I can see the demand for chocolate kringle is high enough that I need to take some action here! Also I don’t have a bake-in chocolate filling on the site anywhere. The time is now! This is basically a chocolate rugelach filling, but use it however you see fit!
6-7 ounces (about a cup) cup finely chopped dark chocolate
4.5 ounces (2/3 cup) granulated sugar
1 teaspoon cinnamon
3 tablespoons melted butter, cooled
Stir together the butter, sugar and cinnamon, then stir in the chocolate. Alternately you can chop everything up together in a food processor. Me, I’d rather not get the machine dirty if I don’t have to!
