Brew a fresh cup of coffee using a drip machine, French press, or another method. Then, pour 200–250 ml (6.8–8.5  fl oz) of coffee into a mug, filling it three-quarters of the way. This will leave enough room for the rest of the ingredients.  You can also buy freshly brewed hot or iced coffee from a coffee shop. If you want to have an iced Amarula with coffee, let the coffee cool down before adding 3-4 ice cubes to the drink. If you are using a smaller mug, use less coffee. Carefully pour the Amarula Cream into a shot glass or jigger. Then, pour the shot into your coffee mug. Mix the drink with a spoon to incorporate both liquids.  If you want a stronger taste of Amarula in your drink, add 2 shots. If you want a more balanced coffee drink, only add 1. Adding too much Amarula to the coffee could overpower the taste of the drink. Press the button on the top of the whipped cream can to spray the whipped cream on top of the coffee. The whipped cream compliments the creaminess in the Amarula and will add sweetness.  Add as much or as little whipped cream as you want. Fat-free whipped cream won't taste as rich as traditional whipped cream. Add 2 g (0.071 oz) of brown sugar and 4-8 marshmallows on top of the drink to add sweetness to the beverage. The sweet notes of the sugar balance out the bitterness of the coffee and the creaminess of the Amarula. If you don't like overly sweet coffee drinks, leave out the marshmallows. The chocolate powder adds richness to the drink. Wait for the beverage to cool off before you drink it so that you don't burn your tongue if the coffee is still hot.

Summary:
Pour coffee into a large mug. Add 1-2 shots of Amarula Cream Liqueur into the coffee and stir it. Spray whipped cream on top of the drink. Sprinkle brown sugar and a few marshmallows on the whipped cream. Finish the drink with hot chocolate powder and serve it.
