Gluten Free Pineapple Upside Down Mug Cake - 5 Minute EASY Breakfast!
I don’t know what’s better: a wholesome breakfast that tastes like dessert, or a microwaveable breakfast-in-a-mug?!
With this easy pineapple upside down mug cake recipe, you can have the best of both worlds!
You’ll satisfy your sweet tooth first thing in the morning—with a deliciously nutritious breakfast that only takes FIVE MINUTES to make. (Oh, and did I mention this is a gluten-free mug cake recipe?!)
Seriously, you just can’t beat breakfast mug cake recipes.
Because, let’s be real: mornings are BUSY.
Whether you’re rushing to work, headed to school, or just have things to do and places to be, there’s not always time to get in the kitchen and cook breakfast.
But, sometimes skipping breakfast comes back to bite us!
We might get hungry and cranky halfway through the morning (a.k.a ‘hangry’), and it’s tough to get through the day when the belly is rumbling. Or, we end up over-snacking and overdoing it later in the day!
Pineapple Upside Down Mug Cake, to the Rescue!
That’s where mug cake recipes come to the rescue.
Just mix your batter together, pour it into a mug, and pop it in the microwave!
Some mug cake recipes turn out dry and gummy, but this pineapple upside down mug cake has an unbelievably soft and springy texture—just like a freshly baked cake.
You’d never guess it was cooked in a microwave!
That’s because of the oat flour, which is much lighter and fluffier than traditional flour. And it’s gluten-free!
Plus, you can save a few bucks by tossing oats into a blender and making your own oat flour at home.
(For anyone with Celiac or a gluten sensitivity, be sure to choose certified gluten-free oats or oat flour!)
Or, you could make your pineapple upside down mug cake with coconut flour instead!
But, keep in mind that it’s denser than oat flour, so you’ll need to use less coconut flour than you would oat flour.
If You Like It, Put a Pineapple Ring On It
For all of the pineapple fans out there, this is totally the mug cake for you.
It’s made with pineapple chunks, pineapple juice, AND a pineapple ring on top, so you get that yummy tropical flavor in every bite.
Plus, pineapple upside down cake is truly the PERFECT mug cake recipe.
You can trim the pineapple ring to fit the bottom of your mug before pouring in your batter. Then, just microwave and flip your mug over onto a plate to reveal a steaming, gorgeous pineapple upside down MUG cake!

This says 50 carbs, can that be right? Is it the same if you use coconut flour?
Hi Janet, yes 50 carbs is correct! Some from the oat flour, some from the coconut sugar, and also natural sugars from the pineapple and pineapple juice.
If you use coconut flour, the total carb count will go down. The 1/3 cup of oat flour contains about 26g carbs and 4g fiber. Whereas 4 Tbsp of coconut flour would contain about 18g carbs and 10g fiber (so fewer net carbs overall as well). Just keep in mind, the texture of a microwave mug cake with coconut flour vs. oat flour may be slightly different - but still delicious!
Hi! This recipe looks delicious! Any chance that there is an oven/toaster over version?
Thanks for sharing your wonderful creations with us.
Hi Rebecca, so glad that you like the recipe! Unfortunately we haven't tried making this recipe in the toaster oven or standard oven, so I can't speak to how you might translate this recipe from the microwave to a different appliance.
It is possible to prepare mug cakes in a traditional oven, if you have an oven-safe mug and are willing to do a bit of experimenting. The general recommended temperature and cook time for an oven mug cake is 350°F (180°C) for 15-25 minutes. Again, I can't speak to how this would work with this specific pineapple upside down mug cake recipe, but you can give it a try - just be sure to monitor as it bakes until you've got a sense for how long it needs in your oven! Hope this helps 🙂
Can we use honey instead of coconut sugar, and use it as the sweetener in the recipe
