Ingredients
Method
- Preheat oven to 400°F (200°C) and line a 12-cup muffin tin. Whisk together oats, flour, baking powder, baking soda, salt, cinnamon, and nutmeg.
- In a separate bowl, whisk oil, brown sugar, granulated sugar, eggs, buttermilk, and vanilla until smooth.
- Pour wet ingredients into dry and stir gently just until no flour streaks remain.
- Fold in diced apple and optional nuts until evenly distributed.
- Divide batter among muffin cups and bake 18 to 22 minutes until a toothpick comes out clean.
- Cool in the pan 5 minutes, then transfer to a wire rack. Serve warm.
Notes
No buttermilk on hand? Stir 1 tablespoon lemon juice or white vinegar into 1 cup milk and let it sit for 5 minutes. It will do the same job.
