Preheat oven to 400°F. Slice the butter and add to a 9x13" pan. Then place into the oven until melted (about 2 minutes).
Whisk together the flour, sugar and salt in medium-sized bowl. Add milk and vanilla. Then beat in ONE egg at a time until smooth. For extra fluffy pancakes, beat 30 seconds per egg.
Pour mixture over melted butter and bake 18-20 mins., or until golden brown. Slice and serve warm with your favorite toppings.
Notes
Note: You can also make these in the blender to make it easier. Simply mix up the liquid and eggs first for about 30 seconds. Then add in the dry ingredients. They may not be quite as fluffy, but it works great for when you are in a hurry.Store: Cover and store leftovers in your refrigerator for 2-3 days. Reheat in oven, toaster oven or the microwave.Freeze: Cool completely then cut into serving size pieces. Wrap each individual piece tightly with plastic wrap and store in a freezer safe bag. To reheat, place on a baking sheet and cover with foil and heat in the oven at 350°F until warm.
