Preheat oven to 350 degrees.

In a mixing bowl cream together peanut butter, butter and sugars.

Add eggs and vanilla and mix until combined.

Add flour, oats, salt, baking soda and baking powder.

Mix until all combined.

Add m&ms and chocolate chips and gently mix until they are incorporated in the dough.

For mini cookies I use a melon baller to scoop out the dough to form balls.

Put cookie balls on a baking sheet.

Place candy eyes and more m&ms on top of the cookies.

Bake for 8-10 minutes. (Both mini and regular sized cookies)
