Ingredients

For the choux pastry layers (dough)

• 150 g all-purpose flour (≈1 + ½ cup)
• 100 ml water (≈½ cup)
• 100 ml milk (≈½ cup)
• 80 g unsalted butter (≈⅓ cup)
• 4 medium eggs (room temperature)
• 1 tsp baking powder
• ½ tsp salt

For the light custard cream

• 500 ml milk (whole or semi-skimmed)
• 150 g sugar (or 120–130 g stevia/erythritol blend for lower calories)
• 100 g cornstarch (≈1 cup)
• 2 large eggs
• 1 tsp vanilla extract or vanilla sugar
• Optional: 50–80 g butter (for richer version — omit for lighter)

To finish

• Icing sugar or powdered sweetener for dusting
• Optional: extra lemon zest or a few fresh berries for decoration

Step-by-Step Instructions

1. Make the light custard cream (can be done ahead)

1. In a medium saucepan off the heat, whisk the eggs, sugar (or sweetener), cornstarch, and vanilla until completely smooth and lump-free.
2. Gradually pour in the milk while whisking constantly to avoid lumps.
3. Place the pan over medium-low heat.
4. Cook, stirring constantly with a whisk, until the mixture thickens and starts to bubble gently (≈6–10 minutes). It should look like a thick pudding.
5. Once thickened, remove from heat.
6. If using butter, stir it in now until fully melted and incorporated.
7. Transfer to a shallow bowl, press cling film directly onto the surface (to prevent skin forming), and let cool to room temperature, then refrigerate until completely cold (at least 1–2 hours).

2. Prepare the choux pastry layers

1. Preheat oven to 200°C (390°F) static (top & bottom heat, no fan).
2. Line two 18–20 cm (7–8 inch) springform pans (or regular round pans) with parchment paper — no need to grease if using good paper.
3. In a medium saucepan, combine water, milk, butter, salt, and a pinch of sugar (or sweetener). Bring to a rolling boil over medium heat.
4. As soon as it boils, remove from heat and immediately add all the flour + baking powder at once.
5. Stir vigorously with a wooden spoon or spatula until the mixture forms a smooth ball and pulls away from the sides (≈1–2 minutes).
6. Transfer dough to a large bowl and let cool for 5–10 minutes (should be warm but not hot).
7. Add eggs one at a time, beating well after each addition with a spatula or electric mixer until smooth and glossy. The dough should be thick but pipeable.
8. Divide the dough evenly between the two prepared pans.
9. Spread into an even layer (≈1 cm thick) — it doesn’t have to be perfectly round; it will puff irregularly (that’s the traditional Karpatka look!).
10. Bake both layers at 200°C (390°F) for 18–22 minutes until golden and puffed.
11. Do not open the oven door during baking — they may collapse.
12. Remove and cool completely on a wire rack (they will deflate — that’s normal).

3. Assemble the cake

1. Place one cooled pastry layer on a serving plate or cake stand (use the springform ring if you want clean edges).
2. Spread the completely cooled custard cream evenly over the layer — go right to the edges.
3. Gently place the second pastry layer on top.
4. Press lightly so it adheres.
5. Cover with cling film and refrigerate for 2–3 hours (or overnight) so the cream sets and flavors meld.

4. Finish & serve

1. Remove cling film and springform ring (if used).
2. Dust generously with icing sugar or powdered sweetener.
3. Optional: sprinkle extra lemon zest or decorate with fresh berries.
4. Slice with a sharp knife (wipe between cuts for clean slices).
5. Serve chilled or at cool room temperature.
