Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

For the fruit filling:

• 4 cups diced fresh rhubarb
• 2 cups raspberries
• 1 cup granulated sugar
• 2 tablespoons water

For the crumble topping:

• 1 cup all-purpose flour
• ½ cup granulated sugar
• ½ teaspoon cinnamon
• ½ teaspoon kosher salt
• ½ cup unsalted butter, cold and cubed

Optional serving ideas:

• Vanilla ice cream
• Homemade whipped cream
• Greek yogurt with honey drizzle

Directions

1. Preheat your oven to 350°F and place the oven rack in the center position.
2. Lightly grease a shallow 1½-quart casserole dish or a 10-inch pie dish.
3. In a large mixing bowl, combine the diced rhubarb, raspberries, sugar, and water. Stir gently until the fruit is evenly coated.
4. Transfer the fruit mixture into the prepared baking dish and spread it evenly.
5. In another bowl, whisk together the flour, remaining sugar, cinnamon, and kosher salt.
6. Add the cold cubed butter to the dry ingredients. Using a pastry cutter, fork, or your fingertips, mix until the topping becomes crumbly and clumps together slightly.
7. Sprinkle the crumble mixture evenly over the fruit filling.
8. Bake for about 50 minutes, or until the topping is golden brown and the fruit filling is bubbling around the edges.
9. Allow the crisp to cool for at least 20 minutes before serving so the filling can thicken slightly.
10. Serve warm with ice cream or whipped cream if desired.

Variations

For extra texture, stir a few tablespoons of quick oats or chopped nuts into the crumble topping before baking. Pecans or walnuts work especially well.

If you enjoy warm spices, try adding nutmeg, cardamom, or apple pie spice to the topping for a slightly different flavor profile.

For a richer caramel-like sweetness, substitute half of the granulated sugar with brown sugar.

To make the dessert gluten-free, replace the all-purpose flour with your favorite gluten-free baking flour blend.
