Just wondering what it is & how it works. All I've found in searches is people asking about it, but I've seen it mentioned in posts & wondering if there is a recipe for it or if that just means adding sour cream, pudding, or jello, etc?

Would just like as much info as possible.

Here is the recipe I use and I use it with the Pillsbury cake mix.

A cake extender is ingredients added to a box mix that stretches (or extends) the recipe to yield more batter. Most produce enough batter for 3, 9x2 inch layers. Hope that was helpful.

Also the extender makes the cakes slightly denser and taste more like homemade. I'm an extender convert and will never make a cake without it.

I'm not sure. I have only tried it with the white cake mix. I don't see why you couldn't though.

I will often use one of the extender recipes. It helps to have plenty of cake so that I feel more comfortable leveling my cakes. (I always worried before that if I leveled them, they would be too skinny.) Or if I need just a bit more, like for a 9" or 10" cake.

It also makes just a slight difference in the texture, which I really like. Maybe just a little bit denser.

Also, it can help with the flavor. A good resource might be the Cake Mix Doctor book (as well as many great recipes here on CC). She lists simple ingredients to add to mixes that enhance the flavor/texture also.

I used basically the same extender this weekend. You are supposed to use whatever flavor you want, devils food, strawberry, etc. I only had a white cake mix and wanted chcolate so I added a cup of cocoa. It was really good.

I love extenders. I doubt I'll ever go back either.

The 2 cake extender recipes I use are on the cc site under recipes. The first for yellow/white is by Lilscakes and the other one for chocolate is by candy120 it is a cake extender 2. I use Duncan Hines cake mix most of the time but I'm sure you can use these extenders with others too.
