Blueberry Crisp in a Mug– 3+ ingredients, 2+ minutes, a microwave, and a simple recipe you’re going to love! A quick and easy comfort food filled with berries, ready in minutes, will have you enjoying the flavors of summer… all year long. 

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.

The Mug

Begin with a microwavable mug. I prefer a shorter, broader mug. But it really makes no difference. Use what you have.

Secondly, while I’ve included a recipe below, the amount of berries depend on the size of your mug. Add or reduce as your heart desires.

Here’s How it Works

Add fresh or frozen blueberries to your mug. I fill the mug to the brim because it shrinks as it cooks in the microwave. Toss the berries with some cornstarch to thicken. Not completely necessary, but I like the texture.

The topping is incredibly simple. I take one packet of my favorite flavored instant oatmeal and I mix it with some melted butter. It makes enough for 2 mugs. Ideas of flavored Instant Oatmeal that work well with this blueberry crisp are– Quaker’s Maple Brown Sugar, and Cinnamon and Spice.

Something to Remember

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.

And Finally…

Topping this warm comfort food dessert with a scoop of vanilla ice cream is more decadently delicious than I can describe.

You are two-plus minutes away from an incredibly delicious Blueberry Crisp!

2 Minute Blueberry Crisp in a Mug

  • Total Time: 4 minutes
  • Yield: 1 mug 1x
  • Category: Dessert
  • Method: Microwave


Blueberry Crisp in a Mug– 3+ ingredients, 2+ minutes, a microwave, and a simple recipe you’re going to love! A quick and easy comfort food filled with berries, ready in minutes, will have you enjoying the flavors of summer… all year long. 



1/2 packet of flavored instant oatmeal (like Quaker’s Maple Brown Sugar or Cinnamon and Sugar)
1 tablespoon butter, melted
3/4 cup blueberries (fresh or frozen)
1/2 teaspoon cornstarch (to thicken – see note)


In a small bowl with a fork, mix the instant oatmeal and melted butter until it resembles a crumble topping.

Add 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.

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.

Let cool slightly — add a spoon — enjoy. Or — add a scoop of vanilla ice cream. It’s so yummy.


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.

Keywords: blueberry crisp, microwave, blueberries, quick and easy dessert

    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!

    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

    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.

    1. I’m so glad you liked it, Kelsey! It’s such a great breakfast — or treat!!

  4. Jerri

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

    1. So glad you like it, Jerri! Ice cream is a must! ??

  5. Tory

    Yum!! Quick and easy treat!! I used the whole oatmeal/butter mixture 🙂

    1. Stephanie Wilson

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

    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.

    A little disappointing. The oats tasted raw.

    1. Stephanie Wilson

      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.

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

    1. Stephanie Wilson

      That sounds great! I will have to try that as well!
