This protein mug cake is the easiest mug cake you’ll ever make! Not only is it high protein, gluten-free, and dairy-free but it also requires only 7 ingredients and minutes to prepare.
Growing up, one of my favourite no-fuss desserts was easily MUG CAKES. Aside from my easy bake oven (millennials know what i’m talking about), mug cakes were my OG kid-friendly dessert that made me feel like a low-key cake boss.
Not only did it satisfy my cake craving without the need to whip out a bunch of baking equipment, but it’s also a single serving which means no mess (and no sharing with my sis haha).
Better yet – It’s next to impossible to mess up because all you need is a microwave, two minutes to spare, and a few very basic ingredients. So as a dietitian mama, I wanted to put a healthy spin on one of my long-time favs by creating this protein mug cake! So if you aren’t a fan of mug cakes yet, I promise this recipe will make you a converter.

Why This Recipe Works
There is pretty much nothing that I DON’T love about a good mug cake but this protein mug cake has won me over for more than a few reasons.
- Takes only minutes to prepare!
- A high-protein snack option (8 grams per serving)
- Only requires 7 ingredients
- Gluten & dairy-free
- Kid friendly
Coconut Flour – to make this recipe gluten free, we are using coconut flour. I also love using coconut flour as I find it really enhances the flavour profile in a big way.
Almond Milk – To keep this recipe dairy-free, we opted for almond milk. However, you can also use oat, soy, or any other plant-based milk of choice. If you don’t need to make this dairy-free, you can use regular cows milk instead.
Protein Powder – to make this protein mug cake high in protein, we sneak in some vanilla protein powder to really boost up the satiety factor. You can certainly play around with the flavour profile here, depending on what you have on hand and what you prefer.
Baking Powder – Baking powder is a leavening agent which causes the mug cake to rise and gives it the same airy texture of a regular cake.
Flavourings – To flavour mug cake, we added in some vanilla and maple syrup. If you wanted to take things up a notch, you can also add in some cinnamon or cocoa powder as well.
How To Make This Recipe
Step 1: In a mixing bowl, combine egg, maple syrup, vanilla extract, and almond milk.
Step 2: To the same bowl, add dry ingredients and mix until combined.
Step 3: Portion into a microwave safe mug (about half way) and heat in microwave for 90 seconds. Let rest in microwave about 30 sec-1 min. Top with sprinkles and enjoy!
There are a few little nuances that are important to ensure that your protein mug cake turns out just right. For one, be sure to not over-mix your batter as this may result in a tough texture.
You also don’t want to over microwave. I like to nuke for 30s increments for 1.5 minutes and let it sit. But remember – every microwave is different. So if your microwaving on high, your mug cake may require less time.
No I would not suggest making it in a glass UNLESS it is a microwave safe glass mug. Otherwise, ideally you would want to use a microwave safe or ceramic mug to make this recipe.
Honestly, what ever your heart desires! If I am not adding sprinkles to this, I like to add chocolate chips, berries, or maybe a bit of ice cream if I am in the mood for something a bit more decadent.
I personally have never tried but you can certainly give it a shot and let me know how it goes. I would suggest baking at 350F for about 10 minutes or so and be sure you are using an oven safe mug!
This protein mug cake is made to serve, so I wouldn’t recommend making it and storing in the fridge for a later time. BUT you can certainly whip up the batter ahead of time, store in the fridge, and pop it into the microwave anytime the craving hits.
