14 oz candy melt (like candy quik or almond bark)
1/3 c light corn syrup or sweetened condensed milk
Melt the candy melt, stir in the corn syrup. There you have it.
The texture is improved with letting it sit overnight before you sculpt with it, though.
Really, any amount of corn syrup/sc milk stirred into the chocolate will make it have a playdough texture.
We did 1 bag of chocolate chips plus 5 tablespoons corn syrup, and that worked.
Also did 7 oz candy melt plus 6 tbsp corn syrup, and that worked too.
Makes into perfect tootsie rolls!
