Star Wars Inspired Galaxy Cake with Mirror Glaze

Thank you for sharing!

Ever since the Americas Cake Fair,  I have had the cake decorating bug. Since I have a very talented friend, Sherri, I asked her if she would teach me some cake decorating. She said yes! I was so excited to decorate a cake with more flair than just throwing on some frosting and sprinkles. The first cake I wanted to tackle was a Star Wars Inspired Galaxy Cake to celebrate the Star Wars: The Last Jedi movie. This cake was fun to make and turned out (in my not so humble opinion) to be so pretty!

For the cake recipe, I made Buddy Valastro’s vanilla cake. I made 2 round layers with that mix. Once  I brought the cakes over to Sherri’s she suggested I add more layers to make it taller. At that point, we just used a boxed cake mix.

Buttercream Icing Recipe

I am not a huge fan of buttercream icing, I prefer cream cheese icing but I learned that cream cheese icing is too soft for cake decorating. Sherri’s recipe for buttercream icing was really good and a recipe I will continue using if I am decorating a cake. My galaxy cake ended up using about 1.5 batches of this recipe. Make 1 batch in the beginning and another batch after you make the crumb coat.

Yield: 0

Buttercream Icing

Buttercream Icing


  • 1/2 Cup Crisco
  • 1/2 Cup Butter
  • 1 TBL Karo Syrup
  • 1 tsp. Vanilla
  • 1/2 TBL Milk
  • 1 LB Powdered Sugar


  1. Mix together butter and Crisco until blended.
  2. Add Karo syrup, vanilla, and milk. 
  3. Slowly add in powdered sugar. Until blended well. You want the icing to be a little stiff. Add a little more milk if too stiff.

This cake was so much fun to put together and I learned so much from Sherri about cake decorating and I am going to share with you what I learned.

Assembling The Galaxy Cake Layers

Placing the cooled cake on a cooling rack we started assembling the cake. To frost a multi-layer cake, make a ring of frosting around the first layer with a piping bag (no tip is needed). Then using a frosting spatula, put a nice sized dollop of frosting the center to spread to the frosting edge you made.

Repeat the process for the other layers.

Once you have all the layers together, you can pipe frosting in any gaps you may have.

Now thin out your frosting with a tiny bit more milk. You want the frosting a bit thinner for the crumb coat for the sides and top.

To smooth the crumb coat you can put your frosting spatula in hot water so it “melts” and smooths the frosting. You can also use a piece of paper to smoother the frosting as well.

Place the cake in the fridge for awhile so the crumb coat can get solidified.[su_box title=”Related Post” style=”soft” box_color=”#005530″ radius=”0″]10+ Star Wars Gifts for the Foodie in Your Life[/su_box]

Galaxy Frosting

Make the second batch of frosting and separate into bowls for coloring. We used 4 colors: black, blue, purple, and red.

Using the frosting spatula, put dollops of each color along the sides of the cake. Put them wherever you want. This part was super fun for me as there is no right or wrong way to do this. It is your creation!

After you have the colored dollops in a way that you like, use the spatula to smooth. The galaxy will magically appear as you smooth and swirl. I did have to add some more splotches of color as I put too much black and didn’t like that.

Now the hard part put the cake in the fridge for a few hours. For the mirror glaze, you need the frosting to be really hard.

After the glaze is made, separate into bowls for coloring. Before you start pouring the glaze on the cake, make sure the glaze is cooled completely or it will melt your frosting. We used the same food colors for the glaze.

Since I didn’t want to completely cover the side, I just dripped enough of the glaze to have drips along the side. Pour one color at a time. I know some other recipes mix the colors together before applying to the cake but I wanted more creative control of what was going on. Either way works great!

Once the glaze was on, I added some LEGO Star Wars mini-figurines and edible glitter for even more prettiness. I loved the way the cake came out, especially for my first attempt. It is not that hard and I would make this again.
