Easy Stovetop Fruit Crisp Recipe

For the Streusel: Combine flour, nuts, brown sugar, salt, and cinnamon in a small bowl. Melt butter in 10-inch nonstick skillet over medium heat. Remove from heat and stir in flour mixture until moistened and mixture forms small clumps. Return to low heat and cook, stirring frequently, until streusel is golden brown and well toasted, 6 to 9 minutes. Transfer streusel to a large plate to cool (see note). Streusel can be made up to 5 days ahead. After cooling completely, store in an airtight container at room temperature.

For the Filling: Stir sugar, cornstarch, cinnamon, and salt in a small bowl. Add butter, plums, and sugar mixture to skillet and heat over medium heat, stirring, until butter is melted and sugar is dissolved, about 1 minute.

Increase heat to medium, cover, and cook, stirring occasionally, until plums are almost softened, about 8 to 10 minutes. Remove lid and cook until plums are cooked through and mixture has thickened slightly, about 5 minutes more.

Immediately top plums with streusel and serve.
