Preheat oven to 325°F (175°C). Line a muffin tin with paper liners or grease well.
Blend wet base: In a medium bowl, whisk together eggs, cottage cheese, vanilla, and honey until smooth. (For an extra fluffy texture, blend in a blender or food processor.)
Add dry ingredients: Stir in coconut flour, flaxseed or psyllium husk, and baking powder until fully incorporated. The batter will thicken slightly.
Fold in mix-ins: Gently stir in blueberries and pecans.
Divide batter evenly among muffin cups.
Bake for 20-35 minutes, until the tops are golden and a toothpick inserted in the center comes out mostly clean.
Cool completely on a wire rack before removing from liners (they firm up as they cool).
