Step-by-Step Instructions
Step 1: Prepare the Chocolate Biscuit Base
-
Line the Pan: Lightly grease the base and sides of your 9-inch springform pan. For easy removal, you can line the base with a circle of parchment paper.
-
Crush the Biscuits: Place the digestive biscuits in a food processor and pulse until you have fine crumbs. If you don’t have a processor, place them in a sturdy zip-top bag and crush with a rolling pin until uniformly fine.
-
Combine: In a medium bowl, mix the biscuit crumbs, melted butter, sugar, and cocoa powder. Stir until the mixture resembles wet sand and every crumb is coated.
-
Press and Chill: Transfer the mixture to the prepared springform pan. Press it down firmly and evenly into the base using the back of a spoon or a flat-bottomed glass. Chill in the refrigerator for at least 30 minutes to set while you make the filling.
Step 2: Create the Cheesecake Filling & Swirl
-
Bloom the Gelatin: In a small bowl, sprinkle the gelatin powder over the 3 tablespoons of boiling water. Whisk immediately with a fork until the gelatin is completely dissolved and no granules remain. Set aside to cool slightly.
-
Whip the Cream: In a large bowl, using an electric mixer, whip the cold heavy cream until it forms soft peaks. Be careful not to overwhip. Set aside.
-
Cream the Cheese: In a separate, larger bowl, beat the room-temperature cream cheese, caster sugar, and vanilla extract together until completely smooth, creamy, and free of lumps. This should take about 3-4 minutes. Scrape down the sides of the bowl as needed.
-
Incorporate Gelatin and Bailey’s: With the mixer on a low speed, gradually pour in the dissolved gelatin, ensuring it is fully incorporated. Then, slowly pour in 100ml of the Bailey’s Irish Cream, mixing until just combined.
-
Fold in the Whipped Cream: Using a spatula, gently fold the whipped cream into the cream cheese mixture in two additions. Be gentle to maintain as much air as possible, which gives the cheesecake its light texture.
-
Divide and Flavour: Spoon about one-third of the plain cheesecake filling into a separate bowl. Pour the remaining 50ml of Bailey’s into this smaller portion and fold it in until fully combined. You now have a larger portion of plain filling and a smaller portion of Bailey’s filling.
-
Assemble the Swirl: Retrieve the chilled base from the refrigerator. Spoon large dollops of the plain cheesecake filling over the base, spreading it out roughly. Next, dollop the Bailey’s-flavoured filling randomly on top. Use a skewer or the tip of a knife to gently swirl the two fillings together to create a marbled effect. Avoid overmixing, or you will lose the definition.
-
Smooth the Top: Gently smooth the top with a spatula or palette knife.
Step 3: Make the Bailey’s Ganache & Final Chill
-
Prepare the Ganache: Place the finely chopped dark chocolate in a heatproof bowl. Heat the 100ml of heavy cream in a small saucepan over medium heat until it just begins to simmer (small bubbles around the edges). Pour the hot cream over the chocolate and let it sit for 2-3 minutes.
-
Whisk and Add Bailey’s: Whisk gently until the chocolate has melted and the mixture is smooth and glossy. Whisk in the 2 tablespoons of Bailey’s Irish cream.
-
Top the Cheesecake: Allow the ganache to cool for 5-10 minutes so it thickens slightly but is still pourable. Pour it over the swirled cheesecake filling, tilting the pan to create an even layer.
-
The Long Chill: Carefully transfer the cheesecake to the refrigerator. Chill for a minimum of 6 hours, but for the best results and the perfect slice, let it set overnight (8-12 hours).
Step 4: Serving
-
Release the Cheesecake: To serve, run a thin, warm knife around the edge of the springform pan. Release the clasp and carefully remove the ring.
-
Slice Cleanly: For pristine slices, dip a sharp knife in hot water, wipe it dry, and then make a cut. Repeat this process for each slice.
-
Garnish and Enjoy: Serve the slices as they are, or garnish with a little whipped cream, chocolate shavings, or a drizzle of extra Bailey’s.

Chef’s Notes & Tips for Success
-
Room Temperature is Key: Ensuring your cream cheese is at room temperature is non-negotiable. It prevents a lumpy filling and makes for a smoother, airier texture.
-
Gelatin Substitute: For a vegetarian option, you can use agar-agar. Follow the package instructions to substitute for the gelatin powder, as the conversion is not 1:1.
-
Don’t Over-swirl: The key to a beautiful marbled effect is a light hand. Just a few figure-eight motions with a skewer are enough.
-
Chill Time is Not Optional: This cheesecake sets in the fridge. Rushing this step will result in a runny slice. Patience is your greatest tool here.
-
Storage: Store any leftovers covered in the refrigerator for up to 5 days. This cheesecake does not freeze well due to the cream and Bailey’s content.
