It’s summertime as I write this post. The blueberries are coming off the bushes in bucketfuls. Berries, in general, are abundant in the Pacific Northwest, my neck of the woods.

But the beauty of this incredibly, surprisingly delicious dessert is that frozen blueberries are abundantly easy to find… any time of the year.

And if you love berries, chances are you’re a berry crisp lover as well. As am I. As is… my entire family.

While there’s nothing more delicious than an oven-baked crisp, sometimes I don’t want to turn on the oven. Sometimes I don’t want to wait 25 to 30 minutes. Sometimes… I just want something warm, and comforting, and cozy… even in the summer. Sometimes… I just want it quick.

This 2 Minute Blueberry Crisp in a Mug is my go-to, yummy solution.

What sort of mug should I use to make my Blueberry Crisp?

I prefer a shorter, broader mug. But it really makes no difference. Use what you have, but make sure it is microwave safe!

Will the size of my mug change how many blueberries I need?

While I’ve included a recipe below, the amount of berries will depend on the size of your mug. Add or reduce as your heart desires. You’ll want to fill your mug to the brim with blueberries, as they’ll shrink as they cook.

What type of Instant Oatmeal do you use?

I like to use Quaker’s Maple Brown Sugar or their Cinnamon and Spice flavor, but your favorite brand should work well as long as the flavors go with blueberries! If whatever you have in the house won’t work with blueberries but might work with apple, I also have a recipe for a 3 Minute Microwave Apple Crisp in a Mug!

You should remember though that the oatmeal topping is not going to taste exactly like what you expect when it’s baked in the oven. But’s it’s pretty delicious all the same. The texture is a bit crunchier. Some of the oat topping may sink to the bottom of the mug but is easily pulled up with your spoon.

Description

Learn how to make a delicious Blueberry Crisp in a Mug. With just 4 simple ingredients and just 2 minutes in the microwave this is a simple dessert recipe you’re going to love! And because you can use frozen berries, you can enjoy this quick summer crisp recipe all year long!


Ingredients

Units Scale
  • 1/2 packet of flavored instant oatmeal
  • 1 tablespoon butter, melted
  • 3/4 cup blueberries (fresh or frozen)
  • 1/2 teaspoon cornstarch (see note)

Instructions

  1. In a small bowl with a fork, mix the instant oatmeal and melted butter until it resembles a crumble topping.
  2. Add the fresh or frozen blueberries (if using frozen see note!) to the mug; toss with cornstarch if using. I like to fill my mug to the brim with berries, so the amount will vary depending on its size. Spread the topping over the top.
  3. Microwave on HIGH 1 1/2 minutes. This time will be dependant on your microwave wattage, the size of your mug and quantity of berries used. Continue to microwave in additional 30-second increments until the blueberries are bubbling.
  4. Let cool slightly before adding a scoop of vanilla ice cream, if liked. It’s so yummy!

Notes

Topping: 1 full packet of instant oatmeal is enough for 2 mugs.

Berries: If using frozen berries, allow an additional 15 to 30 seconds of cooking time.

Cornstarch: The cornstarch isn’t necessary but it does thicken the berries considerably, more similar to your favorite oven-baked blueberry crisp.

    1. Yay! Thank you for sharing that. It’s such an easy recipe, and perfect during the fresh blueberry season! Thank you for sharing!!

  1. This is a GREAT recipe and it comes at a good time health wise. Diagnosed with type 2 diabetes and mild fatty liver disease. Blueberries – good for both, Oatmeal – good for both, I used grass fed butter or olive oil for mixing the Brown Sugar & Maple Syrup oatmeal (low sugar variety) so I got good fat. Used Almond flour instead of cornstarch. I think adding either one makes it more filling but consider the almond flour to be a little more on the health side. I am considering adding some chopped pecans. Once you have made it a couple times you can get it done during a commercial break. I pick blueberries every season and I am going to have to increase the harvest.






    1. Thank you, Roger, for your kind words. I’m SO glad you enjoyed the recipe and are taking care of yourself! Blueberries are awesome and I LOVE your substitutions!

  2. My boyfriend and I adored this, thanks for sharing. We bought so much oatmeal during Covid 19 since it keeps and can be a good way to ration as it fills you up. Now we can turn those rations into something more fun and healthy. <3

  3. Great, simple recipe! Delicious and done so quick! Wish I would have found this years ago. Will make a really healthy breakfast on the go too.






  4. Yummy and perfect with a scoop of vanilla ice cream. I used Maple and brown sugar oatmeal and it was the perfect match.






    1. Thank you, Tory! I love this one too. It’s just SO easy!! Thanks for coming back and giving it a great rating!!

  5. This took me way more than 2 minutes to make this. Just melting the butter and making the crumble took more than a minute. Then measuring out and washing the blueberries added more time before the microwave for 1 1/2 minutes.
    It came out VERY hot and was bitter. We added a packet of stevia. There was no “crisp” so we topped it with a couple a Tbsp. of Alpen muesli. That made it crunchy and really quite good.






    1. So sorry, Bernadette. I love this recipe. However, cooking times vary with microwaves. If you try it again. mix the instant oats into the blueberries before cooking.

  6. Exactly what I was craving! Instead of a packet of oatmeal though I used regular rolled oats and a little bit of brown sugar.
