In a mixing bowl, combine the flour, sugar, baking powder, baking soda, and salt. Whisk together until well-mixed.
In a separate bowl, beat the egg and then add milk, melted butter, and vanilla extract. Mix until combined.
Pour the wet ingredients into the dry ingredients and stir gently until just combined (a few lumps are okay).
Preheat a non-stick skillet or griddle over medium heat. Lightly grease the surface if necessary.
Pour about 1/4 cup of batter onto the skillet for each pancake. Cook until bubbles form on the surface (about 2-3 minutes), then flip and cook for another 2 minutes until golden brown. Repeat until all the batter is used.
Allow pancakes to cool slightly before cutting them into quarters.
On each skewer, thread a piece of pancake, a slice of banana, and a half strawberry, alternating until the skewer is filled.
Repeat until all pancakes and fruit are used up.
Serve with maple syrup drizzled over the top or on the side for dipping.
