In a small bowl, mix butter and corn syrup until well combined.

Add 2 cups of powdered sugar, food coloring, and extract, then beat until smooth. Adjust flavoring as desired.

Stir in another cup of powdered sugar.

Transfer mixture onto a cutting board dusted with the remaining cup of powdered sugar.

Knead the dough until smooth and fully incorporated.

Shape into 1-inch balls, then roll each in granulated sugar.

Flatten slightly with a fork to create pumpkin ridges.

Insert a half-pretzel into the top as a stem, using another pretzel for support.

Shape small pieces of green candy into leaves and attach them to the pretzel stems.

Let the patties dry uncovered for 24 hours.

Store in an airtight container until ready to serve.
