Ingredients

Chocolate Cake

2 Eggs Large, Room temperature
1 cup Oil
1 tablespoon Vanilla extract
1 cup Buttermilk
1 cup Water Warm
2 cups All-purpose flour
2 cups Granulated sugar
¾ cup Cocoa powder
¼ tsp Baking powder
1 ½ teaspoon Baking soda
1 cup Chocolate ganache
15 Oreos Roughly chopped, For decoration
½ cup Mini chocolate chips For decoration

Oreo Buttercream Frosting

¾ cup Butter Unsalted, Room temperature
¾ cup Shortening
4-5 cups Powdered sugar
1 ½ cups Oreo crumbs
1 teaspoon Vanilla extract
3-4 tablespoon Milk or Heavy cream

Instructions

Cake

In a mixing bowl, add eggs, oil, vanilla extract, buttermilk, water and mix everything until fluffy.
In a separate bowl, whisk together the flour, sugar, cocoa powder, baking powder and baking soda.
Dump this dry mixture into the wet mixture and mix until just combined. Do not over-mix!
Pour batter into 2 greased and floured round cake pans (Dimensions: 8x2).
Bake at 325 degrees F for about 40 minutes or until an inserted toothpick comes out clean.
Let the cakes cool down completely.

Frosting

In a mixing bowl, cream together butter and shortening.
Add vanilla extract and mix again.
Add powdered sugar slowly and continue mixing.
Add Oreo crumbs slowly and continue mixing.
Add milk or heavy cream (1 tablespoon at a time) until frosting is smooth and creamy.

Ganache

In a microwave- safe bowl, melt chocolate in 30 second increments.
Add heavy cream and mix until smooth.

Assembling

Once the cakes have fully cooled down, cut the domes and make them flat.
Place one cake on a cake stand and top it off with Oreo frosting.
Place the other cake on top of the frosting and gently press it down .
Cover the entire cake with frosting, if you like (Optional).
Pour ganache on top of the cake and use a spatula to spread it out until it starts dripping along the sides.
Toss mini chocolate chips along the base of the cake.
Prior to serving, pipe some frosting on top of the ganache and decorate the cake with chopped Oreos and enjoy!

Notes

You can mix in 6-7 roughly chopped Oreos in the cake batter too, if you like. I didn't do it because I find it harder to cut slices that way.
Don't assemble a warm cake because the heat will cause the icing to melt.
Please line your pans with parchment paper or grease and flour them to prevent them from sticking to the pan.
Do not over mix cake batter because that makes the texture very gummy. Mix until just combined. A few lumps are normal.
Read additional tips and variations above.
Leftovers can be stored in a sealed container in the fridge for up to 3 days.
