Tips

Tip 1

Use a well-seasoned or pre-greased cast iron skillet to prevent sticking.

Tip 2

Fold chocolate chips gently to maintain their shape.

Tip 3

Check cookie at 15 minutes; bake until edges are set but center remains slightly soft.

Good to Know

Storage

Cover cooled cookie and refrigerate up to 2 days. Reheat gently before serving.

Make Ahead

Prepare batter up to 2 hours ahead; pour into skillet and bake when ready.

Serve With

Serve warm from skillet topped with sea salt and a scoop of ice cream.

Common Mistakes

Watch

Overbake to avoid a dry, cakey texture; pull from oven when edges are set but center still appears slightly underbaked.

Watch

Use room-temperature egg to avoid lumpy batter when whisking with cold butter and oil.
