Instructions

Step 1: In a medium saucepan, combine 1 cup creamy peanut butter and 1/2 cup unsalted butter over low heat. Stir continuously until melted and smooth, about 3 minutes.
Step 2: Remove from heat and whisk in 2 cups powdered sugar and 1 1/2 cups graham cracker crumbs until fully incorporated and thick.
Step 3: Press the peanut butter mixture evenly into a 9x9 inch lined baking pan using the back of a spoon.
Step 4: In a microwave-safe bowl, combine 1 1/2 cups semisweet chocolate chips and 2 tbsp vegetable oil. Microwave in 30-second intervals, stirring each time until smooth and glossy.
Step 5: Pour the melted chocolate over the peanut butter base and spread evenly with an offset spatula.
Step 6: Quickly press 1/4 cup mini candy eyes into the chocolate layer to create spooky faces. Refrigerate the bars for at least 2 hours until firm before cutting into squares.
