In a mixing bowl, combine the all-purpose flour, 3 tablespoons sugar, salt, baking soda, and baking powder. Mix well until all the dry ingredients are evenly incorporated.
In a separate bowl, mix the diced strawberries with the remaining 5 tablespoons sugar to release their juices. Set aside for a few minutes.
Add the melted butter and eggs to the dry ingredients and mix until well combined. Gradually pour in the whole milk while stirring the batter. Mix until smooth and no lumps remain.
Gently fold in the strawberry mixture into the pancake batter.
Heat a skillet or griddle over medium heat. Once the skillet is hot, ladle approximately 1/3 cup of the pancake batter onto the skillet for each pancake.
Cook until bubbles form on the surface of the pancake, then flip and cook for another minute or until golden brown. Repeat the process with the remaining batter, adjusting the heat if necessary to prevent burning.
Serve the pancakes warm with your favorite toppings such as maple syrup, whipped cream, or additional diced strawberries.
