Preheat your oven to 400°F (200°C) and place a muffin tin inside to heat for at least 10 minutes.

In a mixing bowl, combine all-purpose flour, milk, large eggs, sugar, vanilla extract, and salt. Mix until smooth, about 1-2 minutes.

Remove the hot muffin tin and add ½ tablespoon of butter to each cup, allowing it to melt.

Pour batter into each muffin cup, filling about ¾ full, and add spices if desired.

Bake for 15-20 minutes until puffed up and golden brown.

Let cool for a minute before serving warm with desired toppings.
