Pour in the espresso. Then gently spoon the mascarpone cream on top. Dust with cocoa powder on top and serve immediately.
Notes
Espresso works best. But if you are using instant coffee instead, mix 2 teaspoons of instant coffee with ¼ cup of hot water. Instant coffee doesn't quite replicate the taste of a good espresso, but this method would be close enough.
Baking cocoa powder is typically unsweetened and works perfectly for this recipe to enhance the coffee and tiramisu flavour. Do not substitute with instant chocolate powder.
Make sure to whisk the mascarpone cream properly until soft peaks form before topping it on the latte. If under-whisked, the cream layer would be too dense and sink into the latte.
Hot espresso could also melt the cream topping layer. Let the espresso cool down for 1-2 minutes would be ideal to keep your presentation on point.
