Preheat the oven to 350°F. Lightly grease a 24-cup mini muffin pan or use a silicone mini muffin pan.
Add the cottage cheese, oats, eggs, baking powder, maple syrup, and vanilla to a blender. Blend until completely smooth. Gently stir in the blueberries.
Divide the batter evenly among the mini muffin cups. Bake for 18–22 minutes, or until the centers are set and the edges are lightly golden.
This part is important: Let the bites cool in the pan for at least 10 minutes before removing them. They’re very soft straight from the oven and will firm up as they cool.
Notes
To refrigerate: Let the bites cool completely, then transfer them to an airtight container. Refrigerate for up to 3–4 days.To freeze: Arrange the cooled bites in a single layer on a parchment-lined baking sheet and freeze until firm. This is how I like to freeze muffins too! Transfer to a freezer-safe bag or container and freeze for up to 2 months for best quality.
