Irish Apple Cake with Vanilla Custard is perfect in so many ways. First and foremost, it's delicious, but it is also a snap to prepare. Go with your favorite baking apple, but we always use Granny Smith. You could skip making the custard, but we don't recommend that. It puts the cake over the top in yumminess!

Make the Crumble Topping
In a medium-sized bowl, mix together the flour, oats, sugar, and salt. Use a knife to cut the butter into cubes and then rub it into the dry ingredients. Place in the refrigerator while you make the cake batter.
¾ cup all-purpose flour, ¼ cup rolled oats, ½ cup sugar, ¼ tsp salt, 6 tbsp unsalted butter
Make the Apple Cake
Use a stand mixer (or a hand mixer and a large bowl) to mix the softened butter with the sugar (this is creaming the two together) until light and fluffy, about 4 to 5 minutes.
8 tbsp unsalted butter, ½ cup sugar
Mix in the vanilla, and then beat in the eggs, one at a time.
2 tsp vanilla extract, 2 eggs
In a separate bowl, whisk together the flour, baking powder, cinnamon, and salt.
With the mixer running, slowly add the flour mixture to the wet mixture. Mix in the milk.
3 tbsp whole milk
Once the batter has come together (it will be thick), transfer it into the prepared pan. Next, layer the apples over the top of the batter and then sprinkle on the crumble mixture.

Bake for 55 minutes, or until the top is lightly browned and an inserted toothpick comes out clean.
Make the Vanilla Custard and Serve
Add the milk to a medium saucepan and bring to just a simmer (don't boil).
1½ cups whole milk
In a separate bowl, whisk together the eggs with the sugar.
6 egg yolks, 6 tbsp sugar
Whisking constantly, pour about half of the warmed milk into the eggs/sugar mixture.
Transfer back to the saucepan and cook over medium heat, stirring with a wooden spoon constantly, until just thickened (don't overcook!). Stir in the vanilla extract. If the custard is a little lumpy, then strain through a fine-mesh sieve.
2 tsp vanilla extract
Slice the cake and serve with the custard drizzled over the top.
