Cake Roll:
  • 1 cup all-purpose flour
  • 1 tsp baking powder
  • 1/2 tsp salt
  • 4 large eggs, room temperature
  • 3/4 cup granulated sugar
  • 2 tbsp vegetable oil
  • 2 tbsp buttermilk
  • 1 tsp apple cider vinegar
  • 1 tsp vanilla extract
  • Gel food coloring: black, purple, teal, and blue
  • 4 oz cream cheese, softened
  • 1 cup powdered sugar
  • 2 cups cool whip
Chocolate Ganache:
  • 1/2 cup heavy whipping cream
  • 1 cup semi-sweet chocolate chips
  • Black gel food coloring


  1. Prepare the Cake:
    • Preheat the oven to 350°F (175°C). Line a 15×10-inch jelly roll pan with parchment paper and lightly spray with non-stick cooking spray.
    • In a small bowl, combine flour, baking powder, and salt. Set aside.
    • In a large bowl, beat eggs on high speed for 3 minutes until they turn pale yellow. Gradually add sugar, followed by vegetable oil, buttermilk, vinegar, and vanilla.
    • Gently fold in the flour mixture until just incorporated.
    • Divide the batter among four bowls and tint each with different gel food colorings. Drizzle the colored batter into the prepared pan to create a galaxy effect.
    • Bake for 12-13 minutes, or until the cake springs back when touched lightly.
  2. Roll the Cake:
    • Lay a clean towel on a flat surface and dust generously with powdered sugar. Immediately after removing the cake from the oven, invert it onto the towel, remove the parchment paper, and roll the cake along with the towel. Allow it to cool completely.
  3. Make the Filling:
    • Beat cream cheese with powdered sugar until fluffy. Gently fold in the cool whip.
  4. Fill the Cake:
    • Carefully unroll the cooled cake, spread the filling evenly across the surface, leaving a small margin at the edges. Roll the cake back up without the towel and place it seam side down to chill.
  5. Prepare the Ganache:
    • Heat the cream until it just begins to boil, then pour over the chocolate chips and a bit of black food coloring. Let sit for a few minutes, then stir until smooth. Allow the ganache to cool to room temperature.
  6. Finish the Cake:
    • Place the chilled cake roll on a rack over a sheet pan. Pour the ganache over the cake, ensuring it is fully covered. Decorate with festive sprinkles.
    • Chill the cake in the refrigerator for about 20 minutes before slicing.


  • Avoid Overbaking: To prevent the cake from cracking during rolling, it’s crucial not to overbake it.
  • Powdered Sugar Towel: Dusting the towel with powdered sugar helps to prevent the cake from sticking without adding too much sweetness.
  • Chill Before Ganache: Ensure the filled cake is thoroughly chilled before applying the ganache to maintain the cake’s structure.


This Galaxy Cake Roll not only dazzles with its appearance but also delights with its flavors. Whether you’re hosting a space-themed party, celebrating a special occasion, or just want to try something new and exciting, this cake is sure to impress.
