What Is A Mug Cake? 🎂

Simple. A cake in a mug. Made famous initially by the Nutella Mug Cake, it’s essentially microwaving a handful of ingredients to produce a cake in a mug.

Our take on this is to use Whey Protein as the core ingredient to ensure a high protein content and balance the texture with our other ingredients.

You can really take this recipe and make it your own. I always tend to use high-quality whey protein, and Optimum Nutrition is the brand I’ve chosen for 10 years. If you want to go for a bold chocolatey flavor, then ‘Double Rich Chocolate’ is great. For a no egg protein powder mug cake, ‘Cookies and Cream,’ ‘Chocolate Peanut Butter’ have both worked a treat too. Optimum Nutrition is great as it includes 5.5g of BCAA’s, too, which is a bonus.

However, our top pick from multiple rounds of testing goes to Promix – their ‘Raw Chocolate’ and ‘Peanut Butter Chocolate’ protein powders taste significantly better than any other powder and are ethically sourced and lab-tested.

Cocoa powder is important to get right for a no egg protein powder mug cake. Given that you’ll be using such a little amount it’s worth spending a little extra for a higher quality premium product. Seven Mills do a fine powder, as do Naturya.

I’ve tried this recipe with whole milk, semi-skimmed, and almond milk. If you can spare the extra calories I’d recommend whole milk – but almond milk works just as good. Whole milk gives it some extra volume and flavor which isn’t that bad for a total of 4 grams of sugar.

No Egg Protein Powder Mug Cake Recipe


  • 30g / ¼ Cup Optimum Nutrition Whey Protein Powder
  • 5g / 1 Teaspoon Cocoa Powder or Crushed Cacao Nibs
  • 2.5g / ½ Teaspoon Baking Powder
  • 60ml / ¼ Cup Milk


Mix the Whey Protein, Cocoa Powder, and Baking Powder carefully in a mug with a teaspoon.

Add the milk and keep stirring until everything has mixed and you have a nice consistency.

*Important part*

Microwave time. Start with 30 seconds. Check on it, then another 5-10 seconds whilst watching carefully. You don’t want it to be a solid cake – the goal is to have it half-baked and gooey.

It might take a few attempts to get this right, and when you do it’s a game changer. It’s important not to let the mixture overcook as whey has a propensity to turn very spongy and inedible.

When microwaving, keep watching (especially the last 10 seconds) as the mixture rises, and stop roughly as it reaches the top of the mug.

When you take it out the texture should be gooey, moist, and very chocolatey.

Frequently Asked Questions (FAQ’s)

Do mug cakes actually work?

Microwave mug cakes do actually work. They’re simple to make and often require very few ingredients and aren’t time intensive. In most cases, a mug cake won’t taste better than an actual cake, however, they’re versatile and can be healthy, high protein, vegan, and gluten-free – a great snack for the sweet tooth.

Mug cakes are often made in the microwave, although there are oven options. They’re easy even for those with little no cooking experience and can be spruced up with chocolate chips, a teaspoon of peanut butter or any other nut butter.

Is it OK to microwave protein powder?

It is absolutely OK to eat protein powder mug cakes! They are a quick fix to a sweet tooth and can be adjusted to be high-protein meals with delicious fillings like chocolate chips or a touch of dark chocolate.

Whether you use vanilla vegan protein powder or peanut butter protein for a slightly different twist, you can always add some exciting toppings like maple syrup or a few healthy nuts.

Can you add protein powder to cakes?

You can add protein powder to cakes but it will often negatively impact the texture of the cake. Whey protein typically creates a more chalky consistency that isn’t as soft and fluffy as most baking flours.

You can experiment with different dry ingredients such as coconut flour or almond flour, and possibly other nut butter to find a consistency you like.

Does baking protein powder destroy it?

Baking with protein powder does not destroy the protein. Cooking with protein powder, as with any other type of protein (meat, eggs, fish) denatures the protein, which is essentially changing the structure which effects the digestion in your body and nothing more.

Denatured protein doesn’t mean that you lose the nutritional value – it remains the same.

Why are mug cakes so popular?

Protein mug cakes are so popular because they can be made so quickly, with regular household ingredients, and taste exceptional.

A lot of athletes tend to have a sweet tooth or cravings for sweet things post-workout, and a protein cake does just this. The benefits are a low-calorie high protein cake with a variety of easy ingredients like Greek yogurt, coconut flour, peanut butter, coconut oil, vanilla extract, and still be low carbohydrates, includes fiber, and is microwave safe!
