This is the kind of cake you could enjoy just about any time of year. It’s moist, hearty, and just bursting with tart, juicy apples. The more apples, the better. It packs in FOUR Granny Smiths, and the almost bread-y texture of the cake is a perfect foil. It really stands up to all that fruit.

There’s just a hint of warm spice in this recipe. Just enough to bring out the best in the fruit. This cake is really meant to be all about the apples, and boy, is it! They really shine in this authentic Irish dessert. Before it goes into the oven, the top of the cake gets a generous sprinkling of granulated sugar, for crunch and a beautiful sparkling crust. It’s fantastic!

Serve yourself a slice over a pool of creamy whiskey hard sauce. The caramel notes in the whiskey complement the apples in the most delicious way!

This cake works for any occasion. Serve it at brunch with coffee, bring it to a potluck, or offer it after dinner with a scoop of vanilla ice cream and watch it disappear.

With simple ingredients and classic flavors, this cake delivers great results. Let’s get started.

For the Irish Apple Cake

  • Cake flour: This gives the cake a soft, tender crumb. All-purpose flour works too, but the texture will be a bit more rustic.
  • Granulated sugar: Sweetens without weighing the cake down.
  • Baking powder: Make sure it’s fresh. If it has been in the cupboard since last year, it’s time for a fresh one.
  • Cinnamon: Adds warmth and that classic apple-cake flavor.
  • Kosher salt: Balances sweetness and helps to bring out the spice.
  • Cloves: A tiny amount goes a long way!
  • Nutmeg: Freshly grated tastes extra fragrant, but ground will work if that’s what you have.
  • Unsalted butter (softened): Adds richness and helps create a tender crumb.
  • Eggs: Use fresh eggs if you have access to them.
  • Buttermilk: Adds tenderness and a slight tang. See below for a substitution if you don’t have buttermilk.
  • Granny Smith apples: Tart, firm apples that hold their shape and taste amazing. Honeycrisp or Braeburn are great alternatives.
  • Sugar for garnish: Gives a lightly crackly, sweet top.

For the Whiskey Hard Sauce

  • Unsalted butter (softened): The base of the sauce, making it creamy and rich.
  • Powdered sugar: Sweetens while keeping the sauce smooth.
  • Irish whiskey: Adds warmth and a little bite. Use your favorite.
  • Vanilla extract: Rounds out the flavor.
  • Pinch of salt: Keeps the sweetness in check.
  • Heavy cream or milk (optional): Helps loosen the sauce if you want it softer and more drizzly.

How To Make Irish Apple Cake

Step 1: Prep your pan and oven

Preheat the oven to 350°F. Grease a 9-inch round cake pan and line the bottom with parchment paper for easy release.

Step 2: Mix the dry ingredients

In a medium bowl, whisk together the flour, sugar, baking powder, cinnamon, salt, cloves, and nutmeg until well combined.

Step 3: Cut in the butter

Add the softened butter and work it into the dry ingredients until the mixture looks like coarse crumbs.
You can use a pastry blender, two forks, or your fingertips for this step. A stand mixer on low also works, but be careful not to overmix.

Step 4: Add the eggs and buttermilk

Whisk the eggs with the buttermilk, then stir them into the batter until just combined. The batter will be thick.

Step 5: Fold in the apples

Gently fold in the chopped apples until evenly distributed.

Step 6: Bake

Spread the batter into the prepared pan and smooth the top. Sprinkle with a little sugar for garnish.

Bake for about 50 minutes, or until a toothpick inserted in the center comes out clean (or with a few moist crumbs).

Let the cake cool in the pan for 10 to 15 minutes, then turn it out onto a rack to cool.

Step 7: Make Sauce

  1. Beat until creamy – Beat softened butter until smooth and creamy.
  2. Sweeten and flavor – Gradually mix in powdered sugar, then add whiskey, vanilla, and a pinch of salt. Beat until fluffy.
  3. Adjust texture – If you prefer a thinner sauce, add a splash of cream or milk, a little at a time, until it reaches the consistency you like.

Step 8: Enjoy

Spoon over warm cake so it softens and melts into the crumb.

Helpful Tips and Tricks

  • Chop apples into small, even pieces so they bake up tender and distribute nicely.
  • Don’t overmix once the wet ingredients go in. Stir just until combined for a tender crumb.
  • Use parchment paper. This cake is moist, and parchment makes unmolding stress-free.
  • Serve the cake slightly warm for extra comfort, especially with the hard sauce.
