Preheat your oven to 400°F (200°C) and line a 12-cup muffin tin with muffin liners or grease it well.
In a large bowl, whisk together 2 cups whole wheat flour, ¼ teaspoon table salt, 2 teaspoons baking powder, and ½ teaspoon baking soda until well combined.
Add the 1 ½ cups blueberries to the flour mixture and toss gently to coat them in flour.
In a separate small bowl, whisk together 2 large eggs, 1 teaspoon pure vanilla extract, ½ cup melted and cooled coconut oil, ½ cup pure maple syrup, and 1 cup unsweetened applesauce until smooth.
Make a well in the center of the dry ingredients and pour in the wet ingredients.
Gently fold the wet and dry ingredients together until just combined.
Scoop about ¼ cup of the batter into each prepared muffin cup.
Bake in the preheated oven for 14 to 17 minutes, or until the muffins are set and a toothpick comes out clean.
Once done, cool the muffins in the tin for about 10 to 20 minutes, then transfer them to a cooling rack.
Enjoy your Whole Wheat Blueberry Muffins warm or allow them to cool completely before storing.
