01 - Preheat oven to 350°F. Grease an 8-inch round or square baking dish with butter or cooking spray. Line with parchment paper for easy removal if desired.
02 - In a large mixing bowl, combine cottage cheese, Greek yogurt, sugar, lemon zest, lemon juice, vanilla extract, and salt. Mix thoroughly until smooth. For an ultra-creamy texture, use an immersion blender to eliminate any cottage cheese lumps.
03 - Add eggs one at a time, mixing well after each addition to ensure proper emulsification.
04 - Sprinkle cornstarch over the mixture and stir until completely dissolved and no dry pockets remain.
05 - Gently fold in fresh raspberries using a spatula, taking care not to crush or mash the delicate fruit.
06 - Pour batter into prepared baking dish and smooth the top with a spatula for even baking.
07 - Bake for 38-42 minutes until the center is set and edges are lightly golden brown. The center should still have a slight jiggle but not be liquid.
08 - Let cool to room temperature, then refrigerate for at least 2 hours to allow the bake to set completely and develop proper texture.
09 - Slice into squares and serve chilled or at room temperature. Garnish with additional fresh raspberries and a light dusting of powdered sugar if desired.
