Black-and-White Malted Icebox Cake
Malt is one of those nostalgic flavors that evokes childhood. Anything “malted” to us has that comfort food aspect. Jean Sagendorph and Jessie Sheehan bring us this recipe as well as the Red Velvet Icebox Cake from their book, Icebox Cakes. In this cake they begin with a homemade vanilla wafer with a nice hefty dose of vanilla for great flavor. Layered with a milk chocolate ganache and malted whipped cream and – well just look at the image! This is a fabulous warm weather dessert. Do ahead – it needs a 24 hour rest in the fridge – and pull out for a backyard party or summer birthday.

Jessie’s love of Whoppers (and extra-thick malted milkshakes) inspired this cake. Malt alone gives vanilla a creamy, slightly nutty dimension, and is also the perfect foil to the sweetness of milk chocolate.
One 9-by-3-in/23-by-7.5-cm springform pan
- 2 cups/270 g all-purpose flour
- 1∕2 tsp salt
- 1 1∕4 cups/250 g granulated sugar
- 3∕4 cup/170 g unsalted butter, at room temperature
- 1 Tbsp pure vanilla extract
- 2 Tbsp whole milk
- 1 Tbsp light corn syrup
- 13 oz/370 g milk chocolate, finely chopped
- 1∕4 tsp salt
- 3∕4 cup/180 ml heavy cream
- 1 qt/960 ml heavy cream
- 1∕2 cup/170 g malted milk powder
- 1∕2 cup/65 g confectioners’ sugar
- 2 tsp pure vanilla extract
- Crushed or chopped malted milk balls for decorating
- MAKE WAFERS: In a medium bowl, whisk together the flour and salt.
- In the bowl of a stand mixer fitted with the paddle attachment, cream the granulated sugar, butter, and vanilla on medium-low speed until slightly fluffy, about 2 minutes. Be careful not to overbeat. Scrape the sides of the bowl with a rubber spatula.
- In a small bowl, whisk the milk and corn syrup to combine. Add the milk mixture to the butter-sugar mixture with the mixer on medium-low speed; beat until just combined. Scrape the sides of the bowl with the rubber spatula.
- Add the flour mixture all at once to the mixer bowl. With the mixer on low speed, beat until the dough just begins to pull away from the bottom of the bowl and forms a cohesive mass. Scrape the sides of the bowl to fully incorporate all the ingredients.
- Divide the dough in half and place each half on a sheet of plastic wrap. Loosely wrap the dough and form each half into a log about 2 in/5 cm wide. Roll the logs along the counter, still wrapped in plastic wrap, in order to shape into perfect cylinders. Tighten the plastic wrap around the logs and freeze them for at least 2 hours, or overnight. If you have trouble forming the soft dough into logs, form the dough into a disk (or loose log shape), wrap it in plastic wrap, and place in the freezer for about 20 minutes, just until it is cold enough to shape into the necessary log. Line two baking sheets with parchment paper.
- Once frozen, unwrap one of the logs and use a sharp paring or chef’s knife to cut it into thin slices about 1∕8 in/3 mm thick; rotate the log as you slice, or the side sitting on the cutting surface will flatten. Arrange the slices about 1 in/2.5 cm apart on one of the prepared baking sheets and place in the freezer for at least 10 minutes. Repeat with the second dough log and prepared baking sheet. If you need more room to fit all your dough slices, simply arrange them on additional sheets of parchment paper, layer the dough-covered papers one on top of the other on the second baking sheet in the freezer, and switch them out as you bake off each batch. (You can also wrap the baking sheets in plastic wrap and freeze the rounds for up to 1 week.)
- Position a rack in the center of the oven and preheat to 350˚F/180˚C. Place one baking sheet of the frozen dough rounds in the oven and bake until they begin to brown just around the edges, 10 to 12 minutes, rotating the sheet halfway through the baking time. Using a stiff metal or plastic spatula, immediately press down lightly on each cookie to flatten it. Let the wafers cool on the baking sheet for 2 to 3 minutes, then transfer them to a wire rack to cool completely. The wafers should be very crispy when cooled. If they are not, place them back in the 350˚F/180˚C oven for 1 to 2 minutes more. Repeat to bake the additional sheets of frozen dough rounds.
- Store the wafers in an airtight container as soon as they have cooled. They will remain crispy at room temperature, tightly sealed, for about 24 hours. Freezing the baked wafers in a resealable plastic bag also works well, for up to 1 month. There is no need to defrost the wafers before assembling your cake.
- MAKE GANACHE: Place the chocolate and salt in a medium heatproof bowl and set aside. In a small saucepan, heat the cream over medium-high heat just until bubbles begin to form around the edges.
- Pour the warm cream over the chocolate and salt and let sit for 1 minute so it begins to melt. Gently whisk together until fully incorporated and shiny.
- Let come to room temperature, stirring occasionally, until it thickens and is less like chocolate syrup and pours more like hot fudge. (To make ahead, let cool to room temperature, cover, and refrigerate for up to 1 week. Reheat over medium-low heat until liquefied.)
- MAKE WHIPPED CREAM: Refrigerate the bowl of a stand mixer and the whisk attachment (or a medium metal bowl and beaters from a hand mixer) until quite cold, about 15 minutes.
- Once chilled, remove the bowl and whisk from the refrigerator, add the cream, and whip it on medium speed until just thickened.
- Add the malted milk powder, confectioners’ sugar, and vanilla and, on medium-high speed, whip the cream until it holds stiff peaks that stand upright when the whisk is raised (the stiffer the cream, the more support it will provide the wafers in your cake). Use it immediately.
- Lightly coat the sides of your springform pan with cooking spray and line the sides of the pan with a 3-by-29-in/7.5-by-75-cm strip of parchment paper. Using a small offset spatula or the back of a spoon, spread a generous layer of the whipped cream on the bottom of the pan.
- Cover as much of the whipped cream as possible with a layer of the wafers, filling any gaps with broken wafers. The pieces should touch. The goal is a solid layer of wafers.
- Generously spread a layer of the ganache over the wafers. Continue layering in this order (whipped cream, wafers, ganache) until you run out or reach the top of the pan. Spread the top of the cake with a final layer of whipped cream and gently cover it with plastic wrap. Refrigerate for 24 hours.
- Peel the plastic wrap from the cake and run a paring knife between the paper and the pan. Open the clamp, remove the pan sides, and gently peel back the parchment paper. Transfer the cake, still on the pan bottom, to a serving platter. Sprinkle crushed malted milk balls on top of the cake. Using a knife, slice into wedges and serve.
