Taste and texture 

This amazing protein mug cake is a single-serve cake that, once cooked became wonderfully fudgy and cakey with pockets of gooey chocolate from the chocolate chips. Cook it longer for a more cakey, fluffy texture. It tastes like a mix between a cake and a brownie and doesn’t taste healthy at all. It is so rich and indulgent but good for you at only 230 calories and an incredible 30 grams of protein per serving!

This mug cake has the best of everything and nobody will believe it is good for you!

Ingredients you will need

Here are the simple pantry ingredients I used to make this amazing chocolate mug cake. 

• Chocolate Protein powder – Use a good quality protein powder that tastes good. You will need about 30 grams or 1 scoop. I used Orgain brand protein powder. 
• Cocoa powder – 2 tablespoons unsweetened dark cocoa powder. If you do not like it super decadent and rich then don’t use dark cocoa powder, milk chocolate works fine too.
• Baking powder – Just a little bit is needed to help the cake rise. 
• Milk – I used soy milk and have also tested this recipe with almond milk, but any milk will work. 
• Maple syrup – to add a little bit of sweetness to the mug cake. 
• Creamy peanut butter – you can also use almond butter or cashew butter instead of peanut butter. 
• Pinch of salt – to help balance all of the flavors.
• Chocolate chips – any chocolate chips will work.  I used dark chocolate chips, Lily’s brand.

How to make a chocolate protein mug cake

This is probably the easiest protein mug cake recipe you will ever make! Here are the step-by-step instructions for how to make it.

Serve immediately and enjoy!

Expert tip: The cooking time will depend on your desired cake consistency. If you prefer it fudgy then 40-45 seconds is perfect. For a cakier, fluffy texture cook it for 50-60 seconds.

Recipe tips for the best protein mug cake

• Use a larger mug with a wide opening. The cooking time will depend on the type and size of the mug you choose to use. Make sure the mug is microwave-safe (it will usually say this on the bottom of the mug).
• Spray the mug with cooking spray to prevent sticking.
• Protein powder matters – use a good quality protein powder that tastes good like Orgain or a whey protein powder like Garden Of Life that you like. 
• Mix the batter in the mug or a separate bowl then transfer it to a mug if you prefer. 
• If the batter looks too thick then add another splash of milk.
• Let the cake rest for 1 minute before eating since it will be hot. 
• Top with some more chocolate chips that will melt from the heat and make a nice topping on the cake like frosting. So good!
• To keep the calories and sugar lower, I used Lily’s brand chocolate chips.

Substitutions and Add-ins

• Top it off – have fun with toppings like whipped cream, ice cream, chocolate sauce, peanut butter drizzle, caramel, or chopped nuts. 
• Mix-ins – we love this mug cake with chopped walnuts, peanut butter chips, or dried cherries for a delicious twist. You can also stir in some strawberry or raspberry jam. So good!
• Protein powder – if you prefer it less rich then you can use milk chocolate cocoa powder and vanilla protein powder for a lighter chocolate mug cake that has the same texture but is less decadent. Note: The band of protein powder you use can affect the taste and texture of this cake.
• Dairy-free/Vegan Mug Cake – to make this cake recipe dairy-free, use a vegan protein powder, dairy-free chocolate chips, and dairy-free milk. 
• Vanilla protein mug cake: for a vanilla version, swap the cocoa powder with almond flour and use vanilla protein powder. You can also add ½ teaspoon of vanilla extract for a more vibrant vanilla flavor. I found that this version needed to cook a little longer for 70-90 seconds. It was so good topped with chocolate chips.

Storing leftovers

I recommend enjoying this protein mug cake right away as the cake can become rubbery and dry when stored.

FAQs

Can this mug cake be made in a ramekin?

Although you can cook this mug cake in a ramekin, which I have tested, It does rise a lot as it cooks. Using a larger mug with a wide opening is recommended. 

Is this mug cake healthy?

Yes, it is! This cake only contains 230 calories and is packed with 30 grams of protein and 5 grams of fiber per serving. It is naturally gluten-free, egg-free, refined sugar-free, and flourless.

How do you prevent mug cakes from becoming rubbery?

A rubbery mug cake is usually the result of overcooking or the wrong combination of ingredients. Make sure to measure the ingredients accurately and do not overmix the batter. When cooking the cake, start with shorter durations like 30 seconds, and continue cooking as needed, checking the cake in between.
