Preheat oven to 350°F (175°C) and line your baking tray like a responsible adult.
Mix flour, cocoa, baking soda, and salt in a bowl. Pretend you’re on a cooking show.
In another bowl, beat vegan butter with both sugars until creamy and slightly smug-looking.
Stir in vanilla and plant milk until combined and smooth.
Fold in dry mixture and stir until dough forms and looks totally edible (but don’t).
Scoop into tablespoon-sized portions, flatten slightly, and space them out on the tray.
Bake for 10–12 minutes and cool on a rack unless you love gooey hand disasters.
Beat cream ingredients until smooth and thick enough to spread with sass.
Slather that coffee filling onto half the cookies like you mean it.
Sandwich with the other halves, admire your work, and devour without remorse.
