Healthy Pineapple Upside Down Mug Cake
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 get the best of both worlds.
A Gluten Free Breakfast Mug Cake!?
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! That’s where mug cake recipes come to the rescue.
Pineapple Upside Down Mug Cake Ingredients
- Egg. Eggs are a binder
- Coconut oil.
- Vanilla extract.
- Almond milk. I used almond milk in this recipe, but you can use any milk you prefer!
- Pineapple juice. Yes, you cannot have pineapple upside down without pineapple juice in my opinion! It not only adds a more complex sweetness than regular sugar, it also amps up that fresh pineapple flavor!
- Oat flour. Oat flour is much lighter and fluffier than traditional flour, and it’s naturally gluten free! For anyone with Celiac or a gluten sensitivity, be sure to choose certified gluten-free oats or oat flour. Plus, you can save a few bucks by tossing oats into a blender and making your own oat flour at home.
- Baking powder.
- Pineapple. Diced pineapple along with a pineapple ring on the bottom make this mug cake feel so much like a classic pineapple upside down cake.

Once it’s cooked, flip your mug over onto a plate to reveal a steaming, gorgeous, microwave pineapple upside down cake.
What flour to use in a gluten free mug cake?
Some mug cake recipes turn out dry and gummy, especially if they’re gluten free. 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 naturally gluten free! For anyone with Celiac or a gluten sensitivity, be sure to choose certified gluten-free oats or oat flour. Plus, you can save a few bucks by tossing oats into a blender and making your own oat flour at home.
If desired, you could also make this breakfast mug cake with coconut flour instead. Just keep in mind that coconut flour is denser than oat flour, so you’ll need to use less coconut flour than you would oat flour (1/4 cup vs. 1/3 cup).
