Add the egg and vanilla extract, mixing well.
Bake for 8-10 minutes, until cookies are lightly browned.
Drop tablespoonfuls of dough onto prepared baking sheets, spacing them 2 inches apart.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
In a large bowl, cream together the butter, brown sugar, and granulated sugar until fluffy.
In another bowl, whisk the flour, baking soda, and salt.
Let them cool on the baking sheets for a couple of minutes, then move to wire racks to cool completely.
Preheat the oven to 375°F (190°C). Line baking sheets with parchment paper.
Stir in the dried cranberries and white chocolate chips.
Enjoy these delicious cookies with friends and family!
