Creating Cookie Monster Cookies can be straightforward if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper.
2. Mix Dry Ingredients: In a bowl, whisk together the flour, baking soda, and salt. Set aside.
3. Cream Butter and Sugars: In a large mixing bowl, cream the softened butter, brown sugar, and granulated sugar until light and fluffy.
4. Add Eggs and Vanilla: Beat in the eggs one at a time, then stir in the vanilla extract until well combined.
5. Combine Mixtures: Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
6. Add Blue Color: If using blue food coloring, add it now until desired color is reached. If using blue candy melts, melt them and fold them into the batter.
7. Fold in Chocolate Chips: Gently fold in the semisweet chocolate chips and M&M’s if desired.
8. Scoop Cookies: Using a cookie scoop or tablespoon, drop dough onto the prepared baking sheets, spacing them about 2 inches apart.
9. Bake: Bake in the preheated oven for 10-12 minutes or until the edges are lightly golden, and the centers look slightly underbaked.
10. Cool: Remove from the oven and allow the cookies to cool on the baking sheets for 5 minutes before transferring them to wire racks to cool completely.

These steps will guide you in creating these incredible cookies effortlessly.
