Ingredients
Scale
- 6 cups (180g) Rice Krispies cereal
- 10 oz (283g) marshmallows (about 40 large or 4 cups mini)
- 3 tablespoons (42g) unsalted butter
- 1 teaspoon vanilla extract (optional)
- Pinch of salt
- Optional add-ins: mini chocolate chips, peanut butter chips, chopped nuts (almonds or pecans), dried fruit (cranberries or raisins)
Instructions
- Line a 9×13-inch (23×33 cm) baking pan with parchment paper or lightly grease it. Set aside. (5 minutes)
- In a medium saucepan over low heat, melt 3 tablespoons (42g) of unsalted butter until fully liquid but not browned. (2-3 minutes)
- Add 10 oz (283g) marshmallows to the melted butter. Stir gently and constantly until marshmallows are melted and smooth, glossy and thick. Keep stirring off heat if small lumps remain. (4-5 minutes)
- Remove from heat and stir in 1 teaspoon vanilla extract and a pinch of salt. (30 seconds)
- Pour 6 cups (180g) Rice Krispies cereal into the marshmallow mixture. Fold gently with a wooden spoon or spatula to coat evenly without smashing the flakes. (1-2 minutes)
- Transfer mixture into the prepared pan. Press down firmly and evenly with a buttered spatula or wax paper, but do not compact too much. (2 minutes)
- Let bars cool at room temperature for at least 30 minutes to firm up. You can refrigerate to speed up but avoid freezing. (30+ minutes)
- Lift bars out using parchment paper edges and cut into squares or rectangles. Store leftovers in an airtight container. (5 minutes)
Notes
Melt butter and marshmallows over low heat to avoid burning. Use fresh marshmallows for best texture. Fold cereal gently to keep flakes intact. Press mixture evenly but not too hard to avoid dense bars. Store bars in airtight container at room temperature for up to 3 days or freeze for up to 1 month. Warm bars briefly in microwave if too firm.
