Assemble the birthday cake in a jar by placing a small amount of cake into the bottom of four small canning jars. Top with one color of frosting, a bit more cake, and the second color of frosting. Top each jar with a seal and lid. Store in the fridge for up to 2 days. Serve with candles and a lot of birthday wishes.
