This Oatmeal Raisin Cookies recipe will surely be your new tried and true oatmeal cookie recipe. It's a good thick old-fashioned cookie with a little cinnamon and raisins.
If soaking raisins in warm water, do that now. Make sure you dry them completely before using.
Melt butter and let cool slightly.
Mix flour, baking soda and salt; set aside.
In a medium bowl, mix together the melted butter, brown sugar and white sugar until well blended. Beat in the cinnamon, vanilla, egg, and egg yolk for 2-3 minutes until light and creamy. Mix in the flour mixture until just blended. Add the oats, nuts, and raisins. Mix until just blended.
Chill dough in the fridge for 30-60 minutes. If chilling longer, let dough sit at room temperature for about 30 minutes so it's not too hard to scoop.
When ready to bake, preheat the oven to 325 degrees. Line cookie sheets with parchment paper.
Place 1/4 cup balls of dough onto parchment lined cookie sheet and bake for 14-16 minutes. Do not overbake. The edges should look brown and the centers still slightly soft. Let the cookies rest on the cookie sheet for a couple of minutes before transferring to a cooling rack. Add a sprinkle of flaked salt if desired.
