If you want to offer something different to the trick-or-treaters, you can offer homemade candy. How are you going to make some homemade candy? You can decide what type of homemade candy you would like to make. Do you want to offer peanut butter cups?
You can definitely make your own. You can also control the taste and the ingredients that you will use. If you want to offer homemade lollipops, you can also do this by using flavoring oil that will also allow the candy to harden. Expect that the taste will be stronger because you will not be using alcohol-based flavoring. You can also make caramel if you want to provide something that is chewy.
