  • 1/2 tsp Baking soda
  • 1 tsp Salt
  • 1 cup Oil (canola or vegetable)
  • 1 3/4 cup White granulated sugar
  • 1 tsp Pure vanilla extract
  • 4 Large eggs (room temperature)
  • 1 cup Buttermilk (room temperature)
  • 1 cup Hot water

Oreo Peanut Butter Pie Filling

  • 4 oz Cream cheese (room temperature)
  • 1/3 cup Peanut butter (creamy Jif or Skippy)
  • 1 TBSP Heavy cream
  • 1 cup Heavy cream
  • 1/3 cup Powdered sugar
  • 1 tsp Pure vanilla extract
  • 8 Oreos

Oreo Peanut Butter Buttercream

  • 2 cups Unsalted butter (room temperature)
  • 1 cup Peanut butter (creamy Jif or Skippy)
  • 3 cups Powdered sugar (sifted)
  • 1 tsp Pure vanilla extract
  • 5 Oreos
  • Extra Oreos for decoration

Instructions

  1. Preheat and Prepare Pans: Preheat the oven to 350℉. Spray three 8-inch cake pans with baking nonstick spray. Line the bottoms with parchment paper circles and spray again to ensure easy cake release.
  2. Sift Dry Ingredients: In a medium bowl, sift together the flour, cornstarch, baking powder, baking soda, and salt. Set aside.
  3. Mix Wet Ingredients: Start heating hot water on the stove. In a large bowl, whisk together the oil, sugar, vanilla, eggs, and buttermilk until well combined. Slowly whisk in the hot water to the mixture.
  4. Combine Batter: Add the dry ingredients to the wet ingredients and whisk until you achieve a smooth batter. Divide the batter evenly between the three prepared cake pans.
  5. Bake Cake Layers: Bake the cakes for 24-29 minutes, or until a toothpick inserted into the center comes out clean. Let the cakes sit in the pans for 10 minutes before transferring to a cooling rack. Cool completely.
  6. Prepare Oreo Peanut Butter Pie Filling: In a small bowl, beat the cream cheese, peanut butter, and 1 tablespoon heavy cream with a hand mixer on high speed until smooth. In a separate large bowl with a mixer and whisk attachment, beat the 1 cup heavy cream, powdered sugar, and vanilla on high speed until soft peaks form. Add the peanut butter and cream cheese mixture and beat until stiff peaks form.
  7. Add Oreos to Filling: Using a food processor, pulse the 8 Oreos into small and medium pieces. Fold the crushed Oreos into the peanut butter filling. Set aside.
  8. Prepare Oreo Peanut Butter Buttercream: Sift the powdered sugar in a bowl. Process the 5 Oreos into fine crumbs in a food processor. Using a mixer, beat the butter on high for 2 minutes until creamy. Add peanut butter and beat another minute until smooth.
  9. Incorporate Sugar and Flavor: Add half of the powdered sugar to the butter mixture and mix on low until just combined. Add the remaining powdered sugar and mix. Scrape the bowl, add vanilla extract and beat on high speed for 1 minute until creamy. Fold in the Oreo crumbs.
  10. Assemble the Cake: Slice off the domes from the cake layers with a serrated knife. Place the first layer on a serving plate and spread 1 cup of filling evenly over the top. Repeat with the second layer and filling, then place the third cake layer upside down (bottom side up) on top.
  11. Frost and Decorate: Apply a thin crumb coat of the frosting over the assembled cake and place it in the freezer for 15 minutes to set. Finish frosting the cake with the remaining buttercream. Decorate the top with extra Oreos as desired.

Notes

  • Room temperature eggs, cream cheese, and buttermilk help create a smooth batter and filling.
  • Make sure to evenly distribute batter between pans to ensure uniform cake layers.
  • Using dutch-processed cocoa contributes to a richer chocolate flavor.
  • The cake can be stored covered in the refrigerator up to 3 days or frozen for longer storage.
  • Allow frosting to reach room temperature before spreading if refrigerated.
  • For cleaner cake layers, refrigerate the frosted cake briefly to set the frosting before piping decorations.
