In a large mixing bowl, whisk together the mashed ripe banana, buttermilk, egg, and vegetable oil until well combined. The mixture should be smooth and slightly chunky from the bananas.
In a separate bowl, whisk together the all-purpose flour, brown sugar, baking powder, baking soda, and salt.
Slowly pour the dry ingredients into the wet mixture. Gently fold the ingredients together using a spatula until just combined. Be careful not to overmix; it’s okay if there are a few lumps.
If using, fold in the toasted pecans until they are evenly distributed throughout the batter.
Preheat your non-stick skillet or griddle over medium heat. Lightly grease it with a little oil or cooking spray to prevent sticking.
Pour about ¼ cup of batter onto the skillet for each pancake. Cook for about 2-3 minutes, or until bubbles form on the surface and the edges appear set. Flip and cook for another 1-2 minutes until golden brown.
Remove the pancakes from the skillet and keep them warm in a low oven while you cook the remaining batter. Serve your Banana Pecan Pancakes warm with maple syrup, sliced bananas, or a sprinkle of extra pecans.
