Ingredients

Scale
  • 6–8 ripe plums, pitted and sliced
  • 1/4 cup granulated sugar
  • 1 tsp fresh lemon juice
  • 1 tbsp cornstarch
  • 1/2 tsp ground cinnamon (optional)
  • 3/4 cup rolled oats
  • 1/2 cup all-purpose flour (or almond flour for gluten-free)
  • 1/2 cup packed light brown sugar
  • 1/4 tsp salt
  • 1/2 tsp ground cinnamon
  • 6 tbsp unsalted butter, cold and cut into small cubes (or vegan butter)
  • 2 cups whole milk (or dairy-free milk like oat milk)
  • 1/2 cup heavy cream
  • 4 large egg yolks
  • 1/3 cup granulated sugar
  • 1 tbsp cornstarch
  • 1 tsp pure vanilla extract

Instructions

  1. Preheat the oven to 350°F (175°C). Lightly grease your baking dish with butter or non-stick spray.
  2. In a medium bowl, toss the sliced plums with granulated sugar, lemon juice, cornstarch, and cinnamon. Set aside for about 10 minutes to macerate.
  3. In another bowl, combine rolled oats, flour, brown sugar, salt, and cinnamon. Add cold cubed butter and cut into the dry ingredients using a pastry cutter or forks until mixture resembles coarse crumbs.
  4. Pour the plum mixture into the prepared baking dish and spread evenly. Sprinkle the oat topping over the plums in an even layer.
  5. Bake for 35-40 minutes until the topping is golden brown and the fruit is bubbling around the edges.
  6. While baking, heat milk and cream in a saucepan over medium heat until just simmering.
  7. In a separate bowl, whisk egg yolks, sugar, and cornstarch until smooth.
  8. Temper the eggs by slowly pouring about 1/3 cup of hot milk mixture into the yolks while whisking constantly, then pour the yolk mixture back into the saucepan.
  9. Cook custard over medium heat, stirring constantly until thickened and coats the back of a spoon (5-7 minutes). Remove from heat and stir in vanilla extract. Strain if desired and let cool slightly.
  10. Serve the warm crumble with a generous pour of vanilla custard.

Notes

Use cold butter for the topping to achieve a tender, crumbly texture. Adjust sugar based on plum sweetness. Temper eggs slowly to avoid curdling custard. Cover crumble with foil if topping browns too fast. Can prepare filling and topping ahead and refrigerate separately.
