I always use Kosher salt in my kitchen! If using table salt, start with half the amount and adjust to taste, as it is much "saltier" by volume.
Instructions
Preheat the oven to 350°F and lightly grease a 9x13 baking dish.
In a medium saucepan, combine the cornstarch, 1 cup granulated sugar, and water over medium heat. Bring to a boil, stirring frequently. Once boiling, remove from heat and whisk in the butter until melted. Set aside.
In a medium bowl, whisk together the flour, sugar, baking powder, and salt. Stir in the milk and vanilla extract until fully combined.
Spread the berries out evenly in the baking dish. Pour the cornstarch mixture evenly over the berries.
Pour the batter over the top of the berries and smooth it out as best as you can. Bake for 50-55 minutes or until the top is golden brown and the berry filling is bubbling around the edges.
Let cool slightly before serving. Enjoy!
Notes
If you’re using a lot of blackberries, you can increase the sugar to 1 cup since they tend to be tart.
If using strawberries, cut the larger ones into smaller pieces so they bake evenly.
You can mix berries like blueberries, raspberries, blackberries, and strawberries for a great blend of flavors.
If you’re using frozen fruit, just keep in mind that it can create a more liquidy filling. For the best results, try to use fewer strawberries than other berries, since they have a higher moisture content.
