Making an oatmeal mug muffin couldn’t be easier! Use a packet of instant oats to make a muffin in 2 minutes. These are the best way to make a delicious hot breakfast in no time. Vegan, soy free, and gluten free too!
Your kids will love these! I have seen recipes for mug cake and tried a few of the recipes that I found. It was amazing to see that you could actually bake in the microwave. Who knew?
One morning, I was heating up some instant oats for my son, and I got the idea to thicken it up a little and turn it into an oatmeal mug muffin. After some adjustments with the ingredients and some cook times, they finally came out perfect. Now my family can have warm muffins for breakfast without having to bake a whole batch!
How to make an oatmeal mug muffin…
- Pour an instant oatmeal packet in a mug.
- Add flour (GF if necessary), sugar (optional), oil, baking powder, and water.
- Stir with a fork until a thick batter forms.
- Microwave on high for 2 minutes.
Pro Tip: You can even make up little baggies with the extra dry ingredients in them so all you need to do in the morning is pour in the dry ingredients, add water, and heat for 2 minutes. Take them to the office and eat a hot breakfast at your desk. They work great for a hot after school snack too!
Can they be made gluten-free?
Yes, it’s easy to make them gluten-free, simply use gluten-free flour and oatmeal. Any of the gluten-free flour mixes work well for this recipe, and since it is in a mug, it doesn’t matter if it is a little crumbly. If you need them to be 100% gluten-free, make sure to use gluten-free instant oats.
Note: Regular oatmeal can contain traces of gluten.
How do I make these oatmeal mug muffins healthier?
If you want it healthier, leave out the sugar and/or the oil. It comes out well without them too. You can stir in some flax meal too for some extra nutrients!
Throw in a tablespoon or raisins or blueberries to give it a twist. Apple cinnamon works well in this recipe with little chunks of oatmeal in the muffin. Try experimenting with different flavors of oatmeal. Let me know which flavor you like best!

Perfect recipe, and very forgiving! I typically use just the flour, baking soda, and replace the water with milk (any kind, including fat-free, vanilla almond, full-fat cow’s, etc). I have grated some carrots into it for a super lazy healthy carrot cake! It doubles well, same 2 minute cook time. Looking forward to further experimentation. Thanks 🙂
I’m so happy that you like it, Amber! Adding carrots is a brilliant idea! 🙂
I had old oatmeal packets leftover from a house guest and successfully made muffins using this recipe, thank you. I used no oil but instead 1/4 cup Asian soy milk in place of the milk, which did contain some fat. I will experiment with other flavors, maybe chocolate soy milk. The muffin itself did not stick to the mug but I had to soak it for a little while to release the crumbs. This would be nice while traveling since most hotels seem to have a microwave and mini fridge now and I could bring shelf stable milks. Thank you again.
You’re welcome! These do work great for traveling or college dorm food. When all you have is a mini-fridge and a microwave, this is a great breakfast or snack! 🙂
Can you turn this recipe into a cookie?
I have never tried it, but I think that you could by cutting the water in half and using 2 tbsp of water instead of 1/4 cup of water.
When you say 1 packet of instant oat can you specify this in terms of how many tablespoons.. The reason I am asking is because I have a large packet of oats from which I need to remove the amount required for this cake..
Thanks! Loved your recipe 😀
There are about 6 tbsp. of in 1 packet of instant oats. Hope that helps.
I love this mug muffin! It’s like magic to see oatmeal turn to a muffin in 2 minutes!
I’m so happy to hear that you like it Marie!
