I made these black velvet cupcakes simply by using black food coloring instead of red food coloring with my red velvet cake recipe. If you want you can take a little help from a box mix, simply follow my Awesome Cake from a Cake Mix using a red velvet cake mix and add the black food coloring to it.
After baking and time to cool, I filled the cupcakes using a filling tip and a piping bag filled with chocolate ganache.
Supplies to make the galaxy frosting:
black gel food coloring
pink gel food coloring
purple gel food coloring
teal gel food coloring
large round piping tip
white pearl sprinkles
white glitter crystal sprinkles
silver glitter dust
To create the galaxy effect with the icing, I started by whipping up a batch of my buttercream frosting. Then I dirtied up a bunch of bowls (all for a good cause…cake!!) by tinting my buttercream black, teal, pink, and purple. I like to use gel coloring, not the liquid coloring found on the spice aisle in the grocery store. Although those have gotten better as far as color variety, I find that it’s really hard to achieve deep rich colors. For the white frosting, I just left it alone.
Tip: For the black frosting, I add a tablespoon or two of cocoa powder to the buttercream first. This combats the bitter taste that black icing can have and also allows you to use less black food coloring.
Now to get the lovely swirl effect, you first lay out a piece of plastic wrap. Then spoon lines of the different color icing onto the plastic wrap.
Next, carefully roll the plastic wrap up and twist the ends to get rid of air.
Prep a piping bag or sandwich bag for the icing by snipping the end. Now carefully slide your plastic wrap tube of icing through a coupler then slide both into the piping bag and down to the snipped end. Make sure to pull the plastic all the way through the coupler and piping bag until the icing reaches the end. Then snip the excess plastic wrap add the tip and ring and you are ready to add some colorful swirl galaxy to your cupcakes.
This method is also good for rainbow swirls with any colors you want to use and for making flowers with multiple colors.
Before piping on the cupcake, squeeze out a little icing on a plate or one of the icing bowls, just to test that the color swirl is happening. Sometimes just one color comes out for a bit before the swirl starts.
Assemble the Black Velvet Cupcakes with Galaxy Frosting
To pipe the galaxy swirl onto the cupcake, start on the outside edge of the cupcake, holding the piping bag at a 90-degree angle just slightly above the cupcake. Then while applying medium pressure circle around the cupcake moving towards the middle. Once the middle is reached, release the pressure and pull up on the bag. If too big of a little kiss sticks up and you don’t like it, just dip a clean finger or small paint brush in a bit of water and smooth down. You can turn the piping bag in your hand a little before piping each cupcake to get more variation. I just love how each cupcake is a little different.
To create the stars and shimmer of the galaxy, I used small pearl sprinkles, white glitter crystal sprinkles, and silver glitter dust. I placed just 3-5 pearls on each cupcake and then scattered the glitter crystals over that. Finally, I added a sprinkling of the silver glitter dust just to give them a little all over sparkle.
These black velvet cupcakes with galaxy frosting are an out of this world treat you’ll want to try. What are you waiting for? Go get you cake on!
