I saw this cute idea and had to make one of my own. I know that pie in a jar is really popular, but cake?… it is WAY easy! Just take an 8 oz canning jar, shove a cupcake (baked without papers) in the bottom, layer with frosting, another cupcake and more frosting. I put some sprinkles in for a surprise on top. A note, ribbon, and a spoon top it all off! These are SO easy and just look so creative. These make great gifts! Just try not to lick your fingers!
