m&m's oat squares


It’s the last Bank Holiday of the Summer – and yet again the grey clouds have been looming all day!!

We did have plans for a family drive up to Cavan Lakes, but by the time  everyone (the kids) fell out of bed and got breakfast it was late afternoon. They were up late into the night playing Mario Cart on the Wii of all things. My eldest son found the “lost”console down the back of his wardrobe when he finally got around to cleaning his room!  This so-called “lost'” games console has been missing for 2 years, and  has been the subject of many arguments between my boys over who was responsible. I even got the blame at one stage.

Since the trip wasn’t happening, my hubbie decided to do some DIY, the boys are back on the Wii (there’s a championship at stake), my daughter Amy and I headed to the kitchen to bake.  Amy was trying out a new stir fry recipe for dinner so I decided to make some M&M’s Chocolate Fudgy Squares for dessert or “afters” as we call it.




These fudgy chocolate squares are made with oats and everybody’s favorite M&M’s.  Now I have tried these out with Smarties but I find the colour fades on the smarties when you bake with them  – so I always use M&M’s  when I’m baking cookies are squares like these.


M&M's Oat Squares Stacks



These super easy oat squares take less than 10 mins to put together, (no mixer required) and 25mins in the oven. The hardest part is waiting for them to cool to cut them up, but I promise you they are worth the wait!
