Cream puffs with custard filling recipe| Tools to use

There is one item which is crucial for this recipe. That is “Silicone Mini Cupcake Holders,” which you can find on amazon. This mold is reusable and refusable.

>> Mini Cupcake Holders

Unfortunately, without this holder, you cannot make the petite puffs with this recipe. This mold enables the puffs inflate like balloons.

You can try other other size, but the possibility to be deflated will increase with bigger size. This mini holders are the best among all the holders.

Cream puffs with custard filling recipe| Ingredients

There is one ingredient which you may not have in your kitchen.

That is “Kinako powder”. This ingredient has been used in Japan for a long time.

Ketogenic? Yes, it is.

Choux puff

This is two times amount of the the recipe.
  • Heavy Cream

  • Kinako Powder (It adds crunchy savory flavor to the puff. But you may eliminate it if it is hard to obtain.)

  • Egg

Yes, surprisingly, these are the only items that you need to make these cream puffs!

“Kinako powder” is flour made by soybeans. This product has been used forever in Japan for rice cakes, ice creams etc. It tastes a bit like nuts. However as it has very light tastes, it can be used for various kinds of meals.

>> Kinako Soy Bean Flour

I am from Japan and I love this flour. My favorite thing to use the flour is sticky rice cake. People often eat rice cake with Kinako flour in Japan. It goes very well with some sweet sauce.

As I am on ketogenic diet and staying away from rice, I am making “soy milk rice cake made by psyllium husk” these days. I would like to introduce the recipe later.

Custard cream

  • Egg

  • Heavy Cream

  • Whole earth

  • Vanilla Extract

I personally like the combination of Custard cream and whipped heavy cream… It is just perfect to have them together with 1:1 on any sweet.

Cream puffs with custard filling recipe|How to make it

Basically, all you have to do is mixing all the ingredients and use an oven and a microwave. The puff will be gradually inflating in the oven.

Choux puff

1 Set the oven temperature to 400F(200c).

2 Put the 15ml of heavy cream and Kinako powder in a bowl and whisk till you do not see the powder in it anymore.

3 Put the an egg in the bowl and whisk till all gets mixed well. DO NOT whisk too much.

4 Put 3 to the holders.

5 Put them in the upper section in the oven, only after the oven reached the designated temperature. Bake for 15 minutes.

Do not open the oven while baking it or even after 15 minutes. Puffs will be deflated when it is suddenly exposed to cold air.


Only after everything will be cooled down in the oven, you can take them out.

6 Turn off the oven after 15 minutes. Do NOT OPEN the door of the oven soon. Leave the puffs in the oven for 2 to 3 hours till they cool down.

7 Take the puffs out of the oven.

8 Cut the upper 1/3 of the puff to make a cup.

9 Put any kind of filling as you want.

My favorite is Custard cream, chocolate whipped heavy cream, and normal whipped heavy cream.

Some cocoa powder is sprinkled on them.

It’s small so that you can eat them in one bite!

Let’s make Cream puffs with custard filling!

What is amazing is that you can make 10 puffs out of an egg with this recipe.

Think about it, If you order three pieces of these puffs at a restaurant, how much do you have to pay? Most probably, you will pay six to ten dollars! You are served only 1/3 of an egg with the dish.

I just found this recipe couple of days ago, and I have been making them almost everyday since then!

It is too good….so be careful, don’t eat them too much!
