In a large bowl, sift together 1 1/2 cups flour, 3 1/2 teaspoons baking powder, 1 teaspoon salt, 1 Tablespoon sugar, 1 teaspoon cinnamon and 1/4 teaspoon nutmeg.
Make a well in the center of the dry ingredients and pour in 1 1/4 cup milk, 1 egg and 1 teaspoon vanilla and mix well with a whisk.
In a microwavable safe measuring cup, melt the 3 Tablespoons butter, and then let it sit to cool before adding to the batter. Do not add warm butter with the eggs as it can cause the eggs to cook before you want them to.
Spray a baking sheet with non-stick spray and then set aside and preheat the oven to 350 degrees Fahrenheit.
Spread the pancake batter onto the prepared baking sheet and then spread it out in an even layer with a spatula.
Place the sheet into the preheated oven and bake until browned and a toothpick inserted in the center comes out clean, around 10-15 minutes.
Finally, cut the Sheet-Pan Pancakes and serve with dinner and enjoy!
