01 - Preheat the oven to 350°F. Grease an 8-inch round or square baking dish and line with parchment paper if desired.
02 - In a large mixing bowl, combine the cottage cheese, Greek yogurt, sugar, lemon zest, lemon juice, vanilla extract, and salt. Mix well until smooth. For a creamier texture, blend with an immersion blender.
03 - Add the eggs one at a time, mixing thoroughly after each addition.
04 - Sprinkle in the cornstarch and stir until fully incorporated.
05 - Gently fold in the raspberries, being careful not to crush them.
06 - Pour the batter into the prepared baking dish and smooth the top.
07 - Bake for 38–42 minutes, or until the center is set and the edges are lightly golden.
08 - Let cool to room temperature, then chill in the refrigerator for at least 2 hours before slicing.
09 - Serve cold or at room temperature, garnished with extra raspberries and a dusting of powdered sugar if desired.
