Method

  1. Beat the 150 g unsalted butter and 90 g caster sugar together until pale and fluffy.

    prep · 5m

  2. Beat in the 3 ½ egg yolks (56 g) and 6 g vanilla extract until fully combined.

    prep · 3m

  3. Sift the 200 g cornflour, 100 g plain flour, 5 g baking powder, 3 g bicarbonate of soda and 2 g fine sea salt together, then fold into the butter mixture just until a soft dough comes together. Avoid overworking it.

    prep · 5m

  4. Wrap the dough and chill it for 30m, until firm enough to roll.

    rest · 30m

    The dough is soft from the high proportion of cornflour and butter to gluten-forming flour. Chilling it firms the butter enough to roll and cut cleanly without the rounds spreading and losing their shape in the oven.

  5. Roll the dough between two sheets of baking paper to the thickness of a coin and cut into small rounds, gathering and re-rolling the scraps. Set the rounds on lined trays, spaced well apart, since they spread very little and are cut close together to keep an even thickness.

    prep · 15m

  6. Bake at 170 °C for 12m, until the tops look dry and set rather than coloured. The rounds will still feel soft in the centre; they firm up entirely as they cool.

    cook · 12m

    Common pitfallThese are pale cookies by design: cornflour does not brown the way wheat flour does, so colour is not a useful guide to doneness. They are done when the tops look dry and set rather than when they take on colour, and a batch left in until it looks golden is already overbaked and crumbly instead of tender.

  7. Slide the rounds onto a rack and cool completely, for 15m, before filling: a warm cookie melts the dulce de leche straight through it.

    rest · 15m

  8. Spread half the rounds generously with the 280 g dulce de leche and sandwich with the remaining rounds, pressing gently so the filling meets the edge all the way round. Roll the exposed rim of filling in the 120 g desiccated coconut to coat it.

    prep · 15m

Ahead of timeThe dough can be made up to two days ahead and kept chilled, wrapped, until ready to roll. The baked, unfilled rounds keep in an airtight tin for up to three days.
FreezingFreeze the baked, unfilled rounds layered with baking paper for up to two months; thaw before filling, since the dulce de leche does not freeze well between the layers.
