Oatmeal Cream Pie Gooey Bars

I’ve been wanting to bake with Oatmeal Cream Pies for forever. I absolutely love them. Every time I see them in the grocery store, I want to buy the whole box and devour them right then and there.

I just love the taste and chewy texture of those little cookies.

So when I thought about what to make with them, I wanted to make sure you could still taste those amazing little oatmeal nuggets. Eventually I arrived on these bars.

With layers of crisp oatmeal cookies, oatmeal cream pies, nutella, mini marshmallows and three kinds of chocolate chips, I knew they’d be awesome! Plus, it’s all smothered in sweetened condensed milk. The mother of all that is sweet!

This is one of those funny instances where after baking them, I almost threw them out. I initially thought they were a big fail. And I was about to be super disappointed.

I was getting ready to take pictures and started to cut into them. They are the epitome of gooey! And when looking at them, it seemed like the oatmeal cream pies got lost.

But then I bit into them.

Oh. my. goodness. The flavor is sinful. Indulgent. Amazing. And the oatmeal cream pies do not get lost.

Oatmeal cream pie, nutella and white chocolate and cinnamon chips combine to make the most delectable bar. And with as gooey as they are, they stay moist and delicious for days and days.

So what I initially thought was a fail ended up being the opposite.

They were a huge hit with my neighbors too. They couldn’t stop eating them right along with me. So stinkin’ good. Even better than I imagined. If you like oatmeal cream pies and sweet things, you have got to make them. You will love them!
