What You’ll Need For Mixed Berry Cobbler
- Berries: Use your favorite kind, a combination of blueberries, blackberries, strawberries work great (frozen berries require thawing and draining)
- Sugar: Granulated sugar lets berry flavor shine
- Flour: Combination of flour and cornstarch for best texture
- Cornstarch: Helps thicken filling
- Salt: Balances flavors
- Flour: Use all-purpose flour, avoid whole-wheat to prevent earthy flavor

How to Make Cobbler
- Prep:
- Preheat oven to 375°F. Butter a 10-inch cast-iron skillet or baking dish.
- Filling:
- Combine berries, half the sugar, flour, cornstarch, and salt in skillet. Mix well and spread evenly.
- Topping:
- Mix crumble ingredients in bowl until sandy with coarse lumps.
- Assemble:
- Spread topping evenly over filling and gently press down.
- Bake:
- Bake until filling bubbles and topping is golden, about 35–40 minutes. Let rest before serving.

Tips for Success
- Avoid kneading the crumble topping to keep it sandy and coarse
- Let cobbler rest 10 minutes after baking to thicken filling
- Use a 9x9-inch baking dish if a cast-iron skillet is unavailable
- Frozen berries work if thawed and drained
