Peanut butter lovers, this one is for you.  These Peanut Butter Cookie Bars are sinfully delicious. 

They just taste so darn good.  I swear, it is hard for me to resist just eating one.  Seriously, I just can’t do it.  In fact, I’m already on my third batch this week because I can’t stop munching them!  

Growing up we never made peanut butter cookies because my sister is allergic to nuts. I remember the first time I ever ate a peanut butter cookie I was in high school.  I went over to my best friend’s Peanut Butter Cookie Barshouse and we whipped up a batch.  We followed the recipe on the back of the peanut butter jar.  And Oh My Goodness! I couldn’t believe how good peanut butter cookies were!   *So sorry, sis, this one just ain’t for you!

These Peanut Butter Cookie Bars have such a great texture.  They are just the right amount of soft and chewy.  The peanut butter flavour is right on. And my-oh-my does it ever go down well with a large glass of milk!

These cookie bars are so easy to whip up. With a new baby and a toddler I need quick and easy recipes and these Peanut Butter Cookie Bars fit the bill. They are just so dang easy to make!

You need 5 mins to prepare and 20 to bake! So easy!! Check it out:

First, using your electric mixer combine the melted butter and the sugar.

Third, sprinkle in the salt and toss in the flour.  Mix it all together for a minute or so.  You will have lovely peanut buttery dough. Friendly tip:  You may want to gently mix in the flour with the batter before turning on the mixer.  You know, to prevent a cloud of flour from rising from the bowl!  Now, spread the dough evenly in the prepared baking dish by patting it down with your hand or with a spatula.

    I made these today and they are cooling. I doubled the batch and but subbed in 3/4 c. (measured as 1/4 c. + 2 T.) brown sugar Splenda blend to try to cut back on the sugar amount without altering the texture too much. Also baked for 4 extra minutes and that seems perfect (barely brown around the edges). The boy asked for peanut butter cookie bars for his birthday so I hope these won’t disappoint!
