Ingredients

3/4 cup unsalted butter, softened. Softened butter creams easily with sugar and helps create a tender crumb.
1 cup packed brown sugar. Adds deep caramel flavor and chewiness.
1 large egg. Binds the dough and helps with structure.
1 egg yolk. Adds extra richness and chewiness.
2 teaspoons pure vanilla extract. Boosts overall flavor and aroma.
2 cups all-purpose flour. The base of the dough, provides structure.
2 teaspoons cornstarch. Helps keep the cake soft and slightly tender.
1 teaspoon baking soda. Leavens slightly for a light texture.
1/2 teaspoon salt. Balances sweetness and enhances flavor.
1 and 1/2 cups semi-sweet chocolate chips. For pockets of melted chocolate throughout.
Optional: chocolate buttercream for topping. Use this to make the cake look festive or to add a creamy finish.

Step-by-step Instructions

Preheat your oven to 350°F (177°C) and spray a 9-inch pie dish or cake pan with nonstick spray. Make sure the pan is evenly coated so the cake releases easily.
In a large bowl, beat together the softened butter and packed brown sugar until creamy and well combined. Scrape the bowl sides so everything mixes evenly.
Add the egg, egg yolk, and vanilla extract, and mix until thoroughly combined. Mix until smooth, about 30 seconds.
In another bowl, whisk together the flour, cornstarch, baking soda, and salt. Whisking removes lumps and helps distribute the leavening.
Gradually add the dry ingredients to the wet ingredients and mix until just combined, being careful not to overmix. A few streaks of flour are okay, you want a soft dough.
Fold in the chocolate chips. Reserve a tablespoon of chips to press on top if you like a decorative finish.
Press the cookie dough mixture into the prepared pan. Press evenly so the cake bakes uniformly; a light layer of dough across the surface prevents thin spots.
Bake in the preheated oven for 22 to 26 minutes until a toothpick comes out clean or with moist crumbs. Start checking at 22 minutes to avoid overbaking.
Let the cake cool completely on a cooling rack before frosting with chocolate buttercream if desired. Cooling fully helps the cake set so slices hold their shape.

For a slightly different texture or appearance, you can borrow techniques from other cookie recipes, like the chewy centers in some chocolate crinkle cookies.

Tips, Storage & Variations

Tips

Measure flour by spooning it into the cup and leveling with a knife to avoid a dense cake.
Do not overmix after adding flour. Overmixing can make the crumb tough.
If the edges brown too quickly, tent with foil for the last few minutes of baking.

Storage

Room temperature: Store in an airtight container for up to 3 days.
Refrigerator: Keep covered for up to 1 week, especially if frosted.
To reheat: Warm individual slices in a 300°F oven for 5 to 8 minutes or in the microwave for 10 to 15 seconds for a fresh-baked feel.

Freezing

Unfrosted: Wrap tightly in plastic wrap and freeze for up to 3 months. Thaw overnight in the refrigerator before bringing to room temperature.
Frosted: Freeze without frosting, then frost after thawing for best texture.

Extra chocolate: Increase the chocolate chips to 2 cups for a more chocolate-forward cake.
