Method
Make the cake
- Heat the oven to 350°F.
- Grease an 8-inch square metal baking pan.
- Whisk the flour, brown sugar, cocoa powder, baking powder, baking soda, and salt in a medium bowl.
- In a separate bowl, whisk the egg, buttermilk, oil, and vanilla.
- Stir the wet ingredients into the dry ingredients.
- Whisk in the hot water until the batter is smooth.
- Pour the batter into the pan and bake for 28 to 34 minutes, until a toothpick inserted in the center comes out with a few moist crumbs.
- Cool completely in the pan, about 1 hour.
- Cut the cake into 1-inch cubes.
Cook the pudding
- In a 2-quart saucepan, whisk the sugar, cornstarch, and egg yolks until smooth.
- Gradually whisk in the milk.
- Cook over medium heat, whisking constantly, until the pudding boils and thickens.
- Continue cooking for 1 minute.
- Remove from the heat and stir in the chocolate until melted.
- Transfer the pudding to a bowl and press plastic wrap directly onto its surface.
- Refrigerate until cold, at least 2 hours.
Make the peppermint whipped cream and assemble
- Beat the heavy cream and powdered sugar in a chilled bowl until soft peaks form.
- Add the peppermint extract and beat until medium-stiff peaks form.
- In a 4-quart trifle bowl, layer half the cake cubes, half the pudding, and half the whipped cream.
- Sprinkle with 1/4 cup of the crushed peppermint candies.
- Repeat with the remaining cake, pudding, and whipped cream, then top with the remaining candies.
- Cover and refrigerate for at least 2 hours before serving.
Notes
For distinct layers, let the pudding chill until completely cold before assembling. Refrigerate covered for up to 3 days; freezing is not recommended because the whipped cream and pudding can change texture. For a gluten-free version, use a 1:1 gluten-free baking flour in place of the all-purpose flour.
