Directions to follow
- Preheat your oven to 350°F (175°C). Line a rimmed baking sheet with parchment paper for easy cleanup.
- In a large mixing bowl, cream together the softened butter, brown sugar, and white sugar until light and fluffy—this usually takes about 2-3 minutes.
- Lightly beat the eggs and mix them in, along with the vanilla extract, until thoroughly incorporated.
- In a separate bowl, whisk together the flour, baking powder, baking soda, and salt.
- Gradually add the dry ingredients to the wet mixture, combining until no streaks remain. Avoid over-mixing, which can make the bars tough.
- Gently fold in the chocolate chips and 1 cup of M&Ms until evenly distributed throughout the dough.
- Spread the batter evenly onto the prepared baking sheet, ensuring it reaches the corners. Sprinkle the remaining M&Ms on top for a colorful finish.
- Bake for 20-22 minutes, or until the edges are lightly browned and a toothpick inserted into the center comes out clean.
- Allow the bars to cool in the pan for at least 20 minutes before cutting into 36 squares.

How to store
To keep your M&M Cookie Bars fresh, store them in an airtight container at room temperature for up to a week.

When you’re ready to enjoy, thaw them overnight in the refrigerator, and they will taste as delicious as the day they were baked.
Helpful cooking tips
For the best texture, be sure your butter is at room temperature before creaming it with the sugars. This step is crucial for incorporating air into your mixture, resulting in soft, chewy bars. If you find yourself short on time, you can also use a hand mixer to speed up the creaming process. For a fun twist, try adding chopped nuts or dried fruit for additional flavor and texture.
