The players cakey creations will be judged by a panel which includes Masterchef food guru Greg Wallace, Baking Mad Ambassador Eric Lanlard and Sainsbury's Director of Brand Judith Batchelar.

Both sets of players will be tasked with trying to bake and decorate 1,000 cupcakes, as well as tackling a signature Chocolate Moelluex cake created by Lanlard. The players' creations will then be judged to see who is crowned Master Baker.

The players will then try and sell as many of their creations to Sainsbury's colleagues before racing round London to continue their sale to raise as much money as possible in just a few hours.

Judith Batchelar, Sainsbury's Director of Brand, added: "As partner to Comic Relief since 1999, we're really excited to team up with the Rugby Players Association to raise as much money as possible for Red Nose Day and Restart. I know from last year's event that the Harlequins team are fantastic bakers so the challengers from Wasps will have to be at the top of their game to take home the victory!"

Details of the winners and photos from the bake-off will be posted on Wednesday as the competition unfolds, so be sure to check our facebook and twitter pages for photos and updates.

Red Nose Day - www.rednoseday.com
• Red Nose Day 2013 is heading your way on Friday 15th March when the great British public will once again be asked to Do Something Funny for Money.
• By raising cash this Red Nose Day, you're helping to change lives forever. That's because Comic Relief spends the money raised to help change the lives of poor, vulnerable and disadvantaged people across the UK and Africa.
• Comic Relief was launched on Christmas Day in 1985, live on BBC One. At that time, a devastating famine was crippling Ethiopia and something had to be done. That something was Comic Relief. The idea was simple - Comic Relief would make the public laugh while they raised money to help people in desperate need. Before too long Red Nose Day was created and the first ever event in 1988 raised a staggering £15m.
• This year, 2013, marks the 25th anniversary of Red Nose Day which has raised over £600m and helped to change lives both in the UK and Africa.
