Ingredients
Scale
Cake
- 4 large eggs
- 3/4 cup granulated sugar
- 1 teaspoon vanilla extract
- 3/4 cup all-purpose flour
- 1 teaspoon baking powder
- 1/4 teaspoon salt
- Gel food coloring (purple, blue, black, pink)
- 1/4 cup whole milk
- 2 tablespoons vegetable oil
Filling
- 1 cup heavy whipping cream
- 1/4 cup powdered sugar
- 1 teaspoon vanilla extract
Galaxy Effect
- Edible glitter or luster dust
- Star sprinkles (optional)
Instructions
- Prepare the pan and oven: Preheat your oven to 350°F and line a 10×15-inch jelly roll pan with parchment paper for easy cake removal.
- Make the batter base: In a large bowl, beat the eggs, granulated sugar, and vanilla extract with a hand mixer until the mixture is light and fluffy, approximately 5 minutes.
- Combine dry ingredients: In a separate bowl, whisk together the flour, baking powder, and salt to evenly distribute the leavening agents.
- Incorporate dry ingredients: Gradually fold the flour mixture into the egg mixture gently to avoid deflating the batter.
- Add liquids: Mix the milk and vegetable oil together, then fold this mixture gently into the batter for moisture and tenderness.
- Color the batter: Divide the batter evenly into four small bowls and tint each with a different gel food coloring: purple, blue, black, and pink.
- Create galaxy pattern: Spoon dollops of each colored batter randomly into the prepared pan. Using a skewer, swirl the colors lightly to form a marbled galaxy effect.
- Bake the cake: Bake for 10 to 12 minutes or until the cake springs back to the touch, indicating it is fully baked.
- Cool and roll: Immediately invert the cake onto a clean kitchen towel dusted with powdered sugar, peel off the parchment, and roll the cake up with the towel from the short side. Let it cool completely rolled up.
- Prepare the filling: Beat the heavy whipping cream, powdered sugar, and vanilla extract in a bowl until stiff peaks form, ensuring a stable whipped cream.
- Assemble the cake: Once the cake is cooled, carefully unroll it, spread the whipped cream evenly over the surface, then re-roll the cake snugly.
- Decorate and serve: Dust the outside with edible glitter and add star sprinkles if desired for a magical finishing touch before slicing and serving.
Notes
- Use gel food coloring instead of liquid for more vibrant and deeper colors in the cake batter.
- Store the finished cake roll in the refrigerator until ready to serve to keep the filling firm.
- You can freeze the cake roll without decorations for up to 1 month. Thaw in the fridge before adding edible glitter and sprinkles.
