Make the Dalgona coffee mixture: In a bowl, add the coffee powder, sugar, and milk or water and whip on high speed using an electric mixer until the mixture becomes light and fluffy, about 5 minutes.
60 grams granulated sugar, 10 grams coffee powder, 15 ml full-fat milk or water
Whip the whipping cream to soft peaks, then add the Dalgona coffee mixture and whip to stiff peaks.
120 ml liquid whipping cream
Add the coffee whipped cream on top of the top-most biscuit layer, spreading it evenly. You can also pipe the cream on top to make the look fancier. Let the dessert set for at least 2-3 hours or overnight. Top with ripples of melted chocolate, let it set for 10-15 minutes, and serve cold.
30 grams milk or dark chocolate
