how to make Irish Apple Cake with Custard and Oat Streusel

Ingredients:

  • 1/2 cup unsalted butter, at room temperature
  • 1/2 cup granulated sugar
  • 2 large eggs
  • 3 Tbsp whole milk or cream
  • 1 1/4 cups all-purpose flour
  • 1 tsp baking powder
  • 1 tsp cinnamon
  • 1/8 tsp salt
  • About 3 Granny Smith apples, peeled and thinly sliced (a little over a pound after slicing)
  • 3/4 cup all-purpose flour
  • 1/4 cup old-fashioned rolled oats
  • 6 Tbsp unsalted cold butter, cut into small pieces
  • 1/2 cup granulated sugar
  • 6 large egg yolks
  • 6 Tbsp granulated sugar
  • 1 1/2 cups whole milk (or half and half or cream)
  • 1 1/2 tsp vanilla extract
  • Confectioner’s sugar, for dusting

Directions:

  1. Preheat the oven to 350°F and grease a 9-inch springform pan to prevent sticking and ensure easy removal of the cake.
  2. Heat the milk over medium heat until just simmering.
  3. In a separate bowl, whisk together the egg yolks and sugar until combined. Gradually drizzle hot milk into the egg mixture while whisking constantly to temper the eggs.
  4. Return the mixture to the pan with the remaining hot milk and cook over medium heat, stirring continuously with a silicone spatula until it coats the back of a spoon.
  5. Remove from heat and stir in vanilla extract. Strain through a sieve into a heatproof container, cover with plastic wrap touching the surface to prevent skin, and refrigerate until completely chilled.
  6. Combine flour, oats, and sugar in a bowl. Cut cold butter into the mixture using fingers or a pastry cutter until coarse crumbs form. Refrigerate this topping until ready to use.
  7. In a mixing bowl, beat the softened butter and sugar until the mixture is light and fluffy.
  8. Beat in the eggs one at a time to the creamed mixture. In a separate bowl, whisk flour, baking powder, cinnamon, and salt. Fold these dry ingredients into the wet mixture along with the milk or cream until just combined.
  9. Spoon the batter into the prepared pan and smooth evenly. Arrange the sliced apples evenly over the batter.
  10. Sprinkle the chilled streusel topping evenly over the apples.
  11. Bake in the preheated oven for 50 minutes to 1 hour until the top is lightly browned and a toothpick inserted comes out clean or with a few moist crumbs.
  12. Let the cake cool slightly in the pan before removing the sides of the springform. Dust the top with confectioner’s sugar. Serve with the chilled vanilla custard sauce alongside.
