Ingredients Needed for These Gluten-Free Birthday Cookie Bars

Paleo Flour: My favorite is Bob’s Red Mill brand and this is the brand I used! I like to get my gluten-free flour staples from Thrive Market because they have great deals! If you use my link, you can get 40% off your first order.

Coconut Sugar: This is my favorite refined sugar-free option!

Honey: I love the flavor of honey in my baked goods, but if you do not eat honey you can substitute with maple syrup.

Plant Milk: Any plant milk would work here!

Olive Oil: I love to bake with olive oil, but you can also swap with avocado oil or coconut oil here.

Vanilla: I love to buy my vanilla extract in bulk from Thrive Market (see above for 40% off your first box). If you have histamine issues, getting a non-alcoholic vanilla extract may be helpful for you!

Baking Soda: Make sure your baking soda is labeled gluten-free!

Salt: My favorite salt is Redmond’s Real Salt. I have linked it here and you can get 15% off with code LESSWITHLAUR.

Vanilla Frosting: I am so sad because Simple Mills discontinued my favorite frosting, so I have been using Miss Jones or homemade vanilla frosting for this.

Sprinkles: I always make sure to look for naturally dyed sprinkles!
