Ingredients You’ll Need

To make this classic chocolate chip cookie cake, gather the following ingredients:

For the Cookie Cake:

• 3/4 cup unsalted butter, softened
  
• 1 cup packed brown sugar
  
• 1/4 cup granulated sugar
  
• 1 large egg + 1 egg yolk
  
• 1 tbsp vanilla extract
  
• 2 cups all-purpose flour
  
• 2 tsp cornstarch (this adds extra softness)
  
• 1/2 tsp baking soda
  
• 1/2 tsp salt
  
• 1 1/2 cups semisweet or milk chocolate chips
  
• Optional: 1/4 cup rainbow sprinkles or mini M&Ms for a fun, colorful touch!
  

For the Frosting (optional for decorating):

• 1/2 cup unsalted butter, softened
  
• 1 1/2 cups powdered sugar
  
• 2 tbsp heavy cream or milk
  
• 1 tsp vanilla extract
  
• Pinch of salt
  
• Food coloring + sprinkles for flair!
  

Step-by-Step Instructions

1. Preheat and Prepare Your Pan

Begin by preheating your oven to 350°F (175°C). Grease a 9-inch round cake pan or a springform pan, then line the bottom with parchment paper. This will make removing the cookie cake easier after baking and prevent sticking.

2. Make the Cookie Dough

In a large mixing bowl, cream together the softened butter, brown sugar, and granulated sugar. Beat this mixture for about 2 to 3 minutes until it’s light and fluffy — this step is key for a tender texture.
Next, add the egg, egg yolk, and vanilla extract. Mix until everything is fully combined.

In a separate bowl, whisk together the all-purpose flour, cornstarch, baking soda, and salt. Slowly add these dry ingredients to the wet ingredients, mixing just until combined. Overmixing can make the cookie cake tough, so be gentle.
Finally, fold in the chocolate chips along with the optional rainbow sprinkles or mini M&Ms for that fun birthday vibe.

3. Shape and Bake

Press the cookie dough evenly into the prepared pan. Use a spatula or your fingers to spread the dough all the way to the edges, ensuring an even thickness throughout.
Bake in the preheated oven for 20 to 25 minutes. Look for golden-brown edges and a center that is just set but still soft. Keep a close eye as overbaking will dry it out — the cookie cake will continue to cook a bit after you remove it from the oven.
Let the cookie cake cool completely in the pan before attempting to frost or slice.

4. Optional Frosting for Decorating

If you want to add a festive touch, whip up a simple buttercream frosting. Beat the softened butter until smooth and creamy. Gradually add the powdered sugar, heavy cream or milk, vanilla extract, and a pinch of salt. Beat everything until fluffy and light.
Add your favorite food coloring to match the party theme, and pipe the frosting around the edges or decorate the entire top. Sprinkle with colorful sprinkles for extra birthday cheer.

Pro Tips for the Perfect Chocolate Chip Cookie Cake

• Use cornstarch for softness: Adding 2 teaspoons of cornstarch to the dry ingredients is a little-known secret that makes your cookie cake softer and more tender, almost cake-like.
  
• Don’t overbake: Cookie cakes should have slightly golden edges and a center that’s just set. This keeps the inside soft and chewy.
  
• Customize your mix-ins: Feel free to swap the chocolate chips for chunks, white chocolate, nuts, or dried fruit. Adding rainbow sprinkles or mini M&Ms is perfect for birthdays and adds a festive pop of color.
  
• Double chocolate version: For chocolate lovers, replace 1/4 cup of the flour with cocoa powder and add an extra 1/4 cup chocolate chips. This variation is rich and indulgent.
  
• Serve warm with ice cream: For a gooey center, bake slightly less and serve slices warm with a scoop of vanilla ice cream on the side.
