This is such a great cake for the cookie dough lover in your life. It’s rich, soft, chocolatey, and topped with a thick layer of edible cookie dough and silky chocolate ganache.

The cake itself is tender and deeply chocolatey from cocoa, espresso powder, and hot coffee. Then you get that nostalgic brown sugar cookie dough layer with chocolate chips, plus a glossy ganache finish. It’s truly one of the best celebration cakes I’ve made in a while.

Enjoy!

This cake is made of:

Deeply Chocolatey Base: Made with cocoa, espresso powder, and hot coffee for a tender, rich crumb.
Nostalgic Cookie Dough Layer: A thick, chewy, brown sugar-infused edible cookie dough packed with chocolate chips.
Bakery-Style Finish: Topped with a silky, glossy chocolate ganache that sets beautifully.
Perfect for Celebrations: An impressive showstopper that balances rich chocolate with classic cookie dough flavors.

Prep for Success

Heat-Treat the Flour: Safe consumption of edible cookie dough requires heat-treating the raw flour beforehand.
Cooling Components: Ensure the baked chocolate cake and the heat-treated flour are completely cooled before assembly.
Room Temperature Ingredients: Pull the butter for the cookie dough, the egg, the egg yolk, and the buttermilk ahead of time to ensure flawless mixing.

Secrets for the perfect result every time:

The Coffee Trick: Using hot coffee or hot water blooms the cocoa powder, which intensifies the chocolate flavor and thins out the thick initial batter into a smooth, glossy consistency.
Ganache Consistency: Let the hot heavy cream sit on the chocolate undisturbed for 1–2 minutes before whisking to ensure a perfectly smooth, emulsified finish without breaking.
Serving Temperature: For the absolute best texture, serve this cake chilled or slightly softened at room temperature. The cake stays soft, the cookie dough layer gets thick and chewy, and the ganache maintains its gorgeous finish.

115 g all-purpose flour
200 g granulated sugar
55 g cocoa powder
1 tsp baking soda
½ tsp baking powder
½ tsp salt
1 tsp instant coffee, powdered
125 g buttermilk
80 g unsalted butter, melted
1 tsp honey
1 large egg

½ tbsp vanilla extract
120 ml hot water or hot coffee

Edible Cookie Dough Ingredients

178 g unsalted butter, room temperature
1 tsp honey
150 g light brown sugar
40 g granulated sugar
215 g heat-treated all-purpose flour, cooled
½ tsp salt
1 tbsp vanilla bean paste, or seeds from 1 vanilla bean
130 g dark chocolate chips

Chocolate Ganache Ingredients

200 g dark chocolate
200 g heavy cream

Make the Chocolate Cake

Preheat oven to 350°F and line an 8-inch cake pan with parchment paper.
In a bowl, combine the flour, sugar, cocoa powder, baking soda, baking powder, salt, and instant coffee powder. Whisk until fully combined.
Add the buttermilk, egg, egg yolk, melted butter and honey.
Whisk until the batter is just barely combined. It will look thick at this stage.
Add the hot coffee or hot water, along with the vanilla.
Whisk until a smooth, glossy batter forms.
Pour the batter into the prepared pan.
Bake for 40–45 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs.
Remove from the oven and cool completely before assembling.

Make the Edible Cookie Dough

In a bowl, cream together the butter, honey, light brown sugar, and granulated sugar until light, fluffy, and smooth.
Add the vanilla bean paste or vanilla bean seeds and mix again.
Add the heat-treated flour and salt.
Mix until a soft cookie dough forms.
Fold in the chocolate chips.
Set aside until ready to assemble.

Make the Ganache

Add the chocolate to a heatproof bowl.
Heat the heavy cream until steaming.
Pour the hot cream over the chocolate and let it sit for 1–2 minutes.
Whisk until smooth, glossy, and fully combined.
Let the ganache cool slightly until thick but still spreadable.

Assemble

Place the cooled chocolate cake onto a serving plate or cake board.
Spread the edible cookie dough evenly over the top of the cake.
Pour or spread the ganache over the cookie dough layer.
Chill until the ganache is set.
Slice and enjoy.

Notes

To heat-treat flour, spread it onto a baking sheet and bake at 350°F for about 5 minutes, then cool completely before using.

This cake is best served chilled or slightly softened at room temperature. The chocolate cake stays soft, the cookie dough layer gets thick and chewy, and the ganache gives it the prettiest bakery-style finish.

Q&A:

Why do I need to heat-treat the flour for the cookie dough?

Raw flour can harbor bacteria, so baking it at 350°F for about 5 minutes ensures it is completely safe to consume without baking the finished dough. Always let it cool completely before mixing it into your butter and sugar.

Can I use hot water instead of hot coffee in the cake?

Yes! You can use either hot water or hot coffee. Hot coffee is highly recommended because it deepens and intensifies the chocolate flavor of the cocoa powder without making the cake taste like coffee.

How should I store this cake?

This cake is best stored in the refrigerator because of the fresh heavy cream in the ganache layer. It tastes incredible chilled or when allowed to sit at room temperature for a few minutes to soften slightly before slicing.
