook for 1-2 minutes. Decrease the cooking time if you want the texture to be more like a chocolate lava cake.

Enjoy the warm cake right away! It’s so satisfyingly delicious with a hot cup of coffee or tea.

Can You Add Protein Powder to Cakes?

Adding protein powder is a really great way to increase the protein in baked goods.

You can add as much as 6 grams of protein by adding the powder to your recipes. It also offers a great way to experiment with flavors.

This recipe calls for vanilla protein powder. This protein powder could be used for that. Feel free to also try chocolate, coffee, or even peanut butter flavors.

Experiment and have fun with it!

What Can I Replace Protein Powder With?

If you don’t have any protein powder – don’t worry. There are a few other ingredients you can try.

We really want to get that added protein. The added protein provides us with the energy we need for the day.

What can you use? Let’s explore the options:

  • Substitute the protein powder with an equal amount of almond flour or other gluten-free flour
  • Mix in 1 tablespoon of hemp powder to the mixture before cooking

Note: You can omit the protein powder all together (and not replace with flour). The cake might turn out a bit more gooey and less dense.

Is It OK to Microwave Protein Powder?

There is no issue with microwaving something that has protein powder. The protein powder is just as functional served at room temperature, cold, or hot.

The heat may denature the protein to some extent (meaning slightly alter their structure). However, the amino acids and general purpose of the protein powder will remain unaffected.

In fact, protein powder is perfect for trying in different ways. It’s not just for shakes.

Get creative! Now you know you can add protein powder to many other things like gluten-free muffins, pancakes, or even your daily cup of coffee.
