Place your strawberries into a large bowl and use a fork or a potato masher to mash the berries. Mash them until you have reached your desired consistency. You can mash them completely, or leave a few small pieces intact. Stir in the sweetened condensed milk and set aside.
Pour the chilled whipping cream into the bowl of your stand mixer and using the whisk attachment, mix until stiff peaks form. This will take about 5 minutes. Half way through the mixing, add the sugar. Be careful not to over mix.
Add the whipped cream to the strawberry mixture and fold everything together using a rubber spatula.
Gently fold in your chocolate chunks.
Pour into a loaf pan. We used a 5 X 11 inch loaf pan.
Cover with plastic wrap so that the plastic actually touches the surface of the mixture; this will eliminate ice crystals from forming on the top of your ice cream. As an extra precaution against ice crystals we also place the plastic covered loaf pan in an extra large freezer bag. Place your loaf pan in the freezer.
Freeze for about 6 hours, or overnight.
Scoop and enjoy!
