Libby and her girlfriends made a tie-dye cake when she was home and it turned out great.  It's not that it was that delicious, but it was really a lot of fun to look at.  The colors were super vibrant and beautiful.  I had it on my instagram story and received several comments on how to make one.  SO, I put together a little tie-dye cake story here. :)

I used a white cake mix and divided it into 6 cups.  Used food coloring to tint the batter.
Poured each color into a 6" cake pan.
Repeated 2 more times!
Layered and decorated.  (I think I should take a cake decorating class.)
The colors are not as vibrant and I am sure it is because I did not use as much food coloring.
I think I could have been neater when filling the cake pans to look less like a project my kids would have made when they were younger!
Anyhow, it was really a fun cake to make AND eat!  And in the end... it's really all about the frosting.
