Ever tried a dessert that feels like a warm hug? Irish Apple Cake is exactly that. This old-fashioned favorite, sometimes called “Kerry Apple Cake,” has been a part of Irish kitchens for ages. It’s a buttery, spiced cake filled with juicy, tart apple chunks and traditionally served with a creamy custard sauce. Simple, yet full of charm.
What makes this cake special? The apples. Ireland’s mild, rainy weather produces some incredible apples, and they shine in this dish. A touch of cinnamon and cloves adds that extra coziness we all crave—especially in cooler months.
I’ve taken this classic and added a modern twist: a streusel topping. It brings a little extra crunch and flavor while keeping all the comforting traditional vibes. Whether you’re celebrating St. Patrick’s Day or just want a dessert that feels like home, this Irish Apple Cake won’t disappoint.
What to Expect
This recipe is simple but impressive. Perfect for family dinners, holidays, or whenever you’re craving something sweet and wholesome. The best part? It’s not too fussy. You’ll need about 20 minutes to prep, plus 45–50 minutes of baking time. That’s just over an hour for a dessert that serves eight—generously.
Got a big crowd? No problem. Double the recipe and bake it in a 9×13-inch pan. Just give it a little extra time in the oven—about 10–15 minutes should do the trick.
Beginners, don’t be scared off! While this recipe has a few components (cake, streusel, and custard), the steps are straightforward. Take your time, follow along, and you’ll pull it off beautifully.

Here’s the lowdown on the ingredients. Most of these are pantry staples, so you might already have them!

- Granulated sugar
- Vanilla extract
- Eggs (room temp)
- All-purpose flour
- Baking powder

Want a grown-up twist? Add a splash of Bailey’s or whiskey to the custard. It’s like an Irish coffee but in dessert form.
Let’s Bake!
Step 1: Make the Cake Batter
- Preheat your oven to 350°F (180°C) and grease an 8-inch round pan. Line it with parchment paper for easy release.
- In a mixing bowl, cream the butter and sugar together until fluffy (about 2 minutes). Use a hand or stand mixer—whichever you prefer.
- Add the vanilla and eggs, one at a time, mixing well after each addition.
- In another bowl, mix the dry ingredients: flour, baking powder, cinnamon, and salt.
- Add the dry mix to the wet ingredients, alternating with the milk. Don’t overmix—it could make the cake dense.
- Fold in the apple chunks. The batter will be thick and chunky. That’s exactly how you want it! Pour it into your prepared pan.
Step 2: Prepare the Streusel
- Combine the flour, oats, sugar, and salt in a bowl.
- Add the cold butter (cut into small cubes). Use your fingers to rub it into the dry mix until it looks like coarse crumbs.
- Sprinkle it over the cake batter in an even layer. Gently press it down—just enough to keep it in place.
Step 3: Time to Bake
- Pop the cake in the oven for 45–50 minutes. Look for a golden-brown top and a toothpick that comes out clean.
- Let it cool in the pan for 15 minutes, then transfer to a wire rack. Or serve warm straight from the pan. No judgment here.
Step 4: Make the Custard Sauce
- Heat the milk with a pinch of salt in a saucepan over medium heat. Don’t let it boil!
- In a separate bowl, whisk the egg yolks and sugar until pale and thick.
- Slowly pour some of the warm milk into the egg mixture, whisking constantly (this prevents scrambling).
- Pour everything back into the saucepan and cook until it thickens slightly (it should coat the back of a spoon). Add vanilla, then take it off the heat.
Tips & Variations
- Gluten-free? Use GF all-purpose flour.
- Dairy-free? Switch to plant-based butter and almond milk.
- Vegan? Replace eggs with a flaxseed mix (1 tablespoon flaxseed + 3 tablespoons water per egg).
- Want a twist? Swap apples for pears in the fall or peaches in the summer.
If you’re short on time, skip the custard and serve this cake as-is with tea or coffee. It’s still divine.
Serving & Storing
Serve warm slices with a generous drizzle of custard sauce. For extra indulgence, try a dollop of whipped cream or a scoop of vanilla ice cream. Trust me, it’s worth it.
Leftovers? Store the cake at room temperature in an airtight container for up to two days. The custard keeps in the fridge for two days too—just reheat it gently before serving.
This cake isn’t just a dessert; it’s a little piece of Ireland on your plate. So grab your apron, bake a slice of history, and enjoy every bite!

For the Custard Sauce:

Instructions
1. Get the Cake Batter Ready
- Preheat your oven to 350°F (180°C). Grease and line an 8-inch round pan (parchment paper is your friend here).
- In a big bowl, beat the butter and sugar until it’s light and fluffy. About 2 minutes will do.
- Add the vanilla and eggs one at a time. Then mix in the milk.
- In another bowl, whisk together the flour, baking powder, cinnamon, and salt. Slowly fold the dry mix into the wet stuff until just combined.
- Stir in your apple chunks. The batter will be thick and apple-packed—totally normal!
2. Make that Streusel
- Mix the flour, oats (if using), sugar, and salt in a bowl.
- Toss in the cold butter cubes. Use your fingers to rub the butter into the dry mix until it looks crumbly—like small pebbles. Keep it in the fridge until you’re ready.
3. Assemble & Bake
- Pour the batter into your pan and spread it evenly.
- Sprinkle the streusel on top, pressing it down just a little so it stays put.
- Bake for 45–50 minutes, or until a toothpick in the center comes out clean.
- Let it cool for 15 minutes (if you can wait that long!).
4. Whip Up the Custard Sauce
- Heat the milk with a pinch of salt in a saucepan over medium heat. Don’t let it boil! Just warm it up.
- In a small bowl, whisk the egg yolks and sugar until they’re pale and slightly thickened.
- Slowly drizzle some of the warm milk into the egg mixture while whisking non-stop. Then, pour it all back into the saucepan.
- Cook over medium heat, stirring constantly, until the custard thickens—about 3–4 minutes. Once it’s ready, stir in the vanilla and set it aside.
Notes
How to Serve:
Serve warm slices of cake with a generous drizzle of custard sauce. Want to go all out? Add whipped cream or vanilla ice cream.
Pro Tips:
Go for Granny Smith apples if you love that tangy apple flavor. Prefer it sweeter? Use Honeycrisp or Golden Delicious.
For a perfect streusel, keep the butter cold. Rub it in quickly with your fingers to get a crumbly texture, or use a pastry cutter.
Storage & Reheating:
Store the cake in an airtight container at room temperature for up to 2 days—or in the fridge for up to a week.
Keep custard sauce in the fridge (in a sealed container) for up to 2 days. Warm it up on low heat before serving.
To reheat slices of cake, pop them in the microwave for 15–20 seconds.
