Preheat Oven at 350

In a medium-large bowl add your stick of butter at room temp, brown and white sugar. Mix with an eletric mixer

Add the egg when the butter and sugar are complelty combined. Mix with mixer.

Add the flour, baking soda, salt and vanillia to batter. Mix with mixer untill completly combined.

Add the peanut butter and oats. Mix again.

Add chocolate chips and stir in with spoon.

I use an ice cream scooper but a spoon would work also when putting dough on sheet. I also lay down parchment paper.

Cook for 8-10 mins
