Tie Dye Swirl Cake

I did a cake order for a sweet 16 party over Halloween.  The birthday girl was doing Halloween colors with polka dots.  I thought I'd add a little element of surprise when they cut into the top layer of white cake by dying the batter different colors.

First, I separated the batter into 3 different bowl, and left 1/4 white in the original bow.  I added drops of food coloring...

 Mixed it up...

 Then started dropping spoonfuls of the colored batter randomly in the cake pans.

 I took a knife and swirled the batter around in the cake pan just a little before  baking.
 And this is what it looked like after it was all baked and leveled...

 

This was the cake all decorated...

 *This coloring effect can also be done with cupcakes!
