I’m so glad that you seemed to enjoy my new weekly blog series!  It makes me so happy to have a way of staying connected just a little more regularly.  Definitely let me know if there are any other topics you would like me to include!

Peanut Butter Banana Cake Bars with Cream Cheese Icing

So these cake bars are another item I made when filming for eHow.  In case you aren’t familiar with what happens when you film any kind of cooking how-to, you actually have to make everything at least twice.  There has to be a final product to show in the short time you have to film, but you also have to make everything while filming.  I sent the film crew home with leftovers, but was still left with a crazy amount of desserts after the fact.

Well, when Matt was helping me clean up, I decided to taste a bite of the version of these cake bars I’d made a few days earlier.  They were still really, really good.  It was at that moment that I told Matt he had to take the plate away immediately.  I knew I was in trouble.

The cake bars are moist and flavorful.  I added the peanut butter chips because without them, the peanut butter flavor in the cake is very subtle.  You actually don’t need the cream cheese icing, but really, you always need cream cheese icing.
