Whip the Cream: Get out your stand mixer with a whisk attachment (or use a hand mixer and a chilled metal bowl!). Beat the very cold heavy cream on high speed until it forms stiff peaks, which usually takes about 1 to 2 minutes. You want it firm and fluffy, like clouds!
Gently Fold in Sweetness: Carefully fold the entire can of sweetened condensed milk into your whipped cream. Be gentle to keep all that lovely air you just whipped in. If you're using vanilla extract, stir it in now too.
Add Your Favorites (Optional): If you're planning to mix in any extra goodies like chopped fruit, chocolate chips, or cookie crumbles, now's the perfect time to gently fold them into the creamy mixture.
Freeze for Fun: Transfer your delightful ice cream mixture into a freezer-safe container with a lid. Cover it up tightly (you can even press plastic wrap directly onto the surface to prevent ice crystals!). Place it in the freezer and let it chill for at least 6 hours, or ideally overnight, until it's perfectly firm and scoopable.
