Why you need to make this recipe:
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.
This giant oatmeal cookie can double as a birthday cookie as well!
What you need to make this:
- Gluten free oats - Use rolled oats, not quick oats.
- Gluten free flour blend - most brands will work in this recipe but don't use any gluten free flour blend with bean flour.
- Butter - Use vegan butter if you are dairy-free.
Can you use this oatmeal cookie batter to make regular sized cookies? Of course!! You can also make regular sized cookies out of this cookie dough if you don't have a cast-iron skillet.
Step by step recipe directions:
It is so easy to learn how to make a skillet cookie! Not only are cookie skillets easy to make, they can be used for birthdays and celebrations too!
Step 1: Add all dry ingredients to a bowl. Use a whisk to blend thoroughly. Make sure your whole rolled oats are certified gluten free!
Step 2: In a separate bowl, add all of the wet ingredients and whisk to blend.
Step 3: Add chocolate chips or raisins. Pour the wet ingredients into the dry ingredients and mix well.
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 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 cookie sheet or an 8x8 baking pan, this recipe is for you!
Topping ideas:
- Dolce Leche sauce (I buy it at Trader Joe's)
- Hot Fudge
- Bourbon Butterscotch Sauce (see the picture below!)
- Old-Fashioned Vanilla Cream Sauce
Expert Tips and Recipe FAQ:
You can easily make this cookie recipe drop style. To do this, line a baking sheet with parchment paper. Use a cookie scoop to drop balls of cookie dough onto the parchment paper.
You can make this cookie recipe dairy-free by using a vegan stick butter in place of the regular butter.
I do not recommend using quick oats because your cookie will be mushier.
This skillet cookie will keep up to 4 days in an air-tight container, or up to 4 months in the freezer.
Why certified gluten free oats are important:
I can't stress enough how important it is to use certified gluten free oats. Regular oats are very easily cross-contaminated with gluten every step of the way from growing in the fields, to harvesting equipment, to silo storage.
There are many brands of certified gluten free oats, even Trader Joe's has them!

Can I make this in any other type of baking dish if I don’t own a cast iron skillet? Like a 9x13 pan as “cookie bars?” If so, what’s the cook time?
Sandi Gaertner
Hi Heather, you would probably want an 8x8 pan. Have a good evening :-).
