Paul’s Fortune Cookies

No doubt feeling particularly cruel, Paul’s fortune cookie recipe left most of these bakers in a panic, with a particularly bare recipe that left out key steps. How do you get those cookies so thin? How do you get its signature, dainty folds? Paul, for God’s sake, you left our amateur bakers wandering in the proverbial wilderness!

Flo’s Gin Jam Butties

Flo had us itching to try out these deceptively innocent-looking, gin and cream filled sandwiches. The results will surely be worth the slightly more expensive price of £9.37 per batch, no doubt thanks to the fresh raspberries and gin. Adorable, and for adults.

Peter’s Coconut Cake

Can you tackle Prue’s Choccy Mini Rolls? Make sure you don’t dry out the sponge!

Peter won over the viewers with his cheery disposition. Shame he couldn’t win over Paul, who took one bite of this Coconut Cake only to find it had burnt his mouth! How much baking powder did you put in this Peter?!

Prue didn’t seem to mind as much. She was bowled over by the coconutty taste sensation of this bake.
