Irish Apple Cake Recipe

My Irish apple cake recipe is loaded with fresh Granny Smith apples, warm spices, and a buttery crumb topping that bakes in about 50 minutes. I bake it in a springform pan for easy slicing, and I drizzle my homemade custard sauce over each piece before serving to my friends and family. This is the dessert I look forward to making every St. Patrick’s Day.

On the weekends leading up to St. Patrick’s Day, I start planning my menu weeks in advance because it is one of my favorite holidays to cook for. Honestly, this apple cake always makes the list because it is simpler than a traditional apple pie but just as impressive on the table. I typically bake it on the same day I make a loaf of my easy Irish soda bread, so the whole house is in full celebration mode. Even though the custard sauce is optional, in my house, it is the finishing touch that makes my whole crew come running to the kitchen. It is that good!

This Irish apple cake starts with a buttery crumb batter loaded with fresh Granny Smith apple chunks and warm spices like ginger, nutmeg, cinnamon, and allspice. I pour the batter into a springform pan, sprinkle cinnamon sugar on top, and bake for about 45 to 50 minutes until a toothpick comes out clean. While the cake cools, I make a simple custard sauce by whisking egg yolks with hot milk until thick enough to coat a spoon. I drizzle it over each slice, warm or cold, and the combination of tender cake, tart apples, and creamy custard is something I look forward to every year. I hope you give this one a try, too!

Why you will love this recipe

• Easier than apple pie: I love that this cake gives me all the warm apple flavors I crave without the hassle of rolling out pie dough.
• No mixer needed: I make this entire cake by hand with just a whisk and my fingertips. No stand mixer or hand mixer required, which means less cleanup for me.
• Great for a crowd: I bake this in a springform pan and slice it right at the table. One cake feeds my whole family with leftovers for the next morning with coffee.
• Custard sauce takes it over the top: The optional sauce turns this simple cake into an elegant dessert. I serve it warm for holidays or cold for a refreshing finish on warmer days.

What you will need

For the cake:

• All-purpose flour: I use this as the base of the cake. Cake flour also works if you want an even more tender crumb.
• Baking powder: This is the leavening agent that helps the cake rise. Make sure not to substitute with baking soda.
• Spices: I use sea salt, ground ginger, nutmeg, cinnamon, and allspice to create a warm, aromatic blend.
• Unsalted butter: I use cold butter cut into small pieces.
• Granulated sugar: I use it in the batter, plus a little extra mixed with cinnamon for the topping. You can substitute half of the sugar with brown sugar for a richer flavor.
• Granny Smith apples: Peeled, cored, and diced into small chunks.
• Milk: Any milk works to bring the batter together.
• Eggs: Large eggs at room temperature.
• Vanilla extract: Pure vanilla rounds out the warm spice flavors.

Custard Sauce:

• Whole milk: I heat it just until it begins to boil. Whole milk gives the creamiest result.
• Egg yolks, whisked with sugar, create the rich base of the sauce.
• Granulated sugar: Sweetens the custard and balances the tartness of the cake.
• Vanilla extract: I stir this in at the end for a smooth finish. 

How to make

For the cake:

1. Prep and mix: I preheat my oven to 375 degrees F and butter and flour a 9-inch springform pan. In a large bowl, I whisk together the flour, baking powder, salt, ginger, nutmeg, cinnamon, and allspice. I add the cold diced butter and work it in with my fingertips until the mixture looks like fine crumbs, then stir in 1 cup of sugar.

2. Add the apples: I peel, core, and dice the apples into small chunks and toss them into the flour mixture until evenly coated. I make sure to separate the pieces so they do not stick together.

3. Combine wet and dry: In a separate bowl, I whisk together the milk, eggs, and vanilla. I pour this over the apple and flour mixture and toss just until combined. The batter will be lumpy and that is perfectly fine.

4. Bake: I transfer the batter into the prepared pan and spread it evenly. I mix the remaining 2 tablespoons of sugar with 1/2 teaspoon of cinnamon and sprinkle it on top. I bake for 45 to 50 minutes until a toothpick comes out clean.

5. Cool: I let the cake cool on a wire rack for 5 to 10 minutes before removing the springform ring. I let it cool completely before slicing.

For the custard sauce:

1. Heat the milk: I heat whole milk with a pinch of salt in a saucepan over medium heat until it comes to a light boil.

2. Whisk the yolks: In a separate bowl, I beat the egg yolks and sugar until pale and fluffy, about 1 to 2 minutes.

3. Temper and cook: I slowly pour 1/2 cup of hot milk into the yolk mixture while whisking. Then I pour everything back into the saucepan and cook over medium-low heat, whisking constantly for 3 to 4 minutes until it coats the back of a wooden spoon.

4. Finish: I pour the custard into a glass container, stir in the vanilla, and cover with plastic wrap pressed against the surface to prevent a skin from forming. I serve warm or cold over the cake.

Expert tip

Do not overmix the batter

I can’t stress this enough. The less I mix, the more tender the cake will be. Once I pour the wet ingredients over the apple and flour mixture, I use my hands or a spatula to toss everything just until combined. Overmixing develops the gluten in the flour, resulting in a tough cake. A few lumps in the batter are perfectly normal and will be gone during baking.

More tips to consider:

• I watch the custard sauce carefully and whisk constantly. If it overheats, the eggs will curdle. I remove it from the heat as soon as it coats the back of a spoon.
• I use cold butter and work it in quickly with my fingertips. Warm butter will not create the crumbly texture that makes this cake so tender.
• I cut the apples into small, uniform chunks, so they cook well. Larger pieces can stay crunchy while smaller ones get too soft.
• I use a springform pan for the easiest removal. The cake is dense and fragile when warm, so the removable ring prevents it from breaking.
• I keep the eggs at room temperature so they blend smoothly with the milk and vanilla. Cold eggs can make the batter lumpy.

Recipe variations and add-ins:

• Brown sugar swap: I sometimes replace half of the white sugar with 1/3 cup of brown sugar to deepen the caramel flavor. The molasses in the brown sugar pairs so well with the warm spices.
• Irish butter version: I use Irish butter when I can find it because the higher fat content makes the cake extra tender. It is worth the splurge for party occasions.
• Apple muffins: I pour the batter into a lined cupcake pan instead of a springform for individual servings. I start checking at 30 minutes instead of 45.
• Heavy cream custard: I substitute heavy cream for the milk in the custard sauce to make a thicker, more indulgent treat I love.
• Streusel topping: I replace the cinnamon sugar with a quick streusel made from about 1/3 cup each of flour, brown sugar, and cold butter. The crunchy topping adds amazing texture that my kids prefer.

Serving suggestions:

I honestly enjoy serving this cake warm with the custard sauce drizzled generously over each slice. A scoop of whipped cream on the side makes it even more indulgent. For St. Patrick’s Day, I serve it as dessert after my Guinness pot roast with a side of beer bread to complete the meal. My easy shepherd’s pie also pairs perfectly as the main course before this cake.

This Irish Apple cake also makes a stunning centerpiece on a dessert table. I dust the top with powdered sugar for an elegant finish when I am entertaining. After dinner, I love pairing a slice with a baileys affogato for an adults-only treat. For a full Irish dessert spread, I set it out alongside my Guinness chocolate brownies and let everyone pick their favorite.

How to store leftovers:

• Store: I keep leftover cake in an airtight container in the refrigerator for up to 3 days. I store the custard sauce separately in a covered jar so it stays fresh.
• Freeze: I wrap individual slices tightly in plastic wrap and place them in a freezer-safe bag for up to 3 months. I freeze the custard sauce in a separate container.
• Thaw: I move frozen slices to the refrigerator overnight to thaw slowly.
• Reheat: I warm individual slices in the microwave for about 20 to 30 seconds. I reheat the custard sauce separately and drizzle it over the custard right before serving.
