Difficulty Level: Easy
Cuisine: American
Ingredients
- 1 cup (226 g) unsalted butter, softened
- 1 cup granulated sugar
- ½ cup brown sugar, packed
- 2 large eggs
- 2 teaspoons vanilla extract
- 1¾ cups all-purpose flour
- ½ cup unsweetened cocoa powder
- 1 teaspoon baking soda
- ½ teaspoon baking powder
- ½ teaspoon salt
- 2 cups old-fashioned rolled oats
- 1½ cups semi-sweet chocolate chips
- ½ cup dark chocolate chunks (optional)
- ½ cup chopped walnuts or pecans (optional)
Instructions
Step 1: Prepare the Oven
Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone baking mats.
Step 2: Mix the Wet Ingredients
In a large mixing bowl, beat the softened butter, granulated sugar, and brown sugar until light and fluffy, about 2–3 minutes. Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
Step 3: Combine the Dry Ingredients
In a separate bowl, whisk together the flour, cocoa powder, baking soda, baking powder, and salt until evenly combined.
Step 4: Make the Cookie Dough
Gradually add the dry ingredients to the butter mixture, mixing until just combined. Fold in the rolled oats, chocolate chips, chocolate chunks, and nuts if using. Do not overmix.
Step 5: Scoop the Dough
Using a cookie scoop or tablespoon, place rounded portions of dough onto the prepared baking sheets, leaving about 2 inches between each cookie.
Step 6: Bake
Bake for 10–12 minutes. The edges should be set while the centers remain slightly soft. Avoid overbaking, as the cookies will continue to firm up while cooling.
Step 7: Cool
Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
Tips for Perfect Cookies
- Use room-temperature butter for a smooth cookie dough.
- Measure the flour correctly by spooning it into the measuring cup and leveling it off.
- Chill the dough for 20–30 minutes if you prefer thicker cookies.
- Use high-quality cocoa powder and chocolate for the richest flavor.
- Sprinkle a tiny pinch of flaky sea salt on top before baking for a bakery-style finish.
Storage
Store the cookies in an airtight container at room temperature for up to 5 days. They can also be refrigerated for up to one week.
For longer storage, freeze baked cookies for up to 3 months. Thaw at room temperature before serving.
Variations
- Add dried cherries or cranberries for a fruity twist.
- Replace semi-sweet chocolate chips with white chocolate chips.
- Stir in shredded coconut for extra texture.
- Use gluten-free rolled oats and gluten-free flour to make a gluten-friendly version.
Serving Suggestions
Serve these cookies warm with a glass of cold milk, hot coffee, or hot chocolate. They also make a delicious ice cream sandwich when filled with vanilla or chocolate ice cream.
