This one really doesn’t require a recipe, since the glory of a sundae is in the toppings and the eye of the beholder. For ours, we stayed pretty classic (vanilla, chocolate, and dulce de leche ice cream, chocolate sauce, sliced almonds, and luxardo maraschino cherries), but the possibilities are endless. Make it a banana split, add crushed up toffee or candy bars, or pour over a shot of espresso for a play on the classic Italian dessert affogato. With good ice cream and this chocolate sauce, you really can’t go wrong.
Combine chocolate and cream in a small saucepan over low heat. Let cook, stirring frequently, until the chocolate has melted and the sauce is smooth. Stir in vanilla extract.
