Peanut Butter Banana Bars with a Peanut Butter Cream Cheese Frosting

 Peanut Butter Banana Bars with Frosting-1

On Sunday night Price, Autumn, and I headed down to Rhode Island to Lincoln Woods State Park to meet our wedding photographer, Lefebvre Photo, for our engagement photo session.

In practice of late, I was not prepared at all. #ugh #storyofmylife

We went out to Kohl’s in the morning to get some coordinating clothes, mainly plaid shirts and a dress for me to wear. Of course, I couldn’t find anything to wear. I don’t mean I couldn’t find anything that I liked since I basically LOVE all of Lauren Conrad’s current line. I mean, I couldn’t find anything I wanted to wear for the photos. Of course!!! So mini meltdown later, I rushed out to Gap Factory Store and Old Navy after lunch and threw together a $6 white tank top, with a $12 (originally $45!) sweater, some jean capris and sperry’s. And wished I had a Xanax.

Thankfully, the photo session was fun since I was a ball of nerves. The location was amazing with shafts of golden light shining through the trees. The leaves were a lovely mix of greens, oranges, and yellows above us and below our feet. Our photographer was great with setting up shots and getting us to joke around when deep down I wanted to throw up from nerves and just the thought of how corny all of it was. I went to college and worked with Danielle years ago so it definitely helped keep me semi calm as we recounted the worse boss in the history of bosses. Plus, we got to talk about our babies as her daughter is just 2 weeks older than Autumn. Besides Danielle’s wedding and engagement photography she also takes newborn and baby photos so incorporating Autumn into our photos was really easy. I’m looking forward to getting our photos in a few weeks. I’ll be sure to share them when I get them 🙂

Anyway, these bars are so delightful! They are the perfect combination of flavors. I think peanut butter and banana are best friends, better than peanut butter and jelly. Yep, I said it!!! Jelly is great but too sweet at times, and you can’t dip jelly into a jar of peanut butter, like how you can with a banana… wait, you don’t do that? Err, me neither…

These Peanut Butter Banana Bars are one of the best ways to use up past their prime bananas. I swear we always have past their prime bananas. I’d assume I should buy less bananas but when I do it’s the week Autumn has decided she wants 2x as many as usual and then I need to get more anyway. It’s like that when we buy milk… if I buy a 1/2 gallon for a month and we run out every week I’ll then buy a gallon and we will only drink a glass before it goes bad. #thestruggle

I loved the texture of these bars that the banana and the oats give it. The oats make it feel like fall. I[‘m sure that doesn’t make any sense but it totally feels like a fall treat. Now, that doesn’t mean you can’t enjoy it all throughout the year but if you have it I’m sure you’ll think “Man, I gotta make these again this fall.”

Seriously, this frosting.

You can skip the frosting but then we wouldn’t be friends as the frosting adds to much to the bars to enhance the flavors and texture. I just love biting into the bar and getting my teeth through the frosting first before getting to the fluffy bar. Plus, frosting always wins.
