In a medium saucepan, combine 1 cup of granulated sugar, water, and light corn syrup. Heat until the mixture reaches 245°F using a candy thermometer.

In a mixing bowl, combine the fruit-flavored gelatin and the remaining 2 cups of granulated sugar. Mix until well combined.

Once the sugar mixture reaches the correct temperature, pour it over the gelatin mixture and stir until the gelatin has fully dissolved.

Pour the mixture into an 8×8 inch baking pan lined with parchment paper. Let it sit for 24 hours to set completely.

Once set, cut the gumdrops into desired shapes and sizes with a small sharp knife or pizza cutter.

Coat the gumdrops in granulated sugar just before serving to prevent sticking.
