Preheat your oven: Begin by warming your oven to 350°F (175°C). Prepare a cookie sheet by lining it with parchment paper or greasing it lightly to prevent sticking.
Mix the dry ingredients: In a medium bowl, whisk together the flour, cocoa powder, baking soda, baking powder, and salt. This ensures that everything is evenly distributed for the best texture.
Cream the butter and sugars: Using an electric mixer, cream together the softened butter, brown sugar, and granulated sugar. Beat for about 3-4 minutes until smooth and fluffy. This step is essential for creating those soft and chewy cookies!
Add the eggs and vanilla: Beat the eggs in one at a time, making sure each one is fully incorporated before adding the next. Stir in the vanilla extract for that wonderful flavor boost.
Combine the dry and wet ingredients: Gradually add the dry ingredients to the wet mixture, mixing until just combined. Over-mixing can lead to tougher cookies, so be sure to stop once everything is well incorporated.
Fold in the Hershey’s chocolate chips: Carefully fold in the chocolate chips with a spatula, ensuring they’re evenly distributed throughout the dough.
Scoop the dough: Use a spoon or cookie scoop to form rounded portions of dough and drop them onto your prepared cookie sheet. Be sure to leave about 2 inches of space between each scoop to allow for spreading.
Bake: Pop the cookie sheet into the oven and bake for 10-12 minutes. The edges should be golden, and the centers will stay soft. Don’t worry if they’re a little underdone—they’ll firm up as they cool.
Cool the cookies: After baking, let the cookies rest on the sheet for a few minutes. This helps them firm up before moving them to a wire rack, where they can cool completely and maintain their soft texture.
