Noah ate rainbow cake, right?  No?  Well kids should when learning about Noah’s Ark.  This cake was made from a boxed mix, but it would be very simple to make a rainbow cake without paying extra for a fancy box and some food coloring packets.  Essentially, it’s a white cake mix which is divided evenly into six different bowls.  Each bowl is tinted with food coloring to match the colors of the rainbow (remember ROY G. BIV?).  If I were to use my own dye, I’d use the cake decorating kind.  It’s much more potent than those little droppers.  Here’s the boxed mix we used, in case you want to find it yourself.

Anyhow, after the individual bowls are tinted, it’s time to get creative.  If you’re making a round cake, like I did, you start by spooning your red cake batter into the middle of the pan, letting the weight of the batter push it out toward the edges.  Next, drop the orange batter right in the middle of the red, which will push the red out even further.

Continue with all the colors, being careful not to drip batter into the other colors.  Though really, it’s not the end of the world if you do.  If you’re using small round pans, you’ll have enough batter for two pans, so distribute the batter accordingly.  If you’re baking in a 9″x13″ pan, do the same process, but make multiple circles, placed randomly in the pan.  Then bake according to package directions.

To top it off, we used Funfetti frosting that just happened to include rainbow-colored sprinkles.

Update: I’ve since made a 9″x13″ version of this cake, and here’s what it looked like before going into the oven.  The colors are slightly muted because I used the food coloring in the little dropper bottles, which isn’t quite as intense.
