I found this video on YouTube, and it inspired me to attempt my own gluten-free version of this Captain America Cake.
Now that I purchased a cake leveler and a turntable, I am going to try again. I didn’t split the red, white, and blue evenly. This time, I’ll use two boxes of King Arthur Yellow Cake Mix instead of one. Hint: The difference between yellow cake and white cake is egg yolks. If you want a white cake, only add egg whites. I added an extra egg white because I didn’t add the yolks.
Will keep you updated on my next attempt!
