Creating This Oatmeal Raisin Cookie Bar Recipe
What have I been craving for the past two weeks? Oatmeal raisin cookies. Like. Every. Day.
So it wasn’t any shocker that when it came time to make another goodie I chose to whip up some of these gluten-free Oatmeal Raisin Cookie Bars.
I was not disappointed.
These easy peasy oatmeal cookie bars are soft, chewy, ooey, gooey and filled with cinnamon vanilla flavor. I love that this recipe requires no scooping and you can bake the dough all at once rather than having to sit there glued to the oven, waiting for batch after batch of cookies to bake.
I literally made these from start to finish in 40 minutes while feeding my kids breakfast, getting myself ready for the day, and sending them off to school. A serious no fuss treat for sure!
So the next time you are craving a treat but you don’t hardly want to lift a finger, these bars are definitely for you. And I wouldn’t be surprised if you eat the entire pan yourself.
Ingredients for Oatmeal Raisin Cookie Bars
Because these are gluten-free cookie bars, you do need a few special ingredients to make them. Luckily, gluten-free baking is becoming much more common so you can likely find all the necessary ingredients at your local supermarket.
- Granulated sugar and brown sugar
- Vanilla extract
- Brown rice flour
- Potato starch
- Oat flour
- Tapioca starch
- Baking powder and baking soda
- Xanthan gum
- Old-fashioned oats

Can I Use Instant Oats?
I prefer using old fashioned oats in this recipe rather than quick cooking oats because it yields more texture in the bars, and I am all about a little crunch and chew in my cookies. I think instant oats would make the dough too dry and wouldn’t add much in the way of texture.
Can I Use All-Purpose Flour?
Using all-purpose flour would eliminate the need to add all the starches, alternative flours, and xanthan gum. That’s a lot of tweaks to the recipe.
I’ve only made these oatmeal raisin bar cookies as written, so I can’t speak to whether or not this recipe can be made with regular all-purpose flour.
How to Make Oatmeal Raisin Cookie Bars
These really are the best cookie bars, and they don’t taste gluten-free whatsoever! Here’s how I make them:
- Melt the butter, then combine with the egg, granulated sugar, brown sugar, and vanilla extract.
- In a separate mixing bowl, sift together brown rice flour, potato starch, oat flour, tapioca starch, 1 teaspoon of cinnamon, baking soda, baking powder, xanthan gum, and salt.
- Add dry ingredients to the egg mixture and mix until combined.
- Using a spatula or wooden spoon, stir in oats, raisins, and chopped pecans.
- Scoop dough into a greased 8×8-inch baking pan.
- Bake until golden brown. Set on cooling rack to completely cool. Once cooled, cut into slices.
The above is simply a quick summary of this recipe. Check out the free printable card at the bottom of this post for all the detailed instructions.
Can I Make the Cookie Bars in Advance?
Yes! These oatmeal raisin bar cookies stay tasty for longer than a traditional cookie. I don’t know about you, but I only like cookies the day they are baked. They tend to get stale and crumbly after that.
Not these babies. I ate one tonight, 4 days after making them, and they were still soft and tender. A definite bonus after all that “not so hard work” to make them.
Tips for Making Gluten-Free Cookie Bars
- If you have the extra time and ingredients on hand, it really makes a difference to soak the raisins in a tablespoon of apple juice and a few shakes of cinnamon. It intensifies the flavor of the bars and makes those raisins plump and juicy.
- To ensure the oatmeal raisin cookie bars are completely gluten-free, make sure to buy oats and oat flour that are labeled as such.
- You need to let the bars cool completely before slicing into them. Because the bars are gluten-free, they need time to set up properly first.

If your raisins are hard, you can soak them in 1 tablespoon of apple juice and 4-5 shakes of cinnamon for an hour or heat them with the apple juice and cinnamon in the microwave for 30 seconds to soften. It adds more flavor as well.
