Step 1: Preheat your oven to 375°F (190°C). Lightly grease an 8x8 inch (20x20 cm) baking dish with cooking spray or butter.
Step 2: In a large bowl, whisk together the cottage cheese, eggs, orange juice, maple syrup, and vanilla extract until well combined and relatively smooth. A few small cottage cheese curds are fine.
Step 3: In a separate medium bowl, combine the rolled oats, ground cinnamon, orange zest, cranberries, and a pinch of salt. Stir to ensure the cranberries are lightly coated.
Step 4: Pour the wet cottage cheese mixture into the dry oat mixture. Stir gently until all ingredients are just combined. Do not overmix.
Step 5: Transfer the mixture into the prepared baking dish, spreading it evenly with a spatula.
Step 6: Bake for 35-40 minutes, or until the top is lightly golden brown and the bake is set in the center. A toothpick inserted into the center should come out mostly clean.
Step 7: Remove from the oven and let it cool for at least 10-15 minutes before slicing and serving. This allows the bake to set properly. Serve warm, optionally with an extra drizzle of maple syrup or a dollop of Greek yogurt.
