Scrumptious cookie bars filled with marshmallows, oreos and mms. The perfect mishmash of sweets for a special treat.
These "Mad Scientist" cookies were such a hit a few weeks ago when my son Colin and I made them. The idea behind them was all him. We were having a new front door put in, the heavy duty all iron type and it was nonstop noise for hours so I thought a fun distraction would be a good idea.
*updated 5/13/19. We now make them as cookie bars, which is better for the marshmallows!
It pretty much went like this:
Me: Colin do you want to go make cookies? (as if there was any answer but yes)
Colin: yes! cookies! (followed by a rambling of all the flavors he wanted)
Me: What do you want to put in them?
Colin: m&m's! marshmallows! chocolate! cake! sprinkles!
So we scoured the pantry for supplies. I had a lot of treats from the previous week, my girlfriends came over and we made caramel apples and watched (talked throughout) Hocus Pocus.
Colin picked out m&m's, mini marshmallows and oreos. I wasn't really sure this was going to be the best idea, but he's almost 4 and I knew he'd enjoy us following out his creative plan. I had a couple thoughts while mixing all the candy, first was that when it bakes it could be a big flat blob of goop, second that they would completely stick (story of my life), or third I'm not a baker I have no clue what I am doing.
I have to tell you...these were awesome! They were chewy and delicious and with each bite you got a little taste of each ingredient. I kept the oreos pretty chunky, I suggest this.
The batch was gone by the next day, I gave half away and my family ate the other half. I'm pretty sure I went to boxing that night, working hard for all my cookie eating sins.
