How to Make Oreo Crunch Bento Cake (Step-by-Step Recipe)

Follow these steps closely to achieve a bakery-quality result.

Step 1: Prepare the Cake Pans

Preheat oven to 350°F (175°C).
Grease two 8-inch round cake pans.
Line the bottoms with parchment paper for easy release.

Step 2: Make the Chocolate Cake Batter

In a large bowl, whisk together:
- Flour
- Cocoa powder
- Sugar
- Baking soda
- Baking powder
- Salt
In a second bowl, mix:
- Eggs
- Milk
- Oil
- Vanilla
Pour wet mixture into dry ingredients. Mix just until combined.
Carefully pour the hot water (or hot coffee) into the batter.
(This creates a silky batter and moist crumb.)

The batter will be thin—this is normal and ideal.

Step 3: Bake Your Cake Layers

Divide the batter evenly between the two pans.
Bake 28–32 minutes, or until a toothpick comes out clean.
Cool for 15 minutes in pans, then remove and cool completely.

Step 4: Make the Oreo Whipped Cream Filling

Beat the heavy cream until soft peaks form.
Add powdered sugar + vanilla.
Beat until stiff peaks form.
Gently fold in the crushed Oreos.

This filling stays light, fluffy, and perfectly textured.

Step 5: Assemble the Cake

Place the first layer on a cake board.
Spread a thick layer of Oreo whipped cream.
Sprinkle extra Oreo crumbs over the filling for crunch.
Add the second cake layer on top.
Frost the sides and top with whipped cream OR leave semi-naked for bento style.

Step 6: Add Chocolate Drip & Oreo Crunch

Heat chocolate + heavy cream until melted and smooth.
Let it cool slightly.
Drip along edges of the cake using a spoon.
Decorate top with:
- Oreo halves
- Oreo crumbs
- Swirls of whipped cream

Tips for the Perfect Oreo Crunch Texture

Best Oreos for Crunch

Regular Oreos hold firm and maintain crunch best. Avoid double-stuff in the filling.

Avoiding Soggy Oreo Filling

Add Oreo pieces right before assembling.
For extra crunch, freeze Oreo crumbs for 10 minutes before layering.

Variations of Oreo Crunch Bento Cake

Double Chocolate Version

Add mini chocolate chips into the filling.

Common Mistakes to Avoid
