Preheat your oven to 375°F (190°C) and line a muffin tin with paper liners.
Sift together the flour, baking powder, and salt in a large bowl. In a separate bowl, beat the eggs with the coconut oil (or your chosen alternative), sugar, and yogurt until well blended.
Gently fold the dry ingredients into the wet mixture using a spatula. Carefully stir in the mixed berries, taking care not to break them apart.
Distribute the batter evenly into the muffin cups. Top each muffin with a light dusting of extra sugar to create that irresistible sugary crisp.
Bake for 20-25 minutes or until a toothpick inserted in the center comes out clean and the tops are beautifully golden.
Optional: For an extra indulgence, blend 1/4 cup honey with 1/4 cup softened salted butter. Once the muffins are out of the oven and still warm, spread this honey butter gently over each muffin for an elevated flavor experience.
