Let’s set the stage for success. Preheat your oven to 425°F (220°C). This temperature is vital for that perfect fluffy texture.

Grab your favorite rimmed baking sheet (a sheet pan around 18x13 inches works perfectly). Coat it generously with cooking spray or brush it with melted butter. We want those pancakes to slide out easily when they’re done.

In a large bowl, combine the flour, baking powder, sugar, salt, cinnamon, and lemon zest. Whisk them together until evenly mixed. This is the base of your pancakes.

In another bowl, whisk together the eggs, milk, melted butter, and vanilla extract. Ensure everything is combined well. It’s important because these elements bring moisture and flavor to your pancakes.

Now it’s time for the magic to happen! Pour the wet mixture into the dry ingredients. Stir gently until just combined. Don't overmix! A few lumps are perfectly okay.

Pour the batter into the prepared baking sheet, spreading it evenly. Slide the pan into your preheated oven and bake for about 20-25 minutes. You’ll know it's done when the edges are golden brown and a toothpick inserted comes out clean.

Once the pancake is baked, take it out and let it cool for a few minutes. Cut it into squares, and serve with your favorite toppings. Maple syrup, fresh fruit, whipped cream—just go wild with it!
