Step-by-Step Instructions for the Perfect Irish Apple Cake

Preheat and Prep: Begin by preheating your oven to 350°F. Grease a 9-inch springform pan and set aside.
Make the Custard Sauce:
- Warm 1½ cups of whole milk in a saucepan until it simmers.
- In a separate bowl, whisk together 6 egg yolks and 6 tablespoons of sugar.
- Temper the eggs by slowly adding a small amount of hot milk while whisking continuously.
- Return the mixture to the saucepan and cook on medium heat, stirring constantly until it thickens to coat the back of a spoon.
- Remove from heat, stir in 1½ teaspoons of vanilla, and strain through a sieve.
- Chill in the refrigerator with plastic wrap touching the surface to prevent skin formation.
Prepare the Streusel Topping:
- Combine flour, sugar, and oats with cold butter.
- Work until the mixture resembles coarse crumbs. Chill until ready to use.
Make the Cake Batter:
- Cream ½ cup of softened butter and ½ cup of sugar until light.
- Add 2 eggs, one at a time, beating well.
- In a separate bowl, whisk 1¼ cups flour, 1 teaspoon baking powder, 1 teaspoon cinnamon, and ⅛ teaspoon salt.
- Gradually mix the dry ingredients into the wet mixture, alternating with 3 tablespoons of milk or cream.
Assemble the Cake:
- Spread the batter into the prepared pan.
- Layer thinly sliced apples (about 3 Granny Smiths) evenly over the top.
- Sprinkle the chilled streusel over the apples.
Bake:
- Bake for 50–60 minutes, or until the top is golden and a toothpick inserted in the center comes out clean.
- Let it cool slightly before removing from the pan.
- Dust with powdered sugar before serving.

Expert Tips & Tricks for Success

Storage: Store the cake covered at room temperature for up to 2 days, or refrigerate for longer shelf life.
Reheating: Warm slices in the microwave or oven before serving to enhance the cake’s aroma and flavor.
