Creating Lemon Poppy Seed Muffins is straightforward. Follow these steps to ensure delicious results:

1. Preheat the Oven: Set your oven to 375°F (190°C) and line a muffin tin with paper liners.
2. Mix Dry Ingredients: In a large mixing bowl, whisk together the flour, sugar, baking powder, baking soda, and salt until evenly combined.
3. Whisk Wet Ingredients: In another bowl, beat the egg and then add the milk, vegetable oil, lemon zest, and lemon juice. Mix well.
4. Combine Mixtures: Pour the wet ingredients into the dry ingredients and gently fold until just combined. Be careful not to overmix; some lumps are okay.
5. Add Poppy Seeds: Gently fold in the poppy seeds to distribute them evenly throughout the batter.
6. Fill Muffin Cups: Divide the batter evenly among the prepared muffin cups, filling each about 2/3 full.
7. Bake: Place the muffin tin in the preheated oven and bake for 15-20 minutes, or until a toothpick inserted into the center comes out clean.
8. Cool: Remove the muffins from the oven and let them cool in the tin for about 5 minutes. Then transfer them to a wire rack to cool completely.
9. Optional Dusting: If desired, dust the tops with powdered sugar before serving for a lovely presentation.

Following these steps will lead you to perfectly moist and delicious Lemon Poppy Seed Muffins.
