Ingredients

Unsalted butter: ¾ cup softened butter adds rich flavor and creates a tender, moist crumb.
Brown sugar: ¾ cup packed brown sugar provides deep caramel notes and moisture to the dough.
Granulated sugar: ¼ cup contributes sweetness and helps achieve a crisp edge.
Large egg: 1 egg binds ingredients and adds structure to the cookie cake.
Large egg yolk: 1 yolk adds extra richness and chewiness to the center.
Vanilla extract: 2 teaspoons enriches flavor with warm, aromatic notes.
All-purpose flour: 2 cups provides the structure needed while keeping the cookie soft.
Cornstarch: 1 teaspoon lightens the texture to ensure a tender bite.
Baking soda: 1 teaspoon helps the cookie cake rise and develop a slight chew.
Salt: ½ teaspoon balances sweetness and enhances flavors.
Chocolate chips: 1½ cups semi-sweet or milk chocolate chips add melty pockets of chocolate.

Instructions

Preheat and Prepare Pan: Set your oven to 180 °C (350 °F) to reach the ideal baking temperature. Grease a 9-inch (23 cm) round cake or springform pan and line the bottom with parchment paper to prevent sticking and ensure easy removal after baking.
Cream Butter and Sugars: In a large mixing bowl, beat the softened butter with brown and granulated sugars until the mixture becomes light, fluffy, and pale in color. This aeration step is key for a soft texture and helps dissolve the sugars evenly.
Add Wet Ingredients: Incorporate the whole egg, egg yolk, and vanilla extract into the creamed mixture. Beat until everything is well combined; the eggs add moisture and binding properties critical for the cookie cake’s structure.
Whisk Dry Ingredients: In a separate bowl, mix the flour, cornstarch, baking soda, and salt. This ensures the leavening agents and seasoning are distributed evenly to avoid clumping or uneven rising.
Combine Wet and Dry Mixtures: Gradually add the dry ingredients to the wet mixture, stirring gently just until combined. Overmixing can make the cookie cake dense. Fold in the chocolate chips carefully to distribute them evenly throughout the batter.
Press Dough into Pan and Bake: Evenly press the cookie dough into the prepared pan to ensure uniform thickness. Bake in the preheated oven for 20–25 minutes until the edges are set and golden, while the center remains soft for a gooey texture.
Cool Before Serving: Allow the cookie cake to cool in the pan for 15–20 minutes. This resting time lets it firm up for easy slicing and helps the flavors meld. Then transfer it onto a serving plate.
Decorate and Serve: Optionally, frost the top with chocolate or buttercream frosting and sprinkle extra chocolate chips or colorful sprinkles for a festive touch. Serve slightly warm or at room temperature for the best flavor and texture experience.

You Must Know

Underbaking slightly keeps the center irresistibly chewy and soft.
Using a smaller pan results in a thicker and gooier cookie cake.
Adding nuts or white chocolate chips offers delicious flavor variations.
Dough can be refrigerated up to 24 hours before baking without losing quality.

Storage Tips

Store your cookie cake covered at room temperature for up to 3 days to maintain freshness. For longer storage, refrigerate for up to 5 days and bring to room temperature before serving to restore softness.

Serving Suggestions

Pair this cookie cake with a cold glass of milk or a scoop of vanilla ice cream for a delightful dessert. It also works wonderfully as a celebratory centerpiece adorned with candles or festive decorations.

Professional Tips

Use room temperature butter for easier creaming with sugars.
Line the pan with parchment for smooth release and clean edges.
Don’t overmix the batter to retain a tender crumb and gooey center.

FAQs

Can I use other types of chocolate chips?: Yes, white chocolate, dark chocolate, or flavored chips like peanut butter work well. Adjust quantity based on preferred sweetness.
