DIY Jar Cake_3

Mason Jars – the new DIY it item brought to you by Pinterest. I’ll admit it; I love them. They’re the most versatile DIY item out there. You can put almost anything in a mason jar, pretty it up with ribbon, burlap or twine and impress a crowd.

I’ve been known to use mason jars for plenty of projects, including the Salad Bar I pulled together for a bridal shower last month, and baked smores in a jar. This week, I wanted to try something a little more DIY… enter Mason Jar Chocolate Cake.

Let me start by saying, not everything turns out the way you expect it to – even for me. Sometimes, it really is an experiment and if it turns out I feature it on the blog.

I learned a few lessons during this experiment:

1) It never turns out the way you imagine it will

2) Don’t buy mason jars that don’t have measuring markers

3) Cake rises – a lot

I ended up making 4 mason jar cakes, each of which rose to a different level. I then came to the conclusion that even though the jars didn’t have measuring markers, about half way full of unbaked cake mix would be just about right [especially for frosting-lovers]
