Preheat your oven to 375°F (190°C) and line a standard 12-cup muffin tin with paper liners or lightly grease the cups.
In a large mixing bowl, combine the rolled oats, all-purpose flour, baking powder, baking soda, salt, cinnamon, and brown sugar. Stir until evenly mixed.
In a separate bowl, whisk together the egg, peanut butter, milk, vanilla extract, and neutral oil until smooth and well combined.
Slowly pour the wet ingredients into the bowl with the dry ingredients. Use a spatula or wooden spoon to mix until just combined. Be careful not to overmix; a few lumps are okay.
If desired, fold in chocolate chips or raisins to add a touch of sweetness or texture.
Divide the batter evenly among the 12 muffin cups, filling each about three-quarters full.
Bake in the preheated oven for 16-18 minutes, or until a toothpick inserted into the center of a muffin comes out clean.
Remove the muffins from the oven and let them cool in the tin for 5 minutes before transferring to a wire rack to cool completely.
Serve warm or at room temperature. Store leftovers in an airtight container at room temperature for up to 3 days or refrigerate for up to a week. These muffins can also be frozen for up to 3 months.
