In a non-stick pan or skillet over low heat, pour fresh milk.

Bring to a gentle simmer then add sugar and stir until sugar dissolves.

Cook for 45 - 55 minutes while regularly stirring or until milk is reduced and paste-like in texture.

Remove from heat then while still warm add butter. Mix until butter dissolves and incorporated.

Transfer in a bowl then add powdered milk. Mix until fully incorporated and soft dough forms. Let it completely cool down or until cool to touch.

Transfer dough into a clean flat surface then roll into a 4 inch log and divide into 4 equal pieces.

Take one piece and roll into a 10 inch cylinder then cut into 10 equal pieces.

Roll smaller pieces into 1 inch length cylinders. Repeat process with the rest of the dough.

Dredge pastillas in sugar to coat and wrap if you wish to. Serve and enjoy. Bon appetit!
