Low Carb Vanilla Mug Cake

We love our single serve mug cake recipes on here. From blueberry mug cakes, chocolate mug cakes and even lemon mug cakes, there is a recipe here for everyone!

When it comes to flavors, nothing comes close to the classic vanilla. It is like a blank canvas and can be dressed up in multiple ways.

Ever since I’ve started weight training regularly, I’ve made an effort to add protein to all my meals and snacks. Contrary to popular belief, you can add protein powder to desserts, especially into mug cakes. 

Enter- the protein powder mug cake! 

What is a protein mug cake? 

A protein mug cake (protein powder cake in a mug) is a single serve cake that uses a combination of protein powder, eggs (or vegan substitute), milk and other extras to create a light, fluffy and gooey mug cake.

Unlike traditional mug cakes, protein mug cakes are super low carb, packed with protein and usually are made without flour or sugar.

How to make a vanilla mug cake with protein powder

Step 1: In a large mixing bowl, combine your dry ingredients and mix well. Add your wet ingredients and mix very well, until a thick and smooth texture remains.

Step 2: Transfer your vanilla mug cake batter into a greased mug or microwave-safe cereal bowl. 

Step 3: Microwave the protein powder mug cake for 1-2 minutes, or until ‘just’ cooked. Remove from the oven and enjoy immediately!

How to make a protein vanilla mug cake in the oven

For those who don’t have access to a microwave or prefer not to use one, you can easily make this protein powder mug cake recipe in the oven. 

To make a microwave protein cake in the oven, you follow the microwave instructions but instead of microwaving it, you will bake it for 12-15 minutes at 180C/350.

Remove the vanilla protein mug cake from the oven once a toothpick comes out of the center ‘just’ clean.

How to make a protein mug cake without eggs (vegan) 

To make this vanilla protein cake vegan-friendly and eggless, you won’t need to replace the eggs with another substitute.

Simply increase the amount of liquid used by 2 tablespoons (or more, if the batter is too thick) and continue baking as normal.

A quick note on the vegan option- It will not ‘puff’ up as much and will be moist in the center

Best protein powder to use

No protein powder is created equal and many brands differ considerably.

I tried this mug cake out with several blends of protein powder and these were the best-

Vegan Brown Rice Protein Powder

A brown rice vanilla protein powder works best, as it is thick and creamy (when added to liquid) and has a very pleasant flavor. 

Depending on the brand you use, you may need to add a little extra liquid (milk or water) to achieve a thick and smooth batter. 

Casein Protein Powder

For those who can tolerate dairy, I recommend using casein protein powder. It’s thick, tastes delicious, and doesn’t dry up when baked or used in cooking. 

Casein protein powder is also keto, low carb and sugar free. 

Paleo Protein Powder

I would only use a paleo protein powder blend if you follow a strict paleo diet. It isn’t as thick as casein protein or brown rice protein, but still can be used.

Please DO NOT use any whey based protein powder, as it doesn’t lend itself well to baking, and requires very little liquid.

Ingredients

Instructions

For the microwave option

  • Grease a microwave safe bowl with cooking spray and add the protein powder, baking powder, coconut flour, sweetener of choice and mix well.
  • Add the egg and mix into the dry mixture. Add the milk of choice and vanilla extract- If the batter is too crumbly, continue adding milk of choice until a very thick batter is formed. 
  • Top with chocolate chips and microwave for 60 seconds, or until just cooked in the centre.

For the oven option

  • Follow as above, but bake in the oven for 8-15 minutes, depending on consistency desired- Mug cake is cooked once a toothpick comes out 'just' clean from the center.

Notes

* For the vegan option, you won't need any flax eggs/egg substitute- Simply omit and slowly add milk of choice until a thick batter is formed. Microwave/bake until 'just' cooked in the center.

    Absolutely delicious!
    This mug cake is my daily breakfast since the first time I made it. I have a sleeve stomach and eating enough protein per day is a big task for me as a vegetarian. Thanks for the recipe, which I shared with family and friends, it is a great start in the day!
