Use bold buttercream hues like pinks
purples
and blues to create Dora's trademark style.
For a genuine look
hand-pipe Dora's face and other details
or use edible photos.
Use recipes that result in a light and fluffy texture to make sure the cake itself is moist and soft.
In addition to buttercream
you might want to use fondant to give Dora's dress a crisp
polished appearance.
To surprise and excite
include fillings within the cake that are colorful or themed
such as chocolate ganache or fruit preserves.
