A spice cake you can eat any time of the year!
I have to be honest right from the start, guys. I was looking for a delicious mug cake with a gingerbread flavor, but since it’s the beginning of June, I didn’t think that most people would be looking for my gingerbread mug cake recipe right now.
Then I realized that spice cake is really just a way of saying “gingerbread that is acceptable to eat year-round.”
While the flavor profiles are a bit different (less ginger here), if it’s a cinnamon-y and nutmeg-y mug cake you’re looking for, you are in the right place!
I was positively impressed with how soft and cake-like this mug cake truly was. Most mug cakes are really eggy, and tend to be dominated by the flavor and texture of the egg white or yolk. This one isn’t like that at all!
I think the key is to really get in there with a fork and whip the egg until you can’t see any of the whites at all. The better you can incorporate it, the less eggy it will taste.
Single serving cake in less than 5 minutes? Yes, please!
To make this delicious little cake (which you can totes eat any time of day from breakfast to dessert!), you’ll want to start by melting your butter or coconut oil. It’s best to microwave in short bursts of 20 seconds or so, especially if using butter, to prevent splattering.
After the butter/coconut oil is melted, add in all the remaining ingredients and beat with a fork until smooth. As mentioned above, you want to make sure there is no trace of egg white left, otherwise you will have a very “eggy” texture.
Microwave for approximately 90 seconds, depending on the power of your microwave and the shape of the container. I used a ramekin in a medium-power microwave, and 90 seconds worked just fine for me.
Tall, skinny mugs usually take less time, but it also depends on the material. After you make your first mug cake, you will know what the best time is for you.
These are best enjoyed immediately, but can be stored in the fridge for 3-4 days in an air-tight container if needed.
Can I use almond flour instead of coconut flour?
Yes you can. Rather than 1 tablespoon, you should be fine using 4 tablespoons (1/4 cup) of almond flour. This is the approximate substitution I find works best for these two flours. The super-fine blanched almond flour tends to work the best, but you could also use the almond meal/course almond flour if that is all you have.

Keto Spice Mug Cake
- 1 tablespoon butter or coconut oil
- 1 tablespoon coconut flour
- 1 tablespoon granulated sweetener of choice
- 1 large egg
- 1/4 teaspoon cinnamon
- 1/8 teaspoon pumpkin pie seasoning (or blend of cinnamon, allspice and nutmeg)
- 1/4 teaspoon molasses
- 1/8 teaspoon vanilla extract or a pinch of vanilla bean powder
- 1 tablespoon refined coconut oil
- 1 teaspoon granulated sweetener of choice
For Mug Cake
- Melt butter in a ramekin or mug in 20 second increments until melted.
- Mix in all other ingredients, making sure that the egg is fully incorporated. I recommend using a fork and really whipping it until you don't see any egg whites at all. This helps the texture tremendously.
- Microwave for 90 seconds to 2 minutes, depending on the power of your microwave.
For Optional Frosting
- While the mug cake is cooling, mix coconut oil and sweetener together in a bowl. If your coconut oil is very cold, you may need to microwave it for 5-10 seconds to soften it. Watch closely that it does not melt in the microwave, you just want it soft and spreadable. If your coconut oil is liquid, you will want to put into the freezer until it reaches a frosting-like consistency. Be sure to stir often and watch closely so it does not become too hard. Top the cooled mug cake with the frosting.
