STEP 1: PREHEAT THE OVEN

Begin by preheating your oven to 350°F (175°C). This ensures even baking and helps the cookies rise perfectly. Proper preheating is crucial for achieving the desired texture.

STEP 2: MAKE THE COOKIE DOUGH

In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until the mixture is light and fluffy, about 3-4 minutes. This process incorporates air into the mixture, which contributes to a tender cookie.

Add the eggs, one at a time, mixing well after each addition. Stir in the vanilla extract until fully combined. The combination of these ingredients will create a rich and flavorful dough.

In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add the dry ingredients to the wet mixture, mixing until just combined. Be careful not to overmix, as this can lead to tough cookies. The dough should be soft but not sticky.

STEP 3: ADD THE MIX-INS

Gently fold in the chocolate chips and chopped pistachios. Ensure that the mix-ins are evenly distributed throughout the cookie dough for a balanced flavor in every bite. You can use a spatula or wooden spoon to incorporate them gently.

STEP 4: FORM THE COOKIES

Using a cookie scoop or tablespoon, portion out the cookie dough onto a baking sheet lined with parchment paper. Space the dough balls about 2 inches apart, as they will spread during baking. If you like, you can roll the dough into balls for a more uniform shape.

STEP 5: BAKE THE COOKIES

Place the baking sheet in the preheated oven and bake for about 10-12 minutes, or until the edges are set and the centers appear slightly soft. The cookies will continue to cook as they cool on the baking sheet, so be careful not to overbake them.

STEP 6: COOL AND ENJOY

Once baked, remove the cookies from the oven and let them cool on the baking sheet for about 5 minutes before transferring them to a wire rack to cool completely. This allows the cookies to firm up without becoming too crumbly.
