With just a handful of simple ingredients and a couple minutes of prep you can have these delicious oatmeal bars in the oven and ready to devour! They make a perfect grab and go breakfast for busy mornings. 

You could also serve them with fresh fruit and yogurt for a leisurely breakfast. Or pack them for an easy answer to the mid afternoon slump or after school treat for the kids!

By now we all know there are a few ingredients I can’t help but to love.  Of course I can’t help but to put brown sugar in things when I have the chance.

There’s the brown sugar peach cobbler and zapple crisp  to show as an example of that. I just love the depth and warmth it adds to a recipe.

Even deeper than my love of brown sugar is my infatuation with oatmeal. I mean it’s healthy, super versatile and I live the texture it adds to food.

If you are a regular here, you know baked oatmeal is a staple on our breakfast table.  Some baked oatmeal is dense or dry, but we like ours soft and fluffy.

Favorites include brownie baked oatmeal, maple pumpkin oatmeal and pineapple right side up baked oatmeal just to name a few.

But we don’t only eat our oats baked. There is also room in the table for favorites like apple pie steel cut oats and healthy chocolate oatmeal.

Oooh, and there are cookies too. We can’t forget the cookies! A lot of our favorites include oatmeal. Take monster cookies, and great-grandma’s oatmeal raisin step-ons for example.

But these brown sugar oatmeal squares might be the most versatile of all.  They could be served at a sit down breakfast or be grabbed on the way out the door for a quick morning bite.

They also make a perfect treat to tuck in your purse for a little snack at work or between errands. Have some ready for the kids when they get home from school to help give them the energy to power through homework or practice.

You could even serve them as a simple dessert for when you need a little something sweet but don’t want to go whole hog. There are just so many great ways to enjoy them!

Made these years ago, were delicious my kids loved them. Made them today, followed recipe exactly. Did not turn out, just a pile of crumbs. Can you tell me what I did wrong?


Monday 6th of May 2024

I wish I knew. I hope you saved the crumbs though, the would still be delicious on yogurt or something!

Has anyone tried this with steel cut oats ?


Wednesday 3rd of April 2024

I would think steel cut oats would be a little tough/crunchy. But if you give it a try, let me know if I'm wrong.

I've heard this called Rickety Uncle. People seem to like it more as a topping for yogurt, fruit, or ice cream than by itself, like a dessert granola.

Delicious!! Had to cook for about 25 mins in order to get the whole 9x13 to ‘bubble.’ Probably not an issue with two smaller pans. Plus I sprinkled a little sugar on top to get a caramel texture coating. Not trying to be healthy in this house when it comes to dessert!!🤣❤️
