I love Mason Jars and they can be a great way to take cakes with you or even share with friends and family. 
In this tutorial I show you how to layer the cake and I use my delicious Banana Cake Recipe combined with Caramel and walnuts, and your favorite Buttercream Recipe.

I added in the video some information about a company

that I fell in love with. They sell products to recap mason jars. The have Recaps that are in plastic and doesn't rust great for on the go and many other uses. Click
