Spread the flour evenly onto a baking tray lined with parchment paper. Heat it in the microwave or oven for about 3-4 minutes to heat-treat it, then allow it to cool completely. This step makes the flour safe to eat.
80 g plain flour
Once cooled, sieve the flour into a bowl to remove any lumps and ensure a smooth dough.
In a mixing bowl, beat the butter, granulated sugar, and light brown sugar together until smooth and creamy.
60 g unsalted butter, 25 g granulated sugar, 50 g light brown sugar
Add the milk and vanilla extract, then mix until fully combined.
