Tonight the Great British Bake Off (GBBO) contestants enter the tent with a biscuity challenge on their hands - the key to winning, says The Biscuiteers, is all in the preparation.

Harriet Hastings, managing director of Biscuiteers, says planning will be essential in tonight’s tasks. She says: “Give yourself lots of time and plan ahead to make sure you have all the right equipment. Make a few more biscuits than you need, so that you can practice and test your icing techniques. Invest in good equipment if you can – the right bottles and colours make all the difference.”

For the show-stopper, the GBBO contestants will be faced with the task of making an edible biscuit box, to house 36 biscuits of a different flavour. 3D biscuit-building isn’t easy, as the bakers have witnessed before in past series. The Biscuiteers have put together a step-by-step guide in making a 3D beach hut.

They said: “Other 3D biscuit creations the bakers could make would be a rocket ship, a pirate’s treasure chest, or a builder’s tool box. These are all creative ideas which, if the contestants are careful, can be put together to create a simple but effective edible biscuit box.”

Biscuiteers’ guide to creating a biscuit beach hut.

Step 1: Make your biscuit dough

Step 2: Dust your surface with cornflour and roll out your dough, place a layer of parchment on top of the dough and roll until approximately 0.4mm thick.

Step 3: You can use our template if you like, we just made it from cardboard, cut around each panel, making sure you don’t stretch the dough. You’ll need two of each panel.

Step 4: Carefully lift each panel from the worktop onto a parchment-lined baking tray. Space each panel around 4cm apart, as they may spread while cooking. Then bake in the oven for 14 minutes, or until the biscuits look a golden brown colour.

Step 5: Remove the biscuits from the oven and let cool completely.

Step 6: Prepare your icing as the biscuits are cooling. You’ll need to add a blue line icing border around the outside of all the biscuits to stop the white flood icing from escaping. Let the icing dry for 10 minutes at room temperature, then flood the front and back panels with white flood icing.

Step 7: On your side and roof panels use your white and blue flood line icing to create a striped effect.

Step 8: Put all the biscuits back onto the baking tray and pop in an oven heated to 50°C, or the lowest temperature your oven can go to. You can add some details, like a fishing rod, life raft and maybe a bucket and spade.

Step 9: Now it’s time to construct your house. Using your white line icing, pipe a line on the longer side to each of the side panels, then attach to the front panel and back panel. Let this dry for 10 minutes.

Step 10: Once the side panels have dried and the structure seems sturdy, you can add the roof. Pipe a line on the apex of the roof, then add the two roof panels, holding them in place for around 3-4 minutes, so they can dry.

Step 11: To finish off, you’ll need to cover all the biscuit areas with your line icing. Add a blue line to the roof to cover the seam.
