Ingredients

- Butter: I like using salted butter. If using unsalted butter, add 1/8 teaspoon of salt to the dry ingredients.
- Sugar: A mix of granulated and brown sugar adds sweetness. Granulated sugar provides structure, while brown sugar adds moisture and a caramel-like flavor.
- Egg Yolk: One egg yolk adds richness and helps bind the dough. Save the egg white for Meringue Cookies, mini Texas Sheet Cake, or Flourless Chocolate Cookies.
- Vanilla and Ground Cinnamon: These add warmth and enhance the butterscotch flavor.
- Flour: All-purpose flour gives the cookie structure. A gluten-free 1:1 flour blend can be used if needed.
- Baking Soda: Helps the cookie rise slightly, giving it the right texture.
- Oats: Old-fashioned oats add a chewy texture and hold their shape during baking. Quick oats won’t give the same result and aren’t recommended.
- Butterscotch Chips: These add a sweet, buttery flavor. You can swap them for chocolate chips if you prefer.
Recipe Variations
Customize your oatmeal butterscotch cookie with these easy variations:
- Oatmeal Nut Cookie: Stir in 2 tablespoons of chopped walnuts or pecans for added crunch and a nutty flavor
- White Chocolate Cranberry: Replace butterscotch chips with white chocolate chips and mix in 2 tablespoons of dried cranberries for a sweet-tart balance.
- Cinnamon Raisin Oatmeal Cookie: Swap the butterscotch chips for raisins and add an extra pinch of cinnamon for a warm, spiced version.
How To Make An Oatmeal Skillet Cookie
To make this small skillet cookie, start by heating the oven to 350°F (177°C) and buttering a 6.5-inch cast iron skillet or a 5×5-inch baking dish.
In a bowl, mix melted butter with granulated and brown sugar until smooth, then stir in the egg yolk and vanilla. In a separate bowl, combine the dry ingredients, including flour, oats, baking soda, and cinnamon. Add the dry ingredients to the wet mixture and mix until combined, then gently fold in the butterscotch chips.
Press the dough into the prepared skillet and bake for 18-20 minutes, just until lightly golden—be careful not to over-bake, as the cookie will continue cooking in the hot skillet after being removed from the oven. Let it cool for at least 10 minutes before slicing.

Expert Tips
- Grease the Skillet: Butter or lightly spray the skillet or baking dish to prevent sticking and ensure easy removal.
- Measure Flour Correctly: Spoon flour into the measuring cup and level it off with a knife to avoid using too much, which can make the cookie dense.
- Don’t Overbake: The edges should be lightly golden when you take it out. The center may look slightly underdone, but it will firm up as it cools.
Serving Ideas
Take this warm skillet cookie to the next level with one of these simple toppings:
- Vanilla Ice Cream: Add a scoop while the cookie is still warm for a classic combination.
- Caramel Drizzle: A drizzle of caramel sauce enhances the butterscotch flavor.

Love the taste of this cookie. I used a 5×5 pan, and it wasnโt finished in 20 min. I took it out as the directions suggested. It was not cooked in the center. I suggest cooking it a few minutes longer in those dishes.
I used a 5×5 baking dish in my toaster oven and let it cool for 10 minutes
per the recipe and it surely was not done in the middle. The taste is great!
I’ll make it again, but try cooking it much longer ๐
I found this site searching for comments on a turkey roast. I am cooking now and will post a review later. Thanks for recipes for one or two people. Canโt wait to try some of these.
Oh my gosh this sounds amazing!! And, then I won’t have to worry about eating all the rest of a large batch.
So delicious! I love oatmeal and butterscotch together!
