PREPARATION STEPS

Prepare the Chocolate Cake:
Preheat the oven to 350°F (177°C). Grease and line three 8-inch round cake pans.
In a large bowl, whisk together the flour, cocoa powder, sugar, baking soda, baking powder, and salt.
Add the eggs, oil, sour cream, buttermilk, and vanilla extract. Mix until combined.
Gradually add the hot water or coffee, mixing until the batter is smooth.
Divide the batter evenly among the prepared pans.
Bake for 25 minutes, or until a toothpick inserted into the center comes out clean.
Allow the cakes to cool in the pans for 10 minutes, then transfer to wire racks to cool completely.
Prepare the Peanut Butter Frosting:
In a large bowl, beat the butter and peanut butter together until creamy.
Add the confectioners’ sugar, vanilla extract, and salt. Beat until combined.
Add the heavy cream and beat on high speed until the frosting is light and fluffy.
Assemble the Cake:
Place one cake layer on a serving plate. Spread a layer of peanut butter frosting on top.
Sprinkle chopped mini peanut butter cups over the frosting.
Repeat with the second layer.
Place the third layer on top and apply a thin crumb coat of frosting over the entire cake.
Refrigerate the cake for 30 minutes to set the crumb coat.
Prepare the Chocolate Ganache:
Place the chopped chocolate in a heatproof bowl.
Heat the heavy cream until it just begins to simmer.
Pour the hot cream over the chocolate and let it sit for 2-3 minutes.
Stir until the ganache is smooth and glossy.
Allow the ganache to cool slightly before using.
Decorate the Cake:
Divide the remaining peanut butter frosting into separate bowls and tint each with different food coloring gels to create galaxy colors.
Apply dollops of each colored frosting onto the cake and use a spatula to swirl them together, creating a galaxy effect.
Pour the slightly cooled ganache over the top of the cake, allowing it to drip down the sides.
Sprinkle edible glitter or stars over the ganache.
Decorate the top with additional mini peanut butter cups.
