Start by browning the butter. Measure the butter into a saucepan and place over medium heat. Stir until melted. Continue to heat for another 5ish minutes, swirling the pan occasionally, until the melted butter is foamy on top, a golden amber colour beneath and has a nutty aroma. There should be brown flecks in the bottom of the saucepan. Pour into a mixing bowl and leave to cool for 10 minutes.
160 grams Unsalted butter
Add both sugars and mix to combine.
150 grams Light brown sugar, 100 grams White caster sugar
Add the egg, egg yolk, and vanilla extract and mix to combine.
1 medium Egg, 1 teaspoon Vanilla extract, 1 medium Egg yolk
Add the flour, cornflour and salt. Fold to make a thick cookie dough.
Cover the bowl with clingfilm and refrigerate for 15 minutes. This allows the flavours to further develop.
Preheat the oven to 180°C fan / 200°C conventional and line two large baking trays with greaseproof paper.
Scoop up heaped tablespoons of cookie dough and roll into balls (you should be able to make 12 in total). Arrange 6 balls on each baking tray, leaving space between each so they have room to spread.
Bake on the middle shelf of your oven for 10 minutes until golden around the edge. The middle should look a little underbaked. Leave to cool on the baking tray for at least 20 minutes.
For the decoration, top each cookie with a teaspoon of pistachio cream, a scattering of pistachios and a sprinkle of flaky sea salt. Enjoy!
100 grams Pistachio cream, 25g Pistachios (shelled), Sea salt flakes
