Why This Recipe Works
Coconut flour is amazing to use and tastes really great while being keto friendly. This is a great ingredient to cook with instead of regular flour while staying on track. I love keto coconut flour recipes.
I have tried coconut flour bread and coconut flour pancakes and loved them both. So, I knew this mug cake with be a hit too on the keto diet.
Ingredients
- Butter. It’s best to use real butter.
- Coconut Flour. Keto friendly substitute to use instead of traditional flour.
- Swerve Granular Sweetener. This is easy to cook with.
- Egg. Use a large egg.
- Vanilla Extract. Pure vanilla is best.
- Swerve Confectioner’s Sugar. This is optional but so delicious for the topping.
The complete ingredient list is at the bottom of the post.
Substitutions And Additions
- For the Sweetener – I used Swerve erythritol sweetener for this recipe, but any brand will work. You can also use Monk Fruit sweetener or if you’re not following a low sugar diet, you can use real sugar as well.
- For the Butter – You can also use coconut oil instead. I find that butter makes the mug cake more moist and soft but the oil will work as well.
- Vanilla Extract – This is needed to give this mug cake a slight vanilla flavor that accents the coconut flour well. Make sure to use a no sugar added option.
- Cocoa Powder. Add cocoa powder to make a chocolate coconut mug cake with lots of chocolate flavor.
- Cream Cheese. Cream cheese is also delicious for a creamy texture and another decadent dessert option.
- Chocolate. Add sugar free chocolate chips for a dessert that tastes like a chocolate chip cookie or add dark chocolate. Yum!
- Topping. Top with Keto Whipped Cream, sugar free maple syrup or low net carbs ice cream.
- Berries. Add berries or mix in berries before cooking for something different. This turns out like a cobbler if you bake them inside the mixture.
- Peanut Butter. Add a dollop of peanut butter to the low carb recipe.

Frequently Asked Questions
The cook time for this recipe will vary slightly depending on your microwave. Check your microwave power and adjust the cook time based on that power setting.
Most microwaves cook between 600W, 800W or 1000 W.
Here are a few ways to adjust the cook time based on your microwave. The power setting of your microwave is usually posted on a sticker inside the microwave.
600W – This is the lowest power of microwave, so you will need to add 20-30 seconds to the cook time of the mug cake to make sure that it gets cooked all the way through.
800W – This one has slightly more power, so just a little more cook time would need to be added to this recipe. I would add 10-15 seconds to the cook time.
1000W – This is the highest power types of microwaves and the most common in the US. This is the one that we used when testing this recipe and we found that 60 seconds was the perfect amount of time.
If you have never tried a mug cake before, you might be a bit nervous to eat a cake that was made in a microwave.
There is an egg used to make mug cakes, but the egg and mixture does cook in the microwave making it perfectly safe to eat.
Just make sure that the cake is cooked all the way through and you’re fine to enjoy a cake made in your microwave.
Generally, when I make this recipe, I enjoy it right away while the cake is warm. However, you can keep this mug cake covered at room temperature for up to 1 day.
To reheat it, place it in the microwave and heat it for 15-20 seconds and then it’s ready to enjoy.
Pro Tips
- Choose the Right Mug: We used a 14 oz mug for this recipe, and it worked perfectly with plenty of room for the cake to rise. A 12 oz mug will also work well but make sure it’s microwave safe.
- Test Your Mugs: Every microwave is different, so try a few mug sizes or shapes to find what works best for even cooking in your microwave.
- Mix Thoroughly: Be sure the cake batter is completely combined before microwaving to avoid dry or uneven spots.
- Avoid Overcooking: It’s better to slightly undercook your mug cake at first. You can always add a few extra seconds if needed. If your microwave runs hot, reduce the cook time a little.
- Leave Room to Rise: Do not overfill your mug, as the batter will expand while cooking and can overflow.
- Customize Your Toppings: Change up the flavor with fun toppings like sugar-free whipped cream, fresh berries, shredded coconut, or a drizzle of keto-friendly chocolate syrup.
