To make the hot fudge, place the heavy cream, butter, corn syrup, and sugar in a medium saucepan. Bring to a boil over medium heat.

Boil for 3 minutes, stirring occasionally.

Remove from heat and add in the chocolate and vanilla. Stir until the chocolate has melted and the hot fudge comes together. Allow to cool for 15 minutes.

To make the sundaes, place big scoops of vanilla ice cream into 2 bowls.

Place the heavy cream and sugar in a bowl. Mix on high with a hand mixer until stiff peaks form.

Drizzle hot fudge over top of the vanilla ice cream, place a dollop of whipped cream on top, and top it off with a cherry. Sprinkle with sprinkles and enjoy.
