Ingredients
Equipment
Method
Prep the pan
- Butter a 9x13 pan generously so the bars release cleanly after setting.
Make the spiced marshmallow binder
- Melt butter in a large pot over medium-low heat, then add molasses and stir to combine until glossy.
- Add all spices (cinnamon, ginger, cloves, nutmeg, and allspice) and stir for 1 minute until fragrant and evenly streaked through the mixture.
- Add marshmallows and stir constantly over medium-low heat until completely melted and smooth, with no lumps visible.
- Remove from heat and stir in vanilla extract until incorporated, then the mixture should look thick and uniform.
- Add Rice Krispies cereal and stir until evenly coated, with dry cereal disappearing into glossy marshmallow strands.
Press, drizzle, and set
- Press the mixture firmly into the prepared pan and smooth the top so it’s level and compact.
- Melt the white chocolate and drizzle over the top, then sprinkle with flaky salt while the drizzle is still glossy.
- Let set for 30 minutes before cutting, until the top looks matte and the bars hold their shape when pressed.
Notes
Pro tip: press the mixture firmly (and quickly) to prevent crumbling bars. Store covered at room temperature for up to 3 days or in the refrigerator for up to 5 days; freeze up to 1 month for best texture. For a lighter swap, use reduced-sugar marshmallows if available, keeping the same spice amounts for the gingerbread flavor.
