Tips & Tricks

→ Use cold butter for the crumble - Make sure the butter is cold and cut into small cubes before working it into the flour and sugar. Work it into the dry ingredients just until you have a mixture of smaller crumbs with a few larger pieces throughout.

→ Make the vanilla custard first - I recommend preparing the custard before starting on the apple crumble so it has plenty of time to cool and slightly thicken. Once cooked, transfer it to a separate container and refrigerate it while you prepare the rest of the recipe.

→ Don't rush when tempering the eggs - When adding the hot milk and cream mixture to the egg yolks, pour it in very gradually while whisking constantly. Adding too much hot liquid at once can cook the yolks and leave you with pieces of scrambled egg instead of a smooth custard. Slowly bringing the eggs up to temperature is one of the most important steps for achieving a silky texture.

→ Use a thermometer for the custard if you have one - A kitchen thermometer takes a lot of the guesswork out of making custard. Cook the mixture gently until it reaches around 82°C (180°F). Avoid boiling it, as excessive heat can cause the eggs to curdle. The finished custard should be slightly thickened while still having a pourable consistency.

→ Use an 18x25 cm ceramic baking dish - I baked this crumble in an 18x25 cm ceramic baking dish, which gives you a good balance between the apple layer and crumble topping. Using a significantly larger or smaller dish will change the thickness of the layers and may also affect the baking time.

→ Serve the apple crumble warm - This dessert is best served while the apple filling is still warm and the crumble topping is freshly baked. Spoon it into bowls, then generously pour the homemade vanilla custard over the top.

Frequently Asked Questions

1. How should I store Apple Crumble?
Once completely cooled, cover the baking dish tightly or transfer the leftovers to an airtight container and store them in the refrigerator for up to 3 days. Keep the homemade vanilla custard refrigerated separately in an airtight container.

2. How do I reheat apple crumble?
You can reheat individual portions in the microwave for a quick option, but reheating the crumble in the oven will help bring back some of the texture in the topping. Heat it at around 160-170°C until warmed through.

3. Can I make the apple crumble ahead of time?
Yes. You can prepare the different components in advance, but for the best texture, I recommend baking the crumble closer to serving. The vanilla custard is especially convenient to make ahead because it needs time to cool and thicken in the refrigerator.

4. Can I make the vanilla custard ahead of time?
Absolutely. You can prepare the custard a day in advance and keep it covered in the refrigerator.

5. Why is my vanilla custard lumpy?
Lumpy custard is usually caused by heating the egg mixture too quickly or cooking it at too high a temperature. Pour the hot milk mixture into the yolks gradually while whisking constantly, then cook the custard gently. Straining the finished custard will also help remove any small pieces of cooked egg.

6. Why isn't my vanilla custard thickening?
The custard may simply need a little more time over the heat. Since this is a pourable custard rather than a thick pastry cream, it will only thicken slightly while cooking and will become a little thicker as it cools. If you have a thermometer, aim for around 82°C (180°F).

7. Can I use vanilla extract instead of a vanilla pod?
Yes. A vanilla pod gives the custard a beautiful, rich vanilla flavor, but vanilla bean paste or vanilla extract can also be used. If using extract, add it toward the end of cooking for the best flavor.

8. Do I need to peel the apples?
This comes down to personal preference. You can peel the apples for a softer, more uniform filling or leave the skins on if you enjoy a little more texture.

Ingredients You Will Need For This Recipe

For the Vanilla Custard

Egg yolks: Give the custard its rich flavor, creamy texture.
Granulated sugar: Sweetens the custard.
Vanilla pod: Gives the custard a deep, natural vanilla flavor. Scrape out the seeds and add both the seeds and pod to the milk and cream while heating so you get as much vanilla flavor as possible. Remove the pod before finishing the custard.
Whole milk: Makes up the majority of the liquid in the custard and keeps it creamy while still maintaining a pourable consistency.
Heavy cream: Adds extra richness and gives the custard a smoother, silkier texture.

For the Apple Layer

Apples: The base of the filling.
Dark brown sugar: Sweetens the apples while adding a deeper caramel like flavor that pairs beautifully with the cinnamon and vanilla.
Butter: Adds richness to the apple filling and helps the apples cook down before baking. You can use either salted or unsalted butter here.
Ground cinnamon: Adds plenty of warm, cozy flavor to the apples.
Vanilla bean powder: Adds another layer of warm vanilla flavor to the apple filling. If you don't have vanilla bean powder, vanilla bean paste can also be used.
Water: Creates a little extra moisture while the apples cook, helping them soften without sticking to the pan.

For the Crumble

All-purpose flour: Forms the base of the crumble topping.
Granulated sugar: Sweetens the crumble while helping the topping become beautifully golden as it bakes.
Salt: Balances the sweetness and enhances the flavor of the crumble topping.
Vanilla bean powder: Adds a rich vanilla flavor directly to the crumble.
Unsalted butter: Creates the rich, buttery crumble texture. Make sure the butter is cold and cut into cubes before mixing it into the other ingredients. Keeping it cold helps create distinct crumbs and gives the topping a better texture once baked.

Step By Step Instructions With Photos

1. First, prepare the vanilla custard so it has time to cool.

2. Add the milk, heavy cream, scraped vanilla seeds and vanilla pod to a saucepan. Heat over medium heat until the mixture just comes to a simmer.

3. In a separate bowl, whisk together the egg yolks and granulated sugar until pale and creamy.

4. Gradually pour the hot milk mixture over the egg yolk mixture while whisking continuously to temper the eggs.

5. Once tempered, strain the mixture back into the saucepan.

6. Cook over medium-low heat, stirring continuously, until the custard thickens slightly and reaches 82°C. Do not let it boil.

7. Once ready, pour the vanilla custard into a separate container and place it in the fridge to cool.

8. Next, prepare the apple layer.

9. Melt the butter in a saucepan over medium heat.

10. Add the cubed/sliced apples, brown sugar, cinnamon, vanilla bean powder and water. Mix until the apples are evenly coated.

11. Cover and cook over medium heat for about 15 minutes, stirring occasionally, until the apples have softened slightly.

12. Transfer the apple mixture to a ceramic baking dish and spread it out evenly. I used an 18×25 cm ceramic baking dish. Set aside.

13. Preheat the oven to 180°C.

14. To prepare the crumble topping, add the flour, granulated sugar, salt and vanilla bean paste to a bowl and mix to combine.

15. Then, add the cold cubed butter.

16. Using your fingertips, work the butter into the dry ingredients until you have a buttery, crumbly mixture with some larger crumbs throughout.

17. Sprinkle the crumble topping evenly over the prepared apples.

18. Bake in the preheated oven for about 30 minutes, or until the crumble is golden brown and the apple filling is bubbling around the edges.

19. Once baked, let the apple crumble cool for about 10 minutes before serving.

20. Serve warm with the chilled vanilla custard and enjoy!
