Banana Split Sundaes for Two

Banana split sundaes for two skip the ice cream parlor entirely and build the whole sundae at home in 10 minutes. The microwave hot fudge sauce is the only thing that actually cooks: 2 ounces of semisweet chocolate melted in a glass measuring cup, then stirred together with corn syrup and sweetened condensed milk.

The corn syrup is the secret to a fudge sauce that stays glossy and doesn’t seize. It keeps the chocolate fluid even as it cools, so the sauce stays pourable on cold ice cream instead of hardening into a brittle shell. Skip it and the sauce turns chalky.

Sweetened condensed milk does the smoothing work, giving the sauce body and a caramelized milk-sugar note that makes it taste like real ice-cream-shop fudge instead of a thinned-down ganache. The 1:1 ratio of corn syrup to condensed milk is what makes this work; mess with it and the sauce won’t pour properly.

The quartered bananas arranged around the ice cream are the visual move that says “banana split” instead of “bowl of ice cream with sauce." Don’t slice them flat, quarter them lengthwise so they fan around the bowl.

Chef Tips

• Use the highest-quality chocolate you can. The whole sauce hangs on its flavor.
• Stop microwaving the chocolate just before it’s fully melted; residual heat finishes the job without scorching.
• Slice bananas just before serving. Browned bananas ruin the look.
• Use unsalted peanuts so they don’t fight with the sweet sauce.

Variations

• Sub salted peanuts and skip the unsalted to add savory contrast.
• Add 1 tablespoon dark rum to the sauce after melting for a grown-up version.
• Top with whipped cream and a maraschino cherry for the full soda fountain experience.
