Step-by-Step Instructions
-
Prepare the Base: Mix crushed biscuits with melted butter. Press firmly into a parchment-lined square baking pan. Chill in the fridge for 20 minutes.
-
Cream the Cheese: In a large bowl, beat the cream cheese and sugar until smooth and aerated.
-
Incorporate Liquids: Gradually whisk in the heavy cream, vanilla extract, and lemon juice.
-
Add Eggs: Add eggs one at a time, mixing on low speed just until combined. Pro Tip: Do not overbeat here to avoid adding too much air, which causes cracking.
-
Sift in Solids: Gently fold in the cornstarch until no white streaks remain.
-
The Bake: Pour the batter over the crust. Bake at 160°C (320°F) for about 40–50 minutes. The edges should be set and golden, but the center should still have a slight “jiggle.”
-
The Cool Down: Turn off the oven and leave the door slightly ajar for 30 minutes. Then, let it cool completely at room temperature before refrigerating.
Frequently Asked Questions (FAQ)
Q: Why did my cake crack on top? A: Usually, this is caused by over-mixing the eggs or baking at too high a temperature.
Q: Can I use low-fat cream cheese? A: It is not recommended. The texture will be watery and won’t achieve that iconic “creamy” look seen in your photo.
Storage Tips
-
Refrigeration: Store in an airtight container for up to 5 days. It actually tastes better on the second day!
-
Freezing: You can freeze these squares for up to 1 month. Wrap them tightly in plastic wrap and foil. Thaw in the fridge overnight before serving.
Variations
-
Burnt Top Style: Increase the temperature to 200°C for the last 5 minutes for a “Basque” inspired finish.
-
Berry Swirl: Drop small dots of raspberry jam on top before baking and swirl with a toothpick.
-
Chocolate Base: Use Oreo crumbs instead of digestive biscuits for a decadent twist.
How to Serve
For the cleanest slices (like in the picture), use a warm, sharp knife. Dip the knife in hot water and wipe it dry between every single cut. Serve chilled, perhaps with a light dusting of powdered sugar or a few fresh raspberries on the side to complement the tanginess.
