Method
Prep and preheat
- Preheat oven to 350F, and grease and line a 9x5-inch loaf pan.
Make cinnamon sugar and apple filling
- Mix brown sugar and ground cinnamon, then toss the chopped apples with 2 tablespoons of the mixture until coated.
Mix wet batter
- Beat softened butter and granulated sugar until fluffy, then beat in the eggs and vanilla extract until smooth.
Combine dry and wet ingredients
- Whisk all-purpose flour, baking powder, and salt together, then add to the batter alternately with milk until just combined.
Layer and swirl
- Spread half the batter in the loaf pan.
Add first apple and cinnamon layer
- Top with half the apples and half of the remaining cinnamon sugar mixture.
Add second batter and apples
- Repeat the layers with the remaining batter, apples, and cinnamon sugar.
Swirl for fritter effect
- Swirl gently with a knife to create marbled cinnamon-brown sugar streaks on top and through the loaf.
Bake
- Bake 50-55 minutes at 350F until a toothpick comes out clean.
Glaze and serve
- Cool the loaf for 15 minutes.
Make and drizzle the vanilla glaze
- Whisk powdered sugar with 2-3 tablespoons of milk until thick, then drizzle over the warm loaf.
Notes
Pro tip: To keep the swirl distinct, toss the apples right before layering and swirl lightly—overmixing makes the cinnamon sugar blend into the batter. Store covered at room temperature up to 2 days or refrigerate up to 5 days; freeze slices up to 2 months (glaze after thawing for best texture). For a lighter version, use half butter (or plant-based butter) and replace half the granulated sugar with an equal amount of coconut sugar for similar sweetness.
