Step-by-Step Instructions
Step 1: Prepare your equipment and ingredients
Heat the oven to 320°F (160°C), conventional setting, with racks in the upper and lower thirds. Draw one eight-inch (20 cm) circle on each of five sheets of parchment paper. Turn the parchment over so the pencil marks cannot touch the batter. Have two baking sheets ready; you will reuse them between batches.
Use a digital scale to divide the cake ingredients into the three batches listed above. If grinding whole walnuts, pulse them briefly in a food processor until finely ground, stopping before they become oily or pasty. Set out a stand mixer or electric hand mixer, a small offset spatula, a piping bag with a very small opening, and a thin wooden skewer.
Step 2: Cook and cool the vanilla custard
Whisk the egg yolks, 100 g granulated sugar, cornstarch, and salt in a medium heatproof bowl until smooth. The mixture will be thick.
Heat the milk in a saucepan over medium-low heat for approximately 5 minutes, until steaming. Slowly whisk about one-third of the hot milk into the yolk mixture, then return everything to the saucepan. Cook over medium heat, whisking constantly, for approximately 2 minutes, until thick and bubbling. Once it reaches a gentle boil, continue whisking and cooking for 1 full minute to cook the starch thoroughly.
Transfer the custard to a shallow dish and press food-safe wrap directly onto its surface. Cool for approximately 45 minutes, until it reaches 68–72°F (20–22°C). If needed, set the dish over an ice bath to finish cooling. The custard and butter must be at similar temperatures before mixing; do not leave the custard unrefrigerated for more than 2 hours.
Step 3: Whip the first batch of walnut meringue
For the first two-layer batch, place 96 g egg whites and 1/2 teaspoon lemon juice in a clean, grease-free mixing bowl. Beat on medium speed for 2 minutes, until foamy and beginning to hold soft peaks.
Increase to medium-high speed and gradually add 80 g granulated sugar over 2 minutes. Continue beating for approximately 2 minutes, until the meringue is glossy and forms stiff peaks that stand upright when the beaters are lifted.
Gently fold in 100 g ground walnuts in two additions, using a wide spatula and lifting from the bottom of the bowl. Stop as soon as no dry pockets remain. Divide the batter equally between two prepared parchment circles, one on each baking sheet, and spread it evenly to the drawn edges.
Step 4: Bake all five thin cake layers
Bake the first two layers for 22 minutes, swapping the baking sheets between racks and rotating them front to back after 11 minutes. The layers should be lightly golden, dry on top, and firm around the edges, with a center that feels set rather than wet.
Slide the parchment sheets onto cooling racks. Let the baking sheets cool for 5 minutes before adding fresh parchment. Make the second two-layer batch exactly as in Step 3 and bake for another 22 minutes.
For the final layer, repeat the same whipping and folding method with 48 g egg whites, 1/4 teaspoon lemon juice, 40 g sugar, and 50 g ground walnuts. Bake this single layer on the middle rack for 22 minutes. Making each batch just before baking prevents the walnut meringue from deflating while it waits.
Cool each baked layer on its parchment for at least 20 minutes. To remove the paper, carefully turn a layer over, support it with your hand or a flat board, and peel the parchment away from the cake rather than pulling the cake upward. Reserve the flattest layer for the top.
Step 5: Make the silky vanilla buttercream
Beat the softened butter on medium-high speed for 5 minutes, until pale and fluffy. Check that the cooled custard and butter are both approximately 68–72°F (20–22°C).
With the mixer running on medium speed, add the custard a spoonful at a time over approximately 5 minutes. Scrape down the bowl, add the vanilla, and beat for 1 minute more, until smooth and creamy. The finished buttercream should spread easily while holding its shape.
Step 6: Stack the torte and coat the sides
Place one walnut layer on a flat serving plate or cake board. Reserve 160 g buttercream for the sides, then divide the remaining buttercream into four equal portions.
Spread one portion over the first layer, right to the edge. Continue stacking and filling until all five cake layers are in place, finishing with the flattest layer on top. Press very gently to level the stack without squeezing out the filling.
Spread the reserved buttercream thinly around the sides, leaving the top bare. Press the 60 g chopped walnuts onto the buttercream-coated sides. Refrigerate the assembled torte for 30 minutes.
Step 7: Add the pale glaze and feathered chocolate pattern
Warm the apricot jam with 1 teaspoon water in a small saucepan over low heat for 1 minute, stirring until fluid. Let it cool for 5 minutes, then brush a thin, even coating over the bare top layer.
Melt the dark chocolate and neutral oil in a microwave-safe bowl in 15-second bursts, stirring between each burst, until smooth. Transfer to a small piping bag and snip an opening approximately 1 mm wide. Have your skewer ready before mixing the glaze.
Stir the sifted confectioners’ sugar with the hot water and lemon juice until smooth. It should fall from the spoon in a thick ribbon. Immediately pour it onto the center of the cake and spread quickly into an even layer, just reaching the edge.
While the glaze is still wet, pipe five thin concentric chocolate circles over the top. Drag the skewer through the circles along 16 evenly spaced radial lines, alternating from the center outward and from the edge inward. Wipe the skewer clean after every pass. Work promptly: the fine feathered pattern depends on both the icing and chocolate remaining fluid.
Step 8: Chill, slice, and serve
Refrigerate the decorated torte for 5 hours 30 minutes, giving it a total of 6 hours of chilling. This rest allows the filling to settle and the thin walnut layers to soften into a tender, sliceable cake. For even better texture, refrigerate overnight.
Remove from the refrigerator 20 minutes before serving. Cut into 12 slices with a sharp knife dipped in hot water and wiped dry between cuts. Use a gentle sawing motion through the glazed top, then press down through the layers.
Pro Tips
- Weigh the egg whites: Egg sizes vary, and precise portions help all five layers bake evenly.
- Keep the walnuts fine, not oily: Nut paste is heavy and can collapse the meringue. Short food-processor pulses are best.
- Match buttercream temperatures: If the mixture looks curdled and feels cold, warm the outside of the bowl briefly with a warm towel while beating. If it looks loose and greasy, refrigerate for 10 minutes, then beat again.
- Decorate without pausing: Melt the chocolate and prepare the piping bag before spreading the glaze. Once the glaze forms a skin, the skewer will drag instead of feathering cleanly.
- Give the torte its resting time: Freshly assembled layers can be brittle; chilling transforms them into the delicate, cohesive texture this cake is known for.
Variations
- Hazelnut Esterházy torte: Replace the 250 g ground walnuts and 60 g chopped walnuts with the same weights of finely ground and chopped blanched hazelnuts.
- Rum-scented buttercream: Reduce the custard milk to 285 ml. Beat 1 tablespoon (15 ml) dark rum into the finished buttercream along with the vanilla.
- Mixed-nut layers: Use 125 g finely ground walnuts and 125 g finely ground blanched almonds in the cake layers, keeping the remaining ingredients unchanged.
Storage & Make-Ahead
Refrigerate: Keep the finished torte covered in the refrigerator at 40°F (4°C) or below for up to 3 days. Use a tall cake container so the covering does not touch the glaze. Avoid leaving the cake at room temperature for more than 2 hours.
Prepare components ahead: Bake the walnut layers up to 1 day ahead and store them flat, separated by parchment, in an airtight container at cool room temperature. Make the custard up to 2 days ahead and refrigerate with wrap touching the surface; bring it to 68–72°F (20–22°C) before making the buttercream. Assembling the entire torte the day before serving gives excellent results.
Freeze: Freeze individual slices in airtight containers for up to 1 month. Thaw overnight in the refrigerator. The glaze may lose some shine, but the flavor and layered texture will remain lovely.
