How Many Cups of Cake Mix Are in a Box?

There is no clear-cut answer to this question. The truth is, every boxed cake mix will have a different number of cups inside. That said, you need to pay attention to the brand you’re using and the size of the cake mix.

For example, Betty Crocker’s boxed cake mix tends to have four cups of cake mix. However, this is because it is a very thin batter and requires an extra ¼ cup of water. Therefore, it essentially needs four cups of cake mix to create a tasty baked treat.

On the other hand, a brand like Duncan Hines only has three cups of cake mix. It is a lot hardier and doesn’t need extra water like the Betty Crocker version. That said, it can rely on less cake mix to create your beloved cake. Duncan Hines can have anywhere from three to six cups.

Overall, though, you can expect your boxed cake mix to have anywhere from three to six cups of cake mix. The best thing to do is to check out your box. It should tell you how many cups of cake mix are inside. 

If not, you can always discover for yourself how many cups. To do so, simply pour the contents of the box into a measuring cup. This will give you a sure answer that you can rely on. From there, you can use your knowledge to divide the ingredients into half the recipe.

Or simply share with your friends the cool new information you just discovered. Depending on your friends, this could be a hit or miss. (In which case, you might need to find new cake-loving besties).

    Michelle:

    Stumbled on you website and it looks like a great resource for information for me.

    I recently made Rum Cake that I found online and it turned out fantastic. In making it I did not follow the recipe exactly so I adjusted some of the ingredients.
    The recipe called for a box of Duncan Hines Butter Golden cake mix (15.2 oz) which I did use.
    However here are the changes I made:
    1/2 cup of vegetable oil…. I used 1/2 cup sour cream
    I also added 1/2 cup of low fat butter milk.
    The Cake was great!

    I want to make another Rum Cake and I wanted to bump it up even more so I took to YouTube to see the various recopies that people made that felt were great and to pick up any ideas to enhance my next cake.
    In making this next cake I have to make some adjustments since I have some family members who have a wheat allergy. I will be making this cake tomorrow so it will ready for this Easter Sunday meal.

    I know there are a number of different “Gluten Free” cake mixes out there but the one I am using for this cake is Krusteaz Gluten Free Yellow cake mix (18 oz) which is 2.8 oz’s larger.
    You’ll Need:
    3 eggs
    1 1/2 cups milk
    1 stick melted butter

    I will be using the Krusteaz Gluten Free Mix so that my family members can eat this wheat free cake.
    However I also plan to make the following adjustments to making this cake:
    Instead of the stick of melted butter…….1/4 cup Kerry Irish butter
    I 1/4 cups milk……converts to 1/2 cup sour cream, 1/2 cup low fat butter milk, 1/4 cup water.

    In watching other videos making spiced rum cake I also plan to add 1/4 tsp cinnamon, 1/4 nutmeg, and 1/4 tsp fresh ground cloves to help bump up the taste!

    I also am considering adding 2 tbsp orange juice and 2 tbsp orange zest.

    I also will attempt to make this same recipe from scratch using King Arthur’s Gluten Free Cake Mix at another time to see how that recipe turns out.

    While I know it will be awhile until I hear back from you hopefully and input would be appreciated.

    Any input and suggestions will be greatly appreciated.

    Thank You !
    Michael

      Hi Michael,
      Your ideas sound lovely! I’m glad you’re experimenting with baking this cake, as that’s half the fun of baking!
      I like the idea of using orange juice/zest to give it some flare.
      Have you thought about using brewed coffee in place of some of the liquid?
      How about adding some nuts, like walnuts or pecans?
      Let me know what you think!
      Happy baking,
      Michelle
