2 cups dark chocolate, melted
1 cup peanut butter
2 tbsp butter, melted
1 tsp vanilla
1 cup powdered sugar
1. Melt chocolate in double boiler or microwave. Spread thin layer of chocolate on parchment paper and put in freezer for 3 minutes to set chocolate.
2. While the chocolate is in the freezer, combine the peanut butter, melted butter, vanilla, and powdered sugar to make the peanut butter 'dough'. Spread peanut butter over the frozen chocolate and place back in freezer for 2 minutes.
3. Pour remaining chocolate over top of the peanut butter and spread evenly. Place tray back in freezer for 20 minutes.
4. Cut bark into one to two inch chunks. Bark is best kept cold to prevent the peanut butter from oozing out of the chocolate.. but peanut butter and chocolate is good no matter the temperature.
