Vanilla Custard Sauce
While the cake is in the oven prepare the custard sauce.

In a medium saucepan bring milk to a simmer over medium-low heat, do not boil.
In a separate bowl whisk together egg yolks and sugar until combined.

Whisk a small amount of the heated milk into egg mixture and mix until combined. Stir in the remaining milk and mix well.
Return to the saucepan and return heat to medium high.


Pro Tip
- By adding a small amount of the hot milk to the egg mixture, you are tempering the eggs. This brings the eggs to a similar temperature as the hot liquid, ensuring a smooth and velvety custard without any scrambled eggs or unwanted lumps. Patience is key! A slow and steady stream while whisking prevents curdling, leaving you with a perfect custard every time.
Continue stirring custard until thickened, 3 to 5 minutes or until the mixture sticks to the back of a spoon.

Remove from heat and enjoy with your homemade apple cake!


Tips & Tricks
- Make sure that the butter and eggs are at room temperature. This helps in achieving a smooth and even batter, which will give you a moist and tender cake.
- When slicing the apples for the cake, aim for thin slices. A mandolin can be very helpful slicing thin, uniform apple slices in a short amount of time.
- Mix the wet ingredients with the dry ingredients until just combined. Overmixing can result in a denser cake. It’s ok if there are a few lumps, they will disappear during baking.
- For the streusel topping, use cold butter and work it into the dry ingredients until you achieve a crumbly (pea size) texture.
- Temper the eggs for the custard sauce by gradually whisking in a small amount of the warm milk mixture. This prevents the eggs from curdling and ensures a smooth, creamy custard.
- Cook the custard over low heat and stir continuously. Patience is key to achieving a velvety texture. If it overheats or cooks too quickly, you may end up with a grainy consistency.
