A while back I saw rainbow cake baked in a mason jar and fell in love.
At that moment I knew for my sister's baby shower I would attempt to bake cake in baby food jars. How appropriate!
Bright Pink, orange, and blue are her colors and with the help of the new neon food coloring on the market (gasp! sorry all-natural food coloring, you just didn't work for this party!) I was able to achieve just that. It was actually quite easy. Spray the jars with a non-stick baking spray and fill with batter. I layered my colors but didn't pay too much attention to being perfect. I wasn't looking for stripes just colorful fun cake. It's important to fill the jars just shy of the halfway mark to ensure that it doesn't rise up and leak over the sides while baking. That wouldn't be so pretty. I used 4oz jars which is the perfect snack size equivalent to a cupcake. After filling the jars, place on a cookie sheet, or in a cupcake pan, and bake. After they have cooled completely top with a dollop of frosting.
I like that the whole sweet treat is contained in the jar. You could even put the lid on, cover it with a coordinating piece of fabric, tie a ribbon around it and use it as a cute baby shower favor!
Ours were placed on the dessert table next to a pile of bright orange spoons (you need a spoon to eat the cake out of the jar) to enjoy while watching the big present-opening-event.
