Cake in a jar is made by baking cakes in small glass jars and packing them up safely to ensure that the freshness of the cakes is kept locked. These cakes, if prepared properly, can last for several months at room temperature. Refrigerating them extends the duration further.

The very first thing needed to prepare a cake in a jar is of course, a jar! As every task has its set of rules, same goes for this as well. These cakes are usually prepared in small glass jars or mason jars. The jar used must be wide mouth and pint sized so that the baking is uniform.

The glass jars used must be free of dirt and fine chips on its surface and on the inside. They should be sterilized in boiling water to ensure proper cleaning. The lids used to seal these cakes must also be boiled to ensure a zero-bacteria package.

Once the jars are ready for baking, the desired cake’s batter is poured into the jars till the jar is half full. They are then placed into the oven in a water bath. The water bath ensures uniform baking along the bottom of the jar & the sides.

Once the preparation time is reached, check if the cakes are done by pricking a long toothpick into them. Cake in a jar is usually kept at a high temperature even after baking to ensure any germs present in the ingredients of the cake will be killed. When the jar is slightly warm, clean its sides with a cloth and securely seal the jars with their lids. The steam which gets locked into the jars keeps the cake soft and fresh even after a month of baking.
