Creating fluffy German pancakes is straightforward if you follow these easy instructions:

1. Preheat Oven: Preheat your oven to 425°F (220°C) and place a large cast-iron skillet or oven-safe baking dish inside to heat up.

2. Mix Eggs: In a large mixing bowl, whisk the eggs until they are light and frothy.

3. Add Milk and Vanilla: Pour in the milk and add the vanilla extract, continuing to whisk until combined.

4. Combine Dry Ingredients: In a separate bowl, combine the flour, sugar, and salt.

5. Mix Wet and Dry: Gradually add the dry ingredients to the egg mixture, whisking gently just until combined. Avoid overmixing; some lumps are fine.

6. Add Butter: Fold in the melted butter until just incorporated.

7. Transfer to Skillet: Carefully remove the hot skillet from the oven. Pour the batter into the skillet, spreading it evenly.

8. Bake: Place the skillet back in the oven and bake for 20-25 minutes until the edges are puffed and golden brown.

9. Serve Immediately: Remove from oven and dust with powdered sugar if desired. Cut into wedges and serve hot.

10. Top It Off: Serve with your choice of fresh fruits or syrup for a delicious finish.

Following these steps will reward you with beautifully fluffy pancakes that everyone will enjoy.
