The Cosmic Craze: What is the Galaxy Food Trend?
The galaxy food trend has quickly emerged as the exciting successor to the rainbow food craze, transforming ordinary dishes into extraordinary celestial creations. Imagine food infused with the deep, swirling colors of space – brilliant purples, mysterious teals, deep blues, and dramatic blacks, often accented with shimmering edible glitter and sprinkles that mimic distant stars. This trend isn’t just about taste; it’s an art form that brings a sense of wonder and visual drama to your culinary endeavors. While you might still enjoy a refreshing rainbow smoothie or a colorful popsicle, the galaxy theme offers a more sophisticated and awe-inspiring aesthetic that’s perfect for celebrations or simply to elevate an everyday treat.
My Inaugural Journey into Cake Roll Creations
This particular recipe holds a special place in my heart, marking several exciting “firsts” in my baking journey. Believe it or not, this was my very first time ever making a cake roll! For years, I had admired these elegant desserts, but the thought of the cake cracking during the rolling process always made me a little hesitant. However, I’m thrilled to report that it was far simpler and more forgiving than I ever imagined, proving that even intimidating recipes can be conquered with a little courage and the right technique.
Another milestone for me was mastering the art of black chocolate ganache. Creating a truly dark, rich black ganache without compromising on flavor was a challenge I eagerly accepted, and the results were absolutely stunning. This dark, glossy coating provides the perfect contrast to the vibrant galaxy swirls within the cake, making the colors pop even more.
Furthermore, this was my first experience using Sweetapolita sprinkles – and I am now an absolute fanatic! Rosie, the brilliant mind behind Sweetapolita, is a fellow food blogger whose passion for unique sprinkle mixes led her to create her own shop. Her “Twinkle Sprinkle Medley” mix was quite literally perfect for this galaxy cake roll, adding that essential sparkle and celestial touch that truly makes the cake shine. These aren’t just sprinkles; they’re tiny bursts of edible stardust!
To achieve those mesmerizing galaxy hues, selecting the right gel food coloring is crucial. I’ve even included a picture of the exact gel food coloring brands and shades I used to ensure your cake achieves that perfect cosmic glow. Gel colors are highly concentrated, allowing you to achieve intense, deep colors without thinning your batter or frosting.
Demystifying the Cake Roll: Easier Than You Think
As I shared my exciting galaxy cake roll project with friends, I realized that many were unfamiliar with the galaxy food trend. So, I did my best to explain its captivating essence: it’s all about taking a classic recipe and infusing it with cosmic colors – think deep purples, brilliant teals, striking blues, and profound blacks, often enhanced with glittering sparkles and edible shimmer. The goal is to evoke the beauty and mystery of a distant galaxy, making every bite an ethereal experience.
For a long time, I procrastinated on making a cake roll because I harbored a misconception that it would be overly complicated, resulting in a disastrously cracked roll. However, to my pleasant surprise, the process is actually quite straightforward and incredibly rewarding! The key lies in a few simple techniques that prevent cracking and ensure a beautifully spiraled dessert.
To ensure your success, I’ve included a wealth of step-by-step photos that meticulously illustrate each stage of making this stunning cake roll. Visual guidance makes all the difference, especially for new bakers or those, like me, who might have been intimidated by this type of bake.
Crafting the Celestial Sponge: Your Step-by-Step Guide
Begin by preparing your jelly roll pan (typically 15×10 inches). Line it meticulously with parchment paper and give it a light spray with non-stick cooking spray. This crucial step ensures your delicate cake won’t stick, making the rolling process smooth and effortless. Once your vibrant batter is prepared and carefully divided into individual bowls, each tinted with its cosmic hue, it’s time for the artistry. Drizzle the various colored batters into the pan, rotating through the colors to create mesmerizing swirls and patterns reminiscent of a nebula. This artistic stage is where your galaxy truly comes to life!
Bake the cake for just 12-13 minutes. Precision is key here; overbaking can lead to a dry, crack-prone cake. The moment it’s springy to the touch, it’s ready. Immediately upon removal from the oven, invert the warm cake onto a clean kitchen towel generously dusted with powdered sugar. The powdered sugar prevents sticking and aids in the rolling process. Promptly roll the cake, along with the towel, into a tight spiral. This gentle initial roll while the cake is warm helps it “learn” its shape, preventing cracks as it cools. Place the rolled cake on a wire rack and allow it to cool completely to room temperature. Patience during this cooling phase is essential for a stable, flawless roll.
Whipped Dream Filling and the Final Roll
Once your cake has fully cooled, gently unroll it from the towel. The shape should now be set, making it easy to handle. Evenly spread the luscious filling – a delightful blend of softened cream cheese, powdered sugar, and cool whip – over the entire surface of the cake, ensuring you leave about a 1/2-inch border around the edges. This border helps prevent the filling from squeezing out when you re-roll. Carefully roll the cake back up, starting from one short end, creating a beautiful spiral. Transfer the rolled cake to a tray, placing it seam-side down, and refrigerate it to chill. The longer you allow it to chill, the firmer the filling will become, which in turn makes slicing much easier and cleaner, ensuring perfect, photo-worthy slices.
The Dark Matter Ganache: A Rich and Striking Finish
Now for the dramatic finish! Place the chilled cake roll on a wire rack, positioned over a baking sheet or parchment paper to catch any drips. Pour the velvety black chocolate ganache over the cake, allowing it to cascade down the sides. Use a spoon or a small offset spatula to gently coax the ganache and ensure any uncovered areas are neatly coated. While the ganache is still wet and pliable, generously shower your cake with the vibrant Sweetapolita sprinkles. The contrast between the dark ganache and the bright sprinkles will truly make your galaxy cake roll sparkle like a starry night sky.
I admit, I was a little nervous about achieving a truly opaque black chocolate ganache, but it turned out to be surprisingly simple and incredibly effective! The trick is to add black gel food coloring to the heavy cream as it’s heating, just before it boils. Stir it well to disperse the color evenly, then pour the hot, colored cream over your chocolate chips. Let it stand for a minute or two to allow the chocolate to melt, then stir until smooth and perfectly black. This method yields a rich, deep black color that’s perfect for a galaxy theme and can certainly come in handy for other creative baking projects, especially around Halloween!
Essential Tips for Galaxy Cake Roll Perfection
Achieving a flawless galaxy cake roll is within your reach with a few expert tips. Firstly, always ensure your eggs are at room temperature for the cake batter. This allows them to whip up to their maximum volume, creating a lighter, more pliable sponge that’s less likely to crack. When dividing and coloring your batter, use gel food colorings as they provide intense, vivid hues without adding excess liquid, which can alter the cake’s delicate texture. Mix the colors gently to avoid overworking the batter.
During the baking phase, keep a close eye on your oven. Cake rolls bake quickly, and even a minute or two too long can dry out the cake, making it brittle. The “springy to the touch” test is your best friend here. For the rolling itself, the powdered sugar on the towel is non-negotiable; it’s your insurance policy against sticking. Don’t hesitate to apply a generous layer! And remember, roll the cake immediately while it’s still hot. This is when the cake is most flexible.
For the filling, make sure your cream cheese is well softened to prevent lumps. Beat it thoroughly with the powdered sugar before gently folding in the cool whip to maintain its airy texture. The chilling time after filling is vital – it sets the filling and firms up the cake, making for clean, beautiful slices that hold their shape. Finally, when applying the ganache, ensure it’s at a pourable yet slightly thickened consistency. If it’s too hot, it will melt the cake; too cold, it will be too thick to pour smoothly. Reheat gently if needed. Don’t forget to add your sprinkles while the ganache is still wet so they adhere perfectly!

Instructions
Cake Roll
-
Preheat the oven to 350ºF. Line a jelly roll pan (15×10) with parchment paper and spray the paper with non-stick cooking spray. Set aside. In a small mixing bowl, combine the flour, baking powder and salt. Mix and set aside. In a larger mixing bowl, beat all 4 eggs on high with an electric mixer for 3 minutes. The eggs will turn pale yellow. Continuing beating the mixture as you slowly add the sugar. Add in the vegetable oil, buttermilk, apple cider vinegar, and vanilla, beat lightly. Spoon in the flour mixture, mixing until it’s just incorporated. Divide the batter among 4 bowls. Add a small amount of gel food coloring to each bowl, mixing with a spoon until the color is even. The colors we used were purple, blue, teal and black. Rotating through the colors, drizzle the batter into the pan, making swirls.
-
Bake for 12-13 minutes or until the cake is springy to the touch. Note: while baking lay a towel on a flat surface. Dust the towel with a generous amount of powered sugar. This is to prevent the cake from sticking to the towel.
-
Once the cake is done baking, immediately turn it over onto the towel. Roll the cake around the towel. Place the rolled up cake on a rack to cool completely.
Filling
-
In a medium mixing bowl, beat the cream cheese and powdered sugar until fluffy with an electric mixer, 1-2 minutes. Add in the cool whip and mix gently with a spatula.
-
Once the cake is completely cool, unroll the towel. Spread the filling over the cake roll, leaving about a 1/2 inch gap around the edges. Roll the cake roll back up and place it on a tray, seam side down, in the fridge to chill. The longer you let it chill the easier it will be to slice.
Chocolate Ganache
-
Place chocolate chips in a medium heat-proof bowl. In a small pot over low heat, heat the heavy whipping cream until just before boiling. Add in a small amount of black gel food coloring, mixing with a spatula. Pour the heavy cream over the chocolate chips. Allow the mixture to stand for 1-2 minutes. Use a spatula to stir the mixture until smooth. Allow the ganache to come to room temperature before adding it to the cake.
-
To add the ganache, place the cake roll on a rack, pour the ganache over the cake and use a spoon or spatula to cover up any areas that don’t have chocolate. Add the sprinkles. Return to the fridge to chill for 20 minutes before slicing. Slice and serve. Cover and refrigerate any leftovers.
