Whole Wheat Chewy Chocolate Chip Cookies

Preheat the oven to 350 degrees F (175 degrees C).

Combine whole wheat flour, brown sugar, butter, eggs, coffee liqueur, cocoa powder, salt, baking soda, and vanilla in a large bowl. Beat with an electric mixer until blended but still a little lumpy. Fold in chocolate chips with a spatula. Drop heaping tablespoons of dough onto ungreased baking sheets.

Bake in the preheated oven until golden brown, 12 to 14 minutes. Let rest on the baking sheets, 1 to 2 minutes; remove to a wire rack to cool completely.
