Mash up strawberries to desired consistency. You can also use a food processor to process them to a smaller size. Add in the sweetened condensed milk and vanilla and mix to combine. Whip heaving whipping cream on medium speed until peaks begin forming. Combine with the strawberry mixture and mix all together. Pour into a cold bread pan and freeze for 5 hours. If adding any add-in ingredients, do so about halfway through the freezing time. Serve and enjoy! Makes about 16 ½ cup servings.
