A low (ish) and slow (ish) temperature does the trick for this bread pudding for the mass duration of its cook time. However, at the very end, you're going to crank the heat up, sprinkle a mixture of white sugar, brown sugar, and cinnamon evenly over the pudding, and allow the top to caramelize into a pleasantly crunchy finish.
Temper the yolks and mix with the cream: While whisking the yolks continuously, slowly add one ladle (about 1/4 or 1/3 cup) of hot cream in a thin stream. Do this two or three more times. While whisking, slowly add the remaining cream to the egg mixture, followed by the vanilla extract.
Place 3 tablespoons of sugar in each llanera. Set the llanera on the stovetop over low heat, and using tongs, move llanera repeatedly over flames until sugar is melted and turns to honey gold. Continuously tilt and swirl the llanera to ensure even melting and to distribute the liquid on the bottom of the mold.
Pour 2 cups of water (room temperature) into a small pot. Sprinkle 1 teaspoon of gelatin and stir until dissolved. Bring to a boil. Add milk, sugar, and cocoa powder and stir until dissolved. Pour into the molds halfway full. Pour another cup of water into a pot. Sprinkle remaining gelatin and stir until dissolved.
