Please refer toWhipped Custard Cream and make enough to make 15 when making the custard cream. Or, use your favorite cream.

Sift the cake flour. Dissolve the eggs so that there are no inconsistencies. Spread out cooking paper on a cookie sheet. Preheat the oven to 190°C.

Add water, butter, and vegetable oil to a pot, bring to a full boil over a high heat, and then remove from the heat. I don't use salt or granulated sugar).

Do this quickly: add in the cake flour once, and knead well with a wooden spatula until the whiteness (clumps) disappear.

Turn on over a low heat and knead while mixing once more for 20 seconds. (The eggs will fry if you add too much at a time while mixing, so be careful).

Add in about one whole eggs worth of a lightly whisked egg, and knead while mixing. After that, add in bit by bit while checking it. (3 eggs is more than enough).

Lift up the batter with a spatula, and let it fall back down to the original dough. It will fall off in a triangular shape and stop once it accumulates but before falling off the side.

Place the batter into a pastry bag, and squeeze it out into 4 cm sizes with space between each. Dip your fingers in water, and then lightly press down on the batter to flatten it out.

Then, gently stick in four places with a toothpick vertically. (This is to get it to break apart cleanly.. You don't have to do this).

Spray the batter all over, and set into the oven. First bake for 20 minutes at 190°C for 20 minutes, reduce the temperature to 180°C, and bake for another 15 minutes.

Let it sit in he oven for 5~10 minutes in the residual heat inside the oven instead of taking them out immediately, and then take them out.

Squeeze the cream in. You can cut in little notches for the cream. Cover with powdered sugar to preference, and it's done.

When you cut into these: they are crispy and crunchy. They have quite a lot of cream filling!

The photo for Step 11 has been cooked golden brown. This was baked at 200°C for 20 minutes, reduced to 190°C, and then cooked well until golden brown for 15 minutes. Please bake whichever way you like.
