Preheat oven to 375°F (190°C) and line a muffin tin with muffin liners.

In a large bowl, whisk together the flour, flaxseed, baking powder, baking soda, cinnamon, and salt.

In a separate bowl, mix together the applesauce, almond milk, honey, coconut oil, and egg until well combined.

Add the wet ingredients to the dry ingredients and stir until just combined.

Fold in the chopped apple.

Divide the batter evenly among the muffin cups, filling each about 2/3 full.

Bake for 18-20 minutes, or until a toothpick inserted into the center of a muffin comes out clean.

Let the muffins cool in the pan for 5 minutes before transferring them to a wire rack to cool completely.

Serve and enjoy your delicious and low calorie Apple Flax Seed Muffins!
