In a blender or food processor, combine the cottage cheese, eggs, oat flour, baking powder, cinnamon, vanilla, maple syrup, and sea salt.
Process on high speed for 30 to 45 seconds until the batter is completely smooth and slightly aerated.
Lightly grease a large microwave-safe mug or a small deep bowl with a touch of coconut oil or avocado oil spray.
Pour the blended batter into the prepared mug, ensuring it does not fill more than three-quarters of the container to allow for rising.
Sprinkle the chopped pecans evenly over the top of the batter.
Microwave on high for 2 minutes and 30 seconds, or until the center is firm to the touch and the bread has pulled away slightly from the sides.
Allow the bread to rest and cool for at least 1 minute before enjoying it directly from the mug or inverted onto a plate.
