- Preheat the oven to 160°C and prepare two baking trays with parchment paper and cooking spray.
- Using the Ninja Foodi Power Blender Ultimate System, add the softened butter, brown sugar, caster sugar, egg, vanilla essence, and peanut butter.
- Attach the lid, then select the DOUGH program and press START/STOP.
- Once the program is complete, add the remaining ingredients and run the DOUGH program again.
- Using a 30ml cookie scoop, portion the cookie dough onto the parchment. Roll each ball with your hands and then indent with a fork.
- Bake until golden brown, turning the cookies halfway through baking, approximately 5 minutes on each side.
