This flourless almond butter mug cake is just four ingredients and ready in minutes. It is fluffy, moist and you won’t believe it doesn’t contain any flour.
With the hot weather, we’ve been avoiding turning on the oven whenever possible, which is why my mug cake obsession comes in handy. I was craving something sweet the other day and was able to whip this up in minutes. It was definitely satisfying.
The last time I made a mug cake was for my local morning show appearance a few weeks ago, when I demonstrated my flourless peanut butter mug cake. Making this cake brought back memories of that morning’s prep. I was in my kitchen making the finished mug cakes so that the host would have something to taste. I had just finished making the flourless peanut butter mug cake and it was one of the prettiest ones I’ve ever made. It came out even, smooth and just slightly overflowing over the top of the mug.
And then my husband accidentally ate it. Yup, that happened.
You see, in my paranoia that I was going to mess up and forget a crucial ingredient, I made two of each one. That way I could taste one and be rest assured I made it correctly, and still have one left for the TV segment. Well, when I told Mr. K to please taste the one I had already deemed the ugly taste tester one, he did. But he thought he was supposed to taste everything, so then he went on and took a bite out of my perfect one too.
He did feel really bad after. I was able to make a new one, but the extra few minutes actually had us scrambling to get there on time and the new one just wasn’t nearly as pretty. Oh well. It’s something to laugh about now and at least everything else went well with the segment.

Flourless Almond Butter Mug Cake
Ingredients
- 2 1/2 tbsp creamy almond butter (see note)
- 1 large egg
- 3 tsp granulated white sugar (see note)
- 1/8 tsp baking powder
Instructions
- Combine all ingredients into an oversized microwave-safe mug. This cake does rise quite a bit, so make sure your mug is at least 12 oz.
- Mix with a small whisk until batter is completely smooth. Make sure you whisk until all the egg has fully been mixed in, otherwise it won't bake properly. You should have an even, brown batter. It really helps if you are using a whisk rather than a fork.
- Microwave for about 1 minute 20 seconds. Let cake cool a few minutes before eating. If desired, you can also top with powdered sugar or syrup.
Notes
- I prefer to use Jif brand because of its consistency.
- I find there's just enough sugar in this cake, but if you have more of a sweet tooth you can increase the amount.

This recipe is amazing. I was craving something quick and Gluten-free. I stumbled upon it and it looked perfect
I was still hesitant trying because I’m not a very good cook. Normally recipes on the internet don’t come put too well.
I surprised myself pleasantly when it turned out so good
Honestly first time ever reviewing and commenting on recipe
I just want to add that the ingredients were all available in my pantry and I am so thrilled that I’m gonna make one more
Do you think I can maybe double the recipe and make for two people at once in a bigger mug/bowl ?
You can double the recipe, but you should cook the cakes in two separate mugs one at a time for the best results.
We’re so glad you loved it!
Would love to see more flourless and flour alternative mug cakes. For my Ketogenic diet I have to significantly reduce carbs and sugar. I can make this with monkfruit sweetener and still stay on plan. I can even add butter or Cream cheese frosting.
I’ve actually got quite a few, but I’ll keep making more!
