Step-by-Step Instructions

Toasted Marshmallow Ice Cream

This custard-based ice cream is infused with fire-toasted marshmallows, giving the base a signature s 9mores smokiness and depth.

  1. Toast the Marshmallows
    • Arrange marshmallows in a single layer on a parchment-lined baking sheet.
    • Use a kitchen torch to evenly brown all sides, or broil briefly in the oven until deeply golden and fragrant (watch closely).
  2. Make the Custard Base
    • In a saucepan, heat cream and milk over medium heat until steaming.
    • Meanwhile, whisk together egg yolks and sugar until pale.
    • Slowly pour hot dairy into yolks, whisking constantly, then return mixture to saucepan.
    • Cook, stirring, until thick enough to coat the back of a spoon (170175AC / 7780C).

  3. Blend and Chill
    • Add toasted marshmallows to the hot custard. Blend until completely smooth and silky.
    • Pour mixture through a fine-mesh strainer into a clean bowl, stir in vanilla, and chill thoroughly (at least 4 hours).
  4. Churn
    • Process chilled custard in an ice cream maker according to manufacturer’s directions.
    • Freeze until set and scoopable, at least 4 hours.

Time-saving tip: Substitute your favorite vanilla or marshmallow-flavored ice cream in a pinch.

Homemade Hot Fudge Sauce

This decadent sauce is the backbone of a proper s 9mores sundae. Its warmth and richness elevate the entire experience.

  1. In a heatproof bowl, combine chopped bittersweet chocolate and butter.
  2. In a small saucepan, whisk together cocoa powder, sugar, corn syrup, and cream over medium heat until smooth and just bubbling.
  3. Pour hot mixture over chocolate and butter, let stand 1 minute, then whisk until glossy and combined.
  4. Stir in vanilla and a pinch of salt.
  5. Let sauce thicken slightly before using. Keep warm for assembly.

Short on time? Store-bought hot fudge works, but homemade delivers unmatched flavor and texture.

Graham Cracker Crumble

Crunch is a must, and this simple crumble balances out the gooey and creamy elements beautifully.

  1. Preheat oven to 325AC (165C). Crush graham crackers into small chunks and crumbs.
  2. Toss with melted unsalted butter, brown sugar, cinnamon (if using), and a pinch of salt.
  3. Spread on a parchment-lined baking sheet. Bake until golden and crisp, about 1012 minutes, stirring halfway through.
  4. Cool completely before using.

Torched Marshmallow Topping

The marshmallow capstone is essential for the authentic s 9mores experience.

  1. For the classic look, pile large marshmallows (or generous scoops of marshmallow fluff) on top of assembled sundaes.
  2. Use a kitchen torch to brown the marshmallows until deeply caramelized.
  3. If you don7t have a torch, marshmallows can be toasted under a broiler for just a few seconds—watch constantly!

Frequently Asked Questions (FAQs)

What if I don7t have an ice cream maker?

You can substitute store-bought vanilla or marshmallow ice cream for a quick fix. Alternatively, make a no-churn version by blending toasted marshmallows into sweetened condensed milk and folding into whipped cream before freezing.

Can I make this nut-free or gluten-free?

Yes. Use gluten-free graham crackers to make the crumble, and ensure all other ingredients are nut-free and free of cross-contamination.

What7s the best way to toast marshmallows safely indoors?

A kitchen torch offers precision and a campfire-like finish. Otherwise, broil marshmallows on a foil-lined tray, watching closely to prevent burning.

How far in advance can I prepare these sundaes?

Ice cream and hot fudge can be made up to two days ahead. Sundaes are best assembled just before serving to maintain distinct textures.

Are there other flavor combinations that work?

Absolutely! Try swapping homemade fudge for peanut butter sauce, or use dark chocolate ice cream and add caramel drizzle for a twist.
