Ingredients
- 1 cup creamy peanut butter
- 1/2 cup (1 stick) unsalted butter
- 1 cup packed brown sugar
- 1 tsp vanilla extract
- 2 cups rolled oats
- 1 1/2 cups bittersweet chocolate chips
- 1/4 tsp salt
Instructions
- Step 1: Line an 8-inch square baking pan with parchment paper, leaving edges overhanging for easy removal later. Preheat oven to 350°F and spread 2 cups of rolled oats on a baking sheet; toast in the oven for 10 minutes until golden and fragrant, stirring halfway through.
- Step 2: In a medium saucepan, combine 1 cup creamy peanut butter, 1/2 cup unsalted butter, 1 cup packed brown sugar, and 1/4 tsp salt over medium heat. Stir constantly until butter melts and sugar dissolves, about 3-4 minutes. Remove from heat and stir in 1 tsp vanilla extract.
- Step 3: Immediately fold the toasted oats into the peanut butter mixture until evenly coated. Press this mixture firmly into the prepared pan in an even layer.
- Step 4: In a microwave-safe bowl, melt 1 1/2 cups bittersweet chocolate chips in 30-second intervals, stirring each time, until smooth and glossy. Pour the chocolate over the oat layer and spread evenly with a spatula.
- Step 5: Refrigerate the pan for at least 2 hours until the bars are set and firm. Use the parchment paper edges to lift the bars out, then cut into 12 squares and serve chilled.
