• Saucepan (for ganache)
• Cooling racks

Ingredients

For the Cake:

• ½ cup dark cocoa powder
• 1 cup buttermilk
• 1 ¾ cups all-purpose flour
• 2 large eggs (room temperature)
• 1 cup granulated sugar
• ½ cup vegetable oil
• 1 tsp baking powder
• 1 tsp baking soda
• ½ tsp salt
• 2 tsp vanilla extract
• 1 cup hot water

For the Peanut Butter Oreo Buttercream:

• 1 cup creamy peanut butter
• 3–4 tbsp heavy cream
• 1 lb (4 sticks) salted butter, softened
• 20 Oreo cookies, divided (crushed and whole for garnish)
• 7 cups powdered sugar
• 1 tbsp vanilla extract

For the Ganache

• 1 cup dark or semisweet chocolate (chopped or chips)
• ¾ cup heavy cream

Instructions

Step 1: Prepare Cake Batter

Preheat oven to 350°F (175°C). Grease and flour two 9-inch round cake pans. In a large bowl, sift together the cocoa powder, flour, baking powder, baking soda, and salt.

Step 2: Combine Wet Ingredients

In another bowl, whisk together eggs, granulated sugar, vegetable oil, buttermilk, and vanilla extract until well combined.

Step 3: Mix Dry and Wet Ingredients

Gradually add the dry ingredients to the wet mixture, alternating with the hot water. Mix until smooth but do not over mix.

Step 4: Bake the Cake

Divide the batter evenly between the prepared pans. Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean. Let cakes cool in pans for 10 minutes, then transfer to wire racks to cool completely.

Step 5: Prepare Peanut Butter Oreo Buttercream

In a large bowl, beat the softened butter until creamy. Add the peanut butter and vanilla extract; beat until combined. Gradually add powdered sugar, one cup at a time, beating well after each addition. Add heavy cream to reach desired consistency.

Step 6: Add Oreos to Buttercream

Crush 15 Oreos roughly and fold them gently into the peanut butter buttercream.

Step 7: Make Ganache

Heat heavy cream in a saucepan over medium heat until just simmering. Pour over chopped chocolate in a heatproof bowl. Let sit for 2 minutes, then stir until smooth. Allow to cool to room temperature.

Step 8: Assemble the Cake

Place one cake layer on a serving plate. Spread a thick layer of peanut butter Oreo buttercream on top. Place the second cake layer over it. Cover the entire cake with the remaining buttercream.

Step 9: Decorate and Finish

Pour the ganache over the top of the cake, letting it drip down the sides. Decorate with the remaining whole Oreos. Chill the cake for at least 30 minutes before serving.

Special Notes

For an extra peanut butter punch, you can fold chopped peanut butter cups into the frosting or batter. If you don’t have buttermilk, make a quick substitute by adding 1 tbsp lemon juice or vinegar to 1 cup of milk and let it sit for 5 minutes.

Always ensure the cake layers are completely cool before frosting to avoid melting your frosting. Feel free to use crunchy peanut butter if you want added texture in the frosting.

Tips And Tricks For Perfect Peanut Butter Oreo Cake

1. Always use eggs and butter at room temperature. This helps the ingredients blend smoothly, creating a light and fluffy cake and creamy frosting.

2. Sift the cocoa powder, flour, baking soda, and baking powder together to remove lumps and ensure the dry ingredients are evenly mixed, giving the cake a tender crumb.

3. Slightly warm the buttermilk before mixing it in. Warm buttermilk helps dissolve the cocoa powder better, resulting in a richer chocolate flavor and smoother batter.

4. When folding crushed Oreos into the buttercream, do it gently to keep some pieces intact for a satisfying crunch in every bite.

5. Make sure the cake layers are completely cool before frosting. Frosting a warm cake can cause it to melt or become runny, affecting the texture and appearance.

6. After assembling and frosting, chill the cake in the refrigerator for at least 30 minutes. This helps the buttercream firm up and makes slicing cleaner and easier.

7. Use good quality creamy peanut butter and real chocolate for the ganache. Better ingredients make a noticeable difference in the cake’s overall taste and texture.

Serving And Decorate Ideas

To serve, cut the Peanut Butter Oreo Cake into even slices and pair it with a small spoonful of peanut butter sauce or caramel drizzle for extra richness.

For decoration, press halved Oreos around the sides of the cake or sprinkle finely crushed Oreos over the frosting for a crunchy finish. Adding a light dusting of cocoa powder or chopped roasted peanuts on top brings a nice contrast.

You can also add small clusters of chopped chocolate or a few peanut butter cups for a fun and tasty garnish that makes the cake look inviting and delicious.

When To Serve

Peanut Butter Oreo Cake is great to serve during celebrations like birthdays, holidays, or special family gatherings.

It’s also a wonderful treat for weekend dessert or anytime you want to impress guests with something rich and flavorful. This cake works well after a nice meal or paired with afternoon coffee or tea.

Serving it slightly chilled makes the frosting and ganache set beautifully, creating a perfect texture and taste for any occasion.

Additions and Variations

Additions:

• Chopped peanuts — sprinkle inside the frosting or on top for extra crunch.
• Mini chocolate chips — fold into the batter or buttercream for bursts of chocolate.

How To Store The Finished Peanut Butter Oreo Cake
