Pull the skillet off the coals and cut in. Hazelnut Espresso Skillet Brownies come out with crisp, dark edges and a soft, fudgy center that steams when you break through the top. The espresso adds a clean roast note that keeps the chocolate from tasting flat, and toasted hazelnuts bring that welcome crunch you can hear around the picnic table.
Cast iron makes this an easy win at camp because it holds steady heat and rewards patience. Let your fire burn down to an even coal bed, set the skillet over gentle heat, and use a lid (or foil) to keep warmth moving across the surface. Rotate the pan now and then to dodge hot spots, and you’ll get an even bake without babysitting.
For easy cleanup, oil the skillet well or slip in a parchment round if it fits your pack. Serve warm and slice straight from the pan while everyone’s still lingering by the fire—coffee alongside is perfect, but any late-night thermos drink will do.
