Start by pre-heating your oven to 375 fahrenheit, then chop up 1/4 cup of cranberry.
Then fold in your tablespoon of flour. Make sure all of the cranberries are coated.
Add your butter, granulated and brown sugar into a bowl and then mix for three minutes.
Crack in your egg, and add your vanilla extract. Mix for a further three minutes.
In a separate bowl, mix your flour, baking soda and salt together.
Then add this into your other mix and combine it all together for a few minutes.
Add your cranberries and white chocolate and mix to create your cookie dough.
Then you can begin to form your cookie balls by pinching a small handful and rolling them in your hands to create a ball.
Add the cookie balls to a lined tray and place them in the oven for fourteen minutes.
Remove your cookies from the oven and allow to cool.
Serve up and enjoy!
