Preheat your oven to 325°F (160°C).
In a double boiler, combine the heavy whipping cream, Kahla, vanilla extract, and instant espresso powder. Stir until hot but not boiling, then remove from heat and let cool slightly.
In a large mixing bowl, whisk together the egg yolks, brown sugar, and cinnamon until well combined and slightly thickened.
Slowly pour the warm cream mixture into the egg yolk mixture, whisking continuously to prevent the eggs from scrambling.
Strain the custard through a fine-mesh sieve into another bowl to ensure a silky-smooth texture.
Place your ramekins in a baking dish and pour the custard mixture evenly into each ramekin, filling them about three-quarters full.
Create a water bath by carefully pouring hot water into the baking dish around the ramekins. Bake for 30-35 minutes, or until the edges are set but the centers are slightly jiggly.
Remove the ramekins from the water bath and let cool at room temperature. Refrigerate for at least 4 hours or overnight.
When ready to serve, sprinkle a thin layer of raw sugar on top of each custard and caramelize using a culinary torch.
Top each crème brûlée with freshly whipped cream, a sprinkle of cinnamon, and a few chocolate-covered coffee beans. Enjoy!
