Preheat the oven to 350°F and line a baking sheet with parchment paper.

In a medium bowl, beat together the butter and brown sugar until light and fluffy.

Add the eggs and vanilla extract and beat to combine.

Add the flour, cinnamon, nutmeg, baking soda, and salt. Beat until smooth.

Fold in the dried cranberries and oats until well blended.

Use a small cookie scoop or tablespoon to scoop out the dough and roll it into a ball. Slightly flatten the ball after placing it on the baking sheet.

Bake the cookies for 10 to 12 minutes, then allow them to cool on the pan for 5 minutes before transferring to a cooling rack to cool completely.
