Plum Crisp
Ingredients
- 2 1/2 pounds plums – pitted and sliced (~18.5 medium plums)
- 1/2 cup granulated sugar (100g)
- 2 tbsp cornstarch (16g)
- 1 tbsp lemon juice
- 1/4 tsp fine salt
- 3/4 cup all-purpose flour (90g)
- 3/4 cup old-fashioned rolled oats
- 1/2 cup light brown sugar – packed
- 1 tsp ground cinnamon
- 1/4 tsp fine salt
- 8 tbsp unsalted butter – cold, cut into small cubes

Instructions
- 1.
Heat the oven to 375°F (190°C) with a rack in the center.
- 2.
Pit and slice the plums into 0.5-inch wedges.
- 3.
In a large bowl, toss the plums with the granulated sugar, cornstarch, lemon juice, and 0.25 tsp fine salt until evenly coated. Let sit 10 minutes to draw out juices.
- 4.
Scrape the plum mixture and all juices into a 2-quart baking dish (about 9-inch square) and spread into an even layer.
- 5.
In a separate bowl, whisk together the flour, oats, brown sugar, cinnamon, and the remaining 0.25 tsp fine salt.
- 6.
Add the cold, cubed butter to the dry mixture. Use your fingers or a pastry cutter to work it in until the mixture forms moist crumbs that hold together when squeezed.
- 7.
Crumble the topping evenly over the plums, breaking up any very large clumps.
- 8.
Bake until the fruit is bubbling in the center and the topping is deeply golden, 40–50 minutes. If the topping browns too quickly, tent loosely with foil.
- 9.
Cool on a rack for at least 15 minutes to allow the juices to thicken, then serve warm (plain or with ice cream or lightly sweetened whipped cream).
Plum crisp is a cozy fruit dessert that pairs jammy, tart-sweet plums with a crunchy, buttery oat topping. The contrast of soft, syrupy fruit and nubbly, cinnamon-scented crumbs makes it as comforting as it is texturally satisfying. Served warm with its bubbling juices and crisp lid, it hits a balance of bright acidity and caramel notes that appeals to both fruit lovers and dessert traditionalists.
Crisps emerged as a homey, economical alternative to pastry pies, gaining traction in North America in the early 20th century alongside kin like crumbles and cobblers. While Britain popularized the oatless “crumble,” the American-style crisp typically includes oats in the topping for extra crunch. Plums, with their natural pectin and sweet-tart profile, became a regional and seasonal favorite, especially late summer through early fall when the fruit is abundant.
