"Little drunks" are small, soft candies flavored with fruit and a splash of liquor. This colorful, family-friendly confection is a sweet, fruity, traditional Mexican candy treat.
In a medium saucepan, whisk together the sweetened condensed milk, whole milk, and cornstarch until smooth with no lumps.
Place the saucepan over medium-low heat, stirring constantly with a heatproof spatula to prevent sticking and burning. Cook until the mixture starts to thicken, about 6–8 minutes.
Once thickened, add unsalted butter and continue to stir for another 2–3 minutes until the mixture forms a soft dough that begins to pull away from the sides.
Remove from heat and immediately mix in the fruit liqueur and vanilla extract. If coloring, divide the dough and tint each portion as desired.
Let the candy dough cool to room temperature. Dust your hands with powdered sugar, then roll the cooled mixture into small bite-sized pieces and coat again in powdered sugar before serving.
