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!

Delicious recipe! I switched the brown sugar for coconut sugar and added a half cup of walnuts for additional flavour. The recipe was crumbly, at first, but I let it cool down completely and served each piece in a paper muffin tin. Thanks for a recipe I am sure I will be making again!

I am so glad you liked them! The walnuts sound fabulous.

Brown sugar oatmeal bars made this recipe when I needed something sweet but had very little in the cabinet so I added a pinch of lemon extract, 3/4 tsp baking cocoa & almost 1 tsp sea salt just out the oven YUMMY great summer sweet

Easy on-hand ingredients but I feel they’re lacking something 🤔. Very tasty and sweet for sure. I might try again and add some honey or peanut butter.

Either would be delicious! Let me know how it goes.

These are really delicious. A couple of things. Mixing the batter with a spoon or similar tools leave this a bit dry. But if you mix it with your fingers to better distribute the butter, it makes it much easier to use. Also, next time I make this, I’m going to double the recipe and divide between two 8 x 8 pans. These are pretty thin, and I’d personally prefer they be a bit thicker (I made them to take on a train I commute on for breakfast and it would be easier for them to be a bit less delicate). I’m absolutely making them again!!!
