The Very Hungry Caterpillar Cake. "On Monday, he ate through one apple. On Tuesday, he ate through one pear. . ." One of my favorite children's books! So cute, so simple, so hungry! Here's a huge version of that book that we created for a special first birthday. We handpainted the caterpillar and fruit to give it the same look as the book. Inside was moist red velvet cake with cream cheese frosting.
