Mmmmm Peanut Butter Cup Cake!

I got this idea for this cake off Pinterest. I couldn't not try it especially when my brother said he wanted me to make it for his birthday. Since it was such a large cake I decided to do it for my husbands and my brothers birthdays....my brother likes vanilla cake, so the top layer cake was vanilla and the bottom layer was mocha. The interior layers had crushed up peanut butter cups as well as the outside layers. It was covered in peanut butter buttercream and chocolate ganache. It was a big hit amoung our family!!
