01 - Whisk together rolled oats, all-purpose flour, brown sugar, baking powder, baking soda, and salt in a large mixing bowl.
02 - In a separate bowl, whisk together milk, eggs, creamy peanut butter, maple syrup, melted unsalted butter, and vanilla extract until smooth.
03 - Pour wet mixture into dry ingredients and stir gently until just combined, leaving some lumps in the batter.
04 - Allow the batter to rest for 5 minutes to soften the oats.
05 - Heat a nonstick skillet or griddle over medium heat and lightly brush with melted butter.
06 - Pour approximately 1/4 cup of batter onto the skillet for each pancake. Cook until bubbles form on the surface and edges begin to set, about 2–3 minutes.
07 - Flip pancakes and continue cooking for 1–2 minutes until golden brown and thoroughly cooked.
08 - Repeat with remaining batter, adding additional butter to the skillet as needed.
09 - Serve pancakes warm topped with sliced bananas, chopped roasted peanuts, and a drizzle of maple syrup.
