cooking spray
850g cream cheese, at room temperature
200g white sugar
4 large eggs
240ml sour cream
0.5 teaspoon vanilla extract
3 tablespoons all-purpose flour
150g packed dark brown sugar
160ml canola oil
1 egg
120g all-purpose flour
0.75 teaspoon ground cinnamon
0.5 teaspoon baking powder
0.5 teaspoon salt
100g grated carrots
80g chopped walnuts
250g confectioners' sugar
115g cream cheese
1 teaspoon almond extract
Step 1
Preheat the oven to 175°C and position the racks in the center and lower third. Fill a roasting pan halfway with water and place it on the lower rack. Grease a 23cm springform pan with cooking spray.
Step 2
To make the cheesecake filling, beat the cream cheese in a large bowl with an electric mixer on high speed until fluffy. Add sugar and beat on medium-low speed for 2 minutes. Beat in eggs, one at a time, mixing well after each addition. Mix in sour cream and vanilla until smooth. Stir in flour and set aside.
Step 3
For the carrot cake layer, beat brown sugar and oil in a second large bowl with an electric mixer on medium speed until smooth. Add egg and beat for 2 minutes. Mix in flour, cinnamon, baking powder, and salt on low speed until combined. Fold in carrots and walnuts.
Step 4
Spread the carrot cake batter into the prepared pan, then pour the cheesecake batter over the top.
Step 5
Place the cake into the preheated oven on the center rack (above the roasting pan with water). Bake until the cheesecake is set, about 1 hour and 10 minutes, covering the top with aluminum foil if browning too quickly. Remove from the oven, place onto a wire rack, and let cool for 10 minutes.
Step 6
Run a knife around the edge of the pan to loosen the cake, then let it cool to room temperature, about 50 minutes. Refrigerate until completely chilled, 8 hours to overnight.
Step 7
To make the frosting, beat confectioners' sugar, cream cheese, and almond extract in a medium bowl with an electric mixer until smooth.
Step 8
Remove the ring of the pan and spread the frosting on top of the chilled cheesecake layer.
