Mini blueberry crumble made with a handful of blueberries and a crisp oat topping. A wonderful single serving dessert! Quick, easy, and so delicious!
Why I Love This Recipe
- A blueberry crumble is similar to blueberry cobbler. A cobbler is topped with dollops of batter or biscuit dough while a crumble is topped with streusel crumb topping.
- This single serving crumble is easier to make than pie. The berries are mixed with a little sugar, flour, and a touch of lemon juice which helps to create the filling. There isn't a crust to make, instead the blueberries are topped with a sweet, crunchy topping.
- I think a blueberry crumble is best when it's warm from the oven. Add a scoop of vanilla ice cream and you'll be in dessert heaven!
- This dessert is made with pantry staples. No fancy ingredients are even necessary.

Ingredient Notes
- Blueberries: Use fresh or frozen and thawed blueberries.
- Sugars: A small amount of granulated sugar is all you need for the filling and brown sugar is used in the topping.
- Flour: You can use all-purpose flour or a gluten-free flour.
- Lemon juice: Use freshly squeezed or bottled lemon juice. Lemon juice brightens the flavor and cuts the sweetness.
- Butter: Softened butter is used to make the topping. Softened butter should still be cool to the touch but when you press your finger into the butter, your finger will leave an indentation.
- Oats: For best results use old-fashioned oats (also called rolled oats).
- Salt and Vanilla extract: For flavor
- Vanilla ice cream or whipped cream: Optional, for topping the blueberry crumble.
How To Make This Recipe
- Take a half a pint of blueberries (roughly 6 ounces) and gently mix in a little sugar, flour, lemon juice, and a pinch of salt.
- Spoon the sweetened blueberries into a small baking dish then mix together the ingredients for the crumble topping.
- Bake the blueberry crumble in the oven for about 25 minutes. The mini dessert is perfect for one or maybe even two people.
Expert Tips
- Look for plump, smooth-skinned blueberries. Choose berries that are deep purple/blue. You can use fresh or frozen and thawed blueberries in this recipe.
- Consider using mixed berries. This recipe is very versatile, it is delicious with raspberries, blackberries, or a combination of both.
- Be sure to taste the berries before using them in this recipe. If they are tart, you might need to add a bit more sugar to balance the flavor.
Frequently Asked Questions
The best way to soften your butter is to put it out on the kitchen counter for a half hour before you want to use it. Another way to quickly soften butter is to put the cold butter in the microwave for 10 to 15 seconds. If you use this method, be sure to watch carefully - you don't want the butter to melt at all.
For this crumble recipe, I use a 5-inch dish or a ramekin that holds around one cup. For best results, use a dish of similar size.

Yum I followed the recipe exactly and it was delicious!
Muriel manley says
Could you use rhubarb instead of blueberries
Joanie Zisk says
You can, Muriel. You might need to bake the crumble a bit longer though. Check for readiness after 25 minutes and continue baking and checking at about 5 minute intervals until completely done.

Camelot says
I just made this blueberry crumble, and it was amazing. I followed the recipe exactly as written, do Please do NOT substitute butter ! Listen to Joanie, she has perfected these one dish servings.
It was perfectly balanced, not to sweet , right amount of crumbs to berries and delicious crispy top. By the way I just purchased the mini Breville oven for my 16 year old daughter . And that is what I used to bake this in, came out great. Next is the oatmeal cookies.
