Peanut butter plectrum biscuits

Inspired by a guitar plectrum-shaped cake that my mum made many years ago for my brother’s birthday, I decided to knock up some plectrum biscuits (that’s cookies to you, American cousins). In a nod to Elvis, who died last week in 1977, I flavoured my biccies with peanut butter, famously one of his favourite snacks.

Fender plectrums

I recently procured the Biscuiteers Book of Biscuits, which I used as a basis for this recipe. It’s the first time I’ve used the professional method of separate line and flooding icing, hence the slightly wobbly results. The recipe is a bit long-winded, but it’s all worth it in the end. Here’s what to do…

What you’ll need:

250g plain flour (sieved)
100g soft brown sugar
1/2 tsp baking powder
65g salted butter (softened and diced)
65g golden syrup
1 egg
1-2 tbsp milk
65g peanut butter

For the icing:
180ml cold water
1kg royal icing sugar/mix
Whatever colours you choose (in this case, yellow, blue and black gel colours)

Plectrum biscuit and plectrum

What to do:

Mix the flour, sugar and baking powder together in a large mixing bowl. Add the butter and crumble into the mixture using your fingertips until the mixture looks like fine breadcrumbs. In another bowl, lightly whisk together the egg, syrup, one tbsp of milk and the peanut butter. Tip the liquid mixture into the dry ingredients and mix together until you get a soft dough. Add a dash more milk if it feels too dry. Divide the dough in half and mould each into a flat disc before wrapping in clingfilm and popping in the fridge for at least an hour.

Plectrums

Once chilled, unwrap the dough and place between two sheets of parchment before rolling out to 5mm thickness. Keeping the paper on, put the dough back in the fridge for about 20 minutes (on a baking tray or chopping board). While the dough is in the fridge, pre-heat the oven to 170°C (150°C fan oven)/350°F/gas mark 4. After chilling again, you’re ready to cut out your shapes, either using ready-made cutters or your own templates. To make your own, just draw or trace your design onto a piece of parchment and then stick this a spare piece of card and cut out. You can then bung this on top of you rolled-out dough and cut round it using a sharp knife. Place the shapes on a lined baking tray, leaving plenty of room between each biscuit. Cook for 14 minutes or so (you may need more time, depending on your oven). The biscuits are ready when they start to turn golden brown around the edges. Once out of the oven, transfer to a wire rack and make sure that they’re completely cool before icing, or it won’t stick.

Plectrum biscuits

For the icing:
Chuck the water in a large bowl, then add 900g of the royal icing sugar and whisk together until the icing is roughly the same consistency as toothpaste. You might need to add more icing sugar if it’s not thick enough. For this recipe, you’ll need to save three small bowls of icing at this stage – two for making the outlines and one of the Fender writing. Colour one blue, one yellow and one black, by adding tiny amounts of colouring at a time and mixing in with a fork until you get the colour you want. Take the first outline colour, bung in a disposable icing bag and snip the end to make a small hole. Pipe the outline of a plectrum around the edges of half of your biscuits, making sure that you join the ends up to create a tiny wall of icing. Do the same with the blue icing. Next divide the remaining icing from your original bowl into two parts. This will be your flooding icing, so you need to colour each bowl to match the yellow and blue outline icing. Once done, spoon carefully into the middle of each biscuit and smooth out to the edges using a cocktail stick. Leave to dry.

Colour the third tiny bowl (that you saved earlier) with black colouring, pop into an icing bag and snip of a small section at the end. You might want to practice writing the Fender logo in a piece of parchment before you have a crack at icing your biscuits.

Finally, return your biscuits to a baking tray and place in very cool oven – about 50-70°C/120-160°F/gas mark1/2-3. This may sound like utter madness, but it actually helps to restore the biscuits’ crunch, which can be softed by the moisture in the icing.
