Banana Muffin In A Mug | THM: E, GF

Save for later!

I never imagined my favorite Muffin In A Mug recipe would be an E! Normally, I gravitate towards rich and buttery S Muffin In A Mug recipes, but this Banana Muffin In A Mug is so moist and flavorful, I can hardly believe it has no fat source! 

Unlike many low-fat E recipes, this one is not chewy or dense. It’s light, sweet and cake-y – more of a banana cake than a banana muffin. You know those Banana Sheet Cake recipes with cream cheese frosting? That’s what this Banana Muffin In A Mug is like! Dessert in a mug!

This Banana Muffin In A Mug doesn’t require any special ingredients to make, and is a very frugal Trim Healthy Mama recipe. The sweetness from a quarter of a very ripe banana cuts down on the need for much more sweetener (I used xylitol, but you can also use Gentle Sweet in half the amount, or Super Sweet in a quarter of the amount), and the oat flour can easily be made by simply grinding up oatmeal into a powder using your blender. 

Add an egg white for more protein and rise, unsweetened nut milk for moisture, some flavorings like vanilla extract, cinnamon, and mineral salt, and you’ve got the makings of a wonderfully sweet, single-serve THM E breakfast, snack, or dessert!

I have not tried baking this Banana Muffin In A Mug in the oven yet, but if you don’t have a microwave, you should be able to bake this (and most other Muffin in a Mug recipes!) at 350 F for a 10-15 minutes, using a toothpick to check for doneness. 

Since there’s no fat source in this Banana Muffin In A Mug, you have room to add a teaspoon (or 5 grams) of butter, peanut butter, nuts, or sugar-free chocolate chips if you like that in your Banana Muffins.  

Yield: 1 serving

  1. BEST MUFFIN IN A MUG EVER! I seriously want to make this all day every day. I added a teaspoon of Lily’s choc. chips and it was amazing. Thank you for this great recipe!

  2. This was absolutely the best mug cake I have ever made, I did add 1/4 tsp of banana extract along with the vanilla… everything else was the same. Love Banana Bread. Thanks so much for this recipe!!!

  3. I was making this today thinking I wonder if I could just make it as pancakes. Wouldn’t that be delicious! What do you think? Would it be possible?

  4. Do you have a similar recipe for a big batch cooked in the oven? I’m thinking I made them once, but now I can’t find the recipe. Thanks for all you do !
