Method
Prep and mix the cake batter
- Preheat the oven to 350°F and grease a 9x13 pan for easy release.
- Beat the softened butter and sugar until fluffy, then add the eggs and vanilla extract and mix until smooth.
- Alternate adding the dry flour mixture (flour, baking powder, salt, and cinnamon) and the whole milk, mixing just until the batter is combined.
- Fold in the diced apple so the pieces are evenly distributed throughout the batter.
Add cinnamon swirl
- Pour half the batter into the pan and sprinkle the cinnamon swirl mixture over it.
- Pour the remaining batter on top, then swirl with a knife to create streaks of cinnamon throughout.
Bake and glaze
- Bake at 350°F for 40–45 minutes, until a toothpick comes out clean and the top looks golden.
- Poke holes all over the warm cake and pour the vanilla glaze over the top immediately so it sinks in.
Notes
Pro tip: Swirl with a light hand—visible cinnamon ribbons help mimic an apple fritter texture in every slice. Store covered in the fridge up to 4 days; rewarm individual portions in the microwave 15–20 seconds. Freezing is yes—freeze slices (glaze side up) up to 2 months and thaw overnight in the fridge. For a lighter option, swap half the butter for an equal amount of unsweetened applesauce.
