Move over mug cake, there’s a new favorite mug-made dessert in town! Guys, guys, guys… I am so in love with this Cinnamon Apple Crisp in a Mug recipe! It’s so good and SO freaking easy to make. We’re talking 6 ingredients plus dairy-free vanilla ice cream on top, and less than 10 minutes of your time before you get to dig in!

My daughter and I got to go to the apple orchard recently with her preschool class, so of course we came home with bags of apples begging to be used in our favorite apple desserts. I wanted to create something quick and easy that we could make together with the apples we picked, and wow, this apple crisp was the perfect choice.
Last year when we went to the apple orchard I made my Naturally Sweetened Instant Pot Apple Butter and Golden Delicious Cinnamon Applesauce! They both turned out amazing, so if you have a ton of apples, definitely check those recipes out.

The Steps
All you have to do is combine the crisp later which consists of gluten-free old fashioned oats, oat flour, coconut sugar (or brown sugar), cinnamon, nutmeg, and vegan butter in a bowl. In a separate bowl, stir together 1 diced apple with coconut sugar (or brown sugar), cinnamon, oat flour, and vegan butter.
Place half of the apples in the bottom of the mug, top with half of the oat mixture, add the remaining apples, and then top with the remaining oat layer. Then microwave for 4 minutes. Let it cool slightly, top with dairy-free vanilla ice cream and voila! Done! See?! I told you it was simple 😉

Modifications
I chose these 6 ingredients because they repeat in the two layers, and they’re readily available pretty much everywhere.
If you don’t have oat flour you can simply grind the oats into flour.
If you don’t want to use butter, you can use coconut oil instead.
Sugar/sugar substitutes that work in this recipe 1:1 are coconut sugar, maple sugar, maple syrup, brown sugar, brown sugar replacement (like Swerve).

This Cinnamon Apple Crisp in a Mug recipe will serve 1, so if you’re making a couple of mugs worth, simply double or repeat the recipe per mug.
I hope you can get out to a local apple orchard and go apple picking this Fall! There’s just something magical about picking your own apples and then coming home and making all of the delicious desserts 🙂
