- All-Purpose Flour: This provides structure; be sure to measure accurately using a spoon-and-level method.
- Baking Soda: Essential for that perfect rise—don’t skip this ingredient!

Let’s Make it together
Preheat Your Oven: Begin by preheating your oven to 350°F (175°C). Line two baking sheets with parchment paper to prevent sticking.
Cream Your Butter and Sugars Together: In a large mixing bowl, beat together softened butter, brown sugar, and granulated sugar until light and fluffy. This should take about 3 minutes of vigorous mixing.
Add Eggs and Vanilla Extract: Crack in those large eggs one at a time while mixing well after each addition. Stir in your vanilla extract until everything is smoothly combined.
Mix Dry Ingredients Separately: In another bowl, whisk together flour, baking soda, oats, and salt until well blended. This ensures even distribution of baking soda throughout your dough.
Combine Wet and Dry Mixtures Together: Gradually fold your dry ingredients into the wet mixture until just combined—avoid overmixing here to keep those cookies tender!
Add Chocolate Chips and M&Ms**: Gently fold in chocolate chips along with M&Ms or any other add-ins you fancy. Aim for an even distribution so every bite is loaded with flavor!
Now you’re ready to scoop those beauties onto your prepared baking sheets!
**Scoop Onto Baking Sheets**: Use a tablespoon or cookie scoop to drop generous mounds of dough onto the lined sheets—about two inches apart works perfectly so they won’t merge during baking.
**Bake Until Golden Brown**: Place those sheets in your preheated oven and bake for about 10-12 minutes until edges are golden but centers remain slightly soft. They’ll firm up as they cool.
**Cool Before Enjoying**: Allow them to cool on the baking sheets for about 5 minutes before transferring them to wire racks. Trust me; you want them warm but not molten lava hot!
