Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.

In a large mixing bowl, combine the eggs, peanut butter, light brown sugar, granulated sugar, and vanilla extract. Whisk until smooth and creamy.

Gently fold in the old-fashioned oats, baking soda, and salt, creating a thick dough.

Stir in the mini M&Ms and chocolate chips until evenly distributed.

Scoop dough onto the prepared baking sheet, spacing them 2 inches apart.

Bake for 10–12 minutes until edges are set and centers are slightly gooey.

Allow to cool on the baking sheet for 5 minutes before transferring to a wire rack.
