In a large mixing bowl, pour in the heavy cream. Using an electric mixer, beat the cream on medium-high speed until stiff peaks form. This will take about 2-3 minutes.
In another bowl, combine the sweetened condensed milk and vanilla extract. Mix well until combined.
Gently fold the whipped cream into the condensed milk mixture using a spatula. Be careful not to deflate the whipped cream; fold until just combined.
Once fully mixed, transfer the ice cream mixture into an airtight container. Smooth the top with a spatula.
Cover the container and freeze for at least 4 hours, or until the ice cream is firm.
When ready to serve, let the ice cream sit at room temperature for a few minutes to soften slightly. Scoop and enjoy your creamy homemade ice cream!
