Make some cakes, then sell them. Simple and effective. Also, a great supply of endless compliments about your baking prowess.
Mix a bake sale with your own inner competitive nature. Whip out your best cake stand, add extra sprinkles, mix up for flavours...the lot. This is one for those who give their fellow baking colleagues evils on a daily basis. It's time to show 'em whose boss.
For friends who can't bake but can eat
Why not combine your love for your friends with your joy of baking and host an english classic. A team party. A civilised affair where the only alcohol present is in the rum baba... Okay, a glass of champagne is allowed.
