• 1 cup (200g) granulated sugar
• 1 cup (200g) brown sugar
• 4 large eggs, room temperature
• 1 teaspoon vanilla extract
• 1 cup (125g) all-purpose flour
• 1 cup (90g) unsweetened cocoa powder
• 1/2 teaspoon salt

For the Cookie Dough Layer:

• 1 cup (225g) unsalted butter, softened
• 1 cup (200g) brown sugar
• 1/2 cup (100g) granulated sugar
• 2 tablespoons milk (or almond milk)
• 1 teaspoon vanilla extract

• 1 cup (175g) mini chocolate chips

For the Chocolate Topping:

• 1 cup (175g) semi-sweet chocolate chips

Pro Tip: Heat-treating the flour for the cookie dough layer ensures it’s safe to eat raw. Simply microwave the flour in 30-second intervals until it reaches 160°F (71°C).

Equipment Needed

You don’t need fancy tools to whip up these indulgent slices. Here’s what you’ll need:

• Mixing bowls: At least three medium-sized bowls for preparing each layer.
• Whisk: For mixing the brownie batter and cookie dough.
• Spatula: Helps to spread each layer evenly.
• 9×13-inch baking pan: Perfect for layering and baking the brownie base.
• Microwave-safe bowl: For melting the chocolate topping.

Tip: If you don’t have a 9×13-inch pan, use two smaller pans and divide the batter evenly. Adjust baking time as needed.

Preparation Method

1. Preheat your oven: Set it to 350°F (175°C) and grease your 9×13-inch baking pan. Line it with parchment paper for easy removal.
2. Make the brownie layer: In a mixing bowl, whisk together melted butter, granulated sugar, and brown sugar until smooth. Add eggs and vanilla extract, whisking until combined. Sift in the flour, cocoa powder, and salt, then fold gently until no dry streaks remain. Pour the batter into the prepared pan and spread evenly. Bake for 25-30 minutes. Allow to cool completely.
3. Prepare the cookie dough layer: In another bowl, beat the softened butter, brown sugar, and granulated sugar until creamy. Mix in milk and vanilla extract. Gradually add the heat-treated flour and salt, stirring until fully combined. Fold in mini chocolate chips. Spread the cookie dough evenly over the cooled brownie layer.
4. Make the chocolate topping: In a microwave-safe bowl, melt the chocolate chips and butter in 20-second intervals, stirring until smooth. Pour the melted chocolate over the cookie dough layer and spread evenly.
5. Chill and slice: Place the pan in the refrigerator for at least 1 hour to set. Once firm, remove from the pan, slice into squares or rectangles, and enjoy!

Cooking Tips & Techniques

Here are some tips to ensure your Cookie Dough Brownie Cake Slices turn out perfect every time:

• Don’t overmix the brownie batter: Overmixing can lead to dense brownies. Stir just until combined.
• Cool the brownie layer completely: If the brownie isn’t fully cool, the cookie dough layer may melt and become messy.
• Use heat-treated flour: Ensures the cookie dough layer is safe to eat raw.
• Chill before slicing: Cooling the dessert in the fridge makes it easier to get clean, sharp edges when cutting.
• Experiment with toppings: Sprinkle sea salt or crushed nuts on the chocolate layer for added texture and flavor.

Variations & Adaptations

Want to mix things up? Here are some fun ways to customize your Perfect Cookie Dough Brownie Cake Slices:

• Peanut butter twist: Replace some of the butter in the cookie dough layer with creamy peanut butter for a nutty flavor.
• Gluten-free option: Use almond flour or your favorite gluten-free flour blend for both the brownie and cookie dough layers.
• Seasonal spin: Add crushed candy canes to the chocolate topping for a festive holiday treat.
• Vegan adaptation: Swap out the butter with vegan butter, eggs with flax eggs, and use dairy-free chocolate chips for a plant-based version.

Serving & Storage Suggestions

These slices are best served chilled or at room temperature. Here are some ways to enjoy them:

• Presentation: Arrange slices on a dessert platter and drizzle with extra melted chocolate for a polished look.
• Pairings: Serve with a scoop of vanilla ice cream or a glass of cold milk for the ultimate indulgence.
• Storage: Keep the slices in an airtight container in the refrigerator for up to 5 days.
