Preheat your oven to 350°F (175°C) to ensure even baking.
In a microwave-safe bowl or a double boiler, melt the chopped semisweet chocolate until smooth. Set aside to cool slightly.
In a separate bowl, whisk together the flour, cocoa powder, baking powder, and salt.
In a large mixing bowl, beat the softened butter, brown sugar, and granulated sugar until light and fluffy, about 2-3 minutes.
Add the eggs, vanilla extract, and instant coffee to the butter mixture, mixing until well combined.
Fold the melted chocolate into the wet ingredients until fully incorporated.
Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Fold in the chocolate chips, ensuring even distribution.
Scoop rounded tablespoons of dough onto lined baking sheets, spacing them about 2 inches apart. Bake for 12-15 minutes.
Allow the cookies to cool on the baking sheets for about 5 minutes before transferring them to a cooling rack.
