Coffee with marshmallows is so delicious, so it only makes sense that coffee in marshmallows is just as delicious! These homemade flavored marshmallows are made with brewed coffee and coated with cocoa powder making them deliciously indulgent. These Coffee Marshmallows are super simple to make, and are the perfect addition to your coffee or hot cocoa, and are equally delicious straight out of the pan!
Why this recipe works
Marshmallow and coffee make a perfect pair! You can adjust how strong of a coffee flavor you want by adjusting how much espresso powder you use, and how strong you brew the coffee. The sweetness of the marshmallow offsets the bitterness of the coffee, and the cocoa powder coating adds a delicious chocolate balance.
Ingredients and notes
Coffee - Brewed coffee is the flavor profile of these caffeinated marshmallows. A more strongly brewed coffee will result in a more flavorful marshmallow.
Instant Espresso Powder - Adding instant espresso powder to the brewed coffee creates a stronger coffee flavor. Because marshmallows are so sweet, strong coffee is needed to really make the flavor shine. For a more subtle flavored marshmallow, skip the espresso powder.
Cocoa Powder - Cocoa powder is totally optional. It adds a nice touch of a chocolate flavor to these delicious homemade marshmallows, but if you prefer to skip the chocolate, these coffee flavored marshmallows will be equally amazing without the cocoa powder.

Recipe FAQs
The key ingredients to making a marshmallow are gelatin and corn syrup. In this flavored marshmallow recipe, I use brewed coffee to add flavor and sugar to sweeten the treat!
Homemade marshmallows can be stored in an airtight container at room temperature for a few weeks.
This will be dependent on the coffee and espresso powder used. They can be made decaf by using decaf coffee and espresso powder.
Tips & Tricks
- When lining the pan, use binder clips to hold the parchment paper in place.
- Adjust the strength of the coffee flavor by adjusting how much espresso powder is added. For a more subtle coffee flavored marshmallow, do not use any espresso powder.
- Dissolve the instant espresso powder in the hot coffee right after brewing, before letting the coffee come to room temperature.
- When using a candy thermometer, make sure the tip of the thermometer is fully in the mixture, but is not touching the bottom of the pan.
- To make these homemade flavored marshmallows without cocoa powder, use an additional ¼ cup of cornstarch.

I just made these and OMG! We used real espresso instead of coffee and watered it down, used agave instead of corn syrup due to an allergy, and had to beat the mixture for longer (likely due to my substitutions/variances from recipe)… but this recipe works and VERY well and is f***ing delicious! Excuse my language but wow, nice.
