Blueberry Buttermilk Pancake

Wanted to use the buttermilk before it expires, so made some pancake for breakfast. I use frozen blueberries as I always keep some in the freezer just in case I need it. Picture is abit ugly but taste was ok...
Ingredients:

1 cup plain flour
2 tbsp sugar
1 ¼ tsp baking powder
¼ tsp baking soda
¼ tsp salt
1 cup buttermilk
1 large egg
3 tbsp melted unsalted butter
125gm of blueberry

Maple syrup, honey, or jam and butter

Method:
1. In a medium bowl, sift together the flour, baking powder, baking soda, and salt. Mix well. In another bowl, whisk together the buttermilk, egg, and melted butter to blend thoroughly. Pour the liquid ingredients over the dry ingredients and mix with the whisk till everything is just combined. Add in blueberry and mix till combined.
2. Heat up a frying pan, lightly oil the pan, spoon ¼ cup of batter onto pan, allowing space for the spreading. When the undersides of the pancakes are golden and the tops are lightly speckled with bubbles, flip the pan cakes over and cook until the other sides are lightly brown. Serve warm with maple syrup and butter or as desire.
