Ingredients for Blackberry Crisp

- 2 pints (24 ounces) blackberries (fresh or frozen, thawed)
- 1 tablespoon cane sugar (or granulated sugar)
- 1 tablespoon cornstarch (or arrowroot powder as a substitute)
- 1 teaspoon fresh lemon juice
- 1 teaspoon lemon zest
- 1 teaspoon vanilla extract
- Vanilla ice cream (for serving, optional)
- Topping:
- ¾ cup whole rolled oats (use gluten-free if needed)
- ¾ cup almond flour (or regular flour as a substitute)
- ½ cup brown sugar (packed)
- ½ cup crushed walnuts (or pecans for a different flavor)
- ¾ teaspoon cinnamon
- Heaping ¼ teaspoon sea salt
- 6 tablespoons firm coconut oil (or cold butter if preferred)
Step-by-Step Instructions
- Preheat the oven to 400°F (200°C). Grease an 8×8-inch or similar baking dish lightly with oil or butter.
- Prepare the filling: In a large bowl, combine the blackberries, cane sugar, cornstarch, lemon juice, lemon zest, and vanilla extract. Toss gently until the blackberries are evenly coated.
- Make the topping: In a medium bowl, mix the oats, almond flour, brown sugar, walnuts, cinnamon, and sea salt. Add the firm coconut oil and use your hands to work it into the mixture until it becomes crumbly.
- Assemble the crisp: Scoop the blackberry filling into the prepared baking dish, spreading it evenly. Sprinkle the topping over the blackberries in an even layer.
- Bake: Place the dish in the preheated oven and bake for 25 to 35 minutes, or until the fruit is bubbling and the topping is golden brown.
- Cool and serve: Remove from the oven and let cool for 5 minutes. Serve warm with a scoop of vanilla ice cream, if desired.
Perfect Pairings: Serving Suggestions
This Blackberry Crisp shines when served warm with a scoop of vanilla ice cream for a classic combo. For a dairy-free option, try coconut or almond milk ice cream. A dollop of whipped cream or a drizzle of honey can also add a delightful touch. Pair it with a cup of hot tea or coffee for a cozy dessert experience.
Keep It Fresh: Storage and Reheating Tips
Store leftovers in an airtight container in the fridge for up to 3 days. To reheat, pop it in the oven at 350°F for 10-15 minutes until warm, or microwave individual portions for 30-60 seconds. The topping may soften slightly, but the flavors will still be delicious!
Mix It Up: Recipe Variations
Swap blackberries for raspberries, blueberries, or a mixed berry blend for a twist. If you’re nut-free, omit the walnuts and add extra oats or sunflower seeds. For a gluten-free version, ensure your oats are certified gluten-free. You can also experiment with spices like nutmeg or cardamom for a unique flavor profile.
Quick Tips: Time-Saving Hacks
Prep the topping ahead of time and store it in the fridge for up to 2 days—just sprinkle it on when ready to bake. Use frozen blackberries (thawed and drained) if fresh ones aren’t available. A food processor can quickly combine the topping ingredients if you’re short on time.
Essential Tools: Equipment Guidance
An 8×8-inch baking dish is perfect for this recipe, but a pie dish or similar-sized oven-safe dish works too. A sturdy mixing bowl and a set of measuring spoons and cups will ensure accuracy. If you’re using coconut oil, a pastry cutter or your hands will help blend it into the topping mixture easily.
