Chocolate Peanut Butter Swirl Bundt Cake

peanut-butter-chocolate-bundt-cake-recipe This peanut butter swirl bundt cake is for The Hubs. The man loves all things peanut butter, and since its our anniversary this week, I thought for once I’d actually make something with him in mind. Don’t get me wrong, he gets to eat everything I make, but i’m pretty sure lentils and soyrizo would not be topping his request list.

Thanks for being a good sport all these years honey.

I had this idea for peanut butter ganache with the thought in my head that, “of course they sell peanut butter chips at the grocery store!” Well, yeah, I soon found out not every store sells them.  If you have a hard time finding them, there’s always Amazon. Don’t skip it! The cake itself is not peanut buttery enough without it in my opinion.
