Cake Instructions

Step 1

• Preheat the oven to 350°F (175°C). Do not use the convection (fan) setting.

Step 2

• Grease a large, rectangular baking dish (Baker’s Joy is indispensable in my kitchen) and set aside.

Step 3

• Whisk the dry ingredients together (cake flour, cocoa powder, sugar, baking powder baking soda, and salt) and set aside.

Step 4

• In the bowl of a stand mixer (or in a large mixing bowl), add the buttermilk, hot water, espresso powder, vegetable oil, and sour cream, and mix to combine, using the paddle attachment of your stand mixer (or using an electric hand mixer). Add the eggs, and mix again to combine. Add the dry ingredients, and mix until well-combined.

Step 5

• Add the batter to the greased baking dish, and bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. Allow to cool in pans for up to 45 minutes, then cool fully on a cooling rack.
  

Step 6

• While the cake is cooling, prepare the cherry filling and stabilized whipped cream.

Cherry Filling

Step 1

• Add the cherry filling ingredients to a large saucepan, and stir well to combine. Allow to sit on the counter for 15 minutes.

  Heat over medium-low heat for 5-7 minutes or until slightly thickened. You don’t want it too thick (like cherry pie filling) as the cake should absorb the cherry syrup. If it becomes too thick, you can add more water and/or Kirschwasser; if it is too thin, add a little more tapioca flour.
  

Step 2

• Set aside to cool to room temperature, then allow to chill in the refrigerator until ready to use.

Stabilized Whipped Cream

Step 1

• In a small, heavy saucepan (such as a Dutch oven), whisk together the sugar and cornstarch until combined. Add 1 cup (235mL) cream, and whisk to combine.

Step 2

• Warm saucepan over medium-low heat, watching carefully to ensure it does not burn, and bring to a simmer. Simmer the mixture for 2 minutes, and set in the refrigerator to chill.

Step 3

• For best results, transfer a mixing bowl and whisk attachment to refrigerator or freezer to chill before mixing the whipped cream. When you are ready to make it, transfer 3 cups (710 mL) heavy cream to a stand mixer, and mix on medium speed for 3-5 minutes, until it begins to thicken and increase in volume.
  

Step 4

• Add the thickened cream-cornstarch mixture, and continue to beat for 2-3 minutes or until soft peaks have formed. Do not overbeat. Transfer to a covered dish, and chill. The whipped cream will keep without deflating for up to 4 days in the refrigerator.
  

Assembly

Step 1

• As soon as the cake is cool, and the whipped cream and cherries are cold, you can make the trifle. To make an attractive trifle, decide how many layers yours will be (for the size of my trifle dish, I usually do 3-4 layers) and either measure or try to divide ingredients evenly between each layer.

Step 2

• Break the cake up into large chunks. Line the bottom of the trifle dish with one-third (for example) of the cake, and spoon over one-third of the cherry filling, followed by one-third of the whipped cream.

Step 3

• Continue to build the trifle layer by layer, ending with a layer of whipped cream and garnishing with decorations of your choice. Chocolate curls and stemmed cherries are traditional; I often add extra cake pieces to the food processor and crumble the cake on top. Refrigerate until ready to serve; the trifle tastes best when it sits for a few hours before serving to allow the sponge cake to absorb the cherry syrup.
