Crisp puff pastry sheets sandwich a chicken and mushroom filling with sour cream and grated cheese. Bake pastry fully and let it cool before layering so the cream does not run. The assembled savoury cake needs a short chill to slice cleanly. Cook chicken through before mixing it into the filling and keep the finished layers refrigerated. Heat oven to 200°C (390°F). Divide pastry into four thin rectangles and bake 15 to 20 minutes until crisp; cool. Cook chopped onion and mushrooms in oil until moisture evaporates; add diced chicken and cook to 74°C (165°F), then garlic. Stir sour cream with mayonnaise and pepper; cool filling fully. Spread cream thinly on each pastry layer and divide chicken mixture and cheese between layers; stack.
