This chocolate espresso marshmallow fluff is so decadent and easy to make at home. It's made with simple ingredients like honey, gelatin, cocoa, and espresso powder.
Using the bowl of a stand mixer (see notes for hand mixer method) add 1/4 cup of water to the base, and then sprinkle over 1 tbsp of gelatin. Set aside to allow to harden. Add the whisk attachment to the stand mixer for later.
Using a medium stainless steel pot, combine 1/2 cup of water with 1 cup of honey. Set the pot over medium-high heat and heat until it reaches 240 F (use a candy thermometer to check the temperature).
Close the stand mixer and slowly (and carefully) pour the water and honey mixture into the stand mixer as you increase the speed to high speed. Whip the mixture for 6-8 minutes. The mixture should start to get thick.
Add the cocoa powder, vanilla extract and espresso powder. Whip for another 2-3 minutes or so, or until the mixture is very thick like marshmallow fluff!
Spoon the fluff into a large glass container. Store in a cool dry place for up to two weeks, and enjoy as a dip with graham crackers, a filling for whoopie pies, etc.
Notes
You can easily add more espresso powder if you'd like a stronger flavor! You can also use a hand mixer and simply add the water and gelatin to a large bowl instead of a stand mixer base. But keep it mind that it will take longer for the fluff to come together. Keep in mind that this fluff does set at room temperature, but all you have to do is add however much you want to a microwave-safe dish and microwave for about 10 seconds for it to return to its original texture!
