Ingredients
Scale
Cake Batter
- 4 large eggs (room temperature)
- 3/4 cup granulated sugar
- 1 teaspoon vanilla extract
- 1/4 cup whole milk
- 1/4 cup vegetable oil
- 1 cup all-purpose flour
- 1 teaspoon baking powder
- 1/4 teaspoon salt
- Gel food coloring in blue, purple, pink, and black
- Powdered sugar for dusting
Whipped Cream Filling
- 1 cup heavy whipping cream
- 2 tablespoons powdered sugar
- 1/2 teaspoon vanilla extract
Decoration (Optional)
- Edible glitter or star-shaped sprinkles
Instructions
- Prepare the Cake Batter: Preheat your oven to 350°F (175°C) and line a 10×15-inch jelly roll pan with parchment paper. In a large bowl, beat the eggs with an electric mixer on high speed for 4–5 minutes until the mixture becomes thick and pale. Gradually add the granulated sugar and vanilla extract, continuing to beat until fully incorporated. In a separate small bowl, whisk together the milk and vegetable oil, then fold this mixture into the eggs. Sift in the flour, baking powder, and salt, gently folding everything together until just combined.
- Create Galaxy Pattern: Divide the batter evenly into four separate bowls. Tint each bowl with a different gel food coloring: blue, purple, pink, and black. Spoon drops of each colored batter randomly into the prepared baking pan. Using a skewer or knife, gently swirl the colors together to create a galaxy pattern, being careful not to overmix and blend the colors too much. Smooth the top of the batter and tap the pan gently to release any air bubbles.
- Bake the Cake: Bake the batter in the preheated oven for 12–14 minutes, or until the cake springs back when lightly touched. While the cake bakes, lay out a clean kitchen towel and dust it generously with powdered sugar.
- Roll the Cake: Immediately after removing the cake from the oven, turn it out onto the prepared towel. Carefully peel off the parchment paper. Roll the cake up gently in the towel from the short side to prevent cracking. Let the cake roll cool completely while wrapped.
- Prepare the Whipped Cream Filling: In a chilled mixing bowl, whip the heavy cream, powdered sugar, and vanilla extract together until stiff peaks form. Take care not to overwhip.
- Assemble the Cake Roll: Once the cake has cooled, gently unroll it. Spread the whipped cream filling evenly over the surface, then carefully re-roll the cake without the towel.
- Chill and Decorate: Chill the assembled cake roll in the refrigerator for at least 1 hour to set. Before serving, decorate the outside with edible glitter or star-shaped sprinkles to enhance the galaxy effect.
Notes
- Use gel food coloring to achieve the brightest and most vibrant galaxy colors.
- Avoid overmixing the batter when folding in flour and when swirling colors, to maintain distinct and vivid swirls.
- Chill the cake roll before slicing to achieve cleaner, neater slices.
- For a tangier option, substitute the whipped cream filling with a cream cheese-based filling.
