Rustic, oat-free late summer dessert with juicy blackberry filling and a golden shortbread-style crumble topping. Simple pantry staples, big comfort flavors.
Preheat your oven to 375°F (190°C) with the rack positioned at the center. Gather and measure all ingredients onto a clean work surface before starting.
In a large bowl, whisk together 0.5 cups granulated sugar (for filling), 1 tablespoons cornstarch, 1 teaspoons lemon zest, ¼ teaspoons ground cinnamon, and 1 pinch kosher salt (for filling) until fully combined with no lumps of cornstarch remaining and the lemon zest has released its oils into the sugar
Add 4 cups fresh blackberries and 2 tablespoons fresh lemon juice to the sugar mixture. Gently fold with a silicone spatula until every berry is evenly coated. The sugar will immediately begin drawing out a glossy, fragrant juice.
Transfer the coated berries and every drop of accumulated juice into an ungreased 8×8 inch ceramic or porcelain baking dish. Spread into an even, flat layer.
In a medium bowl, stir together 1 cups all-purpose flour, 0.5 cups granulated sugar (for topping), and 0.5 teaspoons kosher salt (for topping). Pour in 6 tablespoons unsalted butter, melted and cooled and 1 teaspoons vanilla extract. Stir with a fork until the dry ingredients are fully absorbed and the mixture forms irregular, sand-like clumps.
Scatter the crumble evenly over the blackberry filling. Leave a few small gaps at the edges so the vibrant berry juices can bubble up decoratively during baking.
Bake on the center rack for 30min or until the topping is light golden brown and the fruit filling is vigorously bubbling along the sides of the dish.
Transfer to a wire cooling rack and let rest for 15 min at least. This allows the cornstarch to set the juices into a spoonable sauce. Serve warm with a generous scoop of vanilla ice cream.
Notes
Notes
Storage: Cool completely before covering. Store on the counter for up to 24 hours, or refrigerate in an airtight container for up to 4 to 5 days.Reheating: Avoid the microwave — it steams the topping soft. Reheat in a 350°F oven for 10 to 12 minutes to re-crisp the crumble beautifully.Make Ahead: Assemble the berry filling and the dry crumble separately on the morning of your event. Combine and bake just before serving.Frozen Berries: Do not thaw. Toss directly from frozen and extend baking time by 5 to 8 minutes.Sugar Adjustments: Very sweet berries? Reduce filling sugar to ⅓ cup. Very tart? Add 1 tablespoon pure maple syrup.Oat Variation: Replace ¼ cup of flour with ½ cup old-fashioned rolled oats for a nuttier, chewier topping.Vegan Option: Swap butter for melted plant-based butter sticks or refined coconut oil. Use bone-char-free sugar and serve with coconut milk vanilla ice cream.Gluten Free: Substitute the all-purpose flour 1:1 with a certified gluten-free baking blend.For Two: Halve all ingredients and divide between two 6 oz ramekins. Bake at the same temperature for 20 to 25 minutes.
