In a large mixing bowl, combine the flour, baking powder, sugar, and salt. Whisk them gently to ensure the ingredients are evenly distributed and aerated.
Melt the butter until fully liquefied. Using a microwave-safe jug large enough to accommodate the wet ingredients streamlines the process and reduces extra cleanup.
Whisk together the melted butter, egg, vanilla essence, and milk until the mixture is smooth and cohesive. Gradually pour the wet ingredients into the bowl of dry ingredients, whisking just until combined. A few small lumps are completely fine and contribute to the pancakes’ tender texture.
Let the batter rest for about 10 minutes; this allows the flour to fully hydrate and ensures fluffier pancakes.
Meanwhile, hull the strawberries and dice them into small, 1 cm cubes, removing any leafy tops. Gently fold the diced strawberries into the rested batter, being careful not to overmix.
