HELP! Rap song I heard today!

I've heard this song twice in the past week on mixes on my local rap station, but I can't figure out what it is.

The chorus goes something like "Got that cash, got that cash, got that cake, got that cake, feelin great", then "she can get it" like 6 times.

I also know that one of the lines in one of the verses is "Life so sweet I'm gonna need a dentist" or along those lines.

PLEASE HELP! I NEED to know this song!
Thanks in advance.
