Directions

1. Prep + Mise en Place (5 minutes)
   1. Preheat your oven to 350°F (175°C). Line a 9x13-inch baking pan with parchment paper, leaving an overhang on the long sides to easily lift the cake layers.
   2. If using, toast the walnuts for the cake layers and filling in a dry skillet over medium heat for 3-5 minutes until fragrant. Let cool completely, then finely grind the portion for the cake and chop the portion for the filling.
2. Make One Sponge Batter, Then Split Into 3 Flavors
   1. In a large, clean bowl, whisk the egg whites with an electric mixer until soft peaks form. Gradually add 1/2 cup (100g) of the granulated sugar, continuing to whisk until stiff, glossy peaks form. Set aside.
   2. In a separate bowl, whisk the egg yolks with the remaining 1/2 cup (100g) sugar until pale yellow and thick.
   3. Gently fold about one-third of the whipped egg whites into the yolk mixture to lighten it, then fold in the remaining egg whites until just combined.
   4. Sift the flour and salt over the egg mixture and gently fold until no streaks of flour remain. Be careful not to deflate the batter.
   5. Divide the batter evenly into three separate bowls (approximately 1 cup each).
   6. To the first bowl, gently fold in the cocoa powder until just combined (Cocoa Layer).
   7. To the second bowl, gently fold in the finely ground walnuts until just combined (Walnut Layer).
   8. Leave the third bowl plain (Vanilla Layer).
3. Bake the Layers Sequentially in the Same Pan
   1. Pour the Vanilla Layer batter into the prepared 9x13-inch pan and spread evenly. Bake for 8-10 minutes, or until the center springs back when lightly touched and the edges are lightly golden.
   2. Carefully remove the vanilla layer from the pan by lifting the parchment paper. Place it on a wire rack to cool slightly.
   3. Repeat the process with the Cocoa Layer, baking for 8-10 minutes. Remove and cool.
   4. Finally, bake the Walnut Layer for 8-10 minutes. Remove and cool.
   5. Quick Cool Method: To speed up cooling, you can place the warm cake layers (still on parchment) in the refrigerator for 10-15 minutes.
4. Make the Rum Syrup
   1. In a small saucepan, combine water and sugar. Bring to a simmer over medium heat, stirring until the sugar dissolves completely. Remove from heat.
   2. Let the syrup cool for 5-10 minutes, then stir in the dark rum and optional citrus zest. Set aside. The syrup should be cool or lukewarm when used, not hot.
5. Make the Vanilla Custard-Cream (Lump-Free)
   1. In a medium saucepan, whisk together the egg yolks, cornstarch (or flour), and sugar until smooth.
   2. Gradually whisk in the milk until fully incorporated. If using a vanilla bean, add it now.
   3. Cook over medium-low heat, whisking constantly, until the mixture thickens significantly and comes to a gentle boil, about 8-10 minutes. It should be thick enough to coat the back of a spoon.
   4. Remove from heat. If using vanilla bean, remove it and scrape in the seeds. Stir in the vanilla extract.
   5. For a perfectly smooth custard, pass it through a fine-mesh sieve into a clean bowl.
   6. Cover the surface directly with plastic wrap to prevent a skin from forming and chill in the refrigerator until completely cold, at least 2 hours.
   7. Optional: Once the custard is cold, gently fold in 1/2 cup of whipped heavy cream for a lighter, creamier texture.
6. Make the Chocolate Sauce
   1. In a small saucepan, combine the chopped chocolate, cocoa powder, water (or cream), and sugar.
   2. Heat over low heat, stirring constantly, until the chocolate is melted and the sauce is smooth and glossy. Do not boil.
   3. Remove from heat and stir in the optional rum. Keep warm or gently reheat before serving. The sauce should be pourable but not watery.
7. Assemble the Dessert (Layers That Actually Hold)
   1. Gently warm the apricot preserves in a small saucepan or microwave until spreadable.
   2. Place the Walnut Layer on the bottom of your serving dish or a 9x13-inch pan (if assembling in the pan). Brush generously with about one-third of the rum syrup. The cake should feel moist, but not soggy.
   3. Spread half of the chilled vanilla custard over the walnut layer.
   4. Sprinkle half of the raisins and half of the chopped toasted walnuts over the custard.
   5. Place the Cocoa Layer on top, press gently, and brush with another third of the rum syrup.
   6. Spread the remaining half of the vanilla custard over the cocoa layer.
   7. Sprinkle the remaining raisins and chopped toasted walnuts.
   8. Top with the Vanilla Layer, press gently, and brush with the remaining rum syrup.
   9. Spread the warmed apricot preserves thinly and evenly over the top vanilla layer.
   10. Dust lightly with unsweetened cocoa powder.
   11. Cover the dish tightly with plastic wrap.
8. Chill (Non-Negotiable)
   1. Refrigerate the assembled Somlói Galuska for a minimum of 6 hours, but ideally overnight (12-24 hours). This chilling period is crucial for the flavors to meld and the cake to fully absorb the syrup, resulting in the perfect texture.
