To prepare a spicy mexican hot chocolate cookies recipe, first you need to prepare the ingredients for the cookies. First, you'll need: 1 cup (240 ml) granulated sugar, 1 tablespoon (2.5 g) vanilla extract, and 1 teaspoon (0.5 tsp) salt. Then, add the dry ingredients to the wet ingredients and mix until they're just combined. Add the melted chocolate and stir until it's fully incorporated. Pour the mixture into an oiled cookie sheet and bake for 12 to 15 minutes or until the edges are golden brown. Remove from the oven and allow to cool for 5 minutes before serving.
