This keto vanilla mug cake is good. I mean really good. I tested more than fair share of mug cakes in creating a recipe that I thought was good enough.

This is such a simple keto dessert recipe that is ready in just a few minutes. So, it is one of those recipes most of you will love. Bonus points for the fact it also single serve.

The Ingredients

Here is all you need to make this keto mug cake recipe. You will need a neutral-tasting oil, collagen powder, coconut flour, egg, sour cream, baking powder and vanilla extract.

How to Make It

If you haven’t made any keto mug cake recipes beforehand you are going to love this. To make it all you need to do is place all the ingredients into a large mug or a 10cm x 7cm ramekin and mix until combined.

Place the vanilla mug cake into the microwave and cook 90-120 seconds. Tada! That is it. Our keto vanilla mug cake is so hard, right?

Now I have added an optional scoop of our very delicious keto lemon curd to the mug cake recipe. It tastes so good together with a just a few berries as well.

FAQs and Substitutes

What oil or fats are best to use? Use any neutral tasting oil like MCT or light tasting oil. Butter or ghee can be used as well.

Keto Collagen what is it and where do I get it? Keto Collagen is available form most low carb suppliers like Keto Eats Australia or direct from Aussie business Locako. (A fave of mine AND an affiliate – use the coupon MEGAN15 for 15% off at checkout). Keto collagen is good for our hair, skin, nails and joints. In fact it has a very long list of supposed health benefits.

Can I substitute the collagen for something else? Yes you can choose to use some Whey Protein Isolate or almond meal in its place.

I am not a fan of keto mug cake recipes with coconut flour what can I swap it for? The coconut flour is very absorbent in this mug cake recipe. Can use golden flaxseed meal or chia flour in its place. If using almond meal replace the coconut flour with 2-3 tbsp.

I don’t have a microwave? Yes, you can still bake a mug cake in the oven. Simply bake at 180°C for 10-12 minutes
