A mocha is a delicious mixture of espresso, chocolate and milk. At a cafe, it can be expensive, sometimes as much as $4-$5 per drink. Making a mocha at home using your espresso machine is a great way to save money, and the drink you make can be every bit as tasty as what you would buy at a cafe.
Pour water into the espresso machine and pack the grounds into the basket. You'll want to refer to the instruction manual of your machine for specific instructions.
Put a carafe or shot glass under the spout and turn on the machine. A demitasse cup works as well---you just need something to catch the espresso.
Put cocoa powder or chocolate syrup in the bottom of a mug. You may want to use more if you like your drinks really sweet.
Heat the milk. If your espresso machine has a steam wand, use that, referring to your instruction manual. If not, heat the milk in the microwave or on the stove. If you want your milk frothed, beat it with an immersion blender or egg beater, or pour it into a blender when it reaches the desired temperature.
Pour the espresso into the mug, then add the milk and stir to incorporate everything.
Scoop the froth from the steamed milk onto the top, or top with whipped cream.
If you are diabetic, you can use sugar-free chocolate syrup. You can adjust the ratio of coffee to milk per your personal preference.
Make sure you follow the directions for your espresso machine as set out by the manufacturer. You can injure yourself if you don't. Be careful not to scald yourself when working with hot milk, especially when using the blender. Keep it covered and follow the manufacturer's safety instructions.
