Whisk the flour, sugar, baking powder, and salt in a large bowl.
Whisk the milk, eggs, melted butter, and vanilla in a second bowl. Pour over the dry mixture and stir just until combined. Rest the batter 5 to 10 minutes.
Heat a nonstick skillet over medium heat and brush with butter. Pour about ⅓ cup batter per pancake. Cook 2 to 3 minutes until bubbles form and edges set, flip, and cook 1 to 2 minutes more. Make 8 pancakes of similar size.
Cool the pancakes completely on a wire rack.
Beat the cold cream, powdered sugar, and vanilla to medium peaks. Pat the sliced strawberries dry.
Stack one pancake on a plate, spread with about ⅓ cup cream, and add strawberries. Repeat with the remaining pancakes, finishing with cream and berries.
Refrigerate 20 to 30 minutes, then slice with a sharp knife, wiping the blade between cuts.
