This super simple mixed berry cobbler is made with frozen berries and has a sweet biscuit like topping. Top with vanilla ice cream for a classic, southern summer dessert!
Add the frozen berries to a large nonstick pot over medium heat. Add in the sugar, lemon juice, salt, and fresh mint and stir to combine.
Once the fruit begins to break down, reduce the heat to medium-low and cook gently for 10-15 minutes stirring frequently.
Mix together the cornstarch and water to make a slurry and then slowly add to the berries until thickened. Remove from the heat and set aside.
Topping
Preheat the oven to 375°F.
In a large bowl, whisk together the flour, sugar, baking powder, and salt.
Cut the cold butter into the dry ingredients by flattening the cubes into disks. You want the butter to remain in relatively large chunks (about quarter sized).
Slowly drizzle the cream over top, combining with a fork as you go. Using a spatula or bowl scraper, fold the dough over onto itself a few times in the bowl until it comes together into a sticky dough.
Pour the mixed berry filling into a baking dish. Then dot the topping all over the berries until they're mostly covered.
Before baking, lightly brush the top of the biscuits with cream and sprinkle with sparkling sugar if desired.
Bake at 375°F for 30-40 minutes until the filling is bubbly and the top is golden brown.
