If you’re craving thick, chewy Oatmeal Butterscotch Cookies (aka Scotchies) with lightly golden edges and soft, cozy centers, this is the recipe to bake. They’re buttery, brown-sugary, packed with hearty oats, and loaded with butterscotch chips that melt into sweet little pockets in every bite.
If you love classic cookie comfort, you’ll also want to peek at my Oatmeal Raisin Cookies, Toll House Cookies, Chocolate Crinkle Cookies, and Almond Joy Cookies— because one cookie recipe always turns into “just one more,” right? 😉
These cookies work so well because cool-soft butter creams up fluffy for structure, the extra egg yolk gives you that chewy set, the cornstarch keeps the texture tender, and a simple 1-hour chill helps them bake tall instead of spreading flat.
Now grab your cookie scoop — your house is about to smell like pure, cozy happiness. 💛
✨ Before You Start
✨ Make sure your butter is cool-soft, not greasy. If it’s too warm, the cookies will spread before they set.
✨ Use old-fashioned oats, not quick oats — they give these cookies their signature hearty chew.
✨ Don’t skip the 1-hour chill. It firms up the dough just enough to help the cookies bake thick.
✨ Scoop the dough into tall mounds, not flattened discs. Height going into the oven = thickness coming out.
Oatmeal Butterscotch Cookies Ingredients + Key Notes
This is just a quick glance at what you’ll need. For exact measurements and the full ingredient list, head down to the recipe card below.
- All-Purpose Flour – Provides structure while still keeping the cookies tender.
- Cornstarch – Helps soften the crumb and encourages a thicker, chewier cookie.
- Baking Soda – Gives just enough lift so the cookies don’t bake up dense.
- Fine Salt – Balances the sweetness of the butterscotch chips.
- Ground Cinnamon (optional) – Adds a warm, cozy note that pairs beautifully with oats and butterscotch.
- Unsalted Butter – Softened to a cool, pliable texture for proper creaming and controlled spread.
- Brown Sugar + Granulated Sugar – Brown sugar brings moisture and chew; granulated sugar adds balance and lightness.
- Egg + Egg Yolk – The extra yolk boosts richness and creates that thick, chewy interior.
- Vanilla Extract – Rounds out the sweetness and enhances the butterscotch flavor.
- Old-Fashioned Oats – Essential for classic Scotchies texture.
- Butterscotch Chips – The star of the show, melting into sweet pockets throughout the cookies.
- Toasted Pecans (optional) – Add crunch and a subtle nutty contrast if you like a little texture.
⭐ Pro Tips
⭐ Butter temperature matters
Softened butter should feel cool to the touch and hold its shape when pressed. If it’s shiny or greasy, your cookies will spread more than you want.
⭐ Chill for thickness
That short chill isn’t about flavor — it’s about structure. Cold dough hits the oven and sets before the butter fully melts, keeping the cookies tall and chewy.
⭐ Scoop tall, not wide
Resist the urge to flatten the dough. Tall mounds bake up thicker with soft centers.
⭐ Pull them early
The centers should look just set, not fully firm. They’ll continue cooking as they cool on the baking sheet.
🥣 How to Make Oatmeal Butterscotch Cookies
Start by whisking the dry ingredients so everything bakes evenly. Cream the softened butter with both sugars until fluffy — this step builds structure and helps the cookies stay thick. Mix in the egg, egg yolk, and vanilla just until smooth.
Add the dry ingredients on low speed and stop mixing while the dough still looks soft and cohesive. Fold in the oats, butterscotch chips, and pecans if using. Chill the dough for one hour so it firms up enough to hold its shape in the oven.
Scoop tall mounds of dough onto parchment-lined baking sheets and bake until the edges are lightly golden and the centers look just set. Let the cookies cool on the pan for a few minutes — this gentle carryover heat finishes the centers without drying them out.
Storing + Reheating + Freezing + Make-Ahead Tips
Storing
- Store baked cookies in an airtight container at room temperature for up to 4 days. They stay soft and chewy, especially if you add a slice of bread to the container.
Reheating
- Warm cookies briefly in the microwave for 8–10 seconds to revive that fresh-from-the-oven softness.
Freezing
- Freeze baked cookies or unbaked dough balls for up to 3 months. Bake dough balls straight from frozen, adding 1–2 minutes to the bake time.
Make-Ahead
- The dough can be made up to 48 hours ahead and kept covered in the refrigerator until ready to bake.

✦Frequently Asked Questions
✦ Why do I need to chill the dough?
Chilling firms up the butter and hydrates the flour, which helps the cookies bake thick instead of spreading flat.
✦ Can I skip the pecans?
Absolutely. The cookies are delicious without nuts, or you can swap in walnuts if you prefer.
✦ Can I make these smaller?
Yes — just reduce the bake time by a minute or two and watch the edges closely.

Oatmeal Butterscotch Cookies
Ingredients
- 1 3/4 cups all-purpose flour
- 1 tablespoon cornstarch
- 1 teaspoon baking soda
- 1 teaspoon fine sea salt or about 1 teaspoon Morton kosher
- 1 1/2 teaspoons ground cinnamon
- 1 cup unsalted butter, softened
- 1 cup light brown sugar, packed
- 1/2 cup granulated sugar
- 1 large egg, room temperature
- 1 large egg yolk, room temperature
- 2 teaspoons vanilla extract
- 2 1/2 cups old-fashioned rolled oats
- 1 3/4 cups butterscotch chips
- 1/2 cup toasted pecans, chopped
Instructions
- Prep. Line baking sheets with parchment.
- Mix the dry ingredients. In a medium bowl, whisk together flour (1 3/4 cups), cornstarch (1 tablespoon), baking soda (1 teaspoon), salt (1 teaspoon), and cinnamon (1 1/2 teaspoons).
- Cream butter + sugars. In a large bowl, beat softened butter (1 cup) with brown sugar (1 cup) and granulated sugar (1/2 cup) for 2 minutes, until fluffy and well combined.
- Add eggs + vanilla. Beat in the egg (1), then the egg yolk (1), then the vanilla (2 teaspoons), mixing just until smooth.
- Add dry ingredients. Mix in the dry ingredients on low speed just until combined—don’t overmix.
- Stir in oats + chips. Fold in the oats (2 1/2 cups), 1 cup butterscotch chips, and pecans (1/2 cup) until evenly distributed.
- Scoop + shape dough. Scoop 1/4 cup balls of dough. Roll them into balls to compress the dough into a cohesive shape. Shape the balls of dough into a tall cylander shape ~keep them tall (don’t flatten). Arrange all the dough mounds on one cookie sheet.Press the remaining butterscotch chips into the dough.Cover the cookie sheet with plastic wrap and refrigerate the dough balls for 1 hour.Before Baking, preheat oven to 350 degrees.
- Bake + set properly. Place the dough mounds on the baking sheet at least 2 inches apart (about 6 cookies per sheet).Bake 11–14 minutes, until the edges are lightly golden and the cookies look set around the edges — centers that still look a little underdone (a bit wet). Let the cookies cool on the baking sheet for 10 minutes before moving; they’ll finish setting as they cool.
