Nairobi Chai Cheesecake

A layered cheesecake with a chai masala-spiced digestive biscuit crust and a rich cream cheese filling, finished with a tangy passion fruit compote — baked low and slow.

Ingredients

200 grams digestive biscuits, crushed
50 grams/3½ tablespoons unsalted butter, melted (for crust)
1 teaspoon ground cardamom (for crust)
1 teaspoon ginger powder
1 teaspoon ground cinnamon
1 teaspoon ground cloves
2 pinches fine/sea salt
400 grams cream cheese, room temperature
20 grams granulated sugar (for filling)
100 milliliters whipping cream
2 large eggs
1.5 tablespoon plain wheat flour
2 pinches ground cardamom (for filling)
1.5 teaspoon vanilla extract
200 grams fresh passion fruit pulp (or thawed frozen pulp)
10 grams granulated sugar (for compote)
1 teaspoon fresh lemon or lime juice

Method

01
Prep & grease a 9-inch springform pan with some butter.
02
Make the spiced crust: If using fresh/whole spices vs powdered, first grind these in a pestle & mortar before adding to the food processor/blender. Blitz the digestive biscuits with the cardamom, ginger, cinnamon, clove, and sea salt until fine and evenly speckled with spice. Pour in the melted butter and pulse until the mixture looks like wet sand.
03
Press & chill: Press the crumb mixture firmly and evenly into the base of the pan, going slightly up the sides. Then keep in the freezer for 30 min/ fridge for 60 minutes.
04
Beat the base: Beat the cream cheese until completely smooth with no lumps, scraping down the bowl often. Add the sugar and beat until combined, then pour in the whipping cream and mix on low until smooth and glossy.
05
Add flour and eggs: Sift in the flour, 2 pinches of cardamom powder and mix until just combined. Add the eggs one at a time, mixing on low just until each is incorporated, then stir in the vanilla. Avoid overmixing once the eggs go in — this keeps the cheesecake from cracking.
06
Preheat oven at 140°C (285°F) for 10–12 min.
07
Fill and bake low and slow (80–90 min): Pour the filling over the cooled crust and smooth the top. Bake at the same gentle 140°C (285°F) until the edges are set and golden, but the centre still has a gentle wobble like set jelly. Don't open the oven door — temperature swings are the main cause of cracking without a water bath.
08
Cool slowly in the oven: Turn off the oven, crack the door open a few centimeters, and leave the cheesecake inside to cool gradually for 1 hour — this does the job a water bath would otherwise do.
09
Cool and chill: Run a thin knife around the edge of the pan to loosen it, then let it finish cooling to room temperature on a rack. Cover and refrigerate until fully set and chilled through.
10
Make the compote: Simmer the passion fruit pulp, sugar, and lemon or lime juice over medium-low heat, stirring occasionally, until slightly thickened and syrupy. Cool to room temperature — it will thicken further as it cools.
11
Finish: Unmold, slice, and drizzle each piece generously with the passion fruit compote just before serving.

A Little Disclaimer

This one's from my own tinkering — a bit of home (the chai & mandazi spices), meeting the tropical fruit & flavour we like (the passion fruit), put together by feel & tradition. Treat it as a starting point rather than a rulebook: adjust the spice, swap the fruit, and make it yours.

Notes

For clean slices, dip your knife in hot water and wipe it dry between cuts. Thawed frozen passion fruit pulp works well if fresh isn't available. Increase the cardamom and ginger by up to 50% for a bolder chai character. 140°C (285°F) is deliberately gentle — low and slow is what keeps the top from cracking without a water bath, so resist raising the temperature to speed things up. Wheat flour needs roughly double the amount of cornstarch to do the same thickening job, so sift it in to avoid lumps. (Pairs well with a Pinotage from South Africa)
