Indulge in the delightful flavors of a plum crisp, a perfect dessert that combines the sweetness of plums with a crunchy, buttery topping. This recipe is simple to make and is sure to impress your family and friends. The combination of juicy fruit and a crisp oat topping creates a comforting and satisfying treat.
While most of the ingredients for this plum crisp recipe are common pantry staples, you may need to pick up fresh plums if they are not already in your kitchen. Additionally, cornstarch is essential for thickening the fruit filling, so make sure you have it on hand. The rest of the ingredients, such as rolled oats, flour, and brown sugar, are typically easy to find at any supermarket.

Ingredients For Plum Crisp Recipe
Plums: Fresh plums are the star of this dessert, providing a juicy and sweet base.
Granulated sugar: Adds sweetness to the fruit filling.
Cornstarch: Thickens the plum filling, ensuring it isn't too runny.
Rolled oats: Gives the topping a hearty and crunchy texture.
All-purpose flour: Helps bind the topping ingredients together.
Brown sugar: Adds a rich, caramel-like sweetness to the topping.
Ground cinnamon: Provides a warm, spicy flavor that complements the plums.
Unsalted butter: Melts into the topping, creating a deliciously crisp texture.
Technique Tip for This Recipe
When preparing the plums, ensure they are ripe but firm to achieve the best texture and flavor in your crisp. To pit the plums efficiently, slice them in half and twist the halves apart. Use a small spoon or the tip of a knife to remove the pit. For a more even distribution of sweetness and thickness, mix the granulated sugar and cornstarch thoroughly with the plums before transferring them to the baking dish. When making the topping, use your hands to mix the melted butter into the oats, flour, brown sugar, and cinnamon until the mixture resembles coarse crumbs. This ensures the butter is evenly distributed, resulting in a perfectly crumbly topping.

How to Store or Freeze Your Plum Crisp
Allow the plum crisp to cool completely at room temperature before storing. This helps prevent condensation, which can make the topping soggy.
For short-term storage, cover the baking dish tightly with plastic wrap or aluminum foil. Alternatively, transfer the plum crisp to an airtight container. Store in the refrigerator for up to 3-4 days.
To reheat, preheat your oven to 350°F (175°C). Place the plum crisp in an oven-safe dish and cover with aluminum foil. Heat for about 15-20 minutes or until warmed through. For a crispier topping, remove the foil during the last 5 minutes of reheating.
For freezing, first ensure the plum crisp is completely cooled. Transfer it to a freezer-safe container or wrap the entire baking dish tightly with plastic wrap followed by aluminum foil. Label with the date and freeze for up to 3 months.
When ready to enjoy, thaw the plum crisp in the refrigerator overnight. Reheat in a preheated oven at 350°F (175°C) for about 20-25 minutes or until the filling is bubbly and the topping is crisp.
For individual servings, you can freeze portions in airtight containers or freezer bags. Thaw and reheat as needed, following the same oven instructions for the best texture and flavor.
