Preheat the Blackstone grill over medium high heat (approximately 400 degrees F).
In a large mixing bowl, whisk together the flour, baking powder, salt and sugar.
Then in a separate bowl, melt the butter and allow it to cool to room temperature. Then mix in the eggs, milk and vanilla extract.
Gradually add the wet ingredients to the dry ingredients and mix until just combined being careful to not over mix the batter. It's ok if there are lumps in the batter.
Place one Tablespoon of butter onto the grill. Let it melt and spread it around with a spatula.
Pour approximately 1/3 cup of the batter onto the hot Blackstone grill. Continue to pour pancakes onto the griddle spacing them a few inches apart until all the batter is used.
Cook the pancakes for 1-2 minutes until bubbles start to appear on the top and the edges are set.
Use a metal spatula to flip the pancakes and cook the opposite side until it's golden brown (1-2 more minutes). Do not press done on the pancakes and do not flip the pancakes multiple times.
Then serve the pancakes warm topped with butter, syrup or any of your other favorite pancake toppings!
