⭐Why I Love It:
- Single Serve Dessert - Perfect when you want a sweet treat, without making a whole dessert. For a single serve fruit crisp made in the oven, try this Single Serve Apple Crisp or Single Serve Blueberry Crisp! Or if you're craving an apple pie, I love this Individual Apple Pie!
- Ready in 5 Minutes - This apple crisp in a mug doesn't get any quicker to make!
- Tender Apples and Crunchy Topping - The combination of soft, tender apples and the crispy oat topping can't be beat!
🥘Ingredients and Equipment:
- Apple - I prefer to use a baking apple like Granny Smith, but you can use any apple for this recipe. If you have more apples, try making this Apple Dutch Baby Pancake for breakfast.
- Ground Cinnamon
- Ground Nutmeg - optional, but I like the extra flavor it adds
- Brown Sugar - light or dark brown sugar work
- Butter - you can use salted or unsalted butter
- All-Purpose Flour
- Classic Rolled Oats - Oats in the topping are what makes a 'crisp' a crisp! A crumble does not have oats in the topping.
- Microwave-Safe Mug - Use a standard size (8oz or larger) microwave safe mug. If you don't have a mug, you can use another microwave-safe dish to cook.
- Peeler - I like to peel the apple. If you don't have a peeler, you can carefully use a sharp knife to remove the apple skin or you can leave the skin on if you don't mind the texture.

🔪Step by Step Instructions:
It takes only 5 minutes to make a warm individual apple crisp in a mug!
Photo 1 - Peel and chop up the apple into small pieces. The smaller the pieces, the more tender they will be. If you like your apples to have more of a bite, then cut them a little larger.
Photo 2 - Add apples to microwave safe mug and toss with cinnamon, nutmeg, and brown sugar (if using). In a small bowl, melt the butter. Mix the melted butter with brown sugar, flour, oats, cinnamon, and nutmeg. Top the apples with the oat crumble mixture.
Photo 3 - Microwave the mug for 2 - 2 ½ minutes. The apples should be tender and the crisp topping should be bubbling.
Photo 4 - Allow to cool for a few minutes and enjoy!
💭Recipe Tips:
- Cook Time Varies - Microwaves have different strengths which will impact the cook time. I recommend you check the crisp after about 1.5 minutes then add more time, as needed. If you make it in a more shallow dish vs the mug, then it will also cook faster.
- Apple Pieces Size - If you want your apples to have more of a 'bite' then cut the pieces larger. If you want them super soft, then cut them smaller.
👩🍳Recipe FAQs
Any standard size (8 ounces or larger) coffee mug works! This apple crisp will cook down as the apples cook, so it's okay if the recipe fills up to the brim of your mug. Unlike other mug cakes, this one does not rise and expand as it cooks. The most important piece is to use a mug that is microwave safe!
Because you eat the crisp right out of the mug, you do not need to grease. Although, if you want easier clean up you could spray with cooking spray before cooking. I do not grease and instead just soak the mug in some warm soapy water for a few minutes before cleaning to remove any cooked on bits.
This recipe is written for one apple crisp, but you can easily double it to make two! You can chop up two apples and divide between two mugs. You can do the same with the crumble topping - mix up a double batch and divide between the two mugs. It’s best to microwave them separately, though.
