In a large bowl, combine flour, baking powder, salt, and sugar.
Mix well until all dry ingredients are combined.
In a separate bowl, whisk together the egg, milk, melted butter, and vanilla extract.
Gently fold the wet ingredients into the dry mixture.
Add the sliced strawberries and bananas to the batter.
Stir gently to evenly distribute the fruit without overmixing.
Preheat a non-stick griddle over medium heat and lightly grease with butter or oil.
Pour about 1/4 cup of batter for each pancake onto the griddle.
Cook pancakes until bubbles form on the surface, then flip and cook until golden brown.
This usually takes about 2-3 minutes per side.
