1. Preheat Your Oven
Start by preheating your oven to 350°F (175°C). This temperature is perfect for getting that golden-brown finish on your pies while ensuring they cook evenly.

2. Grease the Muffin Tin
Grease a 12-cup muffin tin well with butter or cooking spray to prevent the pies from sticking. If you’re worried about cleanup, consider lining the tin with muffin liners.

3. Mix the Ingredients
In a large bowl, whisk the eggs and sugar until smooth and well-combined. This will create the base for your pie’s creamy texture. Then, add the flour, melted butter, milk, lemon juice, lemon zest, and vanilla extract. Continue whisking until everything is fully incorporated and there are no lumps.

4. Pour into Muffin Tin
Pour the prepared batter evenly into each muffin cup. You want each cup to be filled about 3/4 full, so each pie has room to rise and bake.

5. Bake the Pies
Place your muffin tin in the oven and bake for 35-40 minutes or until the pies are lightly golden and set in the center. The edges should be slightly puffed, while the centers remain soft but firm. If you gently touch the top, it should bounce back without leaving an indent.

6. Cool and Dust
After baking, remove the pies from the oven and allow them to cool completely in the tin. This cooling period allows the pies to set further. Once cooled, dust them lightly with powdered sugar for an extra touch of sweetness and elegance.
