# How to Make It:

02 - Whisk together flour, baking soda, salt, cinnamon, and nutmeg in a medium bowl until evenly blended.
03 - Using an electric mixer or wooden spoon, beat softened butter with light brown sugar and granulated sugar until mixture is light and fluffy, approximately 2 to 3 minutes.
04 - Incorporate eggs one at a time, beating thoroughly after each addition, then blend in vanilla extract.
05 - Slowly add the dry mixture to the wet ingredients, stirring just until all components are incorporated.
06 - Gently fold rolled oats and raisins into the dough using a spatula until evenly distributed.
07 - Drop dough in rounded tablespoons onto prepared baking sheets, spacing each cookie approximately 2 inches apart.
08 - Bake in preheated oven for 10 to 12 minutes, until cookie edges are golden and centers appear slightly underbaked.
09 - Allow cookies to rest on baking sheets for 5 minutes, then transfer to a cooling rack to reach room temperature.
