Cake – How many cups of batter does a cake mix make

Normally, you spoon cake mixes in because you need to be very careful to preserve all of the air you have incorporated into the mix. This air is very important to the structure and overall appeal of the cake.

It's not to say that you can't pour in the mix, it is just not best practice.

Quite frankly, there are some cakes where it won't really matter. If you are baking a standard Duncan Hines or other store bought mix, it doesn't really matter. Those have so many emulsifiers and extenders that you would have to work at deflating them.

However, if you are doing scratch cake mixes, you have to treat them like a nice man treats his wife, that is - very gently. Very, very gently. Hence, always spoon the mix.

Hope this helps

If you are only over by a small amount (¼ cup or less) just add half the volume of flour(±). If you added a moderate amount of extra water(½ to 1 cup) add half the volume of flour and ½ tsp baking powder and sugar equal to ⅓ the flour. Cakes fixed this way will be slightly dry but serviceable, particularly given that you started with a boxed cake anyway.

Beyond that point just make a double recipe.
