Oatmeal Chocolate Chip Cookie Bar Ingredients
- Butter: To keep this recipe vegan, we use vegan butter. If you are not vegan or dairy-free, feel free to use regular butter in these oatmeal chocolate chip cookie bars.
- Flax Seeds: Since this recipe is vegan, we don't use eggs. Instead, we use something called flax eggs.
- Flax eggs are simply made by a mixing ground flax seeds (you can find this in the baking section of almost any supermarket) and warm water together. The combination creates a gel-like substance that works as a binder in vegan baked goods. If you are not vegan, feel free to use one regular egg in this recipe.
- Milk: To keep these oatmeal cookie bars vegan, we use plant-based milks such as unsweetened almond milk or oat milk. If not vegan or dairy-free, feel free to use regular milk.
- Sugar: We recommend using organic cane sugar in this recipe. Alternatively, you may use purecane sugar substitute.
- Vanilla: For that classic chocolate chip cookie flavor.
- Baking Powder: To give our chocolate chip cookie bars a little lift.
- Oats: Quick oats add a hearty texture to this recipe. We do not recommend using steel cut oats as they don't bake as well as Quick Oats.
- Flour: We recommend using regular or gluten-free all purpose flour in this recipe.
- Chocolate Chips: Use regular or vegan semi-sweet chocolate chips. We love the brand Enjoy Life.
How To Make This Recipe
Step 1: Begin by making the flax eggs. In a small mixing bowl, mix the ground flax seeds with the warm water and set aside for 2 minutes until a gel forms. Then, preheat the oven to 375 degrees.
Step 2: In a large mixing bowl, mix the melted vegan butter, sugar or purecane, flax eggs, plant-milk, vanilla, salt, and baking powder together. Add the flour and oats and mix until a batter is formed. Fold in the chocolate chips and then transfer the batter into a greased baking pan.
Step 3: Bake for about 25-30 minutes or until the bars are completely cooked and golden around the edges. Allow them to cool before slicing and serving warm.
Frequently Asked Questions
We recommend storing leftovers by allowing the bars to cool completely and then wrapping them in plastic wrap. Keep them at room temperature for 3-5 days. You may also freeze for longer storage life and reheat them in the microwave to serve.
No problem! Try using melted coconut oil instead of the vegan butter in this recipe.

I cannot find King Arthur measure for measure flour in Canada. Can I substitute with another gluten free flour?
Jillian says
Cup4Cup and Arrowhead Mills both make great gluten free all purpose flours!
Mimi says
Made these today and they were a huge hit. So very delicious! I was out of my usual no-sugar substitute, so I just used 1/2 less real sugar. Since I don’t normally cook with oil, I used half oil and half liquid Just Egg and I added a bit more soy milk until it was the right consistency. I can’t wait to make these again. Such a yummy recipe!!

Can I use something else besides the flax seed meal?
Karen says
Have you ever tried it with flax milk? I’m assuming it wouldn’t change anything…?
Jillian says
Hi Karen, I haven't tried this recipe with flax milk but I don't think it would change anything 🙂
