Remember when we talked the other day about allergies? My co-worker, Jenn, and I continued that conversation after she hosted an almost entirely gluten-free Super Bowl party to accomodate her good friend who can't eat wheat. She even made homemade wings, starting with fresh, uncoated wings, dusted them in corn flour and spices and deep fried them. She said it wasn't hard at all; it just took a little thought and planning. 

Recently, I helped to organize a girls night out in honour of three friends birthdays' and one of those friends is allergic to chocolate. I asked Jenn for advice, as she is internally known as our Ace of Cakes, and she suggested subbing brown sugar for white in my batter and glazing the finished product in butterscotch and sprinkling with Skor pieces. Absolutely drool-worthy.

As per usual though, I got distracted by an idea on Pinterest and had to give it a try. Though it comes in many methods, a rainbow cake tutorial is surprisingly easy to follow. Starting with a white cake batter (boxed or homemade, your choice), you divide it into as many bowls as you want colours. In my case, I used five. 

Then colour to your heart's content. Most of the online links I found suggested using gel food colouring instead of the liquid kind. What a difference. Though the gel is a big more pricey (I bought a variety pack of colours at Bulk Barn for $13.50), you use so much less of the colouring that you'll be able to do many pojects with one set of gels. I used less than half a teaspoon for each bowl to make the insanely vibrant colours.

I generously greased two nine-inch round cake pans and layered my batters, one colour at a time -- half in each pan -- and baked them as per my recipe. Once cooled, I frosted the cake in white.

The best part, of course, was watching the birthday girls cut the first slice and reveal the whimsical interior. I can't wait to try this again with different colour combinations, maybe shades of green for St. Patrick's Day?

What's the most adventurous or spontaneous recipe you've tried lately?
