Irish apple cake is the kind of cake that’s meant to be served warm, straight from the pan, with a jug of custard on the side. It’s less fussy than a pie and more apple than a coffee cake — the thick batter is barely enough to hold all the fruit together.
A scattering of demerara sugar and cinnamon over the top bakes into a crackly, crunchy crust. Tart apples like Granny Smith hold their shape and balance the sweetness.

Tips for the best irish apple cake
- Cut the apples small so they cook through evenly.
- Add a handful of blackberries with the apples in late summer.
- The cake keeps, covered, at room temperature for 2 days.

Irish Apple Cake
Rustic, buttery apple cake with a crunchy cinnamon-sugar top, best served warm with custard.
Ingredients
Method
- Heat the oven to 350°F. Butter a 9-inch springform pan and line the base with parchment.
- Whisk the flour, baking powder, cinnamon and salt in a bowl.
- Beat the butter and sugar with a hand mixer until pale and fluffy, about 3 minutes. Beat in the eggs one at a time, then the vanilla.
- Add the flour mixture in two additions, alternating with the milk, mixing just until smooth. Fold in the apples — the batter will be thick.
- Spread into the pan and sprinkle with the demerara sugar and cinnamon.
- Bake for 45 to 55 minutes, until golden and a skewer comes out clean. Cool for 15 minutes before releasing the pan. Serve warm with custard or whipped cream.
Notes
Keeps covered at room temperature for 2 days. Rewarm slices in a low oven before serving.
