Place all the ingredients in a large pan and mix with a hand whisker.
Cook in low heat, always stirring with a spatula, until the mixture thickens. To test if it is ready, run a spatula along the length of the pan – if it separates in two halves creating a line in the middle, it has reached the right consistency and you can turn off the heat.
Transfer the brigadeiro to a large bowl and cover it with plastic wrap. Let it cool completely, preferably overnight, in the fridge.
Create the brigadeiro balls by taking about a spoonful of the mixture and rolling them in your hands.
Coat the brigadeiros with ground down speculoos cookies. Keep them in the fridge.
