Step-by-Step Instructions

1. Prepare the Cake Layers

Preheat your oven to 350°F (175°C) and grease three 8-inch round cake pans. Line the bottoms with parchment paper for easy removal.

In a medium bowl, whisk together flour, baking powder, baking soda, and salt.

In a large mixing bowl, beat the butter and sugar together for 2–3 minutes until light and fluffy. Add eggs one at a time, then mix in vanilla.

Alternate adding the dry ingredients and buttermilk, beginning and ending with dry ingredients. Mix only until just combined.

Divide the batter evenly between the pans and smooth the tops. Bake for 25–30 minutes, or until a toothpick inserted in the center comes out clean.

Cool in pans for 10 minutes before transferring to wire racks to cool completely.

2. Make the Edible Cookie Dough

To make flour safe to eat, spread it on a parchment-lined baking sheet and bake at 350°F for 5–6 minutes, then let it cool completely.

In a bowl, beat the butter, brown sugar, and granulated sugar until smooth. Mix in milk and vanilla, then add cooled flour and chocolate chips.

Chill for about 20 minutes until slightly firm. Use half for the filling and roll small balls with the rest to decorate the top.

3. Make the Brown Sugar Buttercream

Beat butter and brown sugar together for 2 minutes until creamy and light.

Add powdered sugar gradually, mixing after each addition. Pour in cream, vanilla, and a pinch of salt, then beat 2–3 more minutes until smooth and fluffy. Fold in chocolate chips at the end.

4. Make the Chocolate Ganache

In a small saucepan, warm the heavy cream until just simmering (don’t boil). Pour over chopped chocolate and let sit for 2 minutes before stirring until smooth and glossy.

Let it cool until thick but still pourable, it should drip slowly from a spoon.

5. Assemble the Cake

Place one cooled cake layer on a cake stand or plate. Spread a thin layer of buttercream over the top, then spoon bits of cookie dough evenly over it. Press down gently.

Repeat with the second layer, then top with the final cake layer.

Frost the entire cake with the brown sugar chocolate chip buttercream, smoothing the sides and top.

Spoon the ganache around the top edge, letting it drip naturally down the sides.

Finish by sprinkling chocolate chips and decorating with cookie dough balls. Fill in the tip with cookie dough pieces.

Tips for Success

• Use room temperature ingredients. This helps everything mix evenly for a smoother batter and frosting.
  
• Don’t overmix the cake batter. Stop once the flour disappears, this keeps the crumb light and tender.
  
• Cool the cakes completely before assembling, or the frosting will melt.
  
• Adjust frosting texture. If it’s too thick, add a splash more cream; too thin, add more powdered sugar.
  
• Chill before slicing. Letting the cake sit in the fridge for 30–60 minutes before cutting helps it hold those beautiful layers.
  

Heat-Treating Flour for Cookie Dough

Raw flour can sometimes contain bacteria, so baking it briefly makes it safe to eat. Spread it evenly on a lined baking sheet and bake at 350°F for 5–6 minutes. Once it cools, you can safely use it in edible cookie dough recipes.

How to Store Cookie Dough Cake

This cake stays fresh covered in the refrigerator for up to 4–5 days. For the best texture, let slices come to room temperature before serving.

You can also freeze individual slices wrapped tightly in plastic wrap and stored in an airtight container for up to two months, just thaw overnight in the fridge.
