I recently made these Soft baked oatmeal squares. They were quick to put together and tasted great.
A couple changes I made were that I used chunky peanut butter since that’s what I had on hand and I used mini Reeses pieces since I grabbed the wrong bag at the store. I also did not put the glaze on top.
They can be wrapped individually and kept in the freezer if you are not planning on using them soon.
There are a variety of recipes in cookbooks and online so you can have some variation in your rotation of snacks. You could use the basic recipe and add different flavored chips, etc.
