I'm new to making cakes and I can't seem to layer my cakes without them falling into pieces while I'm trying. I've been using the boxed cake mixes until I get the hang of it and quit wasting cakes. Am I not baking the cake enough or is it too moist? Am I supposed to actually put one cake on top of another or do I cut one cake horizontally? Am I supposed to freeze the cake before layering it? Any tips or links would be great!

Maybe try wrapping the layers and refrigerating overnight? That might firm up the cakes before layering.

I refrigerate my cakes between every step and they still taste moist and yummy when they are served (at room temp). It makes them easier to work with, and transport.

I don't know exactly how new you are to making cakes, but in case you're really new, be sure to level your cakes before layering them.

By new to making cakes, I mean that I've never done much other than the typical homemade birthday cake.

When putting one layer on top of the other, do I need some type of support or should I be able to transfer it by hand?

I too use boxed cake mixes. I have these thin plastic flexible cutting boards that I use to slide under the cake layer after I torte it. They work great!

I freeze them and they handle beautifully!

I like to freeze my cakes before layering. My cakes are ALWAYS moist, so don't let that worry you. I like to use a cutting board or a flat cookie sheet to slide between the layers to lift the top one off. I have also used a cake board too. HTH and good luck!

Why don't you describe every step you are doing for us, from the moment the cakes come out of the oven, and we'll be better able to troubleshoot it for you.
