How To Make Small Cake With Half A Box Cake Mix

Whether you are interested in baking a smaller cake or just hate ending up with lots of leftovers, making half a cake mix is an excellent solution. But how to make half a box cake mix?

In some circumstances, you do not need a whole box of cake mix. Instead, you can simply use half of the box of cake mix to make a smaller one and save the other half for some another time.

Standard cake mix can be too big for a small group of people and can leave you with lots of leftover cake, especially if you are preparing it for only one or two people. So to avoid cake wasting, you can make a small cake.

Cook’s Tips

Tip #1:

Let’s make one thing crystal clear. The results can vary slightly depending on the type of cake mix. So it is not a bad idea to check the cake to see how it actually turns out.

Along with that, the baking time will also depend on your oven. Checking for doneness always require attention rather than relying on a timer.

Tip #2:

The cake mix’s unused part should be kept in a ziplock bag to keep it fresh for the next use. It is a good idea to mark a date on the cake mix box as a reminder when you did open it.

Try to use it within the next couple of weeks. Even if the smallest amount of air gets into it, the packaging will start degrading the ingredients, which is the main culprit for cake not rising as much as you would like.


You might find it useful to adjust the amount of oil, milk, or water added next time you use the half box of cake mix to make your half cake per your taste.
