With a mixer, beat heavy whipping cream until thick.
Pour in sweetened condensed milk and vanilla extract and fold in until smooth.
Add in banana slices and Reese’s chips and stir. Alternatively, you can add these in when you pour the ice cream into a container.
Next, pour ice cream into a freezer safe container. Freeze for 5-6 hours or overnight. When it is time to serve, remove from freezer and let sit on the counter to soften for 5-10 minutes before serving.
