When my son said he wanted a Darth Vader birthday cake, I started searching online for directions, only to find none. I found tons of sites suggesting this special cake pan and pictures of finished cakes with no directions. I didn’t want to disappoint him, but I also didn’t want to spend a bunch of money on a cake pan I’d only use once.
So I got out the cake pans I had, traced their shapes on paper, cut and pieced them together until I came up with my own Star Wars-inspired DIY Star Wars Darth Vader Cake. It was a big hit and went perfectly with our Storm Trooper Cupcakes.
Have your own Star Wars fan at home? This Darth Vader cake idea is sure to be a huge hit at any DIY Star Wars birthday party.
To make your own Darth Vader cake you will need:
- 9 Inch Square Cake Pan
- 9 Inch Circle Cake Pan
- Serrated Knife (I used my bread knife.)
- Black Cake Icing (I used 2 packages of this one.)
- White Decorating Icing
- Your Favorite Cake Mix (1 box)
- Wax Paper (optional)
DIY Darth Vader Cake Tutorial:
Bake cake mix as directed, pouring half the batter into your circle cake pan and half into the square cake pan.
Allow cakes to cool completely and remove from cake pans. Pop the square cake into the freezer for one hour so it is easier to cut without crumbling issues.
Once you remove the square cake from the freezer, cut triangles off from opposite corners of the cake. Position these at an angle from the circle cake as show in the picture below. To make your triangles the same size, simply cut one, flip it over and use it as a guide to cut your second triangle so they are mirror images of each other. (My triangles were 7 inches at the longest side and close to 5 inches on the side facing out.)
Next, cut another triangle from the bottom angle of your square cake. This will form Darth Vader’s chin.
Cut the remaining portion of the square cake in half. Use one piece of this to fill in the area above Darth Vader’s chin.
Use the other half to cut pieces to fill in gaps you have left. (Hint: If you slide a piece of waxed paper under those spaces you can use a pen to draw the shape onto the wax paper, cut it out and use it as a pattern to cut the cake pieces.)
Use a bit of frosting to hold the pieces of the cake puzzle together. Then cover in black cake frosting. I couldn’t find black in the canned frosting I usually buy, so I bought 2 of these decorating icing packs. You could also use chocolate frosting and add a bit of black food coloring.
Once your cake is covered in black frosting, use white decorating icing to add facial details.
This Darth Vader birthday cake was a huge hit at my son’s 7th birthday. It pairs really well with the Star Wars-inspired Storm Trooper cupcakes we made.
