Ingredients
- 1/2 cup unsalted butter, softened
- 1 cup creamy peanut butter
- 1 cup packed light brown sugar
- 1/2 cup granulated sugar
- 3 large eggs
- 1 teaspoon vanilla extract
- 2 teaspoons baking soda
- 1/2 teaspoon salt
- 4 1/2 cups old-fashioned rolled oats
- 1 cup semisweet chocolate chips
- 1 cup M&M's candies
Instructions
- Preheat oven to 350°F (175°C). Line two baking sheets with parchment paper.
- In a large bowl, beat butter, peanut butter, brown sugar, and granulated sugar until creamy, about 2 minutes.
- Add eggs one at a time, beating well after each addition. Beat in vanilla extract.
- In a separate bowl, whisk together baking soda, salt, and oats. Gradually add to the wet mixture, mixing until just combined.
- Fold in chocolate chips and M&M's.
- Drop dough by rounded tablespoons (about 1.5 tablespoons each) onto prepared baking sheets, spacing 2 inches apart.
- Bake for 10-12 minutes, until edges are golden but centers are still soft.
- Let cookies cool on baking sheets for 5 minutes, then transfer to wire racks to cool completely.
Tips
- For softer cookies, slightly underbake and let cool on the sheet.
- Store in an airtight container at room temperature for up to 5 days.
- These cookies freeze well for up to 3 months.
