Melt the chocolate with some oil of choice in the microwave. Do this in 10 second increments and stir until completely melted. Add to a small plate then cover the rim of your glass with a thick layer of chocolate. You can set the glass in the freezer for a few minutes to harden.
In a cocktail mixer, add your strawberry and dark chocolate liqueur, vodka, simple syrup, strawberry extract, half and half, handful of ice and food coloring (optional).
Shake well until everything is combined. Then, pour your drink into your prepared glass. You can add a sliced strawberry on the top of the drink for garnish or add it to the rim of your glass. Feel free to add some dark chocolate shavings on top of the drink for the finished look. Enjoy!
