Making this on a family vacation. Should I adjust anything for altitude?!
Hi Brittany ~ I honestly haven’t tried baking this at higher altitudes… if you give it a try, let me know how it turns out!
Can this be done in an oven instead of the crockpot? I’m needing to make a dessert for about 80.
Hi Vanessa… absolutely! It works really well in a 9×13 dish. You can follow the instructions here to get an idea of how to bake it in the oven…

Hope that helps! 🙂
Can I double this in a large crockpot?
I think it could change up the texture, but if you try… let me know how it turns out!
Can I use 1 can of filling ?
You can, but it may be a little dry and will just have less of that classic gooey dump cake texture.
So what size crockpot? I have a 4 & 6 qt.
Hi Walter ~ I’d recommend your 6 quart for this recipe. Enjoy!!
