Preheat oven to 400°F.
In a small pot, bring your water, milk powder and butter to a simmer/slight boil.
150 g Water, 6 g Milk Powder, 67 g Butter
Add the flour and salt into your pot at once continuing to cook on high heat and stirring the mixture with a spatula continuously until a dough starts to form and a thin film appears at the base of the pot. This should take 3-5 minutes and the dough should reach 175F.
82 g Bread Flour, ⅓ teaspoon Salt
Place the dough into the bowl of a stand mixer and using a paddle attachment, start to mix in order to cool down the dough to 145F.
Add eggs to the choux dough one at a time, continuously mixing with the paddle attachment. You'll know that your dough is at the right consistency when the dough forms a V-shape as it hangs off the spatula and/or paddle attachment.
130 g Eggs
Transfer the choux dough to a piping bag and snip off the tip of the bag to create a ½ inch opening.
Pipe one-inch rounds of dough onto a parchment-lined baking sheet leaving space between each cream puff - two to three inches. Leave at least 3 inches in between each dollop for when the choux will begin to inflate (about 6 on each baking sheet).
Take the frozen cream puff craquelin out of the freezer and use a 2-inch round cutter to cut circles of crust out. Then, gently place one disc on top of your piped batter.
Place the cream puffs into the oven baking for 5 minutes before turning down the temperature to 350°F for an additional 25 minutes or until browned. Then, crack the oven and allow the choux to cool naturally within the oven for about 20 minutes.
