Place the cottage cheese in a deep bowl and add the sugar.
Add the semolina.
Pour in the melted butter, warmed in the microwave or in a small saucepan.
Add the eggs.
Add the sour cream.
Blend everything with an immersion blender or regular blender.
Stop blending when you get a smooth, creamy mixture.
Line a baking pan with parchment paper and spoon in some jam or arrange fruit, chocolate or raisins.
Pour the cottage cheese mixture into the pan.
Smooth the surface evenly with a spoon. Add more jam on top of the mixture.
Bake in a preheated oven at 350°F (180°C) for 30–35 minutes, until a golden crust forms.
Dust the pudding with powdered sugar, if you like, before serving.
