Puree the peaches in a food processor or something similar.

Put the peaches in a saucepan and heat them up. Whisk in the gelatin. Once it gets to a boil, let it bubble (while stirring) for 2 minutes.

Pour the peach mixture into the 8x8 pan. It does not need to be greased. Stick them in the fridge for at least 30 minutes.

After the gummies have set, slice them and take them out of the pan. If you want, you can add sugar just before eating, otherwise just eat them as peach gummies, they don't really need any sugar! Note: don't store the ones coated in sugar as the sugar will get watery. Store them without being sugar coated.
