Preheat the oven to 350° Fahrenheit.

Melt the 2 chocolate bars in a micro-wave safe bowl using the microwave in 20 second increments. Stir after each burst to see if the chocolate if fully melted. Set aside to cool.

In a medium bowl, whisk together flour, cocoa powder, espresso powder, baking powder, and salt. Set aside.

In a large bowl, beat together the butter, brown sugar, and granulated sugar. Beat until smooth and fluffy. Add in eggs and vanilla extract after scraping down the sides of the bowl. Scrape the bowl again before adding the melted chocolate. Mix until well combined.

Slowly mix the flour mixture into large bowl until just combined. Then stir in chocolate chips. Let chill in the freezer for 5 minutes.

Scoop dough into ball approximately 1-1 ¼ inches wide. The cookies will barely spread so make large dough balls to get larger cookies.

Bake for 12-13 minutes. Let cool on the baking sheet for 5 minutes before transferring to a wire rack to cool.
