I used this today to make cupcakes. It made 3 dozen cupcakes rather than the 2 dozen I usually get from a boxed mix. Kudos!

I recently used the Cake Mix Extender when making my daughters birthday cake , used as recipe instructed and was so thrilled to have a whole pan full of cake ,yes it rose to the very top of the pan ! And the taste was great ,needless to say it didn't last long,lol.
They have cut down the size of a standard box cake mix from 18 oz down to
13 oz and it seems from the taste that they have also cut the sugar as well the Cake Mix Extender fixed both of these problems , Thanks so much for this recipe it's one I will go to every time I stir up a boxed cake mix !

Just a heads up, if you make this recipe you will also want to make frosting extender (3 Tablespoons butter, 1/4 cup confectioner sugar, 1/8 teaspoon vanilla) or whipped cream extender, 1/8 cup heavy cream whipped.

I have been doing this with the store bought boxed cake mixes for years ... ever since they decreased the amount of cake mix in the box but not the price ... and I either have to back 2 9x13 to feed my flock or I used the extender recipe and can bake 1 boxed cake mix with extender in my 15x10 :) They still don't last long around here ... but that's okay ... that tells me they must be good!

This works like a charm! I live at high altitude so I make a tiny adjust ment to the leavening agents. This extension results in a lofty 9x13 cake - something that's unpredictable and often lacking at 6,300 ft.

LOVE this!!! It worked like a charm and really does make a cake mix cake really tall - perfect since I've always wanted just a bit more height in my cake mix cakes. I will totally be using this recipe again. Thank you so much for sharing it!

So excited to try this!!! I mixed this up for a box of betty crocker butter cake mix with pudding. I got 2 huge single-layer cakes. However, the moistness of having pudding in the cake mix was watered down. Will try again next time with a few teaspoons of pudding mix to retain the cake's moistness. Mthks for sharing this!!!

This turned out excellent. I used this extender to make a monster truck cake for my son's birthday. It was double layered strawberry & chocolate. I added some extra cocoa to the chocolate and followed the rest of the instructions exactly. The cake turned out awesome, huge, and delicious. I have never had compliments like this with cake. I wish I would have taken pictures of the inside before it was devoured, the think pink and brown layers looked beautiful. Thanks so much, I will never make a cake again without using this extender. Wondering how it would turn out with a brownie mix?

This is a thifty way to get more for your money. I cannot tell the difference from the original. Thanks for saving us all a lot of money.
