Gemma’s Pro Chef Tips
- This is best eaten as soon as its cooked but if you only need one serving, fill both mugs and cover and refrigerate the second one before cooking. Cook and eat within 2 days.
- You can use honey or agave in place of the granulated sugar if you prefer to use an unrefined sweetener.
- For an extra boost of nutrition, stir in a teaspoon of spirulina powder into the dry ingredients.
- Try our Microwave Granola in a Mug for another healthy microwave mug meal.
- This can be made with another nut or seed butter if you wish. Try making this with our Homemade Almond Butter!

Chocolate Banana Mug Cake Recipe
Ingredients
- 1 medium-sized banana, ripe
- ¼ cup (2 oz/57 g) peanut butter (or any nut butter)
- 1 large egg
- 3 tablespoons unsweetened cocoa powder
- 2 teaspoons granulated sugar
Instructions
- Mash the banana in a small bowl with a fork.
- Add the nut butter and egg and mix thoroughly.
- Stir in the cocoa and sugar and mix until smooth.
- Divide the batter between two small mugs.
- Microwave one at a time for 45 seconds, and then in 10 second increments until risen and firm. (Take care not to over cook or the cake will dry out fast.)
- Important note: The cooking time is based on our micrwave which is 1200 watts. Check the wattage of your micrwave as your cooking time might be very different. Some micrwaves can take up to 2 minutes to cook this cake but it's better to go slow and check frequently so it doesn't overcook and get tough.
- This is best eaten straight away. If you only need to make one, cover and refrigerate the second mug before baking. Cook and eat within two days.
IF YOU HAVE NUT ALLERGIES – Just swap out PB for sunflower butter!
You might need to add a little more sweetener depending on the brand but otherwise this works fine.
Hi, I made this today. It’s insane!
I substituted the egg with half a banana (following the chart).
I also got inspired by another Gemma’s mug chocolate cake recipe, so I added some extra peanut butter on the bottom of the mug (under the batter).
I couldn’t feel the banana at all, it just tasted like rich chocolate.
The texture was very soft and marshmallow-like.
Hi Gemma,
May I substitute the egg with more banana?How will it affect the texture?
Hi Gemma! Can I prepare the batter 12 hours in advance?
Yumm can’t wait to try this 😍😍😍
If I don’t have cocoa powder, can I just leave it out? If not what can I put instead? It doesn’t have to have chocolate.
I’ve tried this recipe today with 2 small banana and sugar substitute since my father is diabetic. It was so good and he enjoyed it for breakfast. Made it in 800 watts microwave for 1 minute 20 seconds and turned out just great. Thanks gemma
Love,
Ika
Made this today and it was delicious! Can’t wait to try your other mug cakes.
I wanna try this but can I use plantain instead of normal banana?
These sound great! Could frozen bananas work (if thawed of course)? Liquid drained or no?
