Combine Ingredients: In a large bowl, mix together the pancake mix and buttermilk until just combined.

Add Egg: Crack the egg into the mixture and stir gently until blended.

Melt Butter: Pour in the melted butter and add the vanilla extract. Mix until everything is well combined but don’t overmix; a few lumps are okay.

Heat the Pan: Preheat a non-stick skillet or griddle over medium heat.

Pour Batter: Pour about 1/4 cup of batter onto the hot skillet for each pancake.

Cook: Cook until bubbles form on the surface, then flip and cook for another 1-2 minutes until golden brown.

Serve Warm: Stack the pancakes on a plate and serve with your favorite toppings like syrup, fruit, or whipped cream.
