Preheat your oven to 375°F (190°C) and line a 12-cup muffin tin with paper liners or grease lightly.
Step 2: Mix Dry Ingredients
In a large bowl, combine flour, sugar, salt, baking powder, and poppy seeds. Stir until well blended.
Step 3: Mix Wet Ingredients
In a separate bowl, whisk together milk, oil (or melted butter), eggs, lemon zest, lemon juice, and vanilla extract.
Step 4: Combine
Pour the wet ingredients into the dry ingredients and gently fold together until just combined. Do not overmix — a few lumps are okay.
Step 5: Fill Muffin Tin
