What makes food colouring drizzle down a cake?
There’s also a trick to use a little bit of jello before baking the cake. You take a little of the baking mix (a cup or so), mix it with food coloring or jello, and drizzle it on top of the rest of the cake mix in the pan. Use a knife to stripe the cake with designs and neat lines. When the cake is done you’ll have thin colorful stripes and lines in your cake and a pretty design on top (which you won’t see if you fully ice it, but still is good!) Edit: I got jello and other ingredients confused. The method I originally described you would either add food coloring the the portion of the cake mix you took out or some kind of flavoring or other cake mix (like chocolate, for example). It would still make for streaks in your cake that would go down into the cake. The jello method does indeed involved making pinholes with a fork or toothpick and pouring the jello onto the cake. See this pic and if this is the result you’d want then that’s how you’d do it:
