1cupcold, unsalted butter, cut into small cubesfreezing butter slightly makes it easier to cut into cubes
1 1/4cupsgranulated sugar
½cupdark cocoa powder
2 ¼cupsall-purpose flour
2 ½cupssemi-sweet chocolate chips
Preheat the oven to 350˚ F. Line baking sheets with parchment paper or silicone baking mats. In the bowl of an electric mixer, combine the butter and sugar. Beat together on medium-high speed until light and fluffy, 2-3 minutes. Blend in the eggs one at a time, scraping down the bowl as needed. Mix in the cocoa powder until well blended.
Add the flour, salt and baking powder to the bowl and mix on low speed just until incorporated. Fold in the chocolate chips with a spatula.
Transfer the dough to a work surface and knead briefly by hand to be sure the ingredients are well combined. This dough is VERY thick. I kneaded mine in the bowl, and that worked out just fine.
Divide the dough into 4 ounce portions (or divide into 12 equal pieces). Roll each portion of dough into a ball and flatten just slightly into a disc. Place on the prepared baking sheets, a few inches apart.
Bake 16-20 minutes. Let cool on the baking sheets 5-10 minutes, then transfer to a wire rack to cool completely.
These cookies are LARGE! They are closer to the size of a hamburger patty than your typical cookie!
