A Blueberry Crumble is similar to Blueberry Cobbler. A Blueberry Cobbler is topped with dollops of batter or biscuit dough while a Blueberry Crumble is topped with streusel crumb topping.

    This was yummy! I really like that it is a small quantity. I made it in my toaster oven. I only used 1 tablespoon of sugar in the blueberries and it was plenty. There was plenty of topping. I think I will halve the topping amounts next time but that is just personal preference and an excuse to eat it with ice cream. Thank you for the delicious and easy recipe 🙂

    Delicious! Used frozen berries and applesauce instead of butter for the crumble. And extra lemon juice in filling. And Splenda instead of brown sugar. Thanks!

    I made half of the recipe which was just enough for myself and baked it in a toaster oven. It’s the best blueberry crumble I’ve ever had and it’s so easy! I 100% recommend others to make this!

  4. Any thoughts on doubling or even tripling the topping part of the recipe, without the butter, and storing it to use again for the next crisp or crumble, then just adding in the butter when you need topping for the next time. I thought this blueberry crumble was sensational, and would try it with other fruit as well. Love your recipes. Thanks for taking the time to take the work out of adapting favorite dishes for the rest of us.

    1. Hi Susan,

      I’m so happy you loved the blueberry crumble, thank you for taking the time to let me know!

      Yes, you can definitely double and triple the dry ingredients in the streusel – just leave out the butter and add it when you decided to use the topping.


  5. I don’t usually leave comments when I try a new recipe, but I just made this and it is delicious! I did motify it a little though. I used frozen blueberries and cherries. I used honey instead of sugar for the fruit and added some cinnamon. I also used Kerrygold salted butter for the topping. Sweet and a little salty!!! It is very tasty!

    1. I’m so happy you enjoyed the recipe, Wendy. Thank you for sharing your changes to the recipe and I’m so glad they worked for you.
      Have a wonderful week.
