Ingredients
  

  • 1 cup all-purpose flour (or oat flour) 125 g
  • ½ cup protein powder (whey or plant-based) 50–60 g
  • ¼ cup unsweetened cocoa powder 25 g
  • ½ cup granulated sugar (or ⅓ cup honey/maple syrup) 100 g
  • 2 tsp baking powder
  • ¼ tsp baking soda
  • ¼ tsp salt
  • 2 large eggs
  • ¾ cup milk (dairy or plant-based) 180 ml
  • ½ cup Greek yogurt or dairy-free yogurt 120 g
  • cup neutral oil 80 ml
  • 1 tsp vanilla extract
  • ½ cup chocolate chips Optional

Instructions
 

  • Preheat Oven and Line Tin:

    Heat the oven to 350°F (175°C) and place paper liners in a muffin tin.
  • Whisk Dry Ingredients Together:

    In a large mixing bowl, combine flour, protein powder, cocoa powder, sugar (or honey/maple syrup), baking powder, baking soda, and salt with a whisk.
  • Beat Wet Ingredients Separately:

    In a separate bowl, beat eggs, milk, yogurt, oil, vanilla, and sweetener (add honey/maple syrup here if using).
  • Fold Wet into Dry Mixture:

    Pour the wet mixture into the dry and fold gently until just incorporated; avoid overmixing. Add chocolate chips at this point if desired.
  • Fill Muffin Cups Evenly:

    Distribute the batter evenly among the muffin cups, filling each to about three-quarters full.
  • Bake Until Firm and Bouncy:

    Bake for 18–22 minutes, until the tops feel firm and bounce back when lightly pressed.
  • Cool and Serve Muffins:

    Let the muffins cool in the pan for 5 minutes, then move them to a wire rack to finish cooling. Serve and enjoy.
