Blueberry Crumble For One

Making a warm and bubbly blueberry crumble is one of the easiest and most delicious desserts you can make. It’s rustic and elegant at the same time and can be enjoyed with a scoop of vanilla ice cream or a dollop of whipped cream, but we think this blueberry crumble absolutely perfect as-is, no topping required.

Why I Love This Recipe

• It tastes incredible! This mini blueberry crumble is filled with juicy blueberries and topped with a buttery oat topping. Enjoy as a dessert or as an indulgent breakfast treat.
• It’s easy to prepare: A 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. Pour the berries into a small baking dish and spoon over the oat topping – no crust needed!
• Perfect for using a small amount of blueberries: When you find yourself with about ½-pint of blueberries, this single serving dessert is the perfect one to make. If you want to use more blueberries, go right ahead. This crumble recipe doubles well, simply double the ingredient amounts and use a larger baking dish.

What Is The Difference Between A Crumble And A Crisp?

Deciding whether to call this a blueberry crumble or a blueberry crisp was a bit tricky. Both desserts are similar with very minor differences between them. In the end, I suppose it doesn’t really matter what we call it, it only matters that you make it because it’s so incredibly delicious and we know you’re going to love it too!

Crumbles and crisps are both baked desserts with some kind of topping. The differences can be confusing and depending upon what part of the country you live in, their names can be interchangeable.

Crisps and crumbles are incredibly alike and the differences between them can be argued depending on who you ask. Essentially, with a fruit crisp, the topping that sits on the baked fruit is crispy and crumbly. The topping contains butter and sugar and often flour and/or oats to help bind the ingredients together.

A crumble is essentially a crisp but it can have a slightly different texture. Some will add chopped nuts and warm spices like nutmeg or cinnamon.

Since the topping for our blueberry dessert is crumbly, we chose to call it a blueberry crumble.

Ingredients

Ingredient Notes

• Blueberries: My preference is to use fresh blueberries but if you have frozen blueberries, you can definitely make this dessert with those. Just be sure to thaw the blueberries first.
• Sugars: I like using a small amount of granulated sugar in the filling and also in the topping. We also add brown sugar to the crumble topping.
• Flour: Use all-purpose 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).
• Saltand Vanilla extract: For wonderful flavor
• Vanilla ice cream or whipped cream: Optional, for topping the blueberry crumble.

Expert Tips

• Make a gluten-free blueberry crumble: If you want to make a gluten-free version of this dessert, use your favorite gluten-free flour blend instead of all-purpose flour.
• 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.
• Reduce the sugar: The amount of sugar needed depends on how tart or sweet your blueberries are. 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. If the berries are sweet, feel free to reduce the amount of sugar you use.

Frequently Asked Questions

How Do I Soften Butter?

The best way to soften your butter for the crumble topping 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.

What Size Baking Dish Should I Use?

For this small blueberry crumble recipe, we use a 4×6-inch baking dish that has a base area of 24 square inches.

Other alternative baking dishes:
5×5-inch dish
6×6-inch dish (this size will yield a thinner blueberry filling, less crumble topping, and it may bake faster).
6-inch round dish

These baking dishes can be viewed on our Store page.

Can I Use A Different Topping?

You might like to try our blueberry cobbler recipe. The topping is more like a cake or biscuit.

Can I Make This Dessert Ahead?

Yes. Blueberry crumble will keep well in the refrigerator for up to 5 days and can be frozen for up to 1 month. I prefer to freeze the crumble topping separately and add it as a topping right before baking.

Crumble topping freezes very well and can be kept on hand to make any kind of fruit crumble.

To bake frozen blueberry crumble, simply bake from frozen until the filling is bubbly and the topping is golden brown.
