Gluten-Free Chocolate Chip Cookie Bars Ingredients & Substitutions

As always this recipe is gluten-free and vegan. That said, I do test each recipe with “regular” ingredients and make notes of alternatives or swaps so that everyone can enjoy it.

Here are a few key ingredients for these gluten-free chocolate chip cookie bars but make sure you scroll all the way to the bottom recipe card for the complete ingredient list.

Flour: I made this with XO Baking Co. gluten-free all-purpose flour blend. Note: gluten-free flour blends can vary in weight so I recommend measuring by the cup. If you are not gluten-free, swap the flour with regular all-purpose flour.

Cornstarch: A touch of cornstarch helps keep these chocolate chip cookies bar thick and chewy. This can be substituted with arrowroot, tapioca, or even potato starch.

Butter: I enjoy baking with Becel plant-based bricks but any vegan/dairy-free butter substitute will work. Use regular salted butter if you are not vegan or dairy-free.

Flax Eggs: To keep this recipe vegan, I used two flax eggs. This is made by combining 2 tablespoons of ground flax seed with 6 tablespoons of warm water. If you are not vegan or egg-free you can use 2 large room temperature eggs instead.

Chocolate Chips: I adore using Pascha vegan chocolate chips but any brand, type, or size of chocolate chip will work in this recipe. Use whatever best fits your dietary/lifestyle needs.

Step By Step Instructions

1. Preheat the oven to 350º F and prepare an 8×8-inch pan with non-stick baking spray and parchment paper.

2. Combine the butter, brown sugar, granulated sugar, flax eggs, and vanilla extract in a large mixing bowl and mix until smooth.

3. Add in the flour, cornstarch, baking soda, and salt and mix until a soft dough forms.

4. Gently fold in the chocolate chips and spread evenly in the prepared pan. Top with a few additional chocolate chips if desired.

5. Bake for approximately 30 minutes and allow to fully cool. Enjoy!

Vegan Chocolate Chip Cookie Bar Tips & Tricks

Removal: For easy removal, prepare the baking pan with non-stick baking spray and 2 pieces of parchment paper. Use the parchment paper edges as handles to gently remove the bars once fully cooled. Note: You can place the bars in the fridge to cool faster.

Baking Time: The key to delicious chewy chocolate chip cookie bars is to ever so slightly under-bake them. Check them at the 25 minute mark and if the edges are golden and the center appears almost set take them out and see if a toothpick comes out clean or with a few moist crumbs. If so, they are done. If not, put them back in to bake for a few more minutes.

Do you enjoy an extra ooey gooey texture? Check the bars at 20 minutes.

Parchment Paper: Do not skip on the parchment paper. Spray the pan with non-stick baking spray and ine with pan with two pieces of parchment paper. This is going to make removal so much easier.

Run a butter knife around the corners of the fully cooled gluten-free chocolate chip cookie bars and use the overhanging parchmant paper as handles to gently lift the bars out. And remember, do not attempt removal until they are fully cooled.

Cutting: Looking for a clean cut? Ensure the chocolate chip cookie bars are fully cooled before slicing. With a large sharp knife, run the knife blade under hot water for 10 seocnds, wipe it clean, and make the first slice. Continue this pattern until fully cut as desired.

Easy Chocolate Chip Cookie Bar FAQs

Will This Recipe Double?

Absolutely. If you would like to double the recipe use a 9×13-inch baking pan. Note: baking time will increase.
