📖 Instructions

1. **Get Started:** Preheat your oven to 375°F (190°C). Line two baking sheets with parchment paper. This prevents sticking and makes cleanup a breeze.
2. **Cream Together:** In a large bowl, cream together 1 cup (2 sticks) of softened unsalted butter and 3/4 cup of packed brown sugar and 1/4 cup of granulated sugar until light and fluffy. This step is crucial for achieving that melt-in-your-mouth texture. Don't rush it!
3. **Incorporate the Egg and Vanilla:** Beat in 1 large egg and 1 teaspoon of vanilla extract until well combined. Scrape down the sides of the bowl to ensure everything mixes evenly.
4. **Dry Ingredients Unite:** In a separate bowl, whisk together 2 1/4 cups of all-purpose flour, 1 teaspoon of baking soda, and 1/2 teaspoon of salt. Make sure there aren't any clumps of baking soda. A uniform mixture is key!
5. **Combine Wet and Dry:** Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix; overmixing develops the gluten in the flour, resulting in tough cookies.
6. **The Cheese Revelation:** Crumble 4 ounces of good-quality blue cheese (such as Roquefort or Gorgonzola) into the dough. Gently fold it in until it's evenly distributed. Don't be afraid to get your hands in there!
7. **Nutty and Chocolate Additions:** Add 1 cup of chopped walnuts and 1 cup of chocolate chips (dark or semi-sweet, depending on your preference) to the dough. Fold them in until they're evenly dispersed. These additions bring the comforting sweetness and crunch, complementing the cheese beautifully.
8. **Portion the Dough:** Drop by rounded tablespoons onto the prepared baking sheets, leaving about 2 inches between each cookie. Slightly flatten the tops with your fingers.
9. **Bake to Perfection:** Bake for 10-12 minutes, or until the edges are golden brown and the centers are set. Keep a close eye on them; oven temperatures can vary.
10. **Cooling is Key:** Let the cookies cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely. This prevents them from breaking apart.
11. **Indulge (or Share!):** Serve these sophisticated cookies with a glass of milk, a cup of coffee, or even a glass of port wine for an extra-special treat. Enjoy the delightful blend of flavors!
