Preheat the Blackstone to medium-low heat and oil the griddle's surface with vegetable oil or cooking spray.
In a large bowl, whisk together the flour, sugar, and baking powder.
Pour in the milk, butter, vegetable oil, and vanilla. Whisk to combine.
Whisk in the eggs until a well-combined, smooth batter forms. A few small lumps are okay.
Pour 1/4 cup of batter per pancake onto the Blackstone. Cook until bubbles appear and the edges of the pancake no longer look shiny and wet. This will take about 2 minutes.
Flip the pancake and cook for an additional 1-2 minutes. When done, the pancake should be golden brown and the center should be firm to the touch.
Serve the pancakes warm with your choice of fruit, maple syrup, and whipped cream for topping.
