Method
Prep the pan and oven
- Preheat oven to 350F and grease and line a 9x5-inch loaf pan with parchment paper if needed.
Make cinnamon sugar and prepare apples
- Mix brown sugar and ground cinnamon, then toss the chopped apples in 2 tablespoons of the mixture.
Make the batter
- Beat the softened butter and granulated sugar until fluffy, about 2 minutes.
- Beat in the eggs one at a time, then mix in the vanilla extract.
- Whisk the all-purpose flour, baking powder, and salt, then add to the batter alternately with the milk until just combined.
Layer and swirl
- Spread half the batter into the loaf pan and top with half the cinnamon apples and half of the remaining cinnamon sugar.
- Spread the remaining batter over the first layer, then add the remaining apples and remaining cinnamon sugar.
- Swirl gently through the batter with a knife to create ribbon-like cinnamon streaks.
Bake
- Bake at 350F for 50-55 minutes, until a toothpick inserted in the center comes out clean.
Glaze and cool
- Cool the loaf in the pan for 15 minutes before glazing.
- Whisk powdered sugar with 2-3 tablespoons milk until smooth, then drizzle the glaze over the warm loaf.
Notes
For the best swirls, toss the apples with the cinnamon sugar right before layering so they don’t release excess liquid. Store in an airtight container at room temperature up to 2 days or refrigerate up to 5 days; rewarm slices briefly in the oven if you like. Freezing is yes—wrap tightly and freeze up to 2 months, then thaw overnight in the fridge. For a lighter option, use half the butter and replace with an equal amount of unsweetened applesauce (texture will be slightly softer).
