Stir flaxseed with water and let it thicken like your skincare routine.
In a bowl, mix flour, cocoa powder, salt, and baking soda.
In another bowl, cream vegan butter, brown sugar, and white sugar until smooth.
Add flax egg, espresso powder, and vanilla extract. Mix until combined.
Add dry mix to wet. Stir just enough to make dough—don’t overdo it, this isn’t cardio.
Fold in chocolate chips like they’re treasure.
Chill dough for 30 minutes. Chill yourself with a coffee while you wait.
Meanwhile, whip all filling ingredients until creamy. Set in fridge to firm slightly.
Scoop cookie dough into balls, flatten slightly, and spoon in a little coffee cream.
Cover with another flattened dough disk and seal the edges gently.
Bake at 350°F (175°C) for 12–13 minutes until edges are just set and centers puff up.
Cool before eating or risk lava-level filling on your face.
