    Today is all about this incredible giant gluten free oatmeal cookie. Some call these big cookies a "pizookie" because they resemble a pizza. Any way you call it, my kids go crazy over this gluten free pizookie recipe!

    The bigger the better!! Just look at this Gluten Free Pumpkin Skillet Cookie.

    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.

    This gluten free cast iron dessert recipe is fail-proof! Even better? This oatmeal skillet cookie is going to become a family favorite!

    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:

    If you love cookies, you will want to try all of my delicious gluten free cookies recipes on the blog! And...if you love big cookies, wait until you try this incredible Gluten Free Skillet Cookie recipe!

    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:

    oatmeal skillet cookie ingredients
    • 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!

    dry ingredients in a bowl

    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.

    Wet ingredients poured onto the dry ingredients in a bowl

    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:

    Can you make this recipe as drop style cookies?

    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.

    Can you make this dairy-free?

    You can make this cookie recipe dairy-free by using a vegan stick butter in place of the regular butter.

    Can you use quick oats?

    I do not recommend using quick oats because your cookie will be mushier.

    How long will this keep fresh?

    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!

    More gluten free cookie recipes:

    This delicious bourbon butterscotch sauce also tastes amazing on this Gluten Free Blond Brownie too!

    • If you can't decide between a brownie or a cookie, these Gluten Free Brookies are a great compromise cookie.
    • These Gluten Free Sugar Cookies are made drop style so they are quick and easy to make.
    • If you love a melt in your mouth cookie, these Gluten Free Russian Tea Cookies are one of my favorites.
    • Who can say no to these Gluten Free Nutella Linzer Cookies? Nutella is so good in them.
    • My regular gluten free oatmeal raisin cookies recipe makes the best Gluten Free Oatmeal Cream Pies too.

    • 1 ¼ cup gluten free flour blend * see note
    • ¾ cup gluten free whole oats * see note
    • ½ teaspoon cinnamon

    Instructions

    Notes

    1. 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.
    2. If your gluten free flour blend doesn’t contain Xanthan Gum or Guar Gum, please add 1 teaspoon.
    3. To make this recipe dairy-free, substitute the butter for vegan butter.
    4. It is critical to use certified gluten free oats if you are Celiac. Cross-contamination runs high in regular oats.
    5. This cookie will keep up to 4 days in an air-tight container, or up to 4 months in the freezer.

      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?

        Hi Heather, you would probably want an 8x8 pan. Have a good evening :-).
