Equipment

  • Large mixing bowl
  • Electric mixer
  • Spatula
  • Three 8-inch round cake pans
  • Offset knife for frosting

Ingredients

  • 2 1/4 cups all-purpose flour
  • 1 1/2 cups granulated sugar
  • 2 teaspoons baking powder
  • 1 teaspoon salt
  • 1/2 cup unsweetened cocoa powder
  • 1 cup whole milk at room temperature
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1 1/2 cups creamy peanut butter
  • 3 1/2 cups powdered sugar
  • 2 tablespoons unsalted butter softened
  • 2 teaspoons vanilla extract
  • 1 cup semisweet chocolate chips
  • 1/2 cup heavy cream
  • 1/4 cup blue and purple gel or paste food coloring
  • 1/4 cup white chocolate chips or chopped white chocolate

Instructions

  • Preheat your oven to 350°F (180°C) and grease and flour three 8-inch round cake pans.
  • In a large bowl, whisk together the dry ingredients: flour, sugar, baking powder, salt, and cocoa powder.
  • In another bowl, mix the wet ingredients: milk, eggs, and vanilla, and then combine them gently with the dry ingredients until the batter is smooth.
  • Divide the batter evenly among the prepared pans.
  • While the cakes cool, make the peanut butter buttercream by creaming peanut butter and softened butter until light and fluffy.
  • Gradually add powdered sugar, mixing on low speed, and finish with vanilla extract.
  • To create the chocolate ganache, melt chocolate chips and heavy cream in a heatproof bowl over simmering water and stir until smooth.
  • Place one cake layer on a serving plate and spread peanut butter buttercream on top. Repeat with remaining layers.
  • Apply a thin crumb coat of frosting over the entire cake and chill for 15 minutes.
  • Cover the cake with the remaining buttercream.
  • Melt white chocolate and drizzle it over the frosted cake, swirling with a toothpick to create a marbled effect with blue and purple food coloring.

Notes

For a gluten-free version, swap all-purpose flour with gluten-free flour. Use almond milk for a dairy-free option and consider sunflower seed butter as a nut-free alternative. Enhance the galaxy effect with edible glitter for a twinkling star look! Store leftovers in an airtight container at room temperature for up to 2 days or refrigerate for a week. For longer storage, freeze individual slices for up to 3 months.
