Method
Prep and make spiced filling
- Preheat oven to 350F and grease a 9x5 loaf pan.
- Mix brown sugar, cinnamon, allspice, and cardamom, then toss half with the diced apples.
Make the batter
- Beat butter and granulated sugar until fluffy, then add eggs and vanilla and beat until smooth.
- Whisk flour, baking powder, baking soda, and salt, then alternate adding the dry mix and buttermilk to the batter.
Assemble the loaf with a swirl
- Pour half the batter into the prepared pan.
- Layer in the spiced apple mixture and sprinkle the remaining spiced sugar over the apples.
- Top with remaining batter and swirl lightly with a knife for visible cinnamon-apple ribbons.
Bake and glaze
- Bake for 55-60 minutes at 350F, until a toothpick comes out clean (no wet batter).
- Mix glaze ingredients and drizzle over the loaf while warm so it sets into a thick sheen.
Notes
Pro tip: keep the loaf pan greased and avoid over-swizzling so the apple layers stay distinct in the crumb. Store covered in the refrigerator up to 4 days; rewarm slices briefly in the microwave for a fresh-tasting crumb. Freezing is yes—freeze individual slices up to 2 months and thaw overnight in the fridge. For a dairy-reduced option, use lactose-free buttermilk and substitute lactose-free milk in the glaze.
