Ingredients

- Granulated sugar (¼ cup): Balances sweetness and contributes to crispy edges.
- Large egg (1): Binds ingredients while adding moisture and structure.
- Large egg yolk (1): Enhances softness and richness in the dough.
- Vanilla extract (2 teaspoons): Infuses sweet warmth and enhances chocolate flavor.
- All-purpose flour (2 cups): The base providing structure and body for the dough.
- Cornstarch (1 teaspoon): Softens the texture for a tender cake-like crumb.
- Baking soda (1 teaspoon): Leavens the dough, creating lightness and slight rise.
- Salt (½ teaspoon): Balances sweetness and enhances overall flavors.
- Chocolate chips (1½ cups): Semi-sweet or milk chocolate chips melt beautifully for rich pockets of chocolate throughout.
- Optional toppings: Chocolate frosting or buttercream, extra chocolate chips, and colorful sprinkles for decoration and added indulgence.
Instructions
- Preheat and Prepare Pan
-
Start by heating your oven to 180 °C (350 °F). Grease a 23 cm (9-inch) round cake pan or springform pan and line the bottom with parchment paper. This ensures the cookie cake releases easily and bakes evenly.
- Cream Butter and Sugars
-
In a large bowl, beat the softened butter with brown and granulated sugars until light and fluffy. This aerates the butter, helping create a soft texture and a well-mixed dough.
- Add Wet Ingredients
-
Mix the egg, extra egg yolk, and vanilla extract into the creamed butter mixture. These ingredients add moisture and deepen flavor, binding the dough components together.
- Combine Dry Ingredients
-
In a separate bowl, whisk together the flour, cornstarch, baking soda, and salt. This even distribution of leavening agents and seasoning ensures consistent texture in the baked cake.
- Mix Dry into Wet
-
Gradually add the dry ingredients into the wet mixture, stirring just until combined to avoid overmixing. Then gently fold in the chocolate chips, dispersing them evenly throughout the dough.
- Press Dough into Pan
-
Transfer the dough to the prepared pan and press it evenly across the bottom. Uniform thickness helps the cookie cake bake consistently, balancing the crispy edges with a soft center.
- Bake the Cookie Cake
-
Bake for 20 to 25 minutes until the edges are set and golden, but the center still looks slightly soft. This ensures a chewy, gooey middle and crisp edges.
- Cool and Transfer
-
Allow the cookie cake to cool in the pan for 15 to 20 minutes, then carefully transfer it to a serving plate. Cooling slightly helps the cake set for cleaner slices.
- Decorate and Serve
-
Top with chocolate frosting, extra chocolate chips, or sprinkles if desired. Slice into wedges and serve warm or at room temperature for the best texture and flavor.
- Underbaking slightly creates a soft, gooey center that contrasts beautifully with crisp edges.
- Smaller pans yield thicker, fudgier cookie cakes, so adjust baking time accordingly.
- Customize by adding nuts or white chocolate chips for varied textures.
- Store covered at room temperature up to 3 days or refrigerate to keep fresh up to 5 days.
- Dough can be made a day ahead and refrigerated for convenience.
Storage Tips
Keep your cookie cake covered tightly in an airtight container at room temperature to maintain softness for up to 3 days. For longer freshness, refrigerate it for up to 5 days, letting it come to room temperature before serving.
Serving Suggestions
Serve slices warm with a scoop of vanilla ice cream or a drizzle of caramel sauce. Accompany with coffee or milk for a classic indulgent treat perfect for celebrations or cozy nights in.
- Use softened butter, not melted, to achieve the best creamy texture in your dough.
- Try chilling the dough for 30 minutes before baking to improve flavor development and reduce spreading.
- For clean slices, warm the knife slightly before cutting the cookie cake.
FAQs
- Can I use different types of chocolate chips?
-
Yes, semi-sweet, milk chocolate, or a mix can be used depending on your taste preference.

- Can I freeze the cookie cake?
-
Yes, wrap tightly and freeze for up to 2 months. Thaw at room temperature before serving.
- Is it possible to make individual cookie cakes?
-
Absolutely! Divide dough into smaller pans or muffin tins and adjust baking time accordingly.
- What if I don’t have cornstarch?

You can omit it or replace with an equal amount of potato starch for a similar tender texture.
- How long does the dough last in the fridge?
-
Dough can be refrigerated safely for up to 24 hours before baking.
