Step-by-Step Instructions
- Prepare the Sponge Cake:
- Begin by buttering and flouring a rectangular cake pan then heat the oven to the right temperature. Whisk the eggs with sugar until the mixture is pale thick and doubled in volume – this takes patience but is crucial for structure. Gradually blend in honey vanilla lemon zest and salt without deflating the batter. Gently fold in sifted flour with a spatula until no streaks remain being careful not to overmix. Pour the batter into your prepared pan and bake until golden and springy then fully cool before handling.
- Bake the Puff Pastry:
- Roll out the chilled puff pastry sheets to even rectangles for neat layers. Prick the sheets all over with a fork to prevent excessive puffing and transfer to parchment-lined baking sheets. Bake one at a time in the center of the oven until crisp and richly golden checking in the final minutes to avoid burning. Allow to cool completely on a rack before assembling.
- Prepare the Creme Diplomático:
- Whisk egg yolks with sugar until creamy then add both starches for thickening. Slowly heat whole milk with vanilla and temper into the yolk mixture to form a classic pastry cream. Cook gently while stirring until luscious and thick. Cool then fold in softly whipped heavy cream for a silky diplomat blend. Chill well until firm and spreadable.
- Make the Syrup:
- Bring water and sugar to a boil in a small pot stirring until dissolved. Let cool before adding Alchermes liqueur or your preferred syrup for a floral pink touch. Store covered in the refrigerator until needed.
- Assemble the Cake:
- Trim cooled pastry and sponge cake to matching rectangles using a sharp knife for a polished appearance. On your serving platter spread a dab of cream to anchor the bottom shell. Lay down the first pastry layer and top with a thick blanket of Creme Diplomático spreading edge to edge. Gently brush the sponge cake with syrup until well-moistened both sides and place with the syrup side down atop the cream. Repeat a brush of syrup on the top then follow with another layer of cream. Complete the stack with the final puff pastry layer pressing lightly for contact. Chill for several hours so the flavors marry and the cake slices cleanly.
- Finish and Serve:
- Just before serving sift powdered sugar liberally over the top for a classic finish. Slice with a serrated knife and use a spatula to lift each portion for the best presentation.

Nothing brings me back to family birthdays like that first forkful the fragrance of lemon and vanilla always signals celebration in my childhood memories. The delicate layers speak of hours of love yet the method is truly approachable with good organization.
Storage tips
Store leftover cake tightly covered in the refrigerator to preserve freshness and texture. It keeps well for up to three days although the pastry will soften lightly over time. For best results cut only the slices you will serve and leave the rest chilled and whole.
Ingredient substitutions
If you cannot find Alchermes liqueur try kirsch raspberry syrup or even a homemade cherry simple syrup for the syrup layer. For the diplomat cream you can use store-bought vanilla pudding blended with whipped cream in a pinch though homemade shines brightest. Gluten-free all-purpose flour works for the sponge but ensure your puff pastry is gluten-free too.
