Last month, I bought this chocolate covered Oreo cookie mold from Fancy flours. You use colored candy melts to add the details, (dots, stripes, hearts and flowers) and let them set in the fridge.
Next, for each color cookie, you fill the mold about 1/3 full of melted chocolate, press in a Double Stuff Oreo (I used golden vanilla) and fill the mold with more melted chocolae. Chill for another 10 minutes.
Aren't they cute?
