- ½ cup all-purpose flour
- ¼ teaspoon baking soda
- ¼ teaspoon salt
- ¼ cup granulated sugar
- ¼ cup light brown sugar, packed
- 1 teaspoon vanilla extract
- 1/4 cup (4 tablespoons) butter, melted
- 1 large egg yolk
- ½ cup semi-sweet or dark chocolate chips
- Vanilla ice cream, for serving
Preheat oven to 350°F and grease 2 (4.5-inch) mini cast-iron skillets.
Combine the flour, baking soda and salt in a small bowl and mix well.
Combine the granulated sugar, brown sugar and vanilla extract in a separate mixing bowl.
Add the melted butter to the sugar mixture and mix until combined. Add the egg yolk and mix until combined.
Carefully stir the flour mixture into the wet ingredients until just combined. Stir in the chocolate chips. Press the dough into the skillets until evenly distributed.
Bake for 18–20 minutes, until edges are browned and a toothpick stuck into the center comes out clean.
Let stand for 5 minutes before garnishing with the ice cream and enjoy!
