This Creamy Polish Sernik Is the Ultimate Melt-in-Your-Mouth Dessert
A super smooth and velvety baked treat that comes together with zero fuss.
If you love rich, vanilla-infused desserts but want something completely foolproof, this traditional Polish cheesecake is an absolute must-try. The trick is simply blending the curd cheese until it is perfectly silky, giving you a cloud-like texture that literally melts in your mouth.
Here’s what you need: 1.5 pounds of full-fat curd cheese or cottage cheese (9% fat), 4 large eggs, ¾ cup of sugar, 7 tablespoons of unsalted butter (softened), ½ cup of sour cream, 4 tablespoons of cornstarch, 2 teaspoons of vanilla sugar (or vanilla extract), and the finely grated zest of half a lemon (optional).
To start, place your softened butter and sugar into a mixing bowl and whip them together until the mixture is light, pale, and fluffy. Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next, then gently whisk in the sour cream, vanilla sugar, and cornstarch.
To achieve that signature silkiness, pass your curd cheese through a fine-mesh sieve twice or blitz it thoroughly with an immersion blender until it is completely uniform, smooth, and entirely free of any graininess.
Combine the whipped egg mixture with the smooth cheese base, tossing in the fresh lemon zest if you want a bright hint of citrus. Give the batter a final, gentle fold until it is perfectly homogenous, then pour it into a baking pan lined neatly with parchment paper.
Slide the pan into the oven and bake at 165°C for about 60 minutes until the edges are set but the center still has a slight, delicate jiggle. Once the timer goes off, turn off the heat, crack the oven door open just an inch, and leave the cake to rest inside for another 30 minutes to cool down slowly and keep it from sinking.
While you can technically slice into it once it reaches room temperature, the real magic happens if you let it chill in the refrigerator for at least 6 hours. This patience rewards you with a dense, fudgy, and ultra-creamy texture that holds its shape beautifully on the plate.
