Step-by-Step Instructions

Step 1: Prepare the loaf pan and biscuits

Line a 25 x 11 cm (9 x 5 in) loaf pan with baking parchment. Let the parchment overhang on the long sides like a sling; this will make it easy to lift out the finished cake.

Open the packs of butter biscuits and count out roughly 300 g (about 60 biscuits). Set them beside the pan. You will be layering them in a neat single layer each time, so it helps to have them unwrapped and ready. If the biscuits are very large, you may need to break some in half to fit snugly along the edges.

Step 2: Gently heat the fats and cream

In a medium saucepan, combine the chopped coconut oil, unsalted butter, and heavy cream. Place the saucepan over low to medium-low heat.

Warm gently, stirring often, until the fat is completely melted and the cream is hot and steaming but not boiling. You should see small bubbles around the edges but no vigorous boiling. This usually takes 3–4 minutes. Remove the pan from the heat as soon as everything is melted and well combined.

Step 3: Make the silky chocolate-coconut glaze

Immediately add the finely chopped dark chocolate to the hot cream mixture. Let it sit without stirring for 1 minute to start melting.

After 1 minute, add the sifted powdered sugar, sifted cocoa powder, vanilla extract, and fine sea salt. Whisk slowly at first, then more vigorously, until the mixture is completely smooth, glossy, and lump-free. Take your time here; all cocoa and sugar should be fully dissolved and the texture should look like a thick, pourable ganache.

If a few small unmelted chocolate bits remain, place the pan back over the lowest heat for 15–30 seconds, whisking constantly, just until smooth. Do not let it boil.

Step 4: Cool to spreading consistency

Set the saucepan aside at room temperature for 10–15 minutes to cool slightly. Whisk once or twice as it cools. You want the mixture to thicken a little so it clings nicely to the biscuits, but still be easily pourable.

You are aiming for the consistency of warm, melted chocolate or a thick hot fudge sauce: it should coat a spoon but still flow off in a ribbon. If it is too runny, give it a few more minutes. If it becomes too thick, you can very gently rewarm it for a few seconds.

Step 5: Start layering biscuits and chocolate

Pour a thin layer of chocolate glaze (about 3–4 tablespoons) into the bottom of the lined loaf pan and spread it evenly with a spatula to cover the base.

Place a single layer of butter biscuits on top of the chocolate. Arrange them tightly, side by side, breaking a few pieces as needed to fit the corners and edges. Try to keep the layer flat and even.

Now pour another layer of chocolate glaze over the biscuits, using just enough to fully cover them in a thin, even layer. Gently tap the pan on the counter to help the chocolate settle and remove any air bubbles.

Step 6: Repeat layers and finish the top

Continue alternating layers of biscuits and chocolate glaze: a layer of biscuits, followed by a layer of chocolate, tapping the pan gently each time. Aim for at least 5–7 biscuit layers, depending on the thickness of your biscuits and loaf pan.

Finish with a final, slightly thicker layer of chocolate glaze on top, smoothing it with an offset spatula or the back of a spoon. If you like, sprinkle biscuit crumbs, chocolate shavings, and a tiny pinch of flaky sea salt over the surface for texture and looks.

Use up all the glaze; if you have a little leftover, pour it into the center and spread outward so the top is nice and level.

Step 7: Chill, unmold, and slice

Cover the pan loosely with foil or plastic wrap (avoid touching the surface of the chocolate) and place it in the refrigerator for at least 4 hours, or ideally overnight. The longer chill allows the coconut fat and chocolate to fully set, giving you clean slices.

When ready to serve, lift the Kalter Hund out of the pan using the parchment sling and place it on a cutting board. Peel the parchment away from the sides.

For neat slices, heat a sharp knife under hot water, wipe it dry, and then cut the loaf into 12 slices, about 1.5–2 cm (1/2–3/4 in) thick. Wipe and rewarm the knife as needed between cuts. Serve cold or just slightly cool, optionally with fresh berries and a dollop of whipped cream.

Pro Tips

• Use good-quality chocolate: A 60–70% dark chocolate gives a deep, not-too-sweet flavor that balances the plain biscuits beautifully.
• Keep the heat gentle: Boiling the cream or overheating the fats can cause the chocolate to split. Warm just until hot and then remove from the heat before adding chocolate.
• Neat layers = pretty slices: Take a moment to arrange biscuits in straight rows, pressing them lightly into each chocolate layer. This gives you sharp, checkerboard-style slices.
• Chill fully before slicing: If the loaf is even slightly soft, it will squish when cut. For best definition, chill overnight and use a warmed, dry knife.
• Adjust sweetness to taste: If you prefer it less sweet, reduce powdered sugar to 90 g (3/4 cup) and use a slightly sweeter chocolate (around 55–60%).

Variations

• Nutty Kalter Hund: Sprinkle 2–3 tablespoons of finely chopped roasted hazelnuts or almonds over every second chocolate layer for extra crunch and a nutty aroma.
• Orange-chocolate twist: Add 1–2 tsp finely grated orange zest to the chocolate glaze and, if you like, a tablespoon of orange liqueur (such as Cointreau) for a more grown-up flavor.
• Mocha version: Dissolve 1–2 tsp instant espresso powder in the hot cream before adding the chocolate to give the loaf a subtle coffee note that pairs beautifully with the biscuits.

Storage & Make-Ahead

Store Kalter Hund tightly wrapped or in an airtight container in the refrigerator for up to 5–6 days. Because it is rich in chocolate and coconut fat, it stays firm and sliceable when chilled. For the best flavor and texture, let slices sit at room temperature for about 5–10 minutes before serving so the chocolate softens slightly.

For longer storage, you can freeze the loaf whole or in slices. Wrap it well in plastic wrap and then foil, or place slices in an airtight container with parchment between layers. Freeze for up to 2 months. Thaw overnight in the refrigerator, then slice and serve.

This dessert is ideal for making ahead. Prepare it 1–2 days before you need it; the flavor actually improves as it rests and the biscuits soften slightly into the chocolate.
