Preheat your oven to 350°F (175°C) and grease a 24-cup mini muffin pan generously.
In a blender or food processor, combine cottage cheese, oats, egg, honey, vanilla, lemon zest, baking powder, and salt. Pulse until oats are broken down and mixture is well-combined.
Pour batter into a bowl and gently fold in blueberries with a spatula, being careful not to break them.
Let the batter rest for 5 minutes to thicken slightly as oats absorb moisture.
Divide batter among the 24 mini muffin cups, filling each about 3/4 full for perfect shape.
Bake for 18-22 minutes, until bites are firm to touch and lightly golden on edges.
Allow bites to cool in pan for 3-4 minutes, then transfer to a wire rack to cool completely.
Notes
Use full-fat cottage cheese for creamiest texture. Old-fashioned rolled oats work best, not quick oats.
Fresh berries are ideal but frozen work if kept frozen. Zest only the yellow part of lemon to avoid bitter pith.
Don’t skip the 5-minute rest as it helps bites hold together. Let cool completely so they set properly.
