Preheat your oven to 350°F (175°C) and grease a 9-inch round cake pan. Line the bottom with parchment paper for easy removal.
In a large mixing bowl, combine the peanut butter, granulated sugar, and brown sugar. Beat with an electric mixer until well combined and smooth.
Add the eggs, one at a time, mixing well after each addition. Stir in the vanilla extract, baking powder, and salt until fully incorporated.
Pour the batter into the prepared cake pan, smoothing the top with a spatula.
Bake in the preheated oven for 28-30 minutes, or until the top is set and a toothpick inserted into the center comes out clean.
Allow the cake to cool in the pan for 10 minutes before carefully transferring it to a wire rack to cool completely.
While the cake cools, prepare the chocolate buttercream. In a medium bowl, beat the softened butter until creamy and smooth.
Gradually add the powdered sugar and cocoa powder, mixing on low speed until incorporated.
Increase the speed to medium and add the heavy cream and vanilla extract. Beat until the frosting is light, fluffy, and spreadable.
Once the cake is completely cooled, spread the chocolate buttercream evenly over the top of the cake.
Slice and serve. Store any leftovers in an airtight container at room temperature for up to 3 days.
