Key Ingredients:
I’ve included everything below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the Recipe card at the bottom of this post.
- Almond flour. Provides a nutty base and sturdy structure for the low-carb choux pastry. It mimics traditional flour textures brilliantly while keeping carbs low.
- Erythritol sweetener. Delivers clean, sugar-free sweetness to both the pastry and custard. It dissolves smoothly without leaving any chemical aftertaste.
- Eggs. Act as the primary leavening agent for the choux pastry while enriching the custard. They create those signature hollow pockets and golden peaks.
- Heavy cream. Forms the luxurious, velvety backbone of the cooked vanilla custard. It ensures a rich, mouth-watering consistency.
- Butter. Adds essential moisture and rich flavor to the pastry dough. It guarantees a tender crumb with crisp edges.
- Vanilla extract. Infuses the sweet custard with warm, aromatic fragrance. It elevates the classic European bakery taste.
How to Make Keto Karpatka
I’ve included everything below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the Recipe card at the bottom of this post.
- Preheat your oven to 180°C (350°F) and line two baking pans with parchment paper. Next, melt butter and water in a saucepan over medium heat until simmering gently.
- Stir almond flour and coconut flour into the hot butter mixture vigorously for 2 minutes until a dough ball forms. Remove from heat and let it cool slightly.
- Beat eggs into the warm dough one at a time using a hand mixer until smooth and glossy. Spread half the batter unevenly onto each prepared pan to create mountain peaks.
- Bake for 25 minutes until golden brown and puffed, then turn off the oven and let them dry inside. Meanwhile, whisk egg yolks, sweetener, and plant milk in a saucepan over medium-low heat until thick.
- Whip heavy cream until stiff peaks form and fold it gently into the cooled custard base. Spread the rich vanilla cream evenly over the bottom pastry layer.
- Top with the second baked pastry sheet and chill in the refrigerator for at least 4 hours until set. Finally, dust with powdered erythritol before slicing and serving.
- Pro Tip: Let the custard cool completely before folding in whipped cream to prevent the mixture from melting.
Common Mistakes to Avoid:
- Adding eggs while the dough is boiling will scramble them instantly.
- Opening the oven door too early causes the choux pastry to deflate flat.
- Skipping the chilling time results in a runny custard that slides apart.
Required Equipment:
- Baking pans — provide a flat surface for baking even pastry layers.
- Hand mixer — beats eggs and whips heavy cream efficiently.
- Saucepan — cooks the thick, velvety vanilla custard evenly.
- Parchment paper — prevents sticky choux dough from burning or tearing.
Caleb’s Recipe Tips
- Whip your heavy cream until very stiff before folding to maintain a fluffy custard texture.
- Add a tiny pinch of salt to the pastry dough to balance the rich sweetness.
- Chill the assembled cake overnight to let the layers soften into a cake-like harmony.
- Use room-temperature eggs so they incorporate smoothly into the warm choux batter.
- Dust the top generously with powdered sweetener right before serving for a snowy effect.
Storage Instructions
- Refrigerator storage keeps the cake fresh inside an airtight container for up to 4 days.
- Freezer storage works for individual slices wrapped tightly for up to 1 month.
- Containers should be airtight to prevent the pastry from absorbing fridge odors.
- Reheating tips are unnecessary because this traditional dessert tastes best served cold.

Ingredients
