Tips
Spray your pressing tool generously with nonstick spray to prevent sticking and make spreading easier.
Work quickly after adding cereal to the marshmallow mixture, as it begins to set as it cools.
For easier cutting, use a sharp knife dipped in hot water and wiped clean between cuts.
Good to Know
Store in an airtight container at room temperature for up to 5 days.
Prepare bars up to 2 days in advance and store covered.
Cut into squares and serve at room temperature. Optional sea salt topping adds brightness.
Common Mistakes
Overheat marshmallows to avoid burning and creating a gummy texture.
Don't skip the nonstick spray on pressing tools to avoid sticking and tearing.
Mix quickly after adding cereal so the marshmallow sets evenly throughout.
