If you’ve ever wanted to make a homemade cake that feels impressive but doesn’t require a culinary degree… this is it.
This Oreo cake is rich, chocolatey, a little messy in the best way—and topped with the kind of Oreo buttercream that makes people go quiet after the first bite. (You know the kind.)
And the best part? It’s forgiving. Like, “sploosh of vanilla” forgiving.

Ingredients
Chocolate Cake
- 2 cups flour
- 2 cups sugar
- ¾ cup unsweetened cocoa powder
- 2 tsp baking soda
- 1 tsp salt
- 2 eggs
- 1 cup milk
- 1 cup melted butter
- 1 sploosh vanilla (about 1–2 tsp)
- 1 cup boiling water
Oreo Buttercream + Filling
- 2 ½ sticks butter (room temp)
- 4 cups powdered sugar
- 1 ½ cups Oreo crumbs
- 1 sploosh vanilla
- 5 tbsp heavy whipping cream
- Pinch of salt
- 5–10 Oreos, chopped
How to Make It
Step 1: Make the Cake Batter
Preheat your oven to 300°F (yes, 300—trust the process).
In a large bowl, mix together:
- flour
- sugar
- cocoa powder
- baking soda
- salt
Add in:
- eggs
- milk
- melted butter
- vanilla
Mix until smooth.
Now carefully stir in the boiling water.
(It will look thin—this is exactly what you want.)
Step 2: Bake
Pour the batter into greased cake pans.
Bake for about 30 minutes, or until a toothpick comes out slightly crumby (not wet, not dry).
Let the cakes cool completely before frosting—unless you enjoy melted frosting sliding off your cake (no judgment).
Step 3: Make the Oreo Buttercream
In a large bowl:
- Beat the butter until smooth
- Slowly add powdered sugar
- Mix in Oreo crumbs
- Add vanilla and salt
- Pour in heavy cream and whip until fluffy
Fold in the chopped Oreos last for texture.
Step 4: Assemble the Cake
- Place one cake layer down
- Spread a thick layer of Oreo buttercream
- Add the second layer
- Frost the top and sides
Don’t worry about making it perfect—this is a “rustic Oreo masterpiece” situation.
Tips (From Someone Who’s Made the Mess Already)
- If your frosting feels too thick → add a splash more cream
- Too thin → more powdered sugar
- No fancy tools? A butter knife works just fine
- Kids hovering in the kitchen? Give them a spoon and accept your fate
