Step-by-Step Instructions for Making Oreo Chocolate Cake

1. Bake the Moist Chocolate Cake Layers

1. Preheat oven to 350°F (175°C). Grease and line two 9-inch cake pans.
2. In a large bowl, whisk together flour, cocoa powder, granulated sugar, brown sugar, baking powder, and baking soda.
3. In another bowl, whisk together buttermilk, oil, eggs, and vanilla extract.
4. Gradually stir the wet ingredients into the dry until just combined.
5. Carefully pour in the hot water, stirring slowly, the batter will be thin (that’s what makes it moist!).
6. Divide the batter evenly between pans and bake for 35–40 minutes.
7. Let the cakes cool in the pans for 20 minutes before transferring to wire racks.
8. Once fully cooled, wrap each cake in plastic wrap and refrigerate for 2+ hours for easy frosting.

Tip: Cold cakes are easier to frost and less likely to crumble. Don’t skip this step!

2. Whip Up the Oreo Buttercream Frosting

1. Use a food processor (or rolling pin and bag) to crush Oreos into fine crumbs.
2. Beat softened butter in a mixer for 2 minutes until pale and fluffy.
3. Add Oreo crumbs and vanilla extract, mixing until fully incorporated.
4. Gradually add powdered sugar and heavy cream, beating until smooth and airy (about 4–5 minutes).

This cookies-and-cream frosting is so good, you’ll want to eat it by the spoonful. It’s the heart of this Oreo chocolate cake and brings that iconic flavor to every bite.

3. Assemble and Frost the Cake

1. Remove chilled cake layers and trim any domes for even stacking.
2. Add a small dollop of frosting on your cake board to anchor the first layer.
3. Spread about 1 cup of Oreo buttercream on the first layer.
4. Add the second cake layer and apply a thin crumb coat. Chill for 10 minutes.
5. Frost the cake fully, smoothing the sides and top for a polished look.
6. Chill again for at least 10 minutes to firm up the frosting.

4. Drizzle with Chocolate

1. In a microwave-safe bowl, melt chocolate chips and coconut oil in 20-second bursts, stirring until smooth.
2. Let cool slightly (about 2–3 minutes), then pour over the center of the cake, letting it drip down naturally.
3. Chill for 10 minutes to set the drizzle.

5. Garnish Like a Pro

1. Pipe whipped cream rosettes around the top edge of the cake.
2. Top each rosette with a whole Oreo for an eye-catching finish.
3. Let the cake sit at room temperature for 1 hour before serving to soften and enhance the texture.
