Ingredients
For the Cookie Cake Base:
- 1 cup (2 sticks/227g) unsalted butter, softened to room temperature
- ¾ cup (150g) packed light or dark brown sugar
- ½ cup (100g) granulated sugar
- 1 large egg + 1 egg yolk, at room temperature
- 2 teaspoons pure vanilla extract
- 2 ¼ cups (281g) all-purpose flour
- 1 teaspoon cornstarch (for extra softness)
- 1 teaspoon baking soda
- 1 teaspoon salt
- 1 ½ cups (270g) semi-sweet chocolate chips
For the Chocolate Buttercream Frosting:
- 1 cup (2 sticks/227g) unsalted butter, softened
- 3 cups (360g) powdered sugar, sifted
- ½ cup (45g) unsweetened cocoa powder
- ¼ cup (60ml) milk or heavy cream
- 2 teaspoons vanilla extract
Ingredient Notes
Butter: Use unsalted butter and make sure it’s softened to room temperature. This helps it cream properly with the sugar, creating a light and fluffy texture.
Egg + Egg Yolk: The extra egg yolk is a key trick! It adds richness and makes the cookie cake incredibly chewy without making it cakey. For best results, ensure your eggs are at room temperature.
Cornstarch: This might seem unusual, but the cornstarch is a secret weapon that helps thicken the dough and create an exceptionally soft, melt-in-your-mouth texture. Don’t skip it!
Brown Sugar: This is essential for moisture and a deep, caramel-like flavor. You can use light or dark brown sugar.
Step-by-Step Instructions
1. Preheat and Prepare Your Pan
Preheat your oven to 350°F (177°C) . Spray a 9-inch round cake pan or pie dish with nonstick cooking spray. Lining the bottom with parchment paper can also help with easy removal.
2. Cream the Butter and Sugars
In a large bowl, use an electric mixer to beat the softened butter, brown sugar, and granulated sugar together on medium speed until the mixture is light, fluffy, and creamy, about 2-3 minutes.
3. Add Wet Ingredients
Beat in the whole egg, egg yolk, and vanilla extract on medium-high speed until combined. Scrape down the sides of the bowl as needed.
4. Combine Dry Ingredients
In a separate bowl, whisk together the flour, cornstarch, baking soda, and salt.
5. Mix the Dough
With the mixer on low speed, gradually add the dry ingredients to the wet ingredients. Mix until just combined. The dough will be thick. Fold in the chocolate chips with a spatula.
6. Press and Bake
Press the cookie dough evenly into your prepared pan. Bake for 22-28 minutes, or until the edges are golden brown and the center is set but still soft. A toothpick inserted in the center should come out with a few moist crumbs, not clean batter. The cookie will continue to bake as it cools.
7. Cool Completely
Place the pan on a cooling rack and let the cookie cake cool completely in the pan. This is a crucial step. Frosting a warm cookie will cause it to melt and slide off.
8. Make the Frosting
While the cake cools, prepare the frosting. In a medium bowl, beat the softened butter until smooth and creamy. Gradually add the powdered sugar and cocoa powder, mixing until well combined. Add the vanilla and milk and beat on high speed for 2-3 minutes until light and fluffy. Add more milk to reach your desired consistency.
9. Decorate and Serve
Once the cookie cake is completely cool, loosen the edges with a knife and transfer it to a serving plate. Frost with your chocolate buttercream, decorate with sprinkles, slice, and serve!
Expert Tips
- Don’t Overbake: The key to a soft, chewy cookie cake is to pull it from the oven when the center still looks slightly underdone. The edges should be set, but the center will have a slight jiggle. Overbaking will result in a dry, crumbly dessert.
- Cool Before Frosting: This is non-negotiable for a beautiful finish. If the cake is even slightly warm, the frosting will melt into a puddle.
- Room Temperature Ingredients: Taking the chill off your butter and eggs ensures they mix together smoothly, creating a uniform texture.
Variations
- Use Your Favorite Mix-Ins: Swap the semi-sweet chocolate chips for dark chocolate, milk chocolate, white chocolate, or peanut butter chips. M&Ms are another fun and colorful option!
- Make it a S’mores Cookie Cake: Add 1 cup of mini marshmallows and ½ cup of crushed graham crackers to the dough before baking.
- Change Up the Frosting: Try a simple vanilla buttercream, rich cream cheese frosting, or a drizzle of chocolate ganache for a different twist.
- Add Some Crunch: Fold in ½ cup of chopped walnuts, pecans, or macadamia nuts for added texture and flavor.
Storage Instructions
Store leftover cookie cake in an airtight container at room temperature for up to 3 days. You can also refrigerate it for up to 5 days, but let it come to room temperature before serving for the best texture.
Reheating Tips
For that “fresh from the oven” experience, you can reheat slices in a toaster oven or conventional oven at 300°F for 3-5 minutes. Avoid the microwave, as it can make the cookie cake soft and gummy.
Common Mistakes to Avoid
- Skipping the Cornstarch: This ingredient is the secret to a soft cookie cake, so try not to leave it out.
- Overmixing the Batter: Mix the dry ingredients just until combined. Overmixing develops the gluten in the flour, leading to a tough, dense cake.
- Not Greasing the Pan: Ensure your pan is well-greased so the cookie cake releases cleanly without breaking.
What to Serve With
A slice of this chocolate chip cookie cake is amazing on its own, but it’s even better with a scoop of vanilla ice cream, a dollop of whipped cream, or a drizzle of hot fudge sauce. A tall glass of milk is also the perfect partner for this giant cookie!
Frequently Asked Questions
Q: Can I use a different pan size?
A: Yes, but you’ll need to adjust the baking time. A 10-inch pan will yield a thinner cake that bakes faster (about 20-25 minutes), while a smaller pan will make a thicker cake that needs a few extra minutes.
Q: Do I need to refrigerate the dough?
A: No, one of the best parts of this recipe is that no chilling is required! However, if you want to make the dough ahead of time, you can cover and refrigerate it for up to 3 days before baking.
Q: How do I know when it’s done baking?
A: The edges should be beautifully golden brown, and the center should be set but still soft. A toothpick should come out with a few moist crumbs, not clean batter. Avoid overbaking!
Q: Can I freeze this cookie cake?
A: Yes! You can freeze the unfrosted cake for up to 3 months. Wrap it tightly in a layer of plastic wrap followed by a layer of foil. Thaw it at room temperature before frosting.
Q: Can I make this recipe vegan or gluten-free?
A: This specific recipe is designed for traditional baking, but you can experiment with a high-quality gluten-free 1:1 flour blend and use vegan butter and a flax “egg”.
Q: Why did my cookie cake turn out too dry?
A: This is almost always due to overbaking. Keep a close eye on the cake and pull it out when the center is still slightly soft, as the residual heat will continue to bake it.
