Why you'll love this blueberry apple crumble
- Simple Jammy Fruit Filling: Fresh blueberries and apple pieces tossed in a simple mixture of sugar, cornstarch, lemon juice, salt, and vanilla create the most delicious jammy filling.
- Oatmeal Cookie-Like Crumble: The magic of combining brown sugar, butter, and oats is something we should never take for granted. And when paired with a juicy fruit filling?! It tastes equally as comforting & nostalgic as it does gourmet & unique.
- Ideal Make Ahead Dessert: The simplicity of this recipe makes it the perfect make ahead dessert! Assemble the crumbles in the morning and store them in the fridge. That night, about 45 minutes before you'd like to serve them, bake them and enjoy warm with a scoop of vanilla ice cream!
Ingredient Notes
- Fruit: You can use either frozen or fresh blueberries. You'll also need two baking apples. I prefer honeycrisp, but you can also use pink lady or Granny Smith.
- Cornstarch: This will help thicken the filling.
- Lemon: A touch of fresh lemon juice will brighten up the fruit filling.
- Flour: Use a high quality unbleached all purpose flour for best overall results.
- Butter: Be sure to use a high quality European-style butter! This type of butter has more fat content than American-style butter, and therefore provides the best flavor.
- Oats: Use old fashioned rolled oats for the best crumble texture!
- Cinnamon: I like to add a touch of cinnamon to the crumble topping for a bit of warmth, but feel free to add other warm spices, like nutmeg and allspice, or omit it altogether.

STEP 1: Make the crumble topping: In a medium bowl, combine the flour, oats, brown sugar, cinnamon, and salt. Add the cubed butter and toss to coat. Rub the mixture between your fingers until it resembles wet sand and there are no visible pieces of butter left. Cover the bowl and place in the fridge until ready to use.
STEP 2: Make the filling: In a large bowl, combine the apples, blueberries, sugar, cornstarch, salt, lemon juice, and vanilla.
STEP 3: Assemble. Divide the apple blueberry filling between 5 mini cocottes.
STEP 4: Bake. Top each with a generous amount of the oat crumble. Place the crumbles on a baking sheet, and bake for about 35-40 minutes or until the topping is golden brown and the juices are bubbling over.
Allow the crumbles to cool for a few minutes, then top each with vanilla ice cream and enjoy!
Expert Baking Tips
- Chill the crumble. Once you've made the crumble topping, place it in the fridge to let the butter firm up again before baking.
- Bake until filling is bubbling. To ensure the filling turns out jammy, be sure to let the crumbles bake until the juices are bubbling up over the cocottes.

Baking in Grams
All of the recipes on this blog are carefully developed with gram measurements so you can easily recreate them in your own kitchen with success. Volume measurements are extremely inaccurate and leave room for significant errors. Not all measuring cups are made equally, so your one cup of flour will be different from my one cup of flour. By providing precise measurements in grams (aside from minor ingredients, which are given in tsp/tbsp), you can make these recipes accurately and with less cleanup! All you need is this kitchen scale.
If this still isn't enough to convince you, I have provided volume measurements in the recipe card. If you are interested in understanding the conversions, this is the best conversion chart.
But trust me, once you try baking in grams you'll never turn back!
Happy baking! x
