Oreo Red Velvet Cake

A few weeks ago, I made a a very special cake for a good friend’s birthday!! She loves red velvet cake and Oreos, which were in the inspiration for this cake.

I also threw some sprinkles into the mix, for good measure 😛

I tried to incorporate all of there favorite things, which included red velvet cake, funfetti sprinkles, and tons of Oreos!!

Red Velvet Oreo Cake:

  • 3 cups flour
  • 1/4 cup of unsweetened cacao
  • 3 cups granulated sugar
  • 2 1/2 tsp baking powder
  • 1 tsp salt
  • 1 cup unsalted butter (2 sticks), room temperature
  • 3 tsp. vanilla extract
  • 1 cup egg whites (about 7 large egg whites)
  • 1 1/2 cups buttermilk, room temperature
  • 1/8 cup vegetable oil
  • red gel food coloring
  • 1 1/2 cups crushed Oreos

Vanilla Frosting:

  • 6 sticks (3 cups) unsalted butter, room temperature
  • 12 cups powdered sugar
  • 1/2 tsp salt
  • 3 Tbsp. heavy cream
  • 3 tsp vanilla

Chocolate Ganache Drips:

  • 1/2 cup heavy cream (about 4 oz.)
  • 1/2 cups chocolate chips (9 oz.)
  • plastic squirt bottle

Additional Decorations:

  • 1 cup crushed oreos
  • 1 cup rainbow sprinkles

Red Velvet Cake Layers

Preheat oven to 350°F. Grease and line four 8” round pans.

Mix together all dry ingredients (flour, cacao, baking powder, sugar, and salt) in a stand mixer with a paddle until fully combined.

Mix chunks of room-temperature butter slowly into the dry mix, on a low speed.

Continue to mix until no large chunks of butter remain, and the mixture becomes crumbly.

Pour in egg whites, and mix on low until just incorporated.  

Mix in the buttermilk in two installments, on a low speed.

Add in vanilla, gel food coloring, and oil, and mix at a low speed until fully incorporated.

Scrape down the sides of the bowl with a spatula, then beat on medium high for about 30 seconds.

Gently fold in crushed Oreos.

Divide evenly between prepared cake pans. 

Bake for 32-35 minutes, or until a skewer comes out clean. 

Allow to cool for 10 minutes, then run an offset spatula around perimeter of the pan to separate the cake from the pan.

Place cake layers on a rack to finish cooling.

Vanilla Buttercream Frosting

While the cake layers bake and cool, prepare the vanilla buttercream frosting.

Beat the butter on high for 30 seconds with a paddle attachment, until smooth.

Slowly add in the powdered sugar, 1 cup at a time. Alternate with small splashes of cream.

Once fully mixed, add in the vanilla and salt, and beat on medium low until the ingredients are fully incorporated, and the desired consistency is reached.

If the frosting is too thick, add in cream (1 teaspoon at a time).

If the frosting is too thin, add in more powdered sugar (quarter of a cup at a time).

NOTE: When making frosting for a cake, it is important to mix the buttercream on low at the end of the process for a couple minutes, to get out any extra air that might have be incorporated during the mixing process.

This will make it easier to get super smooth sides on your cake!

Chocolate Ganache

Once the frosting is prepare, make the chocolate ganache drip recipe.

Heat heavy cream in a heat-proof bowl in the microwave for 45 seconds-1 minute, until bubbling.

Gently pour chocolate chips into the heavy cream, making sure they are fully covered with cream.

Allow mixture to sit for 2 minutes.

Stir slowly until the cream and white chocolate are combined, then heat again for 20 seconds and stir.

Repeat as necessary until all the chocolate bits are fully melted and incorporated.

If it seems too thin or thick, you can add a touch more chocolate chips or heavy cream!

The type of cream and chocolate that you use can affect the consistency, so feel free to adjust as needed.

Pour into plastic squirt bottles.

I like to put my ganache into plastic squirt bottles when decorating cakes! But you can also use a spoon to drizzle it over cakes. Extra ganache can be kept in the fridge for 2 weeks.

Cake Assembly

Once the cake layers are fully cooled, assemble the cake.

Stack and frost layers with buttercream. 

Apply a thin crumb coat, and chill the cake in freezer for 5 minutes.

Once the crumb coat is firm to the touch, apply, a second, thicker coat of frosting.

Smooth with a bench scrapper.

If you want to see a full tutorial for how I get smooth sides on my cakes, you can click here.

Gently press crushed Oreos and sprinkles onto the sides of the cake.

Smooth into frosting using an acetate sheet.

Place cake in freezer for 15 minutes.

Once the cake is fully chilled, use a squirt bottle to add the ganache drips.

I also added some birthday cake Oreos around the base of the cake, and piped some swirls onto the top using a Wilton 1M tip.

how much cake icing do you usually make when baking normal 2 or 3 layer cake, do you make 2 icing recipes?

Hi Debbie,

I usually make about 1 1/2 batches of my american buttercream recipe, which is what's reflected on this recipe cake. That ensures I have enough frosting for big swirls on top of the cake. If you're making a 2 layer cake with 8 inch cake layers, you can probably make a single batch of frosting. Hope that helps, happy baking!
