Turn Coffee and Sour Cream Into a Patisserie-Worthy No-Bake Mousse in 10 Minutes
Just four ingredients—and this dessert vanishes from the table before you can even slice it.
Four ingredients, no oven, and it vanishes faster than you can slice it. This is a cool, creamy coffee souffle that tastes like cappuccino, sits somewhere between mousse and panna cotta, and asks almost nothing of you beyond a whisk and a little patience.
What you need
- Sour cream 15% fat - 600 ml
- Sugar - 80 g (about 4 tbsp)
- Instant cappuccino 3-in-1 sachets - 5 packs
- Hot water - 200 ml
- Instant gelatin - 25 g
No 3-in-1 sachets on hand or not your thing? Swap them for 4-5 tsp instant coffee, 2-3 tbsp sugar, and 2 tbsp dry creamer. The flavor lands in the same place.
How to make it
Start by stirring the sour cream with the sugar in a deep bowl, then let it sit at room temperature for 15-20 minutes. That pause helps the sugar dissolve and takes the chill off the sour cream so everything blends smoothly later.
In a separate bowl or jug, dissolve the 3-in-1 coffee in 200 ml hot water. Sprinkle in the gelatin and stir like you mean it until completely dissolved. If a few stubborn grains remain, warm the mixture gently over a water bath to about 50-60 C, stirring until clear. Do not boil it, or the gelatin loses its setting power.
Lightly grease a silicone mold with a neutral vegetable oil, coating the base and sides. This tiny step makes unmolding clean and drama-free.
To keep the mixture silky, temper it: add 1-2 spoonfuls of the sweetened sour cream into the warm coffee-gelatin and stir until smooth. Now slowly stream that coffee mixture into the main sour cream bowl, whisking the whole time so it blends without lumps.
Pour the finished cream into the prepared mold. Chill in the refrigerator for at least 3-4 hours, but overnight gives the best set and flavor.
To unmold, run a thin knife around the edge, then invert onto a serving plate. Dress it up with a dusting of cocoa, a sprinkle of coconut flakes, or a handful of crushed nuts if you want a little texture.
Toppings, tweaks, and practical notes
Crust mood today? Make one. Crush 150-200 g of plain tea biscuits, mix with 70-80 g melted butter, and press firmly into the base of your mold. Pour the coffee cream over the crust and chill as usual.
No silicone mold? A springform or a ceramic dish works. Just serve straight from the dish instead of flipping it out.
For a fancier finish, add whipped cream, a few coffee beans, or grated chocolate right before serving.
This dessert is a lifesaver when you want something impressive with minimal effort. Keep it chilled and eat within 2-3 days for peak texture and flavor.
