Make the Cobbler Filling: Preheat oven to 350 degrees Fahrenheit. Dice peaches into ½-inch chunks. Melt butter in saucepan over medium-high heat, then stir in diced peaches, brown sugar, bourbon, vanilla, lemon juice, cinnamon, nutmeg, ginger, and salt until a uniform sauce forms.
2 fresh peaches, 2 tablespoons unsalted butter, ¼ cup brown sugar, 1 tablespoon bourbon whiskey, 1 teaspoon vanilla bean paste, ½ lemon, 1 teaspoon ground cinnamon, ½ teaspoon ground nutmeg, ½ teaspoon ground ginger, ¼ teaspoon fine sea salt
Cook until peaches are softened and filling is bubbly and slightly thickened (about eight minutes). Remove from heat.
Prepare the Crust: Unroll crust flat onto baking sheet and place in oven to bake per package directions. Let cool for a few minutes then break up into pieces.
1 pre-made pie crust
Build the Ice Cream Base: While the filling and crust cool, use stand mixer with whisk attachment fitted or hand mixer to beat heavy cream until fluffy, stiff peaks form.
2 cups heavy cream
Fold the sweetened condensed milk into the whipped cream, followed by the cooled peach cobbler filling, until combined.
14 ounces sweetened condensed milk
Assemble and Freeze: Add the ice cream base and pie crust pieces to freezer-safe container in alternating layers, starting and ending with layers of crust. Transfer container to freezer for at least six hours. Four hours produces soft-serve consistency, after six hours you can get pretty firm scoops, and eight hours/overnight is fully frozen.
