Preheat oven to 375°F (190°C). Line a muffin tin with paper liners or grease lightly.
Mix dry ingredients: In a medium bowl, whisk together flour, baking powder, baking soda, and salt.
Mix wet ingredients: In a large bowl, whisk melted butter and honey. Add eggs one at a time, then vanilla, lemon zest, lemon juice, and Greek yogurt.
Combine: Add dry ingredients to wet, mixing just until combined (don’t overmix!). Fold in blueberries and chopped basil gently.
Scoop and top: Divide batter among muffin cups. Sprinkle tops with a pinch of lemon zest if you want.
Bake: 18–22 minutes, or until a toothpick comes out clean and the tops are golden.
Optional Drizzle with honey once cooled.
