Mash the strawberries with a fork or potato masher to your desired consistency—chunky or smooth, it’s your call. For a finer texture, pulse them a few times in a food processor.
In a large mixing bowl, stir together the mashed strawberries, sweetened condensed milk, and vanilla extract until fully combined.
In a separate bowl, beat the cold heavy cream with a hand mixer on medium speed until soft peaks form. You’re looking for light and fluffy—not stiff.
Gently fold the whipped cream into the strawberry mixture. Take your time here—use a spatula and light strokes to keep the mixture airy.
Pour the ice cream into a chilled loaf pan or other freezer-safe container. Smooth the top with a spatula.
Cover the pan and freeze for at least 5 hours, or until the ice cream is fully set. Note: If you’re adding extras (like mini chocolate chips or crushed cookies), sprinkle them in about halfway through the freezing time—around 2½ hours in.
