Dark chocolate pistachio bark is an easy homemade candy that comes together in about 20 minutes. Melted dark chocolate is filled with sweet toffee and crunchy pistachios that's spread into a thin candy bark.
Choose a baking sheet that will fit into your refrigerator and line it with parchment paper. Set aside.
In a microwave-safe bowl, add chocolate melting wafers and microwave in 30 second increments, stirring until melted. Alternatively, melt using a double boiler on the stove top.
Add pistachios and toffee to melted chocolate. Stir gently until incorporated.
Pour chocolate mixture onto your parchment lined baking sheet. Using a spatula, spread to about ¼ inch thickness to create a 10 to 12 inch oval.
Transfer baking sheet to the refrigerator or freezer to harden for about 10-15 minutes. Break into pieces and store in a sealed container at room temperature for up to 2 weeks.
Notes
Candy bark will keep at room temperature for about 2 weeks in a tightly sealed container.
I do not recommend substituting melting wafers with chocolate chips. Candy bark is tempered chocolate that's meant for melting and at-home candy making. Chocolate chips are meant to hold their shape and solidify with a dull, soft texture instead of the candy "snap" you achieve with melting wafers.
Pistachios can be substituted with any nuts you have on hand, like pecans, walnuts, or almonds.
Toffee bits can be substituted with a chopped toffee candy bar.
