Ingredients
  

  • 1 ½ cup whole wheat flour 180 g, spooned and leveled
  • ¾ cup rolled oats 68 g
  • 1 tsp baking powder
  • ½ tsp baking soda
  • 1 tsp salt
  • 2 tsp cinnamon
  • 6 Tbsp unsalted butter 85 g, melted and cooled to room temperature
  • ½ cup maple syrup 170 g
  • ½ cup unsweetened applesauce 120 g
  • ½ cup plain Greek yogurt 120 g
  • 2 tsp vanilla extract
  • 2 large eggs
  • 1 cup finely chopped apple about 1 small apple with skin on, 150 g

Instructions
 

  • Preheat Oven and Prep Pan:

    Set the oven rack to the middle position and preheat to 350°F (175°C). Prepare a 12-cup muffin tin by lining it with paper or silicone liners.
  • Whisk Dry Ingredients:

    In a large bowl, combine the flour, oats, baking powder, baking soda, salt, and cinnamon, whisking until evenly mixed.
  • Mix Wet Ingredients:

    In another large bowl, whisk the melted butter, maple syrup, applesauce, Greek yogurt, vanilla, and eggs together until the mixture is smooth.
  • Combine Wet and Dry:

    Pour the dry ingredients and the chopped apple into the wet mixture. Stir with a large wooden spoon or spatula only until incorporated; avoid overmixing.
  • Fill Muffin Cups:

    Divide the batter evenly among the prepared muffin cups (a 3-tablespoon cookie scoop works well for this).
  • Bake Until Golden:

    Bake for 18–22 minutes, until the tops are firm and a toothpick inserted into the center comes out mostly clean. Be careful not to overbake, or the muffins will become dry.
  • Cool in Pan Then Rack:

    Allow the muffins to rest in the pan for 5 minutes, then move them to a wire rack to reach room temperature before serving.
