Pin a Day: Peanut Butter Monster Cookie Bars

It's been a little while since I made these Peanut Butter Monster Cookie Bars, but they still deserve a post.   I made these bars for my team at work a few weeks ago.  I joked that these were the "clean out the pantry bars," but it wasn't entirely a joke.  I used chocolate chips, peanut butter chips, and white chocolate chips that I found in the pantry.  I started out by doubling all my ingredients so I had enough for a 9x13 recipe.  I knew that an 8x8 wouldn't do.  I heated and cooled the butter and mixed it with the eggs, sugar, and vanilla.  Next, I added in the peanut butter.  Mine was low fat, so it was slightly runnier.  Next, I added in the flour and other dry ingredients.  Finally, I mixed in the various chips and dark chocolate M&Ms.  Finally, I poured it all into a pan and baked for about 28 minutes.  It was a big hit at work.  The middle pieces disappeared first, which seems typical.  It was very rich, so I couldn't eat a very big piece and it would have been even better with milk.  This was a great way to clean out the pantry and proved to be a great treat for my friends.
