Wrapped up against the biting cold, the Duchess of Cambridge arrived wearing a green woollen hat, fleece, green parka-style jacket, dark blue jeans and wellies with a Scout's red, white and blue neckerchief, tied in a friendship knot.
As snowflakes were blown around the fells above Lake Windermere at the Great Tower activity centre near Newby Bridge, the temperature was estimated to have plummeted to minus five with the wind chill factor.
Kate, five months pregnant, spent about an hour outside with adult scout volunteers and youngsters.
The Duchess of Cambridge joined 24 other adults on a training day to learn scouting skills to pass on to children at their own groups.
As part of the day Kate learnt how to make "twisters" or "dampers".
She kneaded dough in a bowl for several minutes before making elongated twists. After washing the dough mix off her hands Kate wrapped a twist of the messy mixture around a twig stripped of bark which was placed over the open fire ready to toast.
The volunteers' efforts had mixed results, with the Duchess laughing and giggling with the others as some of the twisters dropped into the flames.
"I'm not sure if these are going to look particularly edible," Kate laughed.
After several minutes toasting on the fire Kate pulled off a piece of the bread and, rather gingerly, popped it in her mouth. "Oh, its actually not bad," she told the group. "It is quite sugary though."
The Duchess of Cambridge wrapped up against the snow and got stuck into some outdoor cooking during a visit to a Scout camp in the Lake District.

Kate, who is a volunteer in the Scout Association, joined fellow adult volunteers as they trained to work with Beaver and Cub Scouts at the Great Tower Scout Camp near Newby Bridge in Cumbria.
She will use her training to help look after a group of Cub Scouts from Cumbria and Manchester taking part in a pack holiday event at the 250-acre activity centre close to Windermere.
The Girl Guiding Association says that the online consultation on the future of the organisation's oath of allegiance will allow them to match their members needs better.
The Girl Guides are considering removing references to God and the Queen from their oath of allegiance as the organisation seeks to attract new volunteers.
Thousands of girls are on waiting lists to join the Rainbows, Brownies and Guides because of a lack of trained volunteers to help run events.
The president of the National Secular Society, Terry Sanderson, said the Scouts' consultation on an alternative oath for atheists was a "move in the right direction".
He also said it would put an end to "unpleasant confrontations" such as that of 11-year-old George Pratt, from Midsomer Norton in Somerset, who was excluded because he did not want to make the Scout Promise in its present form.
Membership of the Scouts has risen during the past seven years from 444,936 in 2005 to 525,364 this year, figures released by the association show.
Since 2002, the number of girls taking part has increased by 69% while more than 50 scout groups catering for young people drawn mainly from Muslim, Hindu and Sikh communities have opened in the last ten years.
The existing Scout Promise contains a vow of allegiance to the God and the Queen .
Alternative versions allow Hindus and Buddhists to use the word "my Dharma" while Muslims can use the word "Allah".
Non UK citizens are permitted to replace the phrase "duty to the Queen" with "duty to the country in which I am now living".
