Grandma Doris always called this her 4 ingredient sweet and salty secret. I finally learned her trick and the pan disappears from the picnic table in

Pan of caramel pretzel bars on a kitchen counter

Serve these caramel pretzel bars slightly warm or at room temperature so the caramel stays soft but sliceable. I like to cut them into small squares for picnics and potlucks and pile them onto a simple white platter to show off the chocolate swirls. They pair well with hot coffee, black tea, or a cold glass of milk, and they’re especially good alongside something tart and fresh, like sliced strawberries
