I can’t think of a better way to enjoy plump, juicy, and delicious wild summer blackberries than baked in a hot and bubbly cobbler. Easy to make with simple ingredients, cobblers are a Southern favorite and perfect with a big scoop of vanilla ice cream. No baking skills are required for this dessert, so anyone can make it.
Prepare the blackberry filling: Heat the blackberries with the sugar in a large saucepot set over medium-high heat. Stir often. As the blackberries and sugar cook, combine the cornstarch and water. Stir into the blackberries and continue to cook until bubbly and thickened. Remove from heat and stir in the lemon zest.
Transfer the blackberry filling to the prepared baking dish. Set aside.
Prepare the cobbler topping: Combine the flour, sugar, baking powder, and salt. Use a cheese grater or microblade grater to cut the cold butter into the flour. Add the heavy cream and mix until just combined.
Drop the cobbler topping over the top of the blackberry mixture.
Bake: Transfer to the oven and bake until the filling is bubbly and the topping is golden brown.
