How to Make Black Raspberry Crisp

Prepare the Baking Dish

Preheat your oven to 350°F (175°C).

Grease a 14-inch cast-iron skillet or another oven-safe baking dish with 1 tablespoon of butter.

Spread the fresh black raspberries evenly across the bottom of the prepared pan.

Make the Berry Syrup

In a small saucepan, combine the boiling water, granulated sugar, dissolved cornstarch, and the remaining butter.

Cook over medium heat, stirring constantly, until the mixture thickens into a glossy syrup, about 5 minutes.

Pour the hot syrup evenly over the raspberries and gently stir to coat the fruit.

Prepare the Crumble Topping

In a medium mixing bowl, combine the flour, brown sugar, rolled oats, cinnamon, and melted butter.

Use a fork or pastry cutter to mix until the ingredients form coarse, crumbly clusters.

Sprinkle the crumble evenly over the berry filling.

Bake

Bake for 40 to 45 minutes, or until the topping is golden brown and the berry filling is bubbling around the edges.

If the topping begins browning too quickly, loosely cover the dish with foil during the final few minutes of baking.

Cool and Serve

Allow the crisp to cool for about 10 minutes before serving.

Serve warm with a scoop of vanilla ice cream or a dollop of whipped cream for the ultimate dessert experience.

Tips for Success

• Use ripe, fresh black raspberries for the richest flavor.
• If using frozen berries, thaw and drain excess liquid before baking.
• Do not overmix the crumble topping; a coarse texture creates the best crisp.
• Let the dessert cool slightly before serving so the filling thickens.
• Serve warm for the best combination of flavors and textures.
• Store leftovers covered in the refrigerator and reheat gently before serving.

Equipment Needed

• 14-inch cast-iron skillet or oven-safe baking dish
