Melt chocolate chips over low heat, or in microwave. Blend in extract. Dip crackers in melted mixture to coat, place on wax paper covered cookie sheets. Top with sprinkles or crushed candy, if desired. Refrigerate until firm, probably 1 or 2 hours. Another thought I had, spread each cracker with peanut butter before dipping in chocolate. These are easy, not to messy to make.
