Method
Preheat and prepare the pan
- Preheat oven to 350F, and grease a 9x5 loaf pan.
- Whisk flour, baking powder, baking soda, salt, cinnamon, and nutmeg together.
Mix wet ingredients
- In a large bowl, whisk eggs, both sugars, oil, sour cream, and vanilla until smooth.
Combine and form the swirl
- Fold flour mixture into the wet ingredients until just combined, then fold in diced apples.
- Pour half the batter into the prepared pan and spread it into an even layer.
- Mix the cinnamon-sugar swirl and sprinkle half over the batter.
- Pour remaining batter over the swirl and spread to cover.
- Top with remaining cinnamon sugar.
- Run a knife through the batter once to create a subtle swirl.
Bake and cool
- Bake 55-65 minutes until a toothpick inserted in the center comes out clean.
- Cool in the pan 15 minutes before slicing.
Notes
Pro tip: fold until the batter is just combined to keep the crumb tender, then create the swirl with only one gentle knife pass. Store the sliced loaf in an airtight container at room temperature for up to 2 days or refrigerate up to 5 days; reheat briefly. Freezing is yes—wrap tightly and freeze up to 2 months. For a lighter swap, use low-fat sour cream (it keeps the same moisture without changing the method).
