Ingredients

For the Brownie Layer

1 cup unsalted butter
8 oz semi-sweet chocolate, chopped
1 1/4 cups granulated sugar
3/4 cup brown sugar
4 large eggs
1 tablespoon vanilla extract
1 cup all-purpose flour
1/4 cup cocoa powder
1/2 teaspoon salt

For the Edible Cookie Dough

(Made without eggs and with heat-treated flour for safety.)

1 cup all-purpose flour
1/2 cup unsalted butter, softened
3/4 cup brown sugar
1/4 cup granulated sugar
2–3 tablespoons milk
2 teaspoons vanilla extract
1/2 teaspoon salt
3/4 cup mini chocolate chips

For the Chocolate Ganache

3/4 cup heavy cream
6 oz semi-sweet chocolate, chopped

Optional garnish: extra chocolate chips or cookie dough crumbles.

How to Prepare Cookie Dough Brownie Cake

Step 1: Heat-Treat the Flour

Since the cookie dough will not be baked, this step is important.

Spread the flour on a baking sheet and bake at 350°F (175°C) for about 5 minutes, or until it reaches a safe temperature.

Let it cool completely before using.

Step 2: Prepare the Brownie Base

Preheat oven to 350°F (175°C).

Grease and line an 8-inch or 9-inch round pan with parchment paper.

Melt Chocolate and Butter

In a heatproof bowl, melt butter and chopped chocolate together until smooth. Stir until glossy.

Add Sugars

Whisk in granulated and brown sugars.

Incorporate Eggs

Add eggs one at a time, whisking well after each addition. Stir in vanilla.

The batter should look thick and shiny.

Fold in Dry Ingredients

Gently mix flour, cocoa powder, and salt into the batter until just combined.

Do not overmix — this keeps the brownies fudgy rather than cakey.

Step 3: Bake

Pour batter into the prepared pan and smooth the top.

Bake for 25–30 minutes.

A toothpick inserted should come out with moist crumbs, not wet batter.

Allow the brownie to cool completely before adding the cookie dough layer.

Warm brownies will melt the dough.

Make the Edible Cookie Dough

Step 4: Cream Butter and Sugars

Beat softened butter with brown sugar and granulated sugar until light and fluffy.

Step 5: Add Vanilla and Milk

Mix until smooth.

Step 6: Add Heat-Treated Flour and Salt

Stir until a soft dough forms.

Step 7: Fold in Chocolate Chips

Distribute evenly for chocolate in every bite.

If the dough feels too thick, add an extra tablespoon of milk.

Step 5: Assemble the Cake

Press the cookie dough evenly over the cooled brownie layer.

Use an offset spatula or your hands to create a smooth surface.

Chill for about 30–45 minutes to firm up before adding ganache.

Prepare the Ganache

Step 6: Heat the Cream

Warm the cream until steaming but not boiling.

Step 7: Melt the Chocolate

Pour cream over chopped chocolate and let sit for 2 minutes.

Stir until smooth and glossy.

Allow it to cool slightly so it thickens but remains pourable.

Step 8: Finish the Cake

Pour ganache over the cookie dough layer and gently spread to the edges.

Optional: decorate with chocolate chips or small cookie dough pieces.

Refrigerate for 1 hour until set.

Expert Tips for Bakery-Quality Results

Use High-Quality Chocolate

Better chocolate equals better flavor.

Do Not Overbake the Brownie

Slight underbaking keeps it fudgy.

Chill Between Layers

This helps create clean, defined layers.

Level the Cookie Dough

Even layers make slicing easier.

Cut with a Warm Knife

Dip in hot water and wipe dry for sharp edges.

Flavor Variations

Peanut Butter Cookie Dough

Add 1/2 cup creamy peanut butter to the dough.

Triple Chocolate

Stir white and dark chocolate chips into the cookie dough.

Salted Caramel

Drizzle caramel over the ganache and add a light pinch of flaky salt.

Cookies and Cream

Fold crushed chocolate sandwich cookies into the dough.

Nut Lover’s Version

Add chopped toasted walnuts or pecans.

Storage Tips

Refrigerator:
Store covered for up to 5 days.

Freezer:
Freeze slices individually for up to 2 months.
Thaw overnight in the refrigerator.

Common Mistakes to Avoid

Skipping Flour Heat-Treating

Important for edible dough safety.

Adding Dough to Warm Brownies

Causes melting and sliding layers.

Overbaking

Leads to dry brownies.

Pouring Ganache Too Hot

Can soften the cookie dough.

Serving Suggestions

Because this dessert is rich, moderate slices are best.

Serve with:

Cold milk
Coffee
Vanilla ice cream
Lightly whipped cream

For an elegant presentation, drizzle extra ganache on the plate before placing the slice.
