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:
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 certified 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.
Certified Gluten Free Oats Are Critical:
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.
Certified gluten free oats are grown with a purity protocol to ensure they do not get exposed to gluten.
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
Tips For Success:
- Let the batter sit in the skillet for 15 minutes before baking. This will help soften the rolled oats.
- Be careful not to overbake this cookie.
- Use gluten free frosting to pipe decorations for a birthday.
This is the 10-inch cast iron skillet that I own. It is perfect for cooking dinner and dessert! It can easily go from the stove to the oven.

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 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

What’s does a stick of butter weigh please? In my country they don’t sell butter by the stick. Thanks.
Sandi Gaertner
Hi Bob, A stick of butter is the equivalent to 1/2 cup or 113.4g
Heather
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 :-).

Jessica
I didn't think bourbon was gluten free, is there a specific brand you use to make the sauce?
Sandi Gaertner
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
