Easy mini blueberry plum crumbles. These delicious crumbles combine sweet and juicy berries and plums with cozy cinnamon and cardamom and a buttery brown sugar oat crumb topping. Simple to make, full of complex flavor, and perfect for Summer/early-Fall baking. Easily adaptable, gluten free and vegan friendly.



Blueberry Plum Filling

Oat Crumble Topping

  • 1/2 cup (45g) rolled oats
  • 1/4 cup (30g) all-purpose flour ²
  • 1/4 cup (50g) light brown sugar, packed
  • pinch fine sea salt
  • 3 Tbsp (43g) unsalted butter, softened ³


  1. Preheat the oven to 375℉. Lightly grease 4 mini ramekins with butter or baking spray. Set aside.
  2. In a medium mixing bowl, toss together the plum slices, blueberries, sugar, spices, and arrowroot starch, if using. Set aside.
  3. Make the crumble topping: In a small mixing bowl, stir together the oats, flour, brown sugar, and salt until combined.
  4. Add the butter, and use a pastry blender or your fingers to cut the butter into the dry ingredients. Continue until the butter is completely incorporated, and the mixture comes together into a chunky crumb.
  5. Divide the blueberry-plum mixture between the prepared ramekins. Top with the crumble topping and bake for 25-30 minutes, until the crumble topping is golden brown and the berry juices begin to bubble.
  6. Remove from the oven and let cool for 5 minutes. Serve warm a scoop of vanilla ice cream. Enjoy!!


¹ Arrowroot starch is my favorite pie and fruit filling thickener. It creates a smooth, shiny sauce without a noticeable added taste. As a second choice, you can also substitute (blended) instant tapioca pearls or cornstarch. Or, omit the starch, and enjoy a saucier crumble!

² Make these crumbles gluten free by substituting all-purpose gluten free flour and making sure your rolled oats are also GF Almond or oat flour would likely work as well.

³ Make them vegan by using vegan butter (such as Earth Balance buttery baking sticks), or room-temperature unrefined coconut oil.
