Old-Fashioned Oatmeal Bars

Old-Fashioned Oatmeal Bars is an easy Mix-n-bake recipe ~ perfect for breakfast or a snack to add to the lunch box

Old-Fashioned Oatmeal Bars

It is that time of the year where my son is almost done with his studies for the year. Only one more test and he can relax, meaning relax from his studies as he is also working full-time.

Every year around this time, he also ups his time spent in the gym and is always ravenous when he gets home. He goes to the gym straight after work and gets home a while before we have dinner.

I like to keep these old-fashioned Oatmeal bars on hand for him, to grab whenever he feels the hunger pains can not wait any longer.

He would usually pack a couple of bars together with his lunch as well in the mornings.

I, on the other hand, am a huge snacker and these gooey Oatmeal bars are just perfect for me to snack on. A little better than last nights leftover dessert, right ?

And it is Oatmeal after all, which is breakfast …

Chocolate Chip alternatives:

You can leave out the Chocolate Chips and replace them with Raisins or dried Cranberries, which is also delicious in these snacks.

I have to be honest, I would rather have either the Choc Chips or the Cranberries as neither myself or (especially!) my son are big fans of Raisins. Okay in some desserts and even savory dishes, but not in this kind of treat.

I bake the bars slightly longer than necessary as I like the extra bit of crunchiness it adds to the edges. And I am not talking 10 – 15 minutes here, only about 5 minutes at most.

The bars are ready when the color is golden and if you press slightly down it should feel a little springy. On baking the dough will rise to about twice the size, but will settle back to the original thickness on cooling.

You might also want to slice the baked piece into bars when you remove it from the oven dish, but do not try to move the pieces apart as it will only break. This needs to cool down completely before you can safely handle them by hand.

Can you use old fashioned oats (not instant or quick cooking)?

Lynne, yes you can use old fashioned oats. Before baking let the mixture sit for 20 minutes to blend and moisten the oatmeal

These bars are a definite keeper. I added cranberries, almonds and currents and cut sugar in half. I baked for 25 minutes and they are crunchy and hold together perfectly. Used margarine instead of butter. Making another batch tomorrow with raisins and walnuts to “hide” in the freezer!

I just made this recipe. It looked very dry in the bowl and I was concerned it would be difficult to get it to stick together. I re read all the comments etc. I added a half a cup of dried cranberries and chopped walnuts instead of chocolate chips. The dough did not rise and it came out of the oven very dry. I did cut when I removed it from the oven as you suggested and it’s obvious something is wrong. I imagine the ingredients will have a nice flavour but the end result doesn’t look anything like the picture you provided.
