Line a 9x13-inch baking pan with parchment paper or lightly grease it to prevent sticking.
In a medium saucepan over low heat, melt the unsalted butter and the peanut butter together. Stir frequently until smooth and well combined.
Remove the saucepan from heat and stir in the powdered sugar and graham cracker crumbs until the mixture forms a thick dough-like consistency.
Press the peanut butter mixture evenly into the prepared baking pan, smoothing it out with the back of a spoon or an offset spatula.
In a microwave-safe bowl, melt the semisweet chocolate chips and 1/4 cup of peanut butter together in 30-second intervals, stirring after each interval, until smooth and glossy.
Pour the melted chocolate mixture over the peanut butter layer in the pan. Spread it evenly to cover the entire surface.
Refrigerate the pan for at least 2 hours, or until the chocolate has fully set.
Once fully set, remove the pan from the fridge and let it sit at room temperature for 5 minutes to make cutting easier.
Lift the peanut butter square block out of the pan using the parchment paper (if used) and place it on a cutting board.
Cut into 24 squares and serve. Store leftovers in an airtight container in the refrigerator for up to a week.
