Aunt Patty swore this was her 4 ingredient secret weapon for potlucks

This is my stripped-down, weeknight-friendly version of Aunt Patty’s legendary 4-ingredient potluck bars. She always called them her “secret weapon” because they disappeared faster than anything else on the dessert table, and I honestly thought she was exaggerating—until I watched a full ceramic dish of these vanish in minutes at a neighborhood cookout. They’re built on a thick, crumbly graham cracker and peanut butter base, then topped with a smooth layer of melted chocolate. With just graham cracker crumbs, peanut butter, butter, and chocolate chips, they’re perfect for busy days when you want something homemade, impressive, and ridiculously easy.
Serve these chocolate peanut butter bars chilled or at cool room temperature so the layers stay neat when you slice them. They pair perfectly with a cold glass of milk, hot coffee, or an after-dinner cup of tea. For potlucks or office parties, cut them into small squares or rectangles and arrange them in a single layer on a simple white platter so that smooth chocolate top really pops. If you’re hosting at home, set the ceramic baking dish right on the counter or table—the mottled granite and casual presentation somehow make them feel even more comforting and nostalgic.
