Keto Chocolate Mug Cake (The Microwave Recipe)

Keto Chocolate Mug Cake (The Microwave Recipe)

Who doesn’t love eating, right? Who on earth can resist food?

Well, not me. 

I have always been a big fan of foods, most especially the sweet ones.

I can spend all day eating them and would still munch on them the next day.

Literally, I enjoy every bite of it as if I’m brought to the heavens by the angels. 

Perhaps, you are on the same page as me.

Admit it!

The thing is, I am getting fatter and fatter already.

But it turns out that I can still eat my favorite dessert without the guilt of adding extra pounds on my weight and you can try this too – a Keto Chocolate Mug Cake. 

Mug cakes have become a popular dessert for the past few years.

They are very easy to make and can be made in small batches only.

It can be enjoyed quickly and it has the right portion for a single serving.

A mug cake is usually a single serving of cake or brownie batter that is stirred up into a ceramic coffee mug and then microwaved for a couple of minutes.

If you’re the only one in your house on a keto diet, you can make a guilt-free portion of keto-friendly mug cake just for yourself.

Is coconut flour OK for a ketogenic diet?

Yes, coconut flour is very much OK for a ketogenic diet.

Coconut Flour is very high in fiber and low in carbohydrates so it is perfect to use in baked goods such as bread and desserts.

Since it is high in fiber it usually only requires about 1/4 the amount of substituting in place of normal flour or almond flour

What does coconut flour taste like?

Coconut flour has a subtle taste.

It has a mild flavor that does not empower other flavors when combined.

It still smells like coconut and doesn’t have the neutral taste of cassava flour or wheat.

This is a good wheat substitute in case you are on a diet.

What is the difference between salted and unsalted butter in baking?

The most distinguishable difference between salted and unsalted butter is salt.

Salted and unsalted butter are both made with cream, but salted butter has salt while unsalted butter doesn’t contain salt.

Personally, I use unsalted butter every time I bake.

What is the difference between pure vanilla and vanilla extract?

I thought they are the same but it turns out that pure vanilla is made from natural vanilla beans mixed with water and alcohol.

It does not contain any artificial color, flavor, additive, or preservative.

On the other hand, vanilla extract is a laboratory-made alcohol solution with vanillin which has been added with artificial color.

It is made by liquifying or softening and filtering vanilla pods in water and alcohol solution.

How do you store keto mug cake?

Typically, you should consume a keto mug cake in one sitting but if you can’t consume it all at once, you can store it at room temperature for a day or put it in the fridge for 2 – 3 days.

Keto mug cakes are best eaten when freshly baked. You can reheat it too, but the texture will already be a little different.

Can you freeze keto mug cake?

Yes, you can freeze a keto mug cake. You have to tightly wrap it with a plastic wrap before putting it inside the freezer.

In case you want to eat it, allow it to thaw in the fridge first before reheating it.

When reheating, you can add some butter to make it moist.

What kind of butter is best for a keto mug cake?

Unsalted butter is the best to use when making a keto mug cake.

Aside from allowing you to have full control over the level of salt in your keto mug cake, it also brings out the sweetness of the cream.

Using unsalted butter in your keto mug cake will give you a cleaner and more buttery taste.

Make sure that your mug is microwave-safe. Most ceramic mugs are not microwave-safe. To find out if your mug is microwave safe, set your microwave oven to its highest power setting, fill a bowl with water, place the bowl and the mug in the microwave and microwave them for a minute. If the mug becomes warm or hot, the mug is not microwave-safe. If the mug is cool and the bowl of water is hot, the mug is microwave safe.
