My son wanted a Batman theme. I thought this was easy enough. I just used a box cake mix to make 2 cake rounds and stacked. I used concentrate yellow food coloring first – way too gold. Started over with new icing and dropped in the liquid drops and that yellow came out great!
I used black concentrate food coloring to tint white icing (and it sparkled). Then traced bat cutout and piped and filled in the logo. Lastly I sprinkled yellow sugar over the cake very lightly.
This homemade Batman birthday cake is easy and delicious with homemade Chocolate Chip Buttercream filling!
