I made this Dora the Explorer birthday cake for the biggest Dora the Explorer fan, my daughter, for her second birthday.
I traced the characters onto rice paper from several different pictures in a coloring book. After the cake was frosted, I put the rice paper transfer onto the cake and added all the colors.
