Ingredients You’ll Need

Ingredient

This list covers the choux and the pastry cream.

• 1 cup water
• 1/2 cup unsalted butter
• 1 cup all-purpose flour
• 4 large eggs
• 1/4 teaspoon salt
• 2 cups milk
• 1 cup sugar
• 1/4 cup cornstarch
• 4 large egg yolks
• 1 teaspoon vanilla extract
• Powdered sugar for dusting

Use full-fat milk for a richer cream; skim makes it weak.

How to Make (Step-by-Step)

Method

Follow the numbered steps for timing and order; patience matters.
Keep your whisk ready and clean bowls handy.
Sound like a lot? It’s not, promise.

STEP 1

Preheat the oven to 400°F (200°C).

STEP 2

In a saucepan, combine water and butter. Bring to a boil.

STEP 3

Stir in flour and salt, and mix until a ball forms.

STEP 4

Remove from heat and let cool for a few minutes.

STEP 5

Beat in eggs one at a time until the mixture is smooth.

STEP 6

Divide the dough into two equal parts. Spread each part onto a greased baking sheet.

STEP 7

Bake for about 25-30 minutes until golden brown and puffed.
Let the shells cool upside down on a rack to avoid sogginess.

STEP 8

Meanwhile, make the pastry cream: In a saucepan, combine milk and sugar.

STEP 9

In a bowl, whisk together cornstarch and egg yolks.

STEP 10

Gradually add the hot milk mixture to the egg mixture, whisking constantly.

STEP 11

Return to the saucepan and cook over medium heat until thickened.
Stir constantly; lumps ruin the vibe.

STEP 12

Stir in vanilla extract and let cool.

STEP 13

Once the pastry layers are cool, spread the pastry cream between them.
Layer gently to keep those cute peaks intact.

STEP 14

Dust with powdered sugar and serve.

Pro Tips for the Best Results

• Dry choux centers are a no-no: cool shells fully before slicing or you’ll squish the steam.
• Eggs at room temp mix in better; trust me, I tried cold ones and cursed quietly.
• Don’t open the oven early; let the choux puff up fully or you’ll deflate the drama.
• Make pastry cream ahead to let flavors marry; it actually gets better after a few hours.
• Experiment with extracts: a splash of rum or almond takes it up a notch.
• If you want crispier tops brush with beaten egg before baking.

I once forgot cornstarch and learned the hard custard way — don’t do that.

Fun Variations & Topping Ideas

Variations:

• Coffee pastry cream: dissolve espresso in milk before heating.
• Lemon twist: fold in lemon zest and a touch of lemon juice.
• Chocolate layer: sprinkle cocoa into the cream or add a ganache.

Which one will you try first? IMO, coffee filling pairs amazingly with a chocolate drizzle.

Toppings:

• Powdered sugar classic, but try toasted almonds for crunch.
• Fresh berries add color and brightness.
• Chocolate shavings make it look like you spent hours on it (lie politely).

Storing and Reheating

Store this cake covered in the refrigerator for up to 3 days.
The pastry cream likes cold, so don’t expect it to be as dreamy at room temp after long storage.
If you want to serve it slightly warmer, let it sit 20 minutes at room temperature before slicing.
You can refrigerate shells and cream separately to keep crunch.
Warm slices in a low oven for five minutes if you want warm cream without melting.

Leftover ideas

Turn slices into parfaits by spooning leftover cream and tearing choux into a bowl with fruit.
FYI, the cream makes an awesome filling for donuts or crepes, if you wake up feeling extra ambitious.
Chop leftover choux and toss with ice cream for instant texture.
Pair slices with a savory main like this cracked garlic steak tortellini in creamy sauce for dinner that ends on a sweet note.

Frequently Asked Questions (FAQ)

Is Karpatka hard to make?

Not at all. The techniques are simple: choux dough and pastry cream, both forgiving if you follow steps.

Can I freeze this cake?

I don’t recommend freezing assembled Karpatka; the cream changes texture. Freeze unfilled choux separately for up to one month.

Can I use store-bought pastry cream?

Yes, but homemade tastes brighter. If short on time, buy a high-quality custard and add a splash of vanilla to boost flavor.

What’s the origin of Karpatka?

Polish bakers popularized Karpatka; the name nods to the Carpathian Mountains because the choux peaks look like mountain ridges. Cute, right?

How do I fix runny pastry cream?

Cook a bit longer; add a slurry of cornstarch and cold milk, then simmer until thick.

Can I make mini Karpatka?

Absolutely. Pipe smaller rounds, reduce bake time slightly, and you get cute individual desserts that vanish fast.
