Step 7: Cool the Cake Layers

Once baked, place the pans on wire racks and allow the cakes to cool for approximately 10 minutes.

Run a knife carefully around the edges to loosen the cakes.

Invert each cake onto a wire rack, remove the parchment or wax paper, and allow the layers to cool completely.

This step requires patience. Frosting a warm cake can cause the frosting to soften excessively and can make the layers difficult to handle.

Making the Chocolate Frosting

The frosting is what takes this cake from a simple chocolate cake to a truly decadent dessert.

Step 8: Heat the Cream Mixture

Place the heavy cream, butter, sugar, water, and salt into a medium heavy saucepan.

Heat over medium heat, stirring frequently, until the mixture reaches a gentle simmer.

You don’t need a vigorous boil. The goal is simply to heat the ingredients sufficiently to melt the chocolate in the next step.

Step 9: Add the Chocolate

Remove the saucepan from the heat.

Immediately add the remaining 1⅔ cups of dark chocolate morsels.

Let the chocolate sit in the hot cream mixture for about 2 minutes without disturbing it.

Then whisk until the chocolate melts completely and the frosting becomes smooth and glossy.

Add the remaining ½ teaspoon of vanilla extract and mix thoroughly.

Step 10: Let the Frosting Thicken

Pour the warm frosting into a medium bowl.

Place it in the refrigerator for approximately 1½ hours, stirring occasionally.

This is one of the most important parts of the recipe.

When the frosting first comes together, it will be too fluid to spread neatly. As it cools, the chocolate and butter firm up and transform it into a thick, spreadable frosting.

You’re looking for a texture that is:

• Smooth
• Glossy
• Thick enough to hold on a spatula
• Soft enough to spread easily

Don’t rush this stage.

Assembling the Cake

Step 11: Add the First Layer

Place one completely cooled cake layer on a serving plate or cake stand.

Spread an even layer of chocolate frosting over the top.

Try to take the frosting close to the edges without allowing it to spill over.

Step 12: Add the Second Layer

Carefully place the second cake layer on top of the frosted first layer.

If the layers have developed a small dome during baking, you can carefully level them with a serrated knife before assembling. This is optional but can make the finished cake more stable.

Step 13: Frost the Entire Cake

Use the remaining frosting to cover the top and sides of the cake.

An offset spatula makes this much easier.

You can leave the frosting with a deliberately rustic finish, or smooth the surface for a cleaner presentation.

Because the cake itself is already extremely chocolate-forward, elaborate decoration isn’t necessary.

Serving the Cake

Once the cake has been assembled, refrigerate it briefly to allow the frosting to set.

For the best texture, allow the cake to come closer to room temperature before serving. The frosting becomes softer and creamier as it warms, and the chocolate flavor becomes more pronounced.

Cut the cake with a sharp knife, wiping the blade between slices if you want particularly clean portions.

The finished cake should have a moist chocolate interior surrounded by rich, fudgy frosting.

Why This Cake Works So Well

The appeal of this recipe comes from the way several ingredients work together rather than relying on chocolate alone.

Chocolate Morsels

The dark chocolate morsels provide concentrated chocolate flavor in both the cake and frosting.

Strong Coffee

Coffee is a classic chocolate-baking ingredient because it can enhance the perception of chocolate without turning the dessert into a coffee-flavored cake.

Sour Cream

Sour cream contributes richness and moisture while helping create a tender crumb.

Vegetable Oil

Oil remains liquid at room temperature, helping the cake retain its soft texture.

Chocolate-Based Frosting

The frosting uses melted chocolate rather than relying solely on cocoa powder, producing a particularly rich and glossy finish.

Tips for the Best Result

Don’t overbake the layers. Start checking around the recommended baking time and look for a clean wooden pick or a few moist crumbs.

Cool completely before frosting. This prevents the frosting from melting and sliding off the cake.

Give the frosting enough time to thicken. If it is still runny, continue chilling it and stir periodically.

Use room-temperature sour cream and eggs. They incorporate more smoothly into the batter.

Measure carefully. Baking depends on specific proportions, particularly when working with flour and leavening ingredients.

Don’t skip the parchment. It makes removing the finished cake layers considerably easier.

Final Result

The finished Nestlé Toll House Death by Chocolate Cake is essentially a celebration of chocolate in every layer: a tender, dark cake, melted chocolate morsels, coffee-enhanced flavor, and a smooth chocolate frosting.

It is particularly well suited to birthdays, holiday gatherings, dinner parties, or any occasion when you want a dessert that feels more elaborate than an everyday chocolate cake.

The official Nestlé Toll House recipe describes the cake as a rich, moist, fudgy chocolate layer cake and recommends bringing refrigerated leftovers toward room temperature before serving.

In short: if you’re looking for a dessert where “more chocolate” is genuinely the answer, this cake earns its dramatic name.
