I am obsessed with making healthier for you treats. This Chocolate Oat Flour Mug Cake with Olive Oil (Vegan) is the perfect healthy treat.
This mug cake tastes like a brownie, it is so freakin good. Thanks to oat flour it is also gluten free.
I love making healthy single serving desserts. For another yummy single serve dessert try my single serve cookie or my apple pie shaved ice.

Instructions for making chocolate oat flour mug cake

Step 1: Mix together all ingredients except for chocolate chips until smooth.

Step 2: Top with chocolate chips.

Step 3: Microwave
Substitutions
- Olive oil - can be subbed with coconut oil or another neutral oil
- Coconut sugar - can be subbed with brown or white sugar
- Cacao - can be subbed with cocoa powder
- Oat flour - this can probably be subbed for all purpose flour, but I do not recommend
Equipment
No special equipment needed here. However I do love using these ramekins for my mug cakes.
Storage instructions for single serve brownie mug cake
Although this only makes one serving, you could technically make this mug cake ahead of time and store it in a covered ramekin or mug for up to 24 or so hours.

THIS IS SO GOOD. I have a hard time finding good mug cake recipes and this was by far my favorite. Moist, chocolatey, great texture.

This recipe was luscious! I added hersheys kisses in the middle and subbed applesauce for the oil. Also added a sprinkle of espresso powder. Will make again and again!

Honestly it came out fairly well.
I nuked it for 60sec but I think a little longer would have been better.
Over all it was a yummy and simple treat.
