Pour cream into a large bowl and whip with a hand mixer (or in the bowl of a stand mixer fitted with the whisk attachment) on medium-high speed. Once it starts to thicken, slowly add sugar until fully incorporated.

Add vanilla and bourbon and whip until stiff peaks form, being careful not to over-mix (or you'll end up with bourbon butter, which actually sounds pretty good... I'll file that away for future use).

Serve immediately.
