First melt the chocolate either in the microwave or stove top. Mix in 1/2 tsp of peppermint extract into melted chocolate. Put parchment paper in a 8x8 or 9x9 square dish. Pour the melted chocolate and evenly spread into a thin layer using a rubber spatula.
Place in freezer for 20 minutes. While chocolate is freezing, mix vanilla vegan yogurt and 1/2 tsp of peppermint extract in a bowl.
Take dish out of freezer. Pour peppermint vanilla yogurt over frozen chocolate and spread evenly.
Using a dropper, place single droplets of natural red food dye on top of vanilla peppermint yogurt. Then use a toothpick to make swirled marble designs on top. (Careful not to over mix)
Place in freezer for at least 2 hours or over night. Once yogurt top is completely frozen, use a knife and cut into raw pieces. Enjoy!
