Combine Dry Ingredients: In a large bowl, mix the flour, sugar, salt, baking powder, and chia seeds.
Prepare Wet Ingredients:
In a separate bowl, lightly whisk together the eggs, buttermilk, and vanilla extract.
Stir in the melted and cooled butter. (Don’t worry if small lumps start to form.)
Mix the Batter: Gently fold the wet mixture into the dry ingredients using a spatula. Be careful not to overmix; a few lumps are fine. If desired, fold in the blueberries at this stage.
Rest the Batter: Let the batter sit for 10 minutes to allow it to thicken slightly.
Heat the Pan: Preheat a skillet or griddle over medium heat.
Grease the Surface: Lightly grease the pan with butter or oil.
Cook the Pancakes: Pour about 1 ½ tablespoons of batter onto the griddle for each pancake.
Flip: Cook until bubbles appear on the surface, then flip and continue cooking until the pancakes are golden brown on both sides.
Serve: Enjoy the pancakes immediately with butter, maple syrup, or your favorite toppings.
