Preheat the oven to 350°F (180°C).

In a large bowl, mix the flour, sugar, and baking powder.

Add the butter and mix until crumbly.

In a separate bowl, whisk together the egg yolks, vanilla extract, and milk.

Add the egg mixture to the flour mixture and stir until the dough comes together.

Divide the dough into two equal parts.

Roll out one half of the dough to fit a 9-inch (23cm) cake pan.

Place the rolled-out dough in the cake pan and spread the dulce de leche on top.

Roll out the other half of the dough and place it on top of the dulce de leche layer.

Brush the top with a beaten egg and sprinkle shredded coconut on top.

Bake for 30-35 minutes or until golden brown.

Let the torta cool before serving.
