Two Toners

Two layers of melted chips, one marshmallow middle, zero baking. This is old-school church-cookbook candy: butterscotch and walnuts on the bottom, mini marshmallows in the middle, and chocolate poured over the top.

The double boiler isn’t optional. Butterscotch and chocolate chips both seize fast over direct heat, going chalky and grainy if they get too hot. Hot, not boiling water under the bowl keeps the temperature low enough for smooth melting. A tablespoon of oil per layer keeps things glossy and helps the chips set up creamy instead of brittle.

Patience between layers is key. Pour the butterscotch base, scatter the marshmallows on top while it’s still warm so they stick, then chill briefly before adding the chocolate so the layers don’t bleed into each other. Once cold, the chocolate sets hard. The “hammer and chisel” line in the directions isn’t entirely a joke. A heavy chef’s knife and a confident hand do the work.

Kitchen Tips

• Toast the walnuts for a few minutes in a dry skillet before stirring in. Toasted nuts add deeper flavor and better crunch.
• Chill in the fridge, not the freezer. Freezing makes the chocolate prone to bloom (white streaks) and harder to slice cleanly.
• Run the knife under hot water and wipe dry between cuts to keep edges sharp.
• Store between sheets of parchment. Pieces stick to each other if stacked directly.

Variations

• Swap walnuts for chopped pecans or salted peanuts for a different crunch.
• Use peanut butter chips in place of butterscotch for a chocolate-PB pairing.
• Sprinkle flaky sea salt over the chocolate before it sets for a salted-candy edge.
