Add the heavy whipping cream to the bowl of a stand mixer. Whip using the whisk attachment until thickened and stiff peaks just begin to form. NOTE: hand held mixer may also be used though will take slightly longer.
Slowly pour in the sweetened condensed milk while continuing to mix.
Turn the mixer to high and whip until thick and cream and large peaks form.
Add the flavoring ingredient (extract or drink mix) and fold in until well combined.
Pour the mixture into a large loaf pan and spread evenly.
Freeze for 6 to 8 hours. Before serving, allow the ice cream to sit at room temperature for five to 10 minutes to soften enough to scoop.
For Mix Ins
Allow ice cream to chill 1-2 hours until soft serve consistency.
Gently stir in mix in ingredients. NOTE: if adding thinned jam or a sauce, pour on top of ice cream and use a dinner knife to drag into the ice cream.
Allow to fully freeze before eating.
