This is another one of my favorite cakes! I made this cake for my daughters 9th birthday party. She was having a slumber party so I knew I had to come up with something really cute. This is my medium size sheet cake, half chocolate and half yellow cake with cream cheese icing and fondant polka dots. I used Twinkies covered with fondant for the girls sleeping bags, marshmallows for their pillows and vanilla wafers for their heads. My daughter is in the middle and all of her little friends are around her. She and all the girls LOVED the cake!
