Keto Coconut-Lemon Mug Cake Recipe

If you’re on a ketogenic diet, you’re brave enough to give up indulgences like sugary treats. But guess what? You can still satisfy your sweet tooth with keto desserts, like this easy-to-make Keto Coconut-Lemon Mug Cake! It’s a single serving, so you don’t have to worry about going overboard.

Eating healthy fats is a key component of the keto diet. MCTs, or medium-chain triglycerides, are a form of saturated fatty acids that are especially useful to incorporate into the keto diet. Coconut oil is a rich source of MCTs, but you can also get your daily dose in supplement form.

This particular recipe incorporates MCT oil powder. The healthy fats in MCT powder are converted to ketones, which can help sharpen your focus, boost energy and enhance weight loss.

Powdered MCT is easier on the digestive system than MCT oil in its raw form.  The powder is also easier to incorporate into baked goods, like this guilt-free mug cake!

The MCT powder here is used in place of butter as a fat source. (If you don’t have MCT oil powder on hand, you can substitute 1 tablespoon of grass-fed butter or coconut oil per scoop.)

Consuming MCTs has never tasted so good. Trust us.

    You do realize that by microwaving this mug cake you have destroyed all the nutrients and benefits of the MCT oil? If you were really concerned with your health you would stay FAAAAR away from microwaves! They literally change the molecular structure of your food into something that your body can’t recognize. So not only are you wasting time and money on ingredients but you’re consuming nothing but empty calories. I highly suggest you do some research on this if you’re aiming for good health.

    Jess, I totally agree with you!! Scientists are doing research about how the microwave messes with the gallbladder and the pancreas. When the food is nuked it does change the molecular structure, and the gallbladder doesn’t know if it’s supposed to release starch, acid or alkaline to digest wherever the microwave nuked!! This causes stress on one’s pancreatic system etc., and could very well be one of the main causes of type 2 diabetes mellitus. Please do your own research on microwaves, and their dangers.
