Equipment

  • Small saucepan - for gently melting marshmallows and cream.
  • Whisk or silicone spatula - to keep mixture smooth and prevent sticking.
  • Blow torch or kitchen torch (optional) - for quick toasting on top.

Ingredients

  • 150 g 1 1/2 cups mini marshmallows
  • 120 ml 1/2 cup heavy cream
  • 30 g 2 tbsp unsalted butter
  • 5 g 1 tsp vanilla extract
  • 2 g 1/2 tsp ground cinnamon
  • Pinch fine sea salt

Instructions

  • Combine cream and butter: In a small saucepan over low heat, warm 120 ml (1/2 cup) heavy cream and 30 g (2 tbsp) unsalted butter until the butter melts and the mixture steams. You should smell a gentle dairy sweetness.
  • Add marshmallows: Stir in 150 g (1 1/2 cups) mini marshmallows. Keep the heat low so the marshmallows soften slowly. The mixture will go glossy and begin to thicken in about 2 to 3 minutes.
  • Whisk to smooth: Use a whisk or silicone spatula to keep everything moving, scraping the pan bottom. The texture will change from stringy to silky as the marshmallows fully melt.
  • Flavor it: Remove from heat and stir in 5 g (1 tsp) vanilla extract, 2 g (1/2 tsp) ground cinnamon, and a pinch of sea salt. The aroma will shift to warm vanilla and spice.
  • Adjust consistency: If the dip seems too thick, whisk in an extra 15-30 ml (1-2 tbsp) warm cream to loosen it. For a thicker dip, let it sit 3 to 5 minutes; it will set slightly as it cools.
  • Toast the top (optional): For a toasted marshmallow finish, transfer to a shallow bowl and brown the surface with a kitchen torch until light amber. You’ll get a crisp, caramelized layer that adds texture against the silky dip.
  • Serve warm: Set the dip next to 4 servings of hot sweet potato fries. The contrast between the fry’s caramelized edges and the dip’s creamy sweetness is when the magic happens.

Notes

  • Consistency tweak: Warm cream thins the dip; cool it briefly to thicken for dipping.
  • Flavor swap: Use maple extract or a little maple syrup for a deeper pairing with sweet potatoes.
  • Toasting tip: If you don’t have a torch, run under a preheated broiler for 30-45 seconds while watching closely.
