Big Skillet Chocolate Chip Blondie

Makes 1 (10-inch) cookie cake. Recipe is from “Anne Byrn Saves the Day! Cookbook by Anne Byrn, reproduced by permission of Workman Publishing. Byrn says the cookie cake can be mixed, baked and served from the same pan; is a good choice for a potluck or a last-minute birthday party; and can be frozen.

12 tablespoons (3/4 cup, 11/2 sticks) unsalted butter

11/2 cups lightly packed light brown sugar

2 cups all-purpose flour

2 teaspoons baking powder

1/2 teaspoon salt

2 large eggs, beaten

1 teaspoon pure vanilla extract

1 cup semisweet chocolate chips

1/2 cup chopped pecans (optional)

Vanilla ice cream (optional), for serving

1. Place a rack in the center of the oven and preheat the oven to 350 F.

2. Place the butter in a 10-inch cast-iron skillet over low heat. Stir the butter until it melts, then stir the brown sugar into the butter until well combined. Remove the skillet from the heat.

3. Place the flour, baking powder, and salt in a small bowl and stir to mix. Spoon the flour mixture into the skillet with the butter and brown sugar and make a well in the center. Add the eggs and vanilla to the well and stir the flour mixture up and into the eggs until the mixture is smooth, 1 to 2 minutes. Fold in the chocolate chips. Scatter the pecans over the top, if desired.

4. Bake the cookie cake until the edge is lightly brown and the center is still a little soft to the touch, 22 to 26 minutes. Remove the skillet from the oven. Scoop the warm cookie cake into bowls and serve it with vanilla ice cream, if desired. Or let the cookie cake cool for about 1 hour, then cut into slices and serve on plates.

Do ahead: To take the cookie cake to a potluck or book club, carry it right in the skillet. Cover the skillet with aluminum foil or plastic wrap for transit. And if you are really thinking ahead, you can bake the cake several weeks before the event, remove it from the skillet, then freeze it well wrapped in aluminum foil and tucked in a resealable plastic bag. Thaw on the kitchen counter for 2 to 3 hours.
