Step 1

Preheat your oven to 400° and line two large baking sheets with parchment paper or a silicone baking mat.

Step 2

Set out all of your ingredients before beginning and beat four of the eggs into a bowl until they are smooth.

Step 3

Place the water, milk, salt, sugar and butter in a saucepan. Bring to a boil, stirring occasionally with a wooden spoon to ensure the butter is melted before the water boils.

Step 4

As soon as the water boils and the butter is melted, immediately remove the saucepan from the heat and add the flour all at once, mixing quickly. Return the saucepan to the stove and stir vigorously for 15-20 seconds until the mixture forms a ball around the spoon and is beginning to leave a film on the bottom of the pan. Remove from the heat.

Step 5

Allow the dough to cool for 5-10 minutes so that it won’t instantly cook the eggs. Add about 1/4 of the beaten eggs to the pan and beat them in with the wooden spoon. The mixture will seem lumpy and strange at first, but as you continue to beat it will become cohesive and smooth.

Step 6

Repeat this process three more times with the rest of the beaten egg. At this point, you will want to test the dough. Hold up a scoop on your spoon and turn it sideways. If the choux dough stays in a firm ball or falls off of your spoon in a ball it needs more egg. You want it to fall off in thick but smooth ribbons. To achieve this consistency, beat the 5th egg until smooth, then beat in tiny bits of the egg until the dough is ready.

Step 7

While still warm, transfer the choux dough into a pastry bag fitted with a piping coupler. In one continuous squeeze, make balls of dough that are about 1.5” on the tray, leaving at least an inch between them. Place the tray in the oven and bake for 25 minutes, then remove them from the oven and pierce the side of each with a skewer or a sharp-tipped knife. Return the puffs to the oven and bake for another 5-10 minutes, or until the tops are a deep golden brown.

Step 8

Repeat the baking process with any remaining dough.

Step 9

In a medium mixing bowl, beat together the egg yolks and 1/4 cup of the milk. Add in the flour, cornstarch, and salt and beat until smooth with no lumps remaining. Set aside.

Step 10

In a medium saucepan, warm the 2 cups of milk and maple syrup over medium heat until it is steaming and small bubbles are forming around the edge. Pour a small amounts (a few tablespoons at a time) into the egg mixture, and whisk it in until smooth. Do this with about half of the milk to bring the eggs up to a similar temperature, then whisk it all back into the pot. Lower the heat to medium low and cook the mixture while whisking briskly and constantly. Do not leave it for even a second, as the maple syrup can scorch easily and the eggs will curdle.

Step 11

Continue cooking and stirring until the mixture is thick, about the consistency of yogurt. Immediately remove it from the heat, then whisk in the vanilla extract and butter until it is completely melted. Pour the mixture into a clean bowl and cover it with plastic wrap so that it is touching the cream. Set it in the refrigerator until it is completely chilled.

Step 12

To fill the puffs: Fit a piping bag with a round piping tip and a coupler (something like Wilton’s round tip and fill the bag with the pastry cream. If the cream has set thicker than you would like, whisk in a tablespoon of milk at a time until it has reached the desired consistency. Spoon the maple pastry cream into the bag.

Step 13

Find the slits in each of the puffs, and insert the piping tip into it. Squeeze the pastry cream into each puff until it is filled. Sprinkle the tops with powdered sugar and serve. Store in the refrigerator.
