And the best part? You don’t need to be an expert baker (or even have an oven) to whip up this little cake. Simply microwave the batter for a cook time of 90 seconds and your mug cake is ready to enjoy. You read that correctly — this cake is ready in a total time of 2 minutes flat.

How to Make Keto Mug Cake

Mug cakes are made by pouring cake batter into a coffee mug, microwaving on high (typically for 1-2 minutes) and allowing to cool.

To make your mug cake low carb, sugar-free and gluten-free, you’ll need to swap out a few ingredients for your typical cake batter. Instead of making a cake with flour, sugar and melted butter, you’ll use a keto-friendly sweetener and low carb flour (while many recipes call for almond flour, you’ll use coconut in this one).

To make your keto mug cake, you’ll need these ingredients:

  1. Coconut oil
  2. Coconut flour
  3. Monk fruit sweetener
  4. One large egg
  5. Heavy cream (whipping cream)

You will also need a coffee mug, two bowls and a microwave.

What is Monk Fruit?

Monk fruit, also known as lo han guo, is grown in Southeast Asia. It’s been used for hundreds of years in Eastern medicine as a cold and digestive remedy.

Monk fruit, when eaten whole, contains 35% of your daily carbohydrate intake. However, the monk fruit used in paleo and keto baking is actually compounds extracted from the whole fruit. The result?  While monk fruit extract is 150 to 200 times sweeter than normal sugar, it contains zero calories and does not impact blood sugar.

Monk fruit is commonly preferred over other sugar-free sweeteners, like stevia or monk fruit. It contains antioxidants such as mogroside which has health benefits like decreased cancer risk, anti-inflammatory properties, decreased risk of obesity and improved allergy symptoms[*][*][*][*].

There are only 0.4 grams of carbohydrates per teaspoon of In The Raw monk fruit sweetener. If you do the math, it would take 80 teaspoons of monk fruit sweetener to consume 30 grams of carbs. Even then, there’s a good chance that you will still stay in ketosis.

The Benefits of Coconut

There are two coconut-derived ingredients in this recipe: coconut flour and coconut oil. Both have become common in the health and wellness industry.

Some health benefits of coconut oil include:

  • Prevents heart disease: With its abundance of saturated fats, it increases healthy cholesterol, heart health and lowers the risk of heart disease by converting LDL (low-density lipoproteins) cholesterol into good cholesterol.
  • Reduces inflammation: Studies have shown that inflammation is the root cause of most chronic diseases. A study was published showing the levels of antioxidants found in coconut oil actually treated arthritis more so than leading medications[*].
  • Improves digestion: Coconut oil helps the body with many things, including the absorption of fat-soluble vitamins, such as calcium and magnesium. It also helps your body’s digestion by getting rid of bad bacteria and increasing gut health.

Make a Single-Serving, Low Carb Dessert

Sprinkle in a few sugar-free chocolate chips (be sure to check the ingredients list carefully) on top, add half a teaspoon of cocoa powder to make it a chocolate cake, or add a little almond butter and dark chocolate for a peanut butter chocolate mug cake.

  1. There are a couple of recipes in the Dessert section that indicate a 300g content of total carbs in the recipe. Seems a little hard to believe 🙂

    1. Hi Natalie, net carbs is the real carbs– starch and sugar. They spike your blood glucose. If you spike your blood glucose, your body will use that as energy instead of using/producing ketones. Fiber, counted in total carbs, does not affect blood glucose.

  2. Any tips on substituting liquid stevia for monkfruit? Monkfruit extract is really expensive, unless it’s mixed with erythritol and erythritol gives me a horrible headache and makes me feel nauseous.
