Apple Crumble With Homemade Vanilla Custard

Jump to Recipe

If something makes me excited for Autumn then it is this apple crumble with homemade vanilla custard. It is out of this world good!

And here is why! This apple crumble is made with grated and chopped apples. Beacause of the grated apples this filling is creamier, juicier but not to wet. And I like to use granny smith apples for this apple crumble with custard. Their sourness goes beautifully with sweet rest of the crumble.

I used rye for this apple crumble with oats or apple crumble with oatmeal, but of course use oats if you prefer.

Then for vanilla custard for this apple crumble with homemade vanilla custard, I made my go to custard. But if you want the custard looser/runnier then add less cornstarch. This vanilla custard recipe is very easy to make. All you have to think about is to start adding the milk to the egg mixture in slow stream in the beginning. Then as soon as custard starts to thicken in the pot, continue cooking for a couple more seconds and remove from heat. This might take you some practice, but it really is very simple once you get a hang of it.
