Preheat your oven to 375°F and line a muffin tin with paper liners (or grease it well). Grab a large mixing bowl and whisk together flour, sugar, baking powder, baking soda, salt, and poppy seeds. You'll want everything combined before the wet ingredients go in—this prevents lumps and keeps your muffins tender.

In a separate bowl, crack your 2 eggs and whisk them together lightly. Pour in the melted butter and stir until combined. Add the milk, fresh lemon juice, and lemon zest to this mixture, stirring gently after each addition.

Pour the wet ingredients into your dry mixture and fold everything together with a spatula until just barely combined. Don't overmix—I mean it. A few small lumps are totally fine and actually good for texture. Overmixing creates tough, dense muffins.

Divide the batter evenly among your 12 muffin cups, filling each about two-thirds full. You want them uniform so they bake at the same rate. If some cups look way fuller than others, use a spoon to redistribute.

Slide the tin into your preheated 375°F oven and set a timer for 20 minutes. These bake fast, so don't wander off. Around minute 15, you'll start smelling that gorgeous lemon scent drifting through your kitchen.

Your lemon poppy seed muffins recipe is done when a toothpick inserted into the center comes out clean or with just a few moist crumbs. The tops should be golden but not dark brown. If they're pale, give them another 2-3 minutes.

Let the muffins cool in the pan for 5 minutes before turning them out onto a wire rack. This prevents them from sticking but also keeps them from breaking apart. They'll finish cooling on the rack while you make your coffee or tea.
