In a bowl, use a potato masher to mash the strawberries. Set aside.
Add the whipping cream, vanilla and sweetened condensed milk to the bowl of a stand mixer. Whip on high until you obtain stiff peaks. Add the mashed strawberries and mint, stirring carefully with a spatula until fully incorporated.
Pour the mixture into a cold-resistant metal loaf pan. Garnish with a few fresh strawberry slices and freeze for 4-5 hours. After 3-4 hours, the mixture will have taken on the texture of soft ice cream. For harder ice cream, leave in the freezer for at least 6 hours.
