Cooling and cutting the bars
Place the dish in the refrigerator and let the mixture cool for at least an hour. During this time, the chocolate will harden and bind the cereals.
Once the bars are set, remove them from the mould using parchment paper. Place the mixture on a cutting board and slice it into bars or squares, depending on your preference. A sharp knife is ideal, especially if it is slightly heated under hot water and wiped dry before cutting.
Storage tips
For longer storage, the bars freeze very well. Wrap them individually in parchment paper and place them in a bag or container suitable for freezing. They will keep for several months and can be enjoyed directly from the freezer or after a short passage at room temperature.
