This easy pastry cream recipe takes about 15 minutes and produces a rich, creamy vanilla custard using a simple, one-pot method
This recipe is designed to be just sweet enough, with a perfectly smooth and creamy texture that isn’t overpowered by a starchy taste. This cream will set pretty firmly. If you want it to have a smooth, silky consistency, whisk it before use. For a sweeter pastry cream, increase the sugar to 1/2 cup. For a thicker cream, add up to 1/3 cup of cornstarch, but this may add a starchy aftertaste. If you are making a tart with this pastry cream, for more stabile pastry cream with neat slices, set the warm pastry cream into the tart to set.
While making the custard, Keep both a rubber spatula and a whisk handy to ensure even cooking. Alternate between them to scrape the edges of the pot and to whisk for even consistency. Stay with the pot while cooking; the process takes no more than 10 minutes. Stir constantly at the beginning to prevent the egg yolks from sticking to the bottom of the pot and scrambling.
Pastry cream is best used within 1 to 2 days of being made. As the days go on, the cream might release some moisture. This is fine to consume, just stir it back into the cream before using.
