I don't even have an espresso maker - I just use a stovetop espresso maker like this one.
DIY Eggnog Latte
1/2 cup eggnog (or soy eggnog)
1/4 cup whole milk (or soy milk)
1/4 cup espresso
Ground nutmeg (optional)
Mix together the eggnog and milk and heat up, either on stovetop or microwave. Pour the espresso into a mug and top with the hot eggnog/milk mixture, and stir. Sprinkle with ground nutmeg if desired.
