Hi guys! While I am out here in California learning all things neuroscience, a few of my blog friends will be here all week sharing some yummy treats with you.

Today, Julie from This Gal Cooks brings you chocolate chip peanut butter marshmallow bars! But before you hear from Julie (and hear all about these delicious looking bars), I just wanted to let you know that she is one of a kind. She is ridiculously nice and approachable! She is also always willing to help with all my million blogging questions (Thanks Julie!) and I’m so lucky to call her my friend. As if that wasn’t enough, she makes me drool every week with her creative recipes. Her meals are on constant rotation on my menu plans…like her easy bolognese sauce is now a staple in my kitchen. I am so glad she is here today to share with you her love for sweets!

Chocolate Chip Peanut Butter Marshmallow Bars

Hi folks! I’m Julie from This Gal Cooks and I’m thrilled to be guest posting on Zainab’s blog today! I met Zainab a few months ago and she has become a great bloggy friend of mine! Today I will be sharing a recipe that contains two of my favorite indulgences: chocolate and peanut butter! I hope you enjoy these Chocolate Chip Peanut Butter Marshmallow Bars!

Chocolate Chip Peanut Butter Marshmallow Bars

Let me tell you a little about me before we get to these delicious bars! I started blogging in June of 2012. When I first started blogging, I pretty much lacked photography skills. My photo shoots consisted of me quickly snapping a photo with my iPhone. Eventually, I realized that I needed to acquire some photography skills in order to showcase my food in a way that made the food look as good as it tastes! I did some research online, purchased a DSLR camera and a lens and the rest is history! Every day I strive to improve my photos. I try out new layouts, different angles, and sometimes different lighting. I recently purchased a macro lens and it has allowed me to capture shots that my little hundred dollar 50mm lens prevented me from capturing!

  • Camera: Canon Rebel T3 DSLR
  • Lens: Canon 100mm Macro IS USM Lens, Canon EF f/1.8 50mm lens

I blog about food. I guess it’s pretty obvious with a name like This Gal Cooks! I also enjoy crafts and design but I don’t have much time for them with working full time, attending school part time and blogging full time! My blog contains recipes ranging from savory dishes to sweet treats that will make you swoon. I have a weakness for cookies and a passion for creating delicious, simple meals that often will feed a small family for more than one day. Leftovers and easy meals are a must when you’re a busy gal like me!
