Gather Your Ingredients
Making cream puff filling is easier than you might think. First, gather your ingredients. You will need 1 cup heavy cream, 1 cup milk, 1/2 cup granulated sugar, 3 egg yolks, and 1/4 cup cornstarch. You may also want to add some vanilla extract or other flavorings to taste.
Whisk the Eggs and Sugar
Begin by whisking the egg yolks and sugar together in a medium-sized bowl until they are well combined. Set this bowl aside while you prepare the rest of the ingredients.
Combine Milk and Cream
In a medium saucepan, combine the milk and heavy cream. Heat the mixture over medium heat, stirring occasionally, until it begins to steam.
Add Cornstarch Mixture
While the milk and cream are heating up, whisk the cornstarch into the egg and sugar mixture until it is smooth. Once the milk and cream are steaming, slowly pour the egg mixture into the saucepan, whisking constantly to prevent any lumps.
Cook the Filling
Place the saucepan back on the stove over medium heat. Cook the mixture, whisking constantly, until it thickens and comes to a boil. Continue to cook and whisk for another minute or two, until the filling is very thick.
Flavor the Filling
Remove the saucepan from the heat and add any flavorings you desire. This could be vanilla extract, almond extract, or any other flavoring you like. Whisk the flavorings into the filling until they are well combined.
Cool the Filling
Pour the filling into a bowl and cover it with plastic wrap, pressing the wrap directly onto the surface of the filling to prevent a skin from forming. Chill the filling in the refrigerator until it is completely cool, at least 30 minutes.
Fill Your Cream Puffs
Once the filling is chilled, it is ready to be used. Use a piping bag or a spoon to fill your cream puffs with the filling. You can also use this filling to fill eclairs, donuts, or other pastries.
