This Irish Apple Crumble Cake is a moist and tender, buttery cake that's packed with fresh apples and topped with a delicious crumble. And easy? Oh my, yes. Delicious? Absolutely!
Preheat the oven to 350°F. Grease and line a 9-inch springform or round cake pan. Set aside.
Streusel Topping
Using a hand mixer or pastry cutter, blend the crumble topping ingredients into coarse crumbles. This can also be done with your fingertips. Refrigerate until ready to use.
Apple Cake
Cream the butter and sugar together using an electric hand mixer or stand mixer, until pale, light, and fluffy. Mix in the eggs, one at a time, beating until fully incorporated.
Fold the flour, baking powder, salt, and cinnamon into the butter mixture. Then fold in the milk or cream until a smooth but thick cake batter forms. Fold in half the apples, then transfer the batter to the prepared cake pan. Use a spatula to evenly spread the batter to the edges of the pan.
Top the cake batter with the remaining apples in an even layer, and then sprinkle the crumble over the top.
Bake for 40-45 minutes or until a toothpick inserted in the center comes out clean. Let cool in the pan 10 minutes before transferring to a rack to cool.
