Oatmeal raisin chocolate chip cookies are soft, cinnamon spiced oatmeal cookies filled with raisins and chocolate chips. These cozy cookies have chewy centers with crisp, buttery edges.
In a large mixing bowl fitted with a paddle attachment, add the softened butter, light brown sugar and granulated sugar. Mix the butter and sugars on medium speed for 2 - 3 minutes or until the butter and sugars are well combined.
On low, cream in the egg, egg yolk, vanilla extract and molasses until smooth and well combined. With the mixer on low, add the dry ingredients into the wet a little at a time. Mix until just combined.
Gently fold in the old fashioned oats, raisins, chocolate chips and mini chocolate chips one at a time until well combined. Wrap the cookie dough in plastic wrap and transfer to the fridge to chill for 30 minutes - 2 hours.
Using a medium cookie scoop (2 tablespoons, 30 ml), scoop the oatmeal raisin and chocolate chip cookie dough into balls and place them onto the lined baking sheet about 3 inches (8 cm) apart.
Bake the oat chocolate chip raisin cookies at 350 F (177 C) for 11 - 13 minutes or until the edges of the cookies are set and are a light golden brown. The center of the cookies will be slightly puffed up.
Cool the oatmeal raisin chocolate chip cookies on the baking sheet for 5 minutes. Then transfer to a cooling rack to cool completely to room temperature and enjoy.
