Method
Prep the pan
- Line a 9x13 pan with parchment paper and spray lightly with cooking spray so the treats release cleanly.
Melt the marshmallow base
- Melt butter in a large pot over medium-low heat until it turns glossy.
- Add mini marshmallows and stir constantly until fully melted and smooth, with a thick, lump-free texture.
Flavor and combine
- Remove from heat and stir in caramel sauce, vanilla extract, and salt until evenly combined and glossy.
- Fold in Rice Krispies cereal quickly until evenly coated so no dry cereal pockets remain.
- Fold in the extra 1 cup mini marshmallows for gooey pockets.
Press and finish
- Press the mixture into the prepared pan using buttered hands, pressing firmly but not too hard to keep the bars chewy.
- Drizzle generously with additional caramel sauce and immediately sprinkle flaky sea salt on top.
- Let set for 30 minutes before cutting into 16 bars so the center pulls apart in stretchy layers.
Notes
Pro tip: work fast after adding the cereal so it stays thick and chewy—if it cools too much, re-warm the pot gently over low heat until fluid again. Store airtight in the fridge up to 5 days; freeze up to 2 months (thaw overnight in the fridge). For a dairy-light option, use plant-based butter and dairy-free marshmallows if you want a similar texture and sweetness.
