Ingredients & Substitutions
- Gluten-free flour blend: I tested with Pamela's Artisan Blend, Bob's 1:1 gluten-free, and Namaste perfect blend flours. Make sure to select a flour with Xanthan Gum already included.
- Butter: This recipe could easily be adapted to dairy-free with a dairy-free substitute of your choice, such as Earth Balance buttery sticks.
- Oats: Always choose oats that are certified gluten-free as regular oats are not gluten-free.
- Chocolate chips: if you need dairy-free, consider Enjoy Life brand.
Easy to Make
Making these bars is as easy as: Mix, Dump, Bake!
- Cream the butter and sugars, then mix in the remaining wet ingredients.
- Blend in the dry ingredients.
- Stir in the oats and chocolate chips.
- Spread the dough into a parchment-lined 9-inch square pan and if you're feeling extra, sprinkle with a few more chocolate chips.
- Now, it's time to stick that goodness into the oven!
- Bake until the cookies are golden brown.
Expert Tips
- Although they are hard to resist when they are warm and gooey, allow the bars to cool in the pan before cutting into squares. If you cut them when they are too warm, they might crumble apart. When they are cool, they will hold together better!
- This recipe calls for a 9-inch square pan. You could easily double the recipe for a larger batch and bake in a 9x13 pan.
- Store the cookies at room temperature in an airtight container for up to 3 days. After that they become a little stale.

Glad to have you! Thanks so much!

I made the recipe as is, but unfortunately it was too crumbly. The flour blend I used contained xanthan gum but I would suggest adding an additional 1/2 tsp.
Great taste though.

Thanks for the feedback Diane. Sorry you had a little trouble. As I'm sure you know, all GF flours act a little differently!
Mary :
The bars smell and taste wonderful. A winner!
