Gather your ingredients, making sure your butter is softened, and your eggs are room temperature.

Preheat the oven to 350 degrees F (175 degrees C).

Beat butter, white sugar, and brown sugar with an electric mixer in a large bowl until smooth.

Beat in eggs, one at a time, then stir in vanilla.

Dissolve baking soda in hot water. Add to batter along with salt.

Stir in flour, chocolate chips, and walnuts.

Drop spoonfuls of dough 2 inches apart onto ungreased baking sheets.

Bake in the preheated oven until edges are nicely browned, about 10 minutes.

Cool on the baking sheets briefly before removing to a wire rack to cool completely.

Store in an airtight container or serve immediately and enjoy!
