For the Fruit:
- 1 tablespoon of softened or melted butter to grease the pan
- 1/3 cup lightly packed light brown sugar
- 2 tablespoons corn starch
- 1/4 teaspoon ground ginger
- Pinch of salt
- 1 1/2 cups fresh blueberries
- 4–6 fresh ripe peaches, pitted and sliced
For the Cobbler Topping:
- 1/2 cup unsalted butter, melted until browned
- 3/4 cup lightly packed light brown sugar
- 1 teaspoon pure vanilla extract
- 1 1/2 cup all-purpose flour (or a gluten-free flour blend)
- 1 1/2 teaspoon baking powder
- 1/2 teaspoon kosher salt
- 1 large egg divided, yolk for the dough and egg white to brush on top of the dough
- Splash of milk
- 1/3 cup turbinado sugar (optional but nice)
- Whipped cream or vanilla ice cream for serving
- Place a rack in the upper third of the oven and preheat oven to 375 degrees F. Lightly grease a 9×13-inch baking dish with softened or melted butter and set aside.
- In a small bowl stir together brown sugar, cornstarch, ginger, and salt until evenly combined.
- Place the blueberries and sliced peaches in the prepared baking dish. Add the sugar mixture and toss gently until evenly coated. Set aside while you prepare the topping. The fruit will start to get juicy – that’s perfect!
- To prepare the topping, start by melted the butter just past when it pops and sizzles. The butter will become fragrant and the milk solids will toast and brown. Remove from the pan and place in a medium bowl to cool slightly.
- Add the sugar, vanilla, flour, baking powder, and salt to the bowl with butter. Add the beaten egg yolk and use a fork to work the ingredients into a shaggy dough. I found it easiest to also use my fingers to work the dough together to combine the ingredients evenly.
- Press the dough into rough coins, this can be messy and layer atop the prepared peaches and blueberries. Cover the dish though of course fruit bits will peek through.
- In a small bowl whisk together egg white and a splash of milk. Lightly brush the cobbler top and sprinkle generously with turbinado sugar. Bake for 25 – 30 minutes until the fruit is bubbling and the top is lightly golden. Rotate the dish in the oven halfway through baking to evenly brown.
- Remove from the oven and allow to rest for 15 minutes to cool just slightly before scooping and serving with vanilla ice cream. Cobbler is also delicious at room temperature or cold from the fridge. There’s no wrong way to enjoy it! Cobbler will last, covered in the refrigerator, for uo two 3 days.
