Why You’ll Love Homemade Coffee Marshmallows Recipe
These marshmallows offer a delicious twist on a classic treat. The deep coffee flavor pairs beautifully with the light, airy texture, making them feel both indulgent and sophisticated. They are customizable in sweetness and intensity, and once you try homemade marshmallows, it’s hard to go back to store-bought versions.
Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
400 g white sugar
100 g corn syrup or honey
120 mL water (for the sugar syrup)
120 mL water (to bloom the gelatin)
18 g gelatin powder
¼ tsp kosher salt or sea salt
2 tsp pure vanilla extract
7 tsp instant espresso powder
1 tbsp water (optional)
120 g cornstarch (sifted)
60 g confectioner’s sugar (sifted)
3 tbsp cocoa powder (optional)
Directions
Start by blooming the gelatin. Place water in a mixing bowl, sprinkle gelatin over it, stir, and let it sit for at least 10 minutes.
Prepare the dusting powder by sifting together confectioner’s sugar, cornstarch, and cocoa powder if using. Set aside.
Grease a 9 x 9 inch pan with butter or shortening and dust it with the prepared powder or line it with parchment paper.
To make the sugar syrup, combine sugar, water, and corn syrup or honey in a saucepan. Heat gently until dissolved, then bring to a boil. Cover briefly to dissolve any crystals, then continue cooking until the syrup reaches 240–245°F.
Whisk the bloomed gelatin briefly, then slowly stream in the hot syrup while mixing. Increase speed and whip until the mixture becomes thick, glossy, and triples in volume.
Dissolve the espresso powder in vanilla extract with a bit of water, then add it to the marshmallow mixture. Continue whisking until evenly combined.
Spread the mixture into the prepared pan while still warm. Smooth the top and dust generously with the powder mixture.
Let the marshmallow set at room temperature for at least 6 hours.
Once set, turn it out onto a dusted surface, cut into squares, and coat each piece with more dusting powder before storing.
Servings and timing
This recipe yields about 64 marshmallows depending on the size of the cuts.
Preparation time is approximately 55 minutes, with an additional setting time of at least 6 hours, making the total time around 6 hours and 55 minutes.
Variations
You can adjust the intensity of the coffee flavor by adding more or less espresso powder. For a mocha version, include cocoa powder in the marshmallow base. Vanilla-only marshmallows can be made by omitting the coffee entirely. You can also swirl in melted chocolate before setting for a marbled effect.
Storage/Reheating
Store the marshmallows in an airtight container at room temperature. They will stay fresh for up to two weeks. Keep them well coated in the dusting mixture to prevent sticking.
Avoid refrigerating as it can introduce moisture and affect texture. These marshmallows do not require reheating but can be lightly toasted if desired.
FAQs
Can I use regular coffee instead of espresso powder?
No, liquid coffee will alter the texture. Instant espresso powder provides flavor without adding excess liquid.
What if I don’t have a thermometer?
You can use the cold water test to check for the firm-ball stage, though a thermometer is more reliable.
Why are my marshmallows sticky?
They may not have enough dusting powder or were exposed to humidity.
Can I make these without corn syrup?
Yes, honey works as a substitute and provides a slightly different flavor.
How do I cut marshmallows cleanly?
Lightly grease your knife or scissors and clean between cuts.
Can I freeze marshmallows?
Freezing is not recommended as it affects texture.
How strong is the coffee flavor?
It’s moderate but can be adjusted by adding more espresso powder.
Can I color these marshmallows?
Yes, you can add food coloring during the whipping stage.
Why didn’t my marshmallows set?
The syrup may not have reached the correct temperature, or the gelatin may not have bloomed properly.
Can I double the recipe?
Yes, but ensure your mixing bowl is large enough to handle the volume.
Conclusion
Homemade coffee marshmallows are a delightful treat that combines the comforting sweetness of marshmallows with the bold richness of coffee. With a bit of patience and attention to detail, you can create a batch that’s far superior to anything store-bought and perfect for any occasion.
