"Pokemon Pokeball" "Oreo Brookie" Birthday Cake

Made this for my grandson's 14th birthday which was today. For those not familiar w/the oreo brookie, it is a layer of brownie mix w/whole oreo cookies baked into it. Before that layer is completely baked, you take it out of the oven after about 15 mins then spread your chocolate chip cookie dough on top then place it back into the oven for another 40-45 minutes. Thought it would be a cool idea to make it into a cake for the grandson. This is 2 layers filled & iced w/whipped white chocolate ganache then decorated w/white chocolate fondant.
