For the ice cream: Whip the cream with an electric mixer until stiff peaks form.
Pour the condensed milk into a separate bowl and gently fold in the whipped cream until smooth and lump-free. Pour into a pan and sprinkle with the cinnamon cereal. Press a sheet of wax paper to the surface (to avoid crystals) and freeze until solid, up to 6 hours.
For the crumble: Combine the flour, brown sugar, butter and cinnamon cereal in a large
bowl. Stir well to evenly distribute butter.
For the cobbler: Preheat the oven to 375 degrees F. Place the berries in a large bowl and sprinkle with the granulated sugar, prosecco and lemon juice. Let sit until juice forms.
Mix together the flour, baking powder and salt in a mixing bowl. Add the melted butter, vanilla and cinnamon cereal. Transfer to a small baking dish or cast-iron skillet. Top with berries and then crumble.
Bake until golden brown and bubbly, 35 to 40 minutes. Serve with the ice cream on the side.
