Amelia Grace This is the classic, no-fuss cheesecake built specifically around Philadelphia cream cheese, the sort of recipe that’s been a reliable favourite for decades, and for good reason.
There’s nothing complicated here — a buttery biscuit base, a simple whipped filling, and time in the fridge to set.
It’s the sort of dessert I make when I want something reliably delicious without much effort, and it’s endlessly adaptable with whatever topping you fancy.
Why Philadelphia Specifically Works So Well in This Recipe
Not all cream cheeses behave identically once whipped and set, and Philadelphia has a particular consistency that suits this simple, no-bake style of cheesecake especially well.
Philadelphia has a smooth, dense texture with a reliable fat content that whips up easily without becoming too loose or watery, which matters enormously in a recipe that relies on whipping alone, rather than gelatine or baking, to hold its shape.
Cheaper or lower-fat alternatives can sometimes have a higher water content, resulting in a softer set that doesn’t slice quite as cleanly.
Ingredients for Delia Smith Cheesecake Philadelphia
Biscuit Base:
- 250g digestive biscuits, crushed
- 100g unsalted butter, melted
Filling:
- 600g Philadelphia cream cheese, room temperature
- 100g icing sugar, sifted

To Decorate:
- Fresh berries or a fruit compote, to top (optional)
How to Make Delia Smith Cheesecake Philadelphia — Step by Step
Step 1 — Make the Biscuit Base
Mix the crushed digestive biscuits with the melted butter until fully combined. Press firmly into the base of a 20cm springform tin. Chill for 20 minutes.
Step 2 — Beat the Cream Cheese
Beat the Philadelphia, icing sugar, vanilla extract and lemon zest together until smooth and well combined.
Step 3 — Whip the Cream
In a separate bowl, whip the double cream to soft peaks.
Step 4 — Fold Together
Gently fold the whipped cream into the cream cheese mixture until fully combined and smooth.
Step 5 — Fill the Tin
Pour the filling over the chilled biscuit base, smoothing the top evenly.
Step 6 — Chill
Chill in the fridge for at least 6 hours, ideally overnight, until fully set.
Step 7 — Decorate and Serve
Release from the tin and top with fresh berries or a fruit compote, if using, just before serving.
My Top Tips for the Best Delia Smith Cheesecake Philadelphia
Make sure the Philadelphia is properly at room temperature. Cold cream cheese straight from the fridge is much harder to beat smooth and is more likely to leave lumps in the finished filling.
Whip the cream to soft peaks, not stiff ones. Over-whipped cream can make the filling feel slightly grainy once folded together, so stop as soon as it holds a soft peak.
Give it the full chilling time. This cheesecake relies entirely on chilling to set, since there’s no gelatine or baking involved, so don’t rush this stage.
Press the biscuit base down firmly. A loosely packed base is more likely to crumble apart when you come to slice and serve.
Add toppings just before serving. Fresh fruit especially can release liquid if left sitting on top too long, so add it right before you bring the cheesecake to the table.
Serving Suggestions
Serve chilled, in neat slices, topped with fresh berries or a spoonful of fruit compote. It’s also lovely completely plain, letting the simple, creamy filling speak for itself.
How to Store Delia Smith Cheesecake Philadelphia
In the fridge: Store in an airtight container or covered with cling film for up to 4 days.
At room temperature: Not suitable — this cheesecake needs to stay chilled, both to set and to hold its shape once cut.
In the freezer: Freeze whole or in slices, well wrapped, for up to 2 months. Defrost slowly in the fridge overnight before serving.

Notes
Frequently Asked Questions About Delia Smith Cheesecake Philadelphia
Why hasn’t my cheesecake set properly?
This is usually down to not enough chilling time, since this recipe relies purely on chilling rather than gelatine or baking to firm up. Give it the full 6 hours, ideally overnight.
Can I use a different cream cheese instead of Philadelphia?
You can, though the texture may vary slightly. Philadelphia’s specific consistency is what this recipe is built around, so results with other brands, particularly lower-fat versions, can be a little softer.
Can I make this cheesecake ahead of a dinner party?
Yes, this is an excellent make-ahead dessert — it can be made up to 2 days in advance and kept covered in the fridge until you’re ready to serve.
Why is my filling slightly grainy?
This can happen if the cream was over-whipped before folding in. Whip only to soft peaks, and fold gently rather than stirring vigorously once combined.
