Whisk together the dry ingredients in a bowl (flour, sugar, baking powder, baking soda, salt). In a separate bowl, whisk the egg, buttermilk, vanilla, and melted butter. Add into the dry ingredients and whisk until just combined. Avoid over-mixing the batter.
Heat a nonstick pan over medium heat and melt some butter.
Pour even amounts of batter into the hot skillet and spread it flat.
Arrange a few blueberries on top. Cook until you see bubbles on top and the edges firm up. Flip and cook for another 1-2 minutes until pancakes are fluffy and cooked through.
Serve with butter and maple syrup. Enjoy!
Notes
Avoid over-mixing the batter to prevent tough pancakes. Stir until just combined for a fluffy texture.
For even cooking, use a nonstick pan or griddle. If using a skillet, coat the surface with butter or oil.
Watch for bubbles and firm edges to know when to flip the pancakes.
