Keto Peppermint Mug Cake


Keto Peppermint Mug Cake

I set out to create a light, fun and PINK Valentine’s Day treat.  I mean, it can be for ANY occasion, but Valentine’s Day just happens to be right about the corner.  The result was this beautiful keto peppermint mug cake.  Perfect.

I’ll admit that I am not a fan of large desserts.  Only because then I eat them for days.  I like the “one and done” desserts where they are gone after a single serving.  This one makes 2 servings, but I suppose you could turn it into one giant dessert (I won’t tell).

The great thing about these mug cakes is that you can control the sweetness!  The cakes themselves are semi-sweet. Not too sweet but just sweet enough.  The frosting is pretty much PURE delightful sweetness.  I just drizzle it but if you want more sweetness, then load up more on the frosting.  

Want to make it extra fun?  Turn the topping red or pink!  Maybe even dye some unsweetened coconut red and sprinkle those on top!  

Great creative and have some fun!

Now, let me warn you.  When you take it out of the microwave, it probably won’t look pretty.  Maybe it spilled over the edges.  Maybe it is lumpy. 

But don’t fear.  Why?  Several reasons: 1) It will deflate a bit, so if you didn’t overfill the cup with batter then it will deflate to an appropriate level and 2) you are going to flip it anyway so it will look beautiful no matter what!

Erythritol and liquid stevia – my favs!  

I did make this twice and one time I forgot the liquid stevia (oops) and it tasted just as good.  So if you don’t have it, feel free to leave it out.  You will still have a sweet, wonderful dessert.  And especially with the sweet topping, you’ll never notice!

Keto Peppermint Mug Cake



I was thinking of pink desserts and the peppermint flavor was on top of the list.  Perhaps I think I was thinking of candy canes or something.  I love peppermint, but not the overpowering kind of peppermint.  I like the subtle flavor.  You know, the kind that doesn’t burn your mouth or make drinking water after freeze your mouth.

In the recipe, there is a range given for the peppermint flavor.  Use the lower end of the range (like I did) if you want a more subtle flavor and the upper end of the range if you want a more powerful peppermint flavor!

I found this Frontier Co-Op (Organic, Non-GMO) Peppermint flavor at Natural Grocers the other day when I was trying to find caramel extract.  No luck on the caramel, but I did walk away with peppermint and also the lemon flavor. 

I made mug cakes with the lemon too – you can check those out HERE!


Optional of course.  I know there is a lot of conflict over fruit and keto.  My stance is that fruit is overrated (even too much fructose can be bad).  But a small dose of berries on occasion or even daily is not a bad thing.

Aside from keto, my issue with fruit is the fact that I like to think of eating in a more Paleo way (aside from my desserts of course). 

I’m not claiming to be Paleo compliant, even though I once was.  But the concept behind Paleo makes sense to me, just like keto does.  Our diets have changed so drastically in the last 100 years and evolution has yet to keep up.  


Think of fruit long ago.  Was it available year round?  Or was it available for a few weeks/months a year and then not again for a while?  Yes, the latter.   Yet we seem to think gorging on fruit DAILY is the best answer for our bodies.  

So, again, I think fruit on occasion is great.  A tiny handful per day, twist my arm, but ok.  ESPECIALLY berries.  Those are the best and most compliant for a keto lifestyle.

Mug Cake

  1. Use melted butter to coat mug cups (I used 2 small cups)
  2. In a small bowl, mix all ingredients well.
  3. Add to mug cup(s).
  4. Make sure it doesn't fill much more than 1/2 the cup because it will rise
  5. Microwave for 90 seconds.
  6. Remove from microwave and let cool for 2-3 minutes.
  7. Flip upside down onto plate. It should EASILY come out due to the butter coating.
  8. Let cool for a few moments.


  1. Meanwhile, mix topping ingredients in a small bowl and combine well.
  2. Topping should be thick but pourable.
  3. Drizzle just a small amount on the mug cake(s). You may have extra.
  4. Top with berries (optional)
