Ultimate Cookie Dough Brownie Cake Tips, FAQ & printable recipe

Tips for success

For the cleanest slices, use a long, sharp knife and wipe it between cuts. Dipping the knife in hot water and drying it before each slice helps the knife glide through the ganache without dragging.

If the cake is too soft, chill it for 15 minutes before slicing. Serve at room temperature for the fullest flavor, but keep leftovers in the fridge.

Make the cake ahead of time and store it in the refrigerator for up to 3 days. The flavors meld and the texture becomes even more fudgy. If you prefer a firmer ganache, use a higher ratio of chocolate to cream.

For a more dramatic drip, pour the ganache when it's slightly warmer and thinner. Experiment with different chocolate chips or add chopped nuts for extra crunch.

Variations

• Peanut Butter Swirl: Before baking the brownie layers, drop spoonfuls of peanut butter into the batter and swirl with a knife. Add a layer of peanut butter frosting instead of cookie dough for a different twist.
• Mint Chocolate: Add 1/2 teaspoon peppermint extract to the brownie batter and stir 1/2 cup crushed chocolate-mint candies into the cookie dough. Use mint chocolate chips in the ganache for a refreshing flavor.
• Salted Caramel: Drizzle caramel sauce over the brownie layers before adding the cookie dough. Sprinkle flaky sea salt over the ganache just before it sets. The salty-sweet combination is irresistible.
• Gluten-Free: Use a gluten-free brownie mix and replace the all-purpose flour in the cookie dough with a 1:1 gluten-free flour blend. Ensure all other ingredients are certified gluten-free.

Storage and make-ahead

Fridge

Store in an airtight container in the refrigerator for up to 5 days. Let stand at room temperature for 15 minutes before serving.

Freezer

Wrap the fully assembled cake (or individual slices) tightly in plastic wrap and foil. Freeze for up to 3 months. Thaw overnight in the refrigerator.

Reheat

For a warm, gooey treat, microwave a slice for 10-15 seconds. Be careful not to overheat or the ganache may melt.

Store leftover cake in an airtight container in the refrigerator for up to 5 days. Let it come to room temperature before serving for the best texture and flavor. If you prefer a chilled, fudgy texture, enjoy it straight from the fridge.

The brownie layers can be baked a day ahead and stored wrapped in plastic wrap at room temperature. The cookie dough can be made up to 3 days in advance and kept refrigerated. The ganache can be made a day ahead and reheated gently before assembling. Assemble the cake up to 24 hours before serving and keep it refrigerated.

Serving ideas

This cake is a celebration on its own, but it pairs beautifully with a scoop of vanilla ice cream or a drizzle of caramel sauce.

The cold, creamy ice cream contrasts with the dense brownie and chewy cookie dough, making each bite even more indulgent. For a special touch, add a sprinkle of flaky sea salt on top to balance the sweetness.

Serve the cake as the centerpiece of a birthday party, holiday gathering, or any occasion that calls for a memorable dessert. Cut generous slices and present them on dessert plates.

A glass of cold milk or a cup of coffee is the perfect accompaniment. Leftovers can be enjoyed cold or warmed briefly in the microwave for a gooey treat.

Ultimate Cookie Dough Brownie Cake

Prep 30 minCook 45 minRest 30 minTotal 1 h 45 minServes 12

Ingredients

• 1 box family-size brownie mix (for 9x13-inch pan)
• 2 large eggs
• 1/2 cup vegetable oil
• 1/4 cup water
• 1/2 cup unsalted butter, softened
• 3/4 cup packed light brown sugar
• 1/4 cup granulated sugar
• 2 tsp vanilla extract
• 1 1/2 cups all-purpose flour
• 1/2 tsp salt
• 3/4 cup semisweet chocolate chips
• 1 1/2 cups heavy cream
• 12 oz semisweet or dark chocolate, finely chopped
• 1/4 cup mini chocolate chips

Instructions

1. Preheat the oven to 350°F (175°C). Grease two 9-inch round cake pans and line the bottoms with parchment paper. Prepare the brownie mix according to package directions using the eggs, oil, and water. Divide the batter evenly between the prepared pans and smooth the tops. Bake until a toothpick inserted in the center comes out with a few moist crumbs, about 25 to 30 minutes. Let the brownies cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.
2. In a large bowl, beat the softened butter, brown sugar, and granulated sugar together until light and fluffy. Beat in the vanilla extract. Reduce the mixer speed to low and gradually add the flour and salt, mixing until just combined. Fold in the semisweet chocolate chips. Press the cookie dough into a 9-inch round cake pan lined with plastic wrap, smoothing the top. Refrigerate for at least 30 minutes until firm.
3. Place the chopped chocolate in a heatproof bowl. Heat the heavy cream in a small saucepan over medium heat until it just begins to simmer. Pour the hot cream over the chocolate and let it sit for 2 minutes. Gently stir until smooth and glossy. Let the ganache cool slightly until it thickens to a pourable consistency, about 10 minutes.
4. Place one brownie layer on a serving plate. Spread a layer of ganache over it, then place the chilled cookie dough disc on top. Press gently to adhere. Place the second brownie layer on top. Pour the remaining ganache over the cake, letting it drip down the sides. Use an offset spatula to smooth the top and sides if desired.
5. Sprinkle the mini chocolate chips over the top of the cake. Let the cake set at room temperature for about 20 minutes, or refrigerate for 10 minutes to speed up the process. Slice and serve.
