Preheat the oven to 350°F (175°C). Grease and flour two 9-inch round cake pans or line them with parchment paper.
In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, unsweetened cocoa powder, baking powder, baking soda, and salt.
Add the eggs, sour cream, vegetable oil, and vanilla extract to the dry ingredients. Mix until just combined.
Pour in the boiling water slowly, mixing until the batter is smooth. The batter will be thin, which is normal.
Divide the batter evenly between the prepared cake pans.
Bake in the preheated oven for 28-32 minutes, or until a toothpick inserted into the center comes out clean.
Remove the cakes from the oven and let them cool in the pans for 10 minutes. Then invert them onto a wire rack to cool completely.
To make the frosting, beat the unsalted butter and creamy peanut butter together in a large mixing bowl until smooth and creamy.
Add the powdered sugar and unsweetened cocoa powder, mixing on low speed to combine.
Gradually add the milk and vanilla extract, beating until the frosting is smooth and spreadable. Add more milk if needed to reach the desired consistency.
Once the cakes are completely cool, place one layer on a serving plate. Spread an even layer of frosting on top.
Place the second cake layer on top and frost the top and sides of the cake evenly.
Serve immediately or store in an airtight container at room temperature for up to 2 days.
