Gather all your ingredients and tools. Clean your kitchen counter and preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper.

In a large bowl, whisk together flour, cocoa powder, granulated sugar, brown sugar, and salt until combined.

In another bowl, melt unsalted butter. Add eggs and vanilla extract, whisking until well combined and fluffy.

Pour the wet mixture into the dry ingredients and stir with a spatula until just blended; a few lumps are fine.

Fold in the semi-sweet chocolate chips evenly throughout the dough.

Scoop tablespoon-sized balls of dough and place them on the prepared baking sheets, leaving space between each.

Bake in the preheated oven for 10-12 minutes. Edges should be set, but the centers should look soft.

Let cookies cool on the baking sheets for about 5 minutes, then transfer to a wire rack to cool completely before enjoying.

Clean your workspace as you enjoy the cookies.
