Preheat your oven to 350°F and lightly grease a baking dish.
Whisk together the eggs, cottage cheese, honey, and vanilla until smooth.
Stir in the oats, baking powder, and salt.
Fold in the blueberries gently so they don’t all burst before baking.
Pour the mixture into the prepared dish and spread evenly.
Bake for 35 to 40 minutes until set and lightly golden on top.
Cool for a few minutes before slicing. Serve warm or chilled.
