My stepmother usually has to make two of these cakes at a time. It may take two days to make but it takes no time for it to vanish from the table!

Oh my goodness, this cake was way too yummy! Made it for Easter and everyone loved it. (Did use fat free sour cream and lite cool whip though)

I love this cake! So did my whole family. I made it for Christmas and it was devoured. I actually got the recipe from a family friend. I added more Cool Whip bc I'm not a huge fan of sour cream. Delicious!

I made this cake for my Mom's birthday. It was so good it took my breath away and hers! Wow! AMAZING cake! I didn't have a white cake mix, so I used a coconut flavored one. It still turned out fabulous!
