01 - Preheat your oven to 350°F (175°C). Lightly grease a 10-inch (25 cm) oven-safe skillet with butter or nonstick spray.
02 - In a medium bowl, whisk together the flour, baking soda, and fine sea salt.
03 - In a large bowl, whisk the melted butter, brown sugar, and granulated sugar until smooth and slightly lightened in color. Incorporate the eggs and vanilla, whisking until well combined.
04 - Gradually fold the dry ingredients into the wet mixture using a spatula. Mix just until no dry streaks remain.
05 - Gently fold in the chocolate chips and cherries. Avoid overmixing to maintain texture.
06 - Spread the dough evenly into the prepared skillet. Sprinkle the top evenly with flaky sea salt.
07 - Bake for 22 to 25 minutes, or until the edges are golden brown and the center is just set but still soft. Do not overbake; a gooey center is desired.
08 - Allow the skillet cookie to cool for 10 to 15 minutes before serving warm, ideally accompanied by vanilla ice cream.
