Method
Bake the cake layers
- Preheat oven to 350F, then grease two 9-inch round pans with a light coating so the layers release cleanly (visual cue: pan surfaces look shiny, not dusty).
- Beat butter and brown sugar until smooth, then add eggs one at a time and beat in the vanilla (visual cue: mixture looks paler and thicker).
- Alternate adding dry ingredients and sour cream, mixing just until combined after each addition (visual cue: batter becomes uniform with no dry streaks).
- Fold in finely diced apples until evenly distributed (visual cue: specks of apple are suspended throughout the batter).
- Divide batter evenly between the two pans, then bake at 350F for 50-55 minutes (visual cue: tops spring back and a toothpick comes out clean).
Frost and assemble
- Cool cake layers completely before frosting (visual cue: layers are fully room-temperature with no warmth at the centers).
- Beat frosting ingredients until very fluffy, using a longer beat so it lightens in texture (visual cue: frosting holds soft peaks).
- Frost between the layers and then spread frosting over the top and sides (visual cue: smooth, even coverage with a lightly swirled top).
Notes
For best texture, dice the apples small and consistent so they bake through without pockets. Store covered in the refrigerator up to 4 days; freeze unfrosted layers up to 2 months (thaw overnight in the fridge, then frost). For a lighter option, use low-fat cream cheese and low-fat sour cream for a similar tang with slightly less richness.
