Ingredients

- 1 cup all-purpose flour
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1/2 cup unsalted butter, softened
- 1/2 cup granulated sugar
- 1/2 cup brown sugar, packed
- 1 large egg
- 1 teaspoon vanilla extract
- 1 1/2 cups old-fashioned oats
- 1/2 cup raisins or chocolate chips (optional)
Step-by-Step Instructions
Step 1: Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper.
Step 2: In a large mixing bowl, combine the softened butter, granulated sugar, and brown sugar. Use a wooden spoon or spatula to mix until well combined and creamy. No electric mixer needed!
Step 3: Add the egg and vanilla extract to the butter-sugar mixture. Stir vigorously until the egg is fully incorporated and the mixture is smooth.
Step 4: Sprinkle the flour, baking soda, and salt over the wet ingredients. Gently fold everything together until just combined – be careful not to overmix.
Step 5: Stir in the oats and any optional add-ins like raisins or chocolate chips. The dough will be thick and slightly sticky.
Step 6: Using a tablespoon or cookie scoop, drop rounded balls of dough onto your prepared baking sheets, spacing them about 2 inches apart.
Step 7: Bake for 10-12 minutes, or until the edges are golden brown and the centers look set. The cookies will continue to firm up as they cool.
Step 8: Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
Expert Tips for Perfect Cookies
Butter Temperature Matters: Make sure your butter is properly softened (room temperature) but not melted. This ensures the perfect cookie texture without needing a mixer.
Don’t Overbake: The cookies might look slightly underdone when you take them out of the oven, but they’ll continue cooking on the hot baking sheet. This is the secret to soft, chewy centers!
Customize Your Cookies: Feel free to add 1/2 teaspoon of cinnamon for warm spice flavor, or swap the raisins for dried cranberries, chopped nuts, or white chocolate chips. For more cookie inspiration, check out our Ultimate Oatmeal Cookies Recipe.
Storage Tips: Store cooled cookies in an airtight container at room temperature for up to 5 days. They also freeze beautifully for up to 3 months.
