Introduction

This Reese’s Pieces Peanut Butter White Chocolate Bark is a delightful treat combining creamy peanut butter, smooth white chocolate, and crunchy candy pieces. It’s easy to make and perfect for sharing or indulging in a sweet snack.

The image shows several pieces of a two-layered dessert scattered on a white marbled surface. The bottom layer is light brown and looks like a thick cookie or caramel base with a slightly rough texture. The top layer is smooth and white, like a creamy frosting or white chocolate. On top of this white layer, there are broken pieces of small round candy in bright colors like red, orange, yellow, and dark brown spread unevenly, adding a crunchy texture. The pieces are cut into squares and triangles, some overlapping each other. Photo taken with an iphone --ar 4:5 --v 7

Ingredients

16 ounces (454g) white chocolate, coarsely chopped and divided*
1 teaspoon vegetable oil, divided
1 cup (250g) creamy peanut butter*
1/4 cup (4 Tbsp; 56g) unsalted butter, softened to room temperature
1 cup (120g) confectioners’ sugar
1/2 teaspoon pure vanilla extract
1/4 teaspoon salt
1/2 cup (100g) chopped Reese’s Pieces candies

Instructions

Step 1: Line a 9×13-inch baking pan with parchment paper, leaving enough overhang to lift the bark out later. Set aside.
Step 2: Place half (8 ounces/227g) of the white chocolate and 1/2 teaspoon of vegetable oil in a microwave-safe bowl. Melt in 20-second increments, stirring after each, until smooth. Pour into the prepared pan and spread evenly. Refrigerate uncovered for 10–15 minutes to set.
Step 3: In a medium bowl, beat peanut butter and softened butter with a hand or stand mixer until smooth, about 2 minutes. Add confectioners’ sugar, vanilla, and salt; beat until combined. Spread this mixture evenly over the chilled white chocolate layer. Return to refrigerator while melting the remaining chocolate.
Step 4: Melt the remaining white chocolate and 1/2 teaspoon oil using the same method. Pour and spread it evenly over the peanut butter layer. Sprinkle chopped Reese’s Pieces candies on top.
Step 5: Refrigerate the pan uncovered for at least 30 to 60 minutes to fully set. You may refrigerate it loosely covered for up to 1 day; expect some cracking on top when cutting due to the cold chocolate.
Step 6: Use the parchment overhang to lift the bark from the pan onto a cutting board. Cut into pieces with a sharp knife.
Step 7: Store the bark covered in the refrigerator for up to 1 week or freeze for up to 3 months.

Tips & Variations

Use a silicone spatula or offset spatula for smooth layering and even spreading of each layer.
Substitute creamy peanut butter with natural peanut butter for a fresher flavor, but ensure it is well mixed before use.
Add a pinch of cinnamon or a dash of cayenne pepper to the peanut butter layer for a subtle, spicy twist.
For a nut-free version, replace peanut butter with sunflower seed butter and omit Reese’s Pieces or use nut-free candy pieces.

Storage

Store the bark in an airtight container in the refrigerator for up to 1 week to keep it fresh and firm. You can also freeze the bark for up to 3 months; thaw in the refrigerator before serving. When reheating, avoid direct heat to prevent melting—simply bring to room temperature for a few minutes before enjoying.

How to Serve

The image shows many pieces of peanut butter bars arranged on a white marbled surface. Each bar has three layers: the bottom layer is a light brown peanut butter crust with a slightly crumbly texture, the middle layer is a smooth caramel peanut butter filling in a darker golden brown, and the top layer is a thick, creamy white frosting. The frosting is decorated with colorful candy pieces in red, orange, yellow, and dark brown, some whole and some broken, adding a rough, textured look. Pieces are cut into squares and triangles, scattered evenly with small crumbs around them. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use milk chocolate instead of white chocolate?

Yes, you can substitute milk chocolate but keep in mind the flavor and sweetness will change. Milk chocolate has a deeper cocoa flavor and may pair differently with the peanut butter and candy.

Why is vegetable oil added to the white chocolate?

The vegetable oil helps thin the white chocolate, making it easier to spread smoothly in the pan. It also helps achieve a better texture in the bark once set.
