Should I use quick or rolled oats?

I use quick oats in this recipe, but it also works well with thick rolled oats! The only difference is that quick oats are chopped into smaller pieces and thus absorb more liquid quicker, whereas rolled oats are larger and denser, giving the mug cake more chew. They both work, so just choose what you prefer!

Do I have to use a mug?

No! You can use any microwavable bowl or mug. Using a mug just makes it feel more cozy πŸ™‚

Use dairy free milk to make it vegan & dairy free

Changing the type of milk should not change the texture of the mug cake. Use any type of dairy free milk you’d like!

Use gluten free oats and flour to make this gluten free

I recommend using a gluten free flour such as GF all-purpose if you don’t want to adjust the recipe at all. Using oat flour should work as well, just keep in mind you will get a slightly less fluffy texture. I do not recommend using almond flour for this recipe (you’d have to adjust the proportions).

Add in chocolate chips and/or nuts if you’d like!

I personally never make this recipe without chocolate chips (nor do I ever make banana bread without chocolate chips…), but that’s just my preference! You can also add in chopped nuts or seeds to add a bit of a crunch.
