This cookies and cream cake filling is straight outta the era of Tupperware parties and secret family recipes. It's a rich, thick, vanilla buttercream loaded with crushed Oreos-ready in 10 minutes and scandalously good between cake layers.
Here's why you'll want to keep this one stashed in your recipe box -

🧾 Ingredients
I recommend using butter over margarine and real vanilla extract over a vanilla flavoring. It makes a big difference in the taste of the cake filling. If you don't have heavy whipping cream, you can use a little milk in its place. However, add it slowly so you don't thin out the cookies and cream filling too much.

📖 Recipe
Oreo Cookies and Cream Cake Filling
Print Pin Recipe Rate RecipeIngredients
- 14.3 ounces Oreos
- 6 cups powdered sugar
- 1 cup butter
- 1 tablespoon vanilla extract
- ¼ cup heavy cream, may need a little more or less
Instructions
- Crumble the cookies in chunks, not too big - set aside
- Mix the confectioner's sugar and the butter until the mixture is blended and crumbly
- Add vanilla - beat well
- Add about 2 tablespoons of the cream and beat
- Beat in the cream, 2 tablespoons at a time until the mixture is creamy (you may need a bit more cream than ¼ cup)
- Stir in the crumbled cookies.
- Use to fill up to a 4-layer cake.
Notes
-
- Let the butter sit on the counter for a couple of hours to get soft-it'll make your job much easier
- Feel free to use an electric mixer to make beating easier. Opt for the paddle attachments, though-the whisk attachment is a little too fragile to handle the Oreo cookie pieces.

Novice says
How much, roughly, would I need to fill a half-sheet size cake? The cake is 12x18x3. Thank you! Double or triple the recipe?
Marye says
Great question! A half-sheet cake (12×18) holds a lot more filling than a 3-layer round cake.
As a general rule:
A standard 3-layer 8- or 9-inch cake uses filling between two layers
A half-sheet cake usually has one generous filling layer, but over a much larger surface area
To get a similar thickness of filling, you’ll want to make about double the recipe.
If you like a thicker, bakery-style filling layer, go closer to 2½ times the recipe. I wouldn’t recommend a full triple unless you’re planning an extra-thick filling or multiple layers.
Tip: make double, fill the cake, and if you want more, the recipe scales easily and comes together fast.
Holly says
I cut the powdered sugar down to about 2 1/2 cups, added a little sugar free chocolate pudding mix, then the oreos and everyone loved it.
Jayden says
about how many cupcakes will this recipe fill?

Maybe 24? I don't know for sure - I haven't used it to fill cupcakes.
Tricia says
Which type of butter do you use, salted or unsalted?
Marye says
I use salted because it's what I usually have.
