- 3 tablespoons (42g) unsalted butter
- 2 tablespoons (30ml) heavy cream (or milk)

- 1 1/2 cups (255g) semi-sweet chocolate chips (or chopped chocolate)
- 1 tablespoon coconut oil or butter (for shine and easier slicing)
- Optional: flaky sea salt for finishing
Preparation Time
- Prep time: 20 minutes
- Chill time: 1–2 hours
- Total time: About 2 hours 20 minutes
Step-by-Step Instructions
Step 1: Prep the Pan
Line an 8×8-inch pan with parchment paper (leave overhang for lifting). Lightly grease.
Step 2: Make the Rice Krispy Base
In a large pot over low heat, melt butter. Add marshmallows and stir until completely melted and smooth.
Remove from heat and stir in vanilla and salt (if using). Fold in Rice Krispies until evenly coated.
Press mixture firmly into the prepared pan (use a greased spatula or parchment to press it flat). Let set 10 minutes.
Step 3: Make the Caramel Layer
Option A (caramels): In a saucepan over low heat, melt caramels with butter and cream, stirring constantly until smooth. Stir in a pinch of salt.
Option B (condensed milk caramel): In a saucepan over medium-low heat, combine condensed milk and butter. Cook, stirring constantly, until thick and golden (about 8–12 minutes). Stir in a pinch of salt.
Pour caramel over the base and spread evenly. Chill 30–45 minutes until firm.
Step 4: Add the Chocolate Topping
Melt chocolate with coconut oil (microwave in 20-second bursts or use a double boiler). Stir until smooth.
Pour over caramel and spread evenly. Sprinkle flaky sea salt on top if desired.
Step 5: Chill and Slice
Refrigerate 1–2 hours until fully set. Lift out using parchment and slice into bars with a sharp knife.
Tip: For clean cuts, warm the knife under hot water, wipe dry, then slice.
Serving Suggestions
- Serve chilled for sharp layers, or let sit 10 minutes for softer caramel.
- Cut into mini squares for dessert trays and parties.
- Pair with coffee or hot chocolate for a cozy treat.
- Add a scoop of vanilla ice cream for a plated dessert.
- Wrap individually for bake sales or lunchbox treats.
