Soft and Chewy Oatmeal Butterscotch Cookies
These oatmeal butterscotch cookies have crisp edges and a dense, tender center loaded with butterscotch chips. The dough comes together fast in one bowl, no mixer needed, and the melted butter keeps them chewy for days.
They spread just enough in the oven, with a deep brown sugar flavor and pockets of sweet, buttery chips in every bite. No chilling required, but a brief rest in the fridge will give you a slightly thicker cookie if that’s your style.
Why These Oatmeal Butterscotch Cookies Work
The cookie gets its chew from melted butter, an extra egg yolk, and a larger amount of brown sugar. That combination keeps the centers soft while the outsides turn golden.
A small pinch of cinnamon deepens the caramel notes without shouting “spice cookie.” The butterscotch chips melt into gooey little pools that set up just enough when the cookies cool.
I can throw a batch together on a Tuesday and they stay soft in the container all week. The recipe is simple enough to memorize after two bakes.
Ingredients
- 1 cup unsalted butter, melted and cooled: using melted butter makes the cookies extra chewy; cool it so it doesn’t cook the egg.
- 1 cup packed dark brown sugar: dark brown sugar adds a deeper molasses flavor, but light brown works too.
- ½ cup granulated sugar: gives the edges a little crispness.
- 1 large egg: at room temperature if you remember, cold is fine here.
- 1 large egg yolk: adds richness and chew.
- 2 teaspoons vanilla extract: rounds out the butterscotch.
- 1 ½ cups all-purpose flour: spooned and leveled so the cookies aren’t dry.
- 1 teaspoon baking soda: gives them a gentle lift.
- ½ teaspoon fine sea salt: cuts the sweetness.
- ½ teaspoon ground cinnamon: a small amount that warms the flavor without taking over.
- 3 cups old-fashioned rolled oats: nothing beats old-fashioned oats for texture.
- 1 ¾ cups butterscotch chips: feel free to go generous, they’ll melt more than chocolate chips.
Variations / Substitutions
- Chocolate chips instead of butterscotch: swap 1:1 with semi-sweet or dark chocolate chips for a more classic chocolate chip oatmeal cookie.
- Add toasted pecans: fold in ½ cup chopped toasted pecans with the chips for a nutty crunch.
- Use a gluten-free flour blend: replace the all-purpose flour with a cup-for-cup gluten-free blend and confirm your oats are certified gluten-free.
- Drizzle with salted caramel: after baking, drizzle a little warm salted caramel sauce over the cooled cookies for extra indulgence.
- A great side-by-side pair is Soft Oatmeal Raisin Cookies if you want a spiced, fruitier version.
How to Make Soft and Chewy Oatmeal Butterscotch Cookies
Step 1: Mix the Wet Ingredients
In a large bowl, whisk together the 1 cup melted butter, 1 cup brown sugar, and ½ cup granulated sugar until smooth and no streaks of butter remain. Whisk in the 1 egg, 1 egg yolk, and 2 teaspoons vanilla until the mixture looks glossy and uniform.
The batter will be thick and dark from the brown sugar. At this point it should feel a little warm if you touch the outside of the bowl, but not hot.
Step 2: Stir in the Dry Ingredients
Sprinkle the 1 ½ cups flour, 1 teaspoon baking soda, ½ teaspoon salt, and ½ teaspoon cinnamon over the wet mixture. Stir with a wooden spoon or a spatula just until no white streaks of flour remain, scraping the bottom of the bowl once.
The dough will be soft and a little sticky. Stop mixing as soon as the flour disappears so the cookies stay tender.
Step 3: Fold in the Oats and Chips
Add the 3 cups rolled oats and 1 ¾ cups butterscotch chips to the bowl. Fold everything together until the oats and chips are evenly dispersed, using a spatula to bring the bottom up and over.
You’ll end up with a heavy, chunky dough that smells deeply of brown sugar and butter. Don’t worry if it looks dry at first; the oats will hydrate more as the dough sits.
Step 4: Scoop and Bake
Preheat the oven to 350°F (180°C) and line two baking sheets with parchment paper. Scoop the dough by heaping tablespoonfuls (about 2 tablespoons each) and place them 2 inches apart on the sheets. Bake for 10 to 12 minutes, rotating the pans top to bottom and front to back halfway through.
The cookies are ready when the edges are golden brown but the centers still look a touch pale and underbaked. They’ll continue baking on the hot sheet once you pull them out. Going slightly under keeps the middles soft.
Step 5: Cool and Serve
Let the cookies sit on the baking sheet for 5 minutes so they can set, then transfer them to a wire rack to finish cooling. They’re easiest to move with a thin spatula while still warm.
Serve them warm when the butterscotch chips are still melty, or at room temperature once the chips firm up. A glass of cold milk alongside never hurts.
Tips for Soft, Chewy Oatmeal Butterscotch Cookies
- Weigh your flour if you have a scale: 1 ½ cups all-purpose flour should weigh 180 grams. Too much flour will make the cookies cakey.
- An extra egg yolk really helps the chew, so don’t skip it or use just two whole eggs.
- If your kitchen is warm, pop the dough in the fridge for 30 minutes before baking to prevent excessive spreading.
- Press a few extra butterscotch chips onto the tops of the dough balls right before baking so they’re visible after they spread.
- Underbaking by a minute is safer than overbaking. The cookies will look softer than you expect but set up beautifully.
Bake times by cookie size:
| Cookie Size (scoop) | Bake Time |
|---|---|
| 1 tablespoon | 8-10 mins |
| 1 ½ tablespoons | 9-11 mins |
| 2 tablespoons | 10-12 mins |
| 3 tablespoons | 12-14 mins |
Storing Leftover Cookies
- Room temperature: Keep cooled cookies in an airtight container with a slice of plain bread for up to 5 days. The bread adds moisture and keeps them soft.
- Freezer: Freeze baked cookies in a zip-top bag for up to 3 months. Thaw at room temperature or warm briefly in the microwave.
- Freezer dough: Scoop dough balls onto a parchment-lined sheet, freeze until solid, then transfer to a bag. Bake from frozen, adding 1 to 2 minutes to the time.
Frequently Asked Questions
Can I use quick oats instead of old-fashioned rolled oats?
Yes, but the texture will be finer and less chewy. Rolled oats give these cookies the best bite.
My cookies spread into flat puddles. What went wrong?
Your butter was probably too warm when you mixed the dough, or the baking sheet was hot between batches. Cool the butter fully and chill the dough for 20 minutes before scooping.
Can I make these cookies dairy-free?
You can. Use a solid plant-based butter stick that melts well, and check that your butterscotch chips are dairy-free, or swap them out for vegan chocolate chips.
How do I keep the cookies soft after day one?
Store them in an airtight container with a slice of bread or an apple piece. The cookies absorb the extra moisture and stay tender.
