Ingredients
For the Peanut Butter Layer:
-
1 cup (250g) creamy peanut butter
-
1/2 cup (115g) unsalted butter, melted
-
2 cups (240g) powdered sugar
-
1 teaspoon vanilla extract
For the Chocolate Layers:
-
2 cups (340g) semi-sweet or dark chocolate chips
-
2 tablespoons (30g) coconut oil (divided)
Instructions
-
Prepare the Pan: Line an 8×8 inch (20×20 cm) square baking pan with parchment paper, leaving an overhang on the sides for easy removal.
-
Create the Peanut Butter Layer: In a large mixing bowl, combine the melted butter, creamy peanut butter, and vanilla extract. Stir until smooth and well combined. Gradually add the powdered sugar, mixing until a thick, crumbly dough forms. Press this mixture firmly and evenly into the bottom of the prepared baking pan.
-
Prepare the First Chocolate Layer: In a microwave-safe bowl, combine 1 cup (170g) of the chocolate chips with 1 tablespoon (15g) of the coconut oil. Microwave in 30-second intervals, stirring between each, until the chocolate is completely melted and smooth.
-
Assemble and Chill: Pour the melted chocolate over the peanut butter layer and use a spatula to spread it into an even layer. Place the pan in the refrigerator for about 20 minutes, or until the chocolate is just set.
-
Add the Top Chocolate Layer: Once the first chocolate layer is set, repeat the melting process with the remaining 1 cup (170g) of chocolate chips and 1 tablespoon (15g) of coconut oil. Pour this over the first chocolate layer and spread it smoothly.
-
Final Chill: Return the pan to the refrigerator and chill for at least 2 hours, or until completely firm.
-
Slice and Serve: Once firm, lift the bars out of the pan using the parchment paper overhang. Use a sharp knife to slice into 16 squares. For cleanest cuts, let the bars sit at room temperature for 10 minutes before slicing.
Tips
-
Consistency is Key: Ensure your butter is fully melted and mixed thoroughly with the peanut butter before adding the powdered sugar. The mixture should be thick but still pliable enough to press into the pan.
-
Getting Clean Cuts: To achieve perfect, clean-cut bars, wipe your knife blade with a hot, damp cloth between each cut.
-
Adjusting Sweetness: If you prefer less sweet bars, use natural peanut butter (just peanuts and salt) instead of a conventional brand, and reduce the powdered sugar by 1/4 cup.
-
Chocolate Choice: Use high-quality chocolate chips or a chopped chocolate bar for the best flavor and texture. Semi-sweet or dark chocolate provides a nice balance to the sweet peanut butter layer.
-
Even Layers: Take your time spreading both the peanut butter and chocolate layers to ensure they are uniform in thickness across the entire pan.
Storage and Reheating
-
Storage: Store the bars in an airtight container in the refrigerator for up to 2 weeks. Layer parchment paper between the bars to prevent them from sticking together.
-
Freezing: These bars freeze beautifully. Wrap individual bars in plastic wrap and place them in a freezer-safe container or bag for up to 3 months. Thaw in the refrigerator overnight or at room temperature for 30 minutes before serving.
-
Reheating: These bars are best served chilled or at cool room temperature. No reheating is necessary, as the chocolate will melt quickly.
Serving Suggestions
These bars are rich and satisfying, making them the perfect companion to a hot cup of coffee or a cold glass of milk. For an elevated dessert, serve a single bar alongside a scoop of vanilla bean ice cream and a drizzle of warm peanut butter sauce. They are also a fantastic addition to a dessert board, cookie platter, or lunchbox.
