Lightly toast the salted peanuts in a dry skillet for 2-3 minutes before adding to enhance their natural oils and deepen the peanut flavor throughout the bars.

Melt margarine over low heat and let it cool slightly before mixing with other ingredients to prevent the marshmallows from deflating prematurely.

Fold in the crispy rice cereal gently and quickly at the end to maintain maximum crunch—overmixing will crush the cereal and create a dense, mushy texture.

Use a sheet of parchment paper to press the mixture into the pan instead of your hands—this prevents sticking while creating even, uniform bars with consistent density.

Refrigerate the bars for at least 2 hours before cutting to set the structure properly, ensuring clean edges and preventing the bars from crumbling apart.
