In a video by How to Cake It, a giant surprise inside hedgehog cake filled with candy and chocolate is showcased. The video demonstrates the process of creating this unique and delicious cake.

The cake begins with the creation of a patterned hedgehog design made out of chocolate cake, which forms the outer shell of the cake. The cake is constructed using vanilla buttercream as the adhesive for the different cake layers.

The fondant is carefully molded to resemble the texture and shape of a hedgehog, complete with its adorable little face and spikes.

Inside the cake, there is an abundance of candy and chocolate treats, including mini chocolate bars, chocolate dragees, and individually wrapped candies.

To enhance the visual appeal of the cake, the top is decorated with chocolate spikes to mimic the appearance of a hedgehog's quills.
