My mom offered to help me out and baked two cakes for my daughter's birthday. She enhanced the recipe and I know she greased/floured the pan but for some reason they are stuck! 

I dont have time to read a million forums and the last 3 websites I looked at had plenty advide for "next time..."    I dont need advice for next time, just need some advice/suggestions on how to get these two cakes un-stuck, without breaking, within the next 2 hours!!! THANK YOU!!

warm the bottom on the stove for a minute to "melt" the pan grease? Cut around the edge with a knife.

Might need to bump the side hard  too to make it shift a little after you loosen the edge.

yes what jenn123 said -- then if it breaks and it really might no worries -- spread some buttercream into the cracked area --  then just get a spatula with a flat edge and scrape out the piece/s that stuck and set them into place onto the icing -- bam! it's done all the time -- you got this -- and if the cake is chocolate and you have chocolate icing it's a less noticeable save but whatever -- it will hold together and all is well --

best to you and most of all -- don't panic (anymore) ♥

Yes to all of the above!  Even if a big hunk doesn't make it out  you can always scrape it out and reposition it.  If your cake is moist enough it will still cut well and make it onto the plate.

If you had more time I would have suggested freezing it. I have had this issue with my Nordic Ware gingerbread man loaf pan and Nordic Ware rose pan with some recipes.  Freezing then sitting the pan briefly in hot water and thumping hard a few times has resulted in the cake/loaf coming out clean.

Not that this helps you now but I tend to line my pan bottoms with parchment if at all possible.

Hope all goes well and happy birthday to your daughter!

I agree with squirlley cakes for the future. Use parchment to line the bottom. Also don't leave your cake in the pan for a long time after it cools. I try to get them out as soon as they are room temp.
