In a bowl, mix flour, sugar, baking powder, and salt.
In another bowl, whisk together milk, egg, and melted butter.
Combine wet and dry ingredients until just mixed.
Gently fold in sliced strawberries.
Heat a non-stick skillet over medium heat.
Pour 1/4 cup of batter for each pancake onto the skillet.
Cook until bubbles form on the surface, about 2-3 minutes.
Flip and cook for another 2 minutes until golden brown.
Repeat with remaining batter, adjusting heat as needed.
Serve stacked, topped with whipped cream and extra strawberries.
