Homemade Vanilla Custard Sauce for Desserts
This homemade vanilla custard sauce is silky, rich, and subtly flavored with real vanilla. Thickened with a touch of cornstarch for extra creaminess, it's the perfect companion to warm blueberry pie, fruit crumbles, or soft cakes. A classic, comforting sauce that elevates any dessert.
Ingredients
- 2 dl 200 ml whole milk
- 3 dl 300 ml heavy cream
- 3 egg yolks
- 3 tbsp fine sugar
- 1 vanilla pod
- 2 tsp cornstarch
- 1 tbsp cold water
Instructions
- In a small bowl, mix the cornstarch with 1 tablespoon of cold water to form a smooth slurry. Set aside.
- In a heavy-bottomed saucepan, combine the egg yolks, milk, cream, and sugar.
- Split the vanilla pod lengthwise and scrape out the seeds. Add both the seeds and the pod to the pan.
- Warm the mixture over medium-low heat, stirring constantly.
- Once the custard is warm (not hot), add the cornstarch slurry, continuing to stir.
- Cook the custard slowly until it thickens slightly and coats the back of a spoon — prevent from boiling. This should take about 8–10 minutes.
- Remove from the heat, pour into a jug or bowl, and press plastic wrap directly on the surface to prevent a skin from forming.
- Let cool, then chill fully in the fridge. Remove the vanilla pod before serving.
Notes
- Serve chilled alongside warm fruit pies, especially blueberry pie, apple crumble, or as a rich drizzle over sponge cakes and summer berries.
- No vanilla pod? You can substitute with 1–2 teaspoons of vanilla bean paste or pure vanilla extract. Add it at the end of cooking, just before cooling, to preserve the flavor.
- Prevent curdling: Keep the heat low and stir constantly. The sauce should never boil. A gentle heat ensures a smooth, velvety texture.
- Storage: Store in an airtight container in the refrigerator for up to 3 days. Place a piece of plastic wrap directly on the surface to prevent skin from forming.
- Serving idea: This vanilla sauce is perfect with warm blueberry pie, apple crumble, or rhubarb desserts. It can also be used as a base for chilled dessert cups with berries.
- Bonus tip: After removing the vanilla pod from the sauce, rinse and let it dry. Place the pod in a jar with some sugar and a lid. After a few days, you’ll have homemade vanilla sugar for baking or coffee!
