This baked Chocolate Ricotta Cheesecake is deliciously creamy, light and moderately sweet. It's a healthier chocolate cheesecake with just the right amount of chocolate flavour, easy to make, perfect for any occasion.
Preheat the oven to 375 F/190 C/gas mark 5. Line the bottom of your pan with parchment and lock the sides. Set aside.
Prepare crustingredients: Place the biscuits in a food processor and pulse until they have the texture of fine crumbs (or use ready-made graham crumbs). Alternatively, place the biscuits in a plastic bag and crush with a rolling pin.
Combine crust ingredients: To a bowl add the crumb mixture, melted butter and 1 tablespoon of cocoa. Stir until thoroughly combined.
Make cheesecake base: Cover the bottom of your pan with the crumb mixture pressing down a little (you can smooth out the top using the bottom of a glass).
Bake base: Bake in the centre of the oven for 15 minutes. Remove from the oven and set aside to cool. Increase the heat to 400 F/ 200 C/190 C fan/ gas mark 6. In the meantime prepare the chocolate cheesecake filling.
Cheesecake filling
Melt chocolate: add pieces of chocolate to a glass bowl and place over a pot of gently simmering water, stirring occasionally. Remove the bowl from the pot when almost all the chocolate has melted (it will finish melting as you stir). Alternatively melt the chocolate in the microwave. Set aside while you prepare the rest of the ingredients.
Beat cheese: Combine the ricotta with the cream cheese and beat (using the paddle attachment) on med-low speed gradually adding in the sugar until the mixture is smooth and creamy (1-2 minutes). Scrape the sides and bottom of the bowl often.
Add cocoa: Add the cornflour, cocoa and vanilla extract and beat only until just combined.
Add chocolate: Pour in the melted chocolate (make sure it’s cooled) and continue beating just to combine.
Add eggs: Add the eggs one by one beating on low speed just until combined (do NOT overbeat the mixture at this point).
Add sour cream: Add the sour cream just until combined (as above).
Assemble
Bake cheesecake: Brush the inside of the pan ring (ensure it's cooled completely) with a little melted butter and pour in the cheesecake filling. Tap gently against the counter to remove any air bubbles, smooth out the top and place in the centre of the preheated oven. Bake for 10 minutes then lower the temperature to 245-250 F/120 C/110 C fan. (If, like me, you are using a gas oven set the temperature to halfway between 'S' and 0 ensuring your oven doesn't switch off completely) Continue baking for 45 minutes then switch the oven off and leave the cheesecake inside for an hour (but do NOT open the oven door).
Cool cheesecake: Open the oven door a little, wait for about 15 minutes then remove the cheesecake and leave to cool completely. It will still be a little wobbly but that's ok. Once cooled cover and refrigerate it (without removing the pan ring) for at least 6 hours before serving.
Serve: Run a thin spatula around the cheesecake before carefully removing the pan ring. Decorate with chocolate shavings, fresh berries, whipped cream or fruit compote and enjoy!
Notes
*Remove excess moisture from the ricotta before using. If it's very watery place it in a strainer for a few hours (you may need to do this if using ricotta in the US).
Ensure your ingredients are at room temperature.
Scrape the sides and bottom of the bowl often as you combine the ingredients to ensure they are evenly distributed throughout the filling mixture.
Bake the cheesecake in a preheated oven and do NOT open the oven door while it's baking and for an hour afterwards.
When melting the chocolate remove it from the saucepan when it's almost melted. It will melt completely as you stir it.
Wait for the melted chocolate to cool before adding into the cheesecake batter.
Keep refrigerated, covered, for up to 3 days. This ricotta cheesecake will set as it cools and after about 2 days will become slightly denser, though it'll still be creamy and delicious.
Best served at room temperature.
Freeze for up to 3 months. Remove any toppings, if present, and place the cheesecake in the freezer (without the pan ring) for 3 hours. Remove the bottom of the pan, if present, and place the cheesecake in a large container, or double-wrap in plastic or foil before returning to the freezer.
