Start by lining a sheet pan with parchment paper. This will prevent the bark from sticking and make for easy removal once it’s set.
In a double boiler or microwave-safe bowl, melt the finely chopped dark chocolate. If using the microwave, heat in 30-second intervals, stirring in between until smooth. If the chocolate seems too thick, you can add a tablespoon of vegetable shortening or coconut oil to achieve the desired consistency.
Once the chocolate is melted and smooth, pour it onto the lined sheet pan. Using a spatula, spread it evenly to create a thin layer. Aim for about 1/4 inch thickness for the perfect bark texture.
In the same manner as the chocolate, melt the peanut butter chips until smooth. If needed, you can add a bit more shortening or coconut oil to help with melting.
Drizzle the melted peanut butter over the dark chocolate layer. Use a knife or spatula to gently swirl the two together, creating beautiful marbled patterns.
Before the chocolate sets, sprinkle the mini peanut butter cups evenly over the top. Gently press them down into the mixture to ensure they stick.
Place the sheet pan in the refrigerator for about 1-2 hours or until the bark is completely set and firm. Once set, remove from the refrigerator.
Using your hands or a sharp knife, break the bark into irregular pieces. This adds to the rustic charm of the Chocolate Peanut Butter Cup Bark.
