Step-by-Step Instructions

Preheat and Prep the Pan:
Begin by preheating your oven to three hundred seventy five degrees. Thoroughly grease your eight or nine inch cake pan and line the bottom with parchment paper to prevent sticking
Prepare the Apples:
Wash peel and dice your Granny Smith apples into half inch cubes. Set them aside in a bowl so they stay fresh while preparing the batter
Mix Dry Ingredients:
In a large mixing bowl sift together cake flour baking powder salt cinnamon nutmeg and cloves. Sifting ensures the spices and leaveners are evenly distributed and the cake will be light throughout
Cut in the Butter:
Working quickly use your fingers a pastry cutter or two knives to work the cold or room temperature butter into the flour mixture. The texture should look like coarse breadcrumbs. This creates a tender crumb that holds the apple chunks beautifully
Combine Wet Ingredients:
In a separate bowl whisk the eggs and whole milk together until well blended. This helps distribute the eggs for an even rich batter
Bring Together the Batter:
Pour the egg and milk mixture over the flour and apple mix. Use a large spatula or wooden spoon to fold the ingredients just until combined. The batter will be very thick and lumpy which is exactly right for supporting the apples
Fill and Top the Pan:
Transfer the thick dough into your prepared baking pan. Press it gently into the edges and smooth the top. Sprinkle the extra sugar evenly over the surface for a crisp golden finish
Bake the Cake:
Place the pan in the center of the oven and bake for forty five to fifty minutes. Test for doneness by inserting a toothpick or bamboo skewer into the center. It should come out clean or with a few moist crumbs. The aroma filling your kitchen is heavenly
Cool and Unmold:
Allow the cake to cool in the pan for ten minutes before gently turning it out onto a wire rack. Peeling off the parchment now guarantees easy slicing later
Serve with Custard:
Slice and serve your apple cake warm or at room temperature with a generous pour of homemade vanilla custard sauce for true Irish comfort

Every time I make the custard I am reminded of my grandmother’s gentle hands over the stovetop coaxing it to perfect silkiness. The custard sauce is my personal favorite part the way it wraps each bite in creamy comfort never fails to transport me back to family holidays around the table.

Storage Tips

Keep leftover cake wrapped tightly at room temperature for up to two days. For longer storage refrigerate and warm slices briefly before eating to bring back their tender crumb. You can also freeze individual slices well wrapped then thaw on the counter and serve as usual. Store extra custard in a lidded container in the refrigerator for up to three days stirring before using for best texture.

Ingredient Substitutions

If you do not have cake flour use all-purpose and subtract two tablespoons per cup replacing with cornstarch for tenderness. For a dairy-free option try a good plant milk in both cake and custard though flavor will differ slightly. Feel free to mix in a combo of crisp apples like Honeycrisp or Braeburn but always keep some tart varieties. Spices can be adjusted to taste.

Serving Suggestions

This rustic cake is wonderful for afternoon tea breakfast or dessert. I love offering it with warm custard at the table so everyone can pour their own. Whipped cream or a scoop of vanilla ice cream makes it festive for birthdays or St Patricks Day gatherings. If you are feeling traditional try it with clotted cream for extra richness.

A Bit of History

Irish apple cake is known as Kerry apple cake in some regions and has roots as a farmhouse staple using windfall apples and everyday ingredients. Its simple preparation and warming spices made it a staple for cooler months and family celebrations. Baking this cake connects you with generations of Irish bakers who prized resourcefulness and heartwarming flavor.

Ingredients

→ Cake

01 360 g cake flour
02 2 teaspoons baking powder
03 0.5 g salt
04 0.5 teaspoon ground cinnamon
05 0.5 teaspoon ground nutmeg
06 0.5 teaspoon ground cloves
07 170 g salted butter, cold or at room temperature
08 200 g granulated sugar
09 2 large eggs
10 3 large Granny Smith apples, peeled and diced
11 240 ml whole milk
12 25 g granulated sugar, for topping

→ Custard Sauce

13 6 large egg yolks
14 50 g granulated sugar
15 360 ml whole milk
16 1 tablespoon vanilla extract

Instructions

Step 01

Preheat the oven to 190°C. Grease the base and sides of an 20–23 cm round baking pan and line the base with parchment paper.

Step 02

Wash, peel, and dice the Granny Smith apples. Set aside.

Step 03

In a large mixing bowl, sift together cake flour, baking powder, salt, cinnamon, nutmeg, and cloves.

Step 04

Cut the salted butter into the flour mixture until the texture resembles coarse crumbs.

Step 05

Mix in the granulated sugar, then gently fold in the diced apples, ensuring they are evenly coated with the flour mixture.

Step 06

In a separate bowl, whisk together the eggs and whole milk.

Step 07

Add the egg and milk mixture to the flour-apple mixture. Stir gently with a large spatula or wooden spoon until a thick batter forms.

Step 08

Transfer the batter to the prepared pan. Smooth the surface and ensure the batter fills the corners. Sprinkle the reserved sugar evenly on top. Bake for 45–50 minutes, or until a skewer inserted into the center comes out clean.

Step 09

Allow the cake to cool in the pan for 10 minutes. Transfer to a wire rack to cool completely.

Step 10

Whisk together egg yolks and granulated sugar in a mixing bowl. In a saucepan over medium-low heat, warm the milk until steaming but not simmering. Gradually whisk some hot milk into the egg mixture to temper it, then pour the egg mixture back into the saucepan. Cook gently over low heat, whisking constantly, until the custard thickens enough to coat the back of a spoon, about 5–10 minutes. Remove from heat and let cool for 10 minutes, stirring occasionally. Whisk in vanilla extract.

Step 11

Slice the cooled cake and serve warm or cold, accompanied by warm or chilled custard sauce.

Notes

  1. Ensure the milk for the custard does not boil to prevent scrambling the eggs.
  2. The cake can be served cold or gently reheated; both ways pair well with custard.
