A quick and comforting single-serving skillet cookie with a gooey center and crispy edges, perfect for solo indulgence or last-minute desserts.
Do not overbake; the center should remain slightly underbaked for gooeyness. Use egg yolk only for a tender texture. Cast iron skillet provides best crispy edges. For dairy-free, substitute coconut oil for butter and dairy-free chocolate chips. Dough can be refrigerated up to 24 hours before baking.
