Irish Apple Cake with Custard Sauce

While most countries have their own spin on a delicious apple confection, Ireland is most known for its Kerry Apple Cake (also known as Irish Apple Cake). It might be a little closer to an apple bread, but it’s got the perfect touch of sweetness running through the batter, plus a sprinkling of sugar on top before it bakes in the oven gives it a gorgeous (and delicious) crackled top that ties everything together. Not only that, but there’s also a silky smooth custard sauce that gets drizzled over the top…perfection, we tell you.

Let’s dive deeper into this cake, shall we? First off, this cake is jam-packed and stuffed to the brim with apples. This is truly a behemoth of a batter; don’t be surprised when it doesn’t come together the way a typical cake batter would. Instead of creaming together your butter and sugar, this cake comes together a bit more like a shortbread, with butter getting cut into the dry ingredients, then only after the apples get folded into the butter and flour mixture do the wet ingredients get poured in. Do your best to not overmix the batter – we still want the cake to be light and fluffy – then pour it into a springform pan and top it off with a generous sprinkle of sugar.

Once the whole thing goes into the oven you can focus on making the custard. Yes, you have to temper six egg yolks, but don’t be intimidated – it’s actually easy! The important thing here is to keep your saucepan on medium (or even medium-low!) heat. Warm your milk until it’s just scalded and there are bubbles along the edge of the pan, then pour that mixture into your egg yolks while you whisk continuously. This slowly raises the temperature of the eggs so they don’t scramble when you return them to the stove. They’ll thicken on the heat and give the custard sauce all its rich creaminess.

Once this gets drizzled over the cake, the jig is up. Anyone who had been able to abstain from devouring a slice will surely cave (and be so glad they did.) This is a traditional dessert that’s time-tested and absolutely deserving of its spot in our recipe tin.
