How to make blueberry crisp in the microwave
Making this dessert in the microwave is SUPER easy. The full instructions with exact measurements are in the recipe card at the bottom of this post. But here's an overview:
Step 1 - In a small microwave-safe bowl, mix the blueberries with cornstarch. Microwave for two minutes. Watch it toward the end to make sure the blueberries don't "pop" - if they start to, it's time to take the bowl out of the microwave.
Step 2 - In a separate bowl, mix together the remaining ingredients. Then place on top of the blueberries.
Step 3 - Microwave for one minute. Stir, then microwave for one more minute. Allow the bowl to sit at room temperature for a minute before diving in and devouring this delicious, fast and easy dessert!
What's so great about blueberries?
Blueberries are known as one of the "superfoods" that pack a wealth of health benefits in each serving. They are packed with antioxidants and phytoflavinoids, Vitamin C, and potassium. Blueberries may help lower your risk of heart disease can cancer. They are also anti-inflammatory, and may help lower blood pressure.
According to Science Daily: "Eating a cup of blueberries a day reduces risk factors for cardiovascular disease... Eating 150g of blueberries daily reduces the risk of cardiovascular disease by up to 15 percent."
Both are equally nutritious and delicious! Frozen berries are usually flash frozen immediately after they are picked at peak ripeness. Studies have shown that there is no loss of antioxidants in blueberries that have been frozen for up to five months (source: science daily).
Try this same recipe using apples, pears, peaches, blackberries, raspberries, strawberries, or marionberries. A triple berry crisp would be amazing!
If you are dairy-free like me, you can substitute your favorite vegan butter for the regular butter in this recipe.

This was amazing!!! Didn’t have corn starch on hand and it was perfect even without. I topped it with ice cream. Delicious treat after both my kids went to sleep 😂

Loved how easy this crisp was to make! Will definitely come in handy for quick, single servings.
I hear you on that needing something sweet, but no time. I love how this just takes a few minutes in the microwave. Yum!
Such a fun and easy summertime dessert! I love the single serving size and how it comes together in the microwave. A triple berry version does sound amazing too!

I just love single serving dessert ideas like this! And I love that it is made in the microwave. :)
You've just made my kids very happy! They love fruit crumbles but I don't always have the time to make them. I made this with frozen raspberries (I was out of blueberries) and it was amazing!
