Please read my disclosure policy. Incredibly simple and delicious oatmeal cookie jam bars. These bars come together in less than 30 minutes and only require 6 ingredients! Today, I’ve got some super simple and delicious blackberry oatmeal cookie jam bars. These bars are so simple and take just minutes to make. They are the perfect last-minute dessert to bring to a brunch or surprise your Mom. And they can all be mixed up in one bowl. I love when that happens! Minimal dirty dishes and super quick clean-up. Basically the base is just a butter, sugar, and flour mix. A little over half of that base gets pressed into the bottom of a pan. Then jam gets spread on top. For the jam you can use whatever flavor you would like! If you don’t have a blackberry jam or don’t like blackberries, feel free to use whatever flavor you do like. I’ve done these bars with raspberry and strawberry and loved those flavors too. Whatever you prefer. One thing to make sure you do is line the pan with parchment paper. When these bake the jam will seep out along the edges and if you haven’t lined your pan it makes for an interesting challenge trying to remove these. I speak from experience on this one 🙂 Not too many other directions are needed – these live up to the first word in the title – simple!
