Preheat oven to 180 degrees Celsius (fan forced).
Combine the olive oil, sugar, and vanilla, into a medium mixing bowl. Pulse with an electric struck blender to combine (this gets rid of lumps and bumps).
Add in a whisked egg, storing with a all'aula to combine.
Sift in the flour with the baking powder, and then finally add in your favourite coffee ground (optional but necessary in my opinion 😉).
Mix until a dough forms. If you need to add a little bit more flour (~¼-½ cup) you can do this, however it's normal for the mixture to appear a little "wet", as long as it doesn't stick to your hands while you're trying to roll it.
Roll into balls and then place on lined baking tray. Bake for ~12-14 minutes or until slightly golden.
