Full Ingredients
Equipment: A 9 × 5 × 3-inch metal loaf pan, baking parchment, mixing bowls, a small saucepan, a whisk, a flexible spatula, a cooling rack, and a long serrated knife. Weighing the flour and sticky sweeteners gives the most consistent results.
For the Gingerbread Cake
- 250 g all-purpose flour, about 2 cups, spooned and leveled
- 25 g unsweetened natural cocoa powder, about 1/4 cup
- 1 teaspoon baking powder, 4 g
- 1/2 teaspoon baking soda, 2.5 g
- 1/2 teaspoon fine salt, 3 g
- 2 teaspoons ground cinnamon
- 1 1/2 teaspoons ground ginger
- 1/2 teaspoon ground cloves
- 1/4 teaspoon ground nutmeg
- 115 g unsalted butter, about 1/2 cup, cut into pieces
- 100 g dark brown sugar, about 1/2 cup packed
- 170 g honey, about 1/2 cup
- 60 g unsulphured molasses, about 3 tablespoons; not blackstrap
- 2 large eggs, at room temperature
- 120 ml whole milk, 1/2 cup, at room temperature
- 1 teaspoon vanilla extract, 5 ml
For the Plum Filling
- 300 g thick, tangy plum or prune preserves, about 1 cup, at room temperature; preferably powidła śliwkowe
Choosing the filling: Look for a thick plum spread with a pleasantly tart flavor. Powidła śliwkowe is a concentrated Polish plum preserve, often made with little or no added sugar. Avoid a loose, syrupy jam, which can seep into the cake and make the layers slide.
For the Dark Chocolate Glaze and Nut Topping
- 170 g 70% dark chocolate, 6 ounces, finely chopped
- 120 ml heavy cream, 1/2 cup, with 35–36% milk fat
- 14 g unsalted butter, 1 tablespoon, softened
- 40 g walnuts, about 1/3 cup, chopped into small pieces
Step-by-Step Instructions
Step 1: Prepare the oven, pan, and dry ingredients
Heat the oven to 350°F (175°C), or 320°F (160°C) fan, with a rack in the middle. Line the base and sides of a 9 × 5 × 3-inch metal loaf pan with parchment, leaving enough overhang on the long sides to lift out the cake.
In a large bowl, whisk together the flour, cocoa powder, baking powder, baking soda, salt, cinnamon, ginger, cloves, and nutmeg. Break up any cocoa lumps so the spices and leavening are evenly distributed.
Step 2: Warm the honey and molasses mixture
Put the 115 g cake butter, dark brown sugar, honey, and molasses in a small saucepan. Warm over low heat for 5 minutes, stirring frequently, until the butter has melted and the mixture looks smooth. Do not let it boil.
Remove from the heat and cool for 15 minutes, stirring once or twice. It should feel lukewarm, not hot; if using a thermometer, aim for 104°F (40°C) or cooler before adding it to the eggs.
Step 3: Mix the cake batter
In a separate bowl, whisk the eggs, milk, and vanilla until combined. Slowly whisk in the cooled honey mixture.
Pour the wet ingredients into the dry ingredients. Fold gently with a spatula, scraping the bottom and sides of the bowl, just until no dry flour remains. The batter will be thick but pourable. Scrape it into the prepared pan and smooth the surface.
Step 4: Bake the cake and toast the walnuts
Bake for approximately 65 minutes, beginning to check at 60 minutes. The center should spring back lightly, and a skewer inserted into the middle should come out clean or with a few moist crumbs, but no wet batter. If necessary, continue baking in 5-minute increments. If the top is getting too dark, loosely cover it with foil after 45 minutes.
During the final 8 minutes of baking, spread the walnuts on a separate small baking tray and place them in the oven. Stir after 4 minutes and remove when fragrant and lightly golden. Let them cool completely.
Step 5: Cool the cake completely
Leave the cake in its pan for 15 minutes. Lift it out using the parchment, peel the paper away from the sides, and place it on a cooling rack for approximately 1 hour 45 minutes, until completely cool.
Do not rush this stage: a warm cake is more likely to crumble during slicing, and warm layers can soften the filling. If your kitchen is warm, allow extra cooling time.
Step 6: Slice and fill the layers
Place the cooled cake on a cutting board. Using a long serrated knife, make two horizontal cuts to divide it into 3 even layers. If the top is very domed, shave off just enough to make it stable; a gently rounded top is perfectly fine.
Set the bottom layer on a serving platter. Stir the preserves until spreadable, then spread 150 g evenly over the cake, stopping about 1/4 inch (6 mm) from the edges. Add the middle layer, spread with the remaining 150 g preserves, and replace the top. Press down very gently to settle the layers without squeezing out the filling.
Step 7: Make the glossy chocolate glaze
Put the finely chopped chocolate in a dry, heatproof bowl. Warm the cream in a small saucepan over medium-low heat for 3–5 minutes, until steaming with tiny bubbles around the edge, but not boiling vigorously.
Pour the cream over the chocolate and leave undisturbed for 3 minutes. Stir gently from the center outward until smooth, then stir in the 14 g softened butter. Avoid vigorous whisking, which can introduce bubbles. Let the glaze cool for approximately 10 minutes, stirring occasionally, until it pours in a thick ribbon rather than running like water.
Step 8: Glaze, decorate, and let set
Tuck strips of parchment just under the cake edges to protect the platter. Pour the glaze over the top, using a small spatula to ease it toward the edges so it drapes naturally down the sides. Scatter the toasted walnuts over the top while the glaze is still soft.
Let stand for 1 hour in a cool room, ideally 64–70°F (18–21°C), until the glaze is softly set. Remove the parchment strips. For neat slices, use a sharp knife dipped in hot water and wiped dry between cuts. Refrigerate any cake that will not be served within 2 hours.
Pro Tips
- Use regular molasses: Blackstrap molasses is much more bitter and can overwhelm the honey and delicate plum filling.
- Measure flour lightly: Too much flour is the quickest route to a dry piernik. Use 250 g, or spoon flour into your measuring cup without packing it.
- Keep the filling thick: If your preserves are runny, simmer them gently for 5–10 minutes to reduce, then cool completely and measure out 300 g before filling.
- Give the cake an overnight rest: Cover and refrigerate the finished cake overnight for softer layers and a more rounded spice flavor. Let individual slices stand at room temperature for 30 minutes before serving.
- Glaze at the right consistency: If the glaze runs off too quickly, let it cool for another 5 minutes. If it becomes too thick, stir the bowl briefly over warm water.
Variations
- Orange-scented piernik: Add 2 teaspoons finely grated orange zest to the wet ingredients for a bright citrus note alongside the honey and spices.
- Prune filling from scratch: Simmer 200 g pitted prunes with 180 ml water for 12–15 minutes, until very soft. Blend with 15 ml lemon juice, cool, and use 300 g of the thick purée between the layers.
- Different nuts or nut-free: Replace the walnuts with 40 g chopped hazelnuts, toasted at 350°F (175°C) for 8–10 minutes and rubbed in a towel to remove loose skins. For a nut-free version, omit the nuts and check all ingredient labels as needed.
Storage & Make-Ahead
Refrigeration: Because the glaze contains cream, keep the finished cake covered in the refrigerator at 40°F (4°C) or below for up to 5 days. Let slices stand at room temperature for 30 minutes before serving. Keep total unrefrigerated serving time within 2 hours.
Make ahead: Bake the unfilled cake up to 1 day ahead; cool completely and wrap tightly before storing in a cool room. Alternatively, assemble and glaze the cake 1–2 days before serving and refrigerate it, covered, once the glaze has set.
Freezing: Wrap the cooled, unglazed cake or the filled but unglazed cake tightly in plastic wrap and then foil. Freeze for up to 2 months. Thaw overnight in the refrigerator, unwrap, and glaze before serving.
