Preheat your oven to 350°F (175°C) and grease a 24-cup mini muffin pan.
In a blender or food processor, combine the cottage cheese, oats, egg, honey, vanilla, lemon zest, baking powder, and salt. Pulse until the oats are broken down and the mixture is well-combined.
Pour the batter into a bowl and gently fold in the blueberries.
Let the batter rest for 5 minutes to thicken slightly.
Divide the batter among the prepared mini muffin cups, filling each about 3/4 full.
Bake for 18-22 minutes, or until the bites are firm to the touch and lightly golden.
Allow them to cool in the pan for a few minutes before transferring to a wire rack to cool completely.
Notes
Store in the fridge for 5 days or freeze for 2 months. Warm for 10-15 seconds in the microwave for best texture.
