Today is all about this incredible giant gluten-free oatmeal cookie, aka a gluten-free pizookie. I like to call it a “pizookie” because it resembles a pizza. Any way you call it, my kids go crazy over this gluten-free pizookie recipe!
The bigger, the better!! This gluten free skillet cookie is so easy to make. All you need are a few simple ingredients like certified gluten free oats, brown sugar, butter, gluten free flour, chocolate chips or raisins, an egg, vanilla, and cinnamon.
I have been experimenting with baking in my cast iron skillet lately. I love how easy it is to bake with this skillet. It retains heat beautifully, making your baking turn out even. I had a cast-iron skillet for a long time that sat neglected under my stove for years.

Allergen Information:
This big oatmeal cookie is gluten-free, nut-free, and soy-free. You can make this cookie recipe dairy-free by using vegan stick butter in place of regular butter.
Cookie Baking Tips
1. Let the cookie dough sit for 15 minutes to allow the oats to absorb some of the moisture.
2. Lightly grease the cast iron skillet so the cookie doesn’t stick.
3. If you use a baking pan, use an 8×8 pan lined with parchment paper.
4. Use gluten free frosting to pipe decorations for a birthday.
See my Gluten Free Cookie Troubleshooting Guide and my favorite Cookie Baking Tools for even more cookie baking tips.
There are a few brands of certified gluten free oats, and they are all good. I mostly buy this because you get four bags for a lower price.
Ingredient Notes:
- Gluten Free Oats – Use rolled oats, not quick oats. Be sure your oats are labeled gluten free!
- Gluten Free Flour Blend – Most brands of gluten free flour will work in this recipe but don’t use any gluten free flour blend with bean flour. You can use my DIY Gluten Free Flour Blend if you need a gum-free blend.
- Brown Sugar – light or dark brown sugar both work well.
- Butter – Use unsalted butter. Use vegan butter if you are dairy-free.
- Eggs – Use size large.
- Vanilla Extract – I recommend using pure vanilla extract.
Gluten Free Oats Are Critical:
I can’t stress enough how important it is to use gluten free oats. Regular oats are easily cross-contaminated with gluten every step of the way, from growing in the fields to harvesting equipment to silo storage. Gluten free oats are grown with a purity protocol to ensure they do not get exposed to gluten.
Topping Ideas:
If you are an ala mode person like me, you are going to want a gooey sweet sauce to drizzle over your gluten free oatmeal pizookie cookie. Here are some fun ideas for sauces:
- Dolce Leche sauce (I buy it at Trader Joe’s)
- Hot Fudge
- Bourbon Butterscotch Sauce (see the picture below!)
- Old-Fashioned Vanilla Cream Sauce
Step-By-Step Directions:
It is so easy to learn how to make a skillet cookie! Not only are cookie skillets easy to make, but they can also be used for birthdays and celebrations!
Step 1: Add all dry ingredients to a large
Step 2: In a separate smaller bowl, microwave the butter for 25-30 seconds. Combine all of the wet ingredients and whisk to blend.
Step 3: Pour the wet ingredients into the dry ingredients and mix well. You will get a cookie batter that isn’t too firm.
Step 4: Pour the cookie dough into a greased cast-iron skillet. I like to use coconut oil to grease the skillet. Spread the batter out so that it is evenly disbursed, and bake the skillet cookie for 18-20 minutes at 350º F.
Because you are baking this cookie dough as a giant cookie, you will need to bake this cookie longer than small cookies. If you don’t have a

Notes
- I have tested this recipe with King Arthur Measure for Measure GF, Bob’s Red Mill 1 to 1 GF blend, and Authentic Foods Multi Blend. That doesn’t mean others will not work, I just have not tested other flours.

What’s does a stick of butter weigh please? In my country they don’t sell butter by the stick. Thanks.
Hi Bob, A stick of butter is the equivalent to 1/2 cup or 113.4g
Can I make this in any other type of baking dish if I don’t own a cast iron skillet? Like a 9×13 pan as “cookie bars?” If so, what’s the cook time?
Hi Heather, you would probably want an 8×8 pan. Have a good evening :-).
Sweet! I’ve never tried to make a skillet like this but it looks increadible succulent, especially your Bourbon Butterscotch Sauce ?

I didn’t think bourbon was gluten free, is there a specific brand you use to make the sauce?
Hi Jessica, Thanks for writing. Research goes back and forth a lot on whether whiskey is gluten free. I like two articles. One is https://www.verywell.com/is-bourbon-gluten-free-562408 Gluten Dude’s take on this: http://glutendude.com/alcohol/what-alcohol-is-gluten-free/ I do not react to whiskey, nor does my husband. I hope this helps. Sandi
