Homemade Chewy Oatmeal Butterscotch Cookies Recipe

Key Ingredients

The complete recipe appears below in the recipe card. Here are the key ingredients and why they matter:

• Unsalted butter (softened) – Adds richness, moisture, and helps create golden, slightly crisp edges. If you use salted butter, reduce or omit the added salt in the recipe.
• Granulated sugar – Contributes sweetness and helps cookies spread properly.
• Light brown sugar – Provides deeper caramel notes and chewiness because of its molasses content.
• Vanilla extract – Rounds and enhances the overall flavor.
• All-purpose flour – The structural base of the dough. You can use bleached or unbleached flour.
• Baking soda – Helps the cookies spread and develop a beautiful golden color.
• Old-fashioned oats – Provide hearty texture and chew. Use old-fashioned oats rather than quick oats for the best bite.
• Butterscotch chips – The star ingredient that creates pockets of buttery, caramel-like flavor. If you don’t have butterscotch chips, you can substitute caramel chips, chocolate chips, or chopped nuts, though the flavor will differ.

Make It

This recipe can be mixed with a stand mixer or a hand mixer. The method below produces cookies that are thin with chewy centers and crisp edges.

1. Preheat the oven to 350°F (175°C). Line three large cookie sheets with parchment paper.
2. Spread 1 1/4 cups old-fashioned oats in a single layer on one pan and bake for 5 minutes. Remove and let cool. Process 4 tablespoons of the toasted oats in a food processor or blender until they form a fine powder; reserve the rest of the toasted oats whole.
3. In a large bowl or the bowl of a stand mixer, beat 1 cup (226 g) softened unsalted butter with 1/2 cup granulated sugar and 3/4 cup light brown sugar until the mixture is light and fluffy, about 4–5 minutes. Scrape the sides and bottom of the bowl halfway through.
4. Add 1 large room-temperature egg and 1 teaspoon vanilla extract and mix just until combined.
5. In a separate bowl, whisk together 1/2 cup all-purpose flour, 1 teaspoon baking soda, 1 teaspoon kosher salt, 1 teaspoon sea salt flakes, the reserved toasted oats and the oat powder. Stir to combine. Toss 1 cup (180 g) butterscotch chips in a small amount of the flour-oat mixture to lightly coat them—this helps prevent sinking.
6. With the mixer on low, add the dry mixture to the butter mixture in two additions, mixing until just combined. Finish mixing by hand with a rubber spatula to avoid overworking the dough. Fold in the butterscotch chips evenly.
7. Reduce oven temperature to 340°F (160°C). Using a medium cookie scoop (about 1 1/2 tablespoons), place four scoops of dough per sheet, spacing cookies 2–3 inches apart.
8. Bake on the middle rack for 8 minutes. Remove the pan and, while the cookies are warm and still soft, use a large round cookie cutter or a wide spatula to gently twirl and round each cookie so they bake into a uniform, circular shape. Return the pan to the oven and bake an additional 4–6 minutes until edges are golden and centers are set.
9. Remove from the oven and twirl the cookies again if desired to refine their shape. Allow cookies to cool on the pan for a few minutes before transferring to a wire rack to cool completely.
10. Repeat with remaining dough. For thinner, more spread cookies, lower the oven temperature to 320°F; for thicker cookies, increase the flour by up to 1 cup.

Tips

• Bring ingredients to room temperature for even mixing and better texture.
• The original dough has a high butter-to-flour ratio, which causes considerable spreading—this yields thin, crisp-edged cookies. For thicker cookies, add more all-purpose flour (up to 1 to 1 1/2 cups extra total).
• Use a 1 1/2 tablespoon cookie scoop for consistent cookie size and bake times.
• Add a pinch of ground cinnamon or nutmeg to the dry mix for a warm spice note.
• Do not overcrowd the baking sheet; leave space for the cookies to spread evenly.
• Allow cookies to set on the pan briefly before transferring to a wire rack to prevent breakage.

Storing and Freezing

Store baked and cooled cookies in an airtight container at room temperature for up to one week. To freeze, place cooled cookies in an airtight container or heavy-duty freezer bag and freeze for up to eight weeks. Thaw at room temperature before serving.
