Bark is a spectacularly easy way to create your own ideal candy bar. With the combination of melted chocolate and toppings—like candies, chopped pretzels, even cereal (Lucky Charms Bark, anyone?!), you can create unique and creative chocolate candy that’s fun to make, fun to eat, and fun to share.

Key Ingredients You Need & Why

White Chocolate: You need a pound of white chocolate to make this triple-layered bark. Or feel free to use semi-sweet or dark chocolate, or use white chocolate for 1 layer and semi-sweet/dark chocolate for the other chocolate layer.
Vegetable Oil: Just a touch of oil helps the white chocolate melt into an extra-smooth, easily spreadable consistency.
Peanut Butter: You want to use the smooth and creamy processed kind for this recipe. Natural peanut butter is great most of the time, but won’t do the filling any favors—it won’t set.
Confectioners’ Sugar: To thicken & sweeten the peanut butter filling.

You also need butter, vanilla extract, and salt. Plus Reese’s Pieces, the favorite candy of E.T. the Extra Terrestrial, as well as peanut butter lovers everywhere.

The Best White Chocolate to Use for Bark Candy

Because it’s the main component here, it’s important to use quality white chocolate. White chocolate morsels are fabulous in white chocolate peanut butter cookies because they hold their shape, but are not ideal for melting into bark. They contain stabilizers, preventing them from melting into a silky-smooth consistency.

And while candy melts are great for coating cake pops, in a recipe like this, you’ll really taste the difference between actual chocolate and candy melts.

I recommend Ghirardelli, Baker’s, or Lindt brand bars of white chocolate. You can find them in the baking aisle of most grocery stores and they’re usually sold in 4-ounce bars.

FLAVOR TIP: Try mixing it up and doing a layer of semi-sweet or dark (bittersweet) chocolate on the bottom, and keep just the top layer as white chocolate. YUM. You’ll love the white-and-dark layered look, like in my favorite peppermint bark recipe.

These Step-by-Step Photos Will Help

Let’s make some peanut butter white chocolate bark! Melt half the white chocolate with 1/2 teaspoon of oil in the microwave in 20-second increments, stirring in between each increment (so the white chocolate melts evenly and doesn’t burn). The little bit of oil makes the white chocolate satiny smooth and easy to spread. I like to use a microwave-safe glass liquid measuring cup for melting chocolate, because the pour spout is super helpful for the next step.

When completely melted, pour and spread it into a lined 9×13-inch pan.

Place the pan in the refrigerator for just 10–15 minutes to set the bottom layer. You don’t want it to set for too long and completely harden, or else the layers will separate.

While the bottom layer of white chocolate is setting, make the peanut butter layer. It tastes exactly like the creamy yet crumbly center of a Reese’s Peanut Butter Cup. An electric mixer makes quick work of this step.

For the top layer, repeat the melting and spreading process you did for the bottom white chocolate layer.

Now for the topping: a generous handful of crushed/chopped Reese’s Pieces. The little candies on top provide a nice crunch to the otherwise soft and creamy bark.

Refrigerate the finished bark in the pan for 30 to 60 minutes, and then lift the entire thing out of the pan by holding on to the edges of the parchment paper. Use a sharp knife to cut the bark into pieces. There may be some cracking—that’s normal.

This peanut butter white chocolate bark should be stored in the refrigerator, because it softens up very quickly at room temperature. You’ll love it cold from the fridge!
