This mini caramel apple oatmeal skillet cookie is a fun way to serve a delicious fall-inspired cookie in a 6-inch cast iron skillet! Oat flour, almond flour, and rolled oats make the cookie gluten-free friendly. Honeycrisp apples swimming in maple syrup caramel make the cookie irresistible! Top with your favorite ice cream for a wonderful seasonal dessert.
caramel apple Oatmeal Skillet Cookie
Aren’t cookies served in a mini cast iron skillet the cutest?! Sure, a good old fashioned drop oatmeal cookie like the pumpkin oatmeal chocolate chip cookie is great. But, talk about a fun way to serve and eat dessert.
However, this caramel apple oatmeal cookie isn’t my first adventure into baking in a skillet. I first got the clever idea with my mini cherry skillet cake, fudgy skillet small batch brownies, and the skillet got even cuter (and smaller!) with the mini dutch baby recipe.
The cookie is super soft and chewy on the inside, yet it has a wonderful caramelized exterior that make it spoon-worthy.
Maple Syrup Caramel Apples
The caramel apples are truly what make this oatmeal skillet cookie divine. Not only do they add tremendous flavor, but they give the cookie texture and a little bump of sweetness.
For the apples
I like to use Honeycrisp apples for baking. They are the apples I use in most of my apple recipes, including the caramel corn apple galette, gluten free apple spice cupcakes, and the popular apple biscoff crisp.
What I love about Honeycrisp apples is they combine the perfect balance of sweet and tart. And as the name implies, they are crisp which lends to a nice bite in your dessert! Plus, they are readily available for all of your fall baking!
For the caramel
We use my beloved maple syrup for the caramel to the apples. It’s not dissimilar to my maple syrup caramel sauce recipe. The only difference is that I go all in and use butter for this skillet cookie. I love the richness of the butter, and it plays a complementary role to the fresh apples.
The result – a silky and creamy caramel sauce spiked with fresh apple juices and fork tender apples that keep their bite even when baked!
Ingredients
- Apple – 1 medium size Honeycrisp apple. Or any apple you like to bake with!
- Pure Maple Syrup – Be sure it is pure maple syrup and not pancake syrup.
- Unsalted Butter – The butter makes the caramel apples rich and creamy.
- Ground Cinnamon – We use cinnamon in both the apples mix an cookie mix.
- Vanilla Extract – A little extra layer of flavor.
- Oat Flour – You can purchase oat flour or make your own using rolled oats!
- Almond Flour – I like to use blanched almond flour because it is without the almond skins and it is ground finer.
- Rolled Oats – Rolled oats are my preference for their size and texture.
- Organic Cane Sugar – I like to use cane sugar because it is not as refined as regular white sugar.
- Baking Soda – The baking soda will give the cookie texture and a little lift.
- Salt – Salt is key for balancing and highlighting flavors!
- Egg Yolk – Only 1 egg yolk to help with binding, but also add a richness to the cookie.
Helpful Tips
- Use an apple you like to bake with – Just because I like Honeycrisp apples, doesn’t mean you do! My only recommendation is to choose an apple that is a little more firm, so you don’t end up with applesauce!
- Peel the apple, if you wish – I did not peel my apple because I like the extra texture. You certainly can peel yours.
- Chop the apple into small cubes – This is a small batch cookie recipe, therefore we don’t want huge chunks of apples! I recommend 1/4 inch cubes (or so).
- Don’t overcook the caramel apples – If you leave the caramel apples on the stove too long, eventually the apples will cook too soft and the caramel will lose its sauce consistency.
- Stir the dry ingredients together first – I like to recommend this because it ensures even distribution and mixing of all the ingredients!
- Lightly grease the cast iron – Since we aren’t taking the cookie out of the skillet to enjoy it, we don’t need to go overboard on the greasing!
- Don’t fret about the cookie dough – You will ask yourself is there enough liquid in this dough? And the answer is yes. Once you add the caramel apples with all their sauce, that will moisten the dough perfectly!
- Let the cookie cool completely – Or nearly completely! I find gluten free bakes taste better when cooled.
Recipe FAQ
You can, but then it wouldn’t be a skillet cookie! You can try a small casserole dish or a 6-inch cake pan to make the skillet cookie into cookie bars.
Yes! I would use a medium size cookie scoop and they probably only need to be baked about 10 to 12 minutes. But you will want to keep an eye on the bake time.
Any leftover cookie can stay in the skillet. Just cover with foil or plastic wrap and keep at room temperature.
Caramel Apple Oatmeal Mini Skillet Cookie
INGREDIENTS
Caramel Apples
- 1/2 cup apples, chopped (about 1 medium apple; I use a Honeycrisp apple)
- 2 tablespoons pure maple syrup (or any sweetener)
- 1 tablespoon unsalted butter
- 1/4 teaspoon ground cinnamon
- 1/2 teaspoon vanilla extract
Glute Free Oatmeal Skillet Cookie
- 1/4 cup gluten free oat flour (or all-purpose flour)
- 1/4 cup blanched almond flour (or all-purpose flour)
- 1/4 cup rolled oats
- 1/4 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 teaspoon ground cinnamon (more or less to taste)
- 5 tablespoons organic cane sugar (or granulated sugar)
- 1 large egg yolk
- prepared caramel apples
INSTRUCTIONS
Caramel Apples
- Chop the apple into small cubes (about 1/4 inch). Peeling the apples is optional.
- In a small skillet, add the maple syrup and butter. Heat the syrup over medium heat until the butter melts and the syrup starts to bubble and thicken. About 3 minutes.2 tablespoons pure maple syrup, 1 tablespoon unsalted butter
- Add the apple cubes and cinnamon. Cook the apples over medium heat until the juices are released and cooked out, and the syrup turns back into a caramel. About 5 to 7 minutes. Stir in the vanilla extract at the end. Note – Once the apples are added to the caramel, the juices from the apples will thin it out. You want to cook the apples until the caramel turns back into caramel.1/2 cup apples, chopped, 1/4 teaspoon ground cinnamon, 1/2 teaspoon vanilla extract
- Transfer the caramel apples to a small bowl or dish, and let cool at room temperature while you prepare the skillet cookie.
Gluten Free Oatmeal Skillet Cookie
- Preheat the oven to 350F degrees and adjust the oven rack to the middle position. Lightly grease a 6-inch cast iron skillet.
- In a medium mixing bowl, stir together the oat flour, almond flour, oats, baking soda, salt, cinnamon, and sugar. Note – I use a fork to stir since all the ingredients are going into one bowl.1/4 cup gluten free oat flour, 1/4 cup blanched almond flour, 1/4 cup rolled oats, 1/4 teaspoon baking soda, 1/4 teaspoon salt, 1/2 teaspoon ground cinnamon, 5 tablespoons organic cane sugar
- Add the egg yolk to the dry ingredients and stir until thoroughly incorporated. Add the cooled caramel apples – along with all the caramel sauce! – and stir until the dry ingredients are moistened and a cookie dough forms. Note – It will seem like there isn't enough wet ingredients to make a dough. Rest assured, the caramel apples will moisten the dry ingredients sufficiently!1 large egg yolk, prepared caramel apples
- Spoon the cookie dough into the prepared skillet. Press the cookie dough evenly into the skillet, all the way to the edges. Set the skillet on the small baking sheet to make getting the cookie in and out of the oven easier. Bake the cookies for 23 to 25 minutes, or until the top and edges are golden brown. Note – For a chewier cookie, check it at 23 minutes. For a crispier cookie, bake for 26 minutes and check it.
RECIPE NOTES
- Serving Size – This is a mini skillet cookie that will yield enough for 2 to 4 people – depending on your serving size. The recipe is easily doubled in an 8 or 9-inch skillet.
- Mini Cast Iron Skillet – The skillet I use and have linked in the recipe actually measures about 6.5 inches.
- Apples – I recommend a firm variety apple like Honeycrisp (which is what I typically use), Granny Smith, Pink Lady, or Fuji.
- Gluten Free Oat Flour – Oat flour is naturally gluten free, though it can be subject to cross-contamination in processing. Look for gluten free labeled flour.
- Make Your Own Oat Flour – You can make your own oat flour by grinding rolled oats into flour in a blender or food processor. The flavor is wonderful!
- Ingredient Substitutions – You can try to swap the GF flours for regular all-purpose flour if you don’t need a GF cookie.
