Preheat your oven to 425ºF (220ºC) with a 12-cup muffin pan placed on the middle rack.

In a mixing bowl, combine flour, milk, eggs, sugar, vanilla extract, and salt. Blend until smooth and let rest for 10 minutes.

Cut the unsalted butter into 12 equal chunks and distribute one piece into each well of the preheated muffin pan.

Pour about 1/3 cup of the rested batter into each well of the muffin pan.

Bake for 12-15 minutes without opening the oven door.

Carefully remove from the oven and let cool for about a minute before serving. Dust with powdered sugar and add toppings.

Serve warm and pair with crispy bacon, Greek yogurt, or fresh fruit.
