I love apple crisp.  In fact, my Apple Crisp Recipe is one of my favorite desserts on my blog.  I cut the recipe from our local newspaper back when I was in high school.  It’s the best I have ever found.  But sometimes, I’d like to enjoy it, and I don’t really have a need for a whole 9×13 pan of it.  Ya know?  Like, trust me, I could certainly put a big dent in a 9×13 pan of apple crisp, but do I need to?  Not so much.  

That’s when this apple crisp in a mug is perfect.  In a matter of minutes you can be enjoying a warm apple crisp, topped with vanilla ice cream, right from the mug you cooked it in.  Can you imagine the looks you’d get eaten from the 9×13?? No judgement with the mug!

Apple Pie Oatmeal Cookies

This is my second recipe this week for our #AppleWeek event.  It was hard to decide what to share with you first,  but I shared my Apple Pie Oatmeal Cookies with you on Monday, and saved this microwaved mug apple crisp with you today.  It’s perfect for a little mid-week snack, don’t you think?   



It’s meant to be a dessert for one, but of course also makes a fun date night in dessert with two spoons. (or if you want — double the batch and make two – one for each of you!)


Speaking of making multiples, this makes for a fun dessert for parties, too, because you can make them ahead, and microwave them when you’re ready for dessert.  Then you can have a mug in each hand! One with apple crisp and the other with coffee.  #winning  



Coconut Mug Cake

I have made a couple of recipes in a mug.  Way back when I made these Hot Chocolate Cupcakes in Mason Jar Mugs — I did them as teacher’s gifts.  More recently though, I made Coconut Mug Cakes, and next to coffee,  and this Peanut Butter Hot Chocolate, it was my favorite thing to come out of a mug in ages!


What do I need to make Apple Crisp in a Mug in the Microwave?

  • medium sized apple
  • flour
  • sugar
  • cinnamon
  • butter
  • rolled oats


You’re going to need to select an apple that is medium in size.  This shows how it fits in my hand.  

You can use any kind of apple that you enjoy.  I like my apples to be a little more on the tart side for baking.  For pies I typically use Granny Smith.  


Selecting and Storing Apples: 

When you selecting apples, find fruit that is firm and bright colored, free of blemishes and bruising.  Gently press fruit to ensure that it is not soft or dents easily.  Store your apples in the refrigerator, but make sure not to put close to other produce, as apples are known to absorb the odors from other produce.  You don’t want your apples smelling like onions! Make sure to always wash your apples in cool running water to make sure they are free of dirt and bacteria.


When I cut into an apple it turns brown so quickly.  How do I alleviate that?

Apples turn brown because of polyphenol oxidase enzymes.  Some varieties brown even faster than others.  You can slow down the browning by tossing them in a solution containing citric acid, like lemon juice or even lemon lime soda.  



Coat a mug, that is about 12 ounces,  in size with non-stick cooking spray.  Peel and dice your apple.


Then prepare your apples with cinnamon, sugar and flour, and add them to the mug. 


Mix up your oatmeal crumb topping by combining your rolled oats, sugar, flour, cinnamon and butter.  Add to the top of the apples.  

It looks really full, but it cooks down.


This is what it looks like after you microwave it.  Be super careful.  It’s HOT!!  


Let it sit for a minute or two then give it a stir with a fork.  The apples are tender and spiced perfectly.  The oatmeal topping is crunchy and warm.  


It only gets better when you top it with a scoop of vanilla ice cream and it melts right in.  Mmmm.

Baking with apples is always one of my favorite ways to bake.  Fall baking in general, but apples especially.  I know everyone goes all pumpkin spice crazy, and don’t get me wrong, I like pumpkin as much as the next girl, but I think that apple season gets shortened because of it! 

September, to me, is Apple Season.
