In a medium bowl, cream coconut oil and sugar. Mix in vanilla and egg until smooth.
Mix in the pudding mix powder, baking soda and flour until well blended. Let the dough sit for 5 minutes.
Stir in chocolate chips and nuts.
Chill for at least 30 minutes. (You can either roll into balls before or after chilling, depending on how big your fridge is!).
Preheat oven to 350F.
After chilling, form 1 tsp cookie dough balls (if not already done so) and place on a prepared baking tray. Slightly press down the balls with the palm of your hand.
Bake for 11-14 minutes, until the edges lose their sheen.
Allow to cool on tray for 5-10 minutes then move to a wire rack to cool completely.
