Recipe ingredients and how to make it even lower in calories
You can find the quantities of the ingredients on the recipe card at the end of the post.
Banana: Yes, it’s another one of those healthy banana recipes (I know, it’s kind of a cliché), but I just love it. It adds sweetness and packs a bunch of benefits! If you’re not a big fan of bananas, don’t worry. The cocoa powder does a great job of masking the flavor, especially if you mash the banana really well. When picking one out, aim for a darker, speckled banana—trust me, it’ll make your mug cake even sweeter.
Cocoa powder: This is what gives the recipe its sweetness, without going overboard.
Baking powder: No need for a lengthy explanation here—it’s simply to help the cake rise and become nice and fluffy.
Egg: Sorry to the vegans out there, but the egg is essential in this recipe and can’t really be substituted. However, if you’re aiming to cut down on calories, you can swap a whole egg for two egg whites.
Square of chocolate (optional): While this ingredient is totally optional, I always include it. It adds an extra level of sweetness that I just can’t resist. If you prefer, you can sweeten the batter with two drops of stevia instead of using chocolate (just add and mix before microwaving).
Olive oil or coconut oil (optional): This step is just to make cleaning your mug easier—it doesn’t affect the recipe at all. Honestly, I usually forget to do it anyway. A little hot water and dish soap does the trick just fine.
How to make 5 minutes keto banana mug cake (step-by-step guide)
Step 1
In a bowl, mash the banana into a “puree”. Avoid mashing it directly into the cup or adding it whole after the egg, as it doesn’t mix well that way.
Remember, the more you mash it, the less noticeable it’ll be in both taste and texture.
Step 2
Grease a microwave-safe bowl or cup with a little olive oil or oil, then add the egg and lightly beat it with a fork or whisk until some air bubbles form.
Step 3
Add the mashed banana and cocoa to the egg. Mix well, though the cocoa can be a bit stubborn to mix. With some patience, it’ll come together.
If using stevia, add it now and mix it thoroughly into your low carb banana mug cake.
Step 4
Gently fold in the baking powder.
Step 5
If you’re skipping the chocolate, microwave your cake for 2 minutes.
Since every appliance is different, it’s wise to do the toothpick test before digging in.
Step 6
If you’re using chocolate, microwave the mug cake for 1 minute and 40 seconds. Then, place the chocolate on top and microwave for another 20 seconds.
Finally, spread the melted chocolate over the cake with a spoon.
Recipe tips and notes
Bananas play a vital role in this flourless mug cake recipe, and here are a few tips to ensure you nail it just the way you like:
- Opt for bananas with spottier peels for a sweeter outcome.
- The more thorough your mashing, the smoother the texture.
- Not a huge fan of bananas? Adding a small piece of chocolate bar at the end can help mask the taste.
- Adding extra cocoa won’t sweeten the recipe; it’ll just make it bitter.
We often overlook how hot a cup can get in the microwave, so be sure to use a towel or glove to protect your hand when handling it.
