Microwave Apple Crisp

Pumpkin gets a ton of love this time of year, but I’ve tried to make it a point to show some love to the not-so-famous fall staple, apples. This love recently came in the form of a Apple Crisp Pie that will rock you to your core. But my goal with Mugs for Muscles is to provide quick and easy recipes, and this microwave apple crisp is just that.

In about five minutes, you’ll have a 146-calorie apple crisp that’s the perfect vehicle for ice cream, Greek yogurt, whipped cream, or anything else you throw at it. You’ll only need five ingredients other than an apple, and I’ll briefly run through them below to give you ideas for modifying as needed.

A 146-calorie microwave apple crisp recipe that transform a fresh apple into a deliciously sweet treat in about five minutes.

Microwave Apple Crisp Ingredients

First and foremost, feel free to use any apple you’d like. I opted for a Fuji apple because they tend to work well as a baking apple. And while this apple crisp is microwaved, it can’t hurt.

As for the apple peel, I tested recipes with the peel on and off. I like both, but the recipe calls for peeling the apple.

Walden Farms Pancake Syrup

I don’t love many of their products, but the pancake syrup and most of the flavored pancake syrups are great. If you don’t have access to Walden Farms, any sugar free pancake syrup will do here. Also, you’ll only need two tablespoons so using regular pancake syrup or maple syrup won’t add that many calories.

Apple Crisp Topping

Here’s everything you’ll need along with a quick note on modifying:

  • quick oats – any type of oats will work but may affect cook time slightly
  • graham cracker crumbs – more info in the recipe card below on alternatives
  • light butter – unsweetened apple sauce may work but the crisp will be softer
  • apple pie spice – a mix of cinnamon, nutmeg, ginger, allspice, and a few other spices (cinnamon works fine)

If you have the calories to spare, I recommend adding chopped pecans or some type of nuts to the mix. The apple crisp pie I mentioned above uses pecan pieces and no graham cracker crumbs.

This is so simple and delicious! I would recommend adding a little lemon juice to make it a little less sweet if you would like! Awesome snack!

It tasted GREAT, but it didn't turn out crispy.

Delicious! I made a couple changes... 1) I am VERY allergic to wheat, Over the years I've started using Honey Nut Cheerios for a good substitute for graham crackers in most recipes. 2) I detest "sugar free" almost anything. But I buy "light" whenever possible, such as pancake syrup. Why have 100 calories when I cannot tell any difference in the 50 calorie version? With these changes I get this at 206 calories. Still a very acceptable amount for such a tasty treat!

I bought a bunch of apples at Costco, and then I saw apple crisp on a cooking show, so naturally I had to see if Mason had an individual apple crisp recipe. The only change I made the first time around was to use Walden Farms caramel sauce instead of pancake syrup. I make this at least once a week now, but I triple the amount of oats and sub chopped nuts instead of graham cracker crumbs. One of my favorite desserts!

This is so easy to make and delicious! It will be my go to from now on to curb my sweet tooth. I didn’t have apple pie spice so i used cinnamon and it was perfect! Tastes just like apple pie! Live to top it with a bit of vanilla halo top top if I have the macros available!
