Dry Ingredients
- 170 grams (1 1/4 cups + 2 Tablespoons) All-Purpose Flour (e.g. Gold Medal)
- 1 1/2 teaspoons Baking Powder
- 1 teaspoon Baking Soda
- 3/4 teaspoon Salt
- 3 Tablespoons Chocolate Instant Pudding Mix or 2 Tablespoons instant clearjel
- 26 grams (1/4 cup) Unsweetened Cocoa Powder (e.g. Hershey’s)
- 100 grams (1/2 cup) Sugar
- 113 grams (1/2 cup packed) Brown Sugar
Wet Ingredients
- 2 large Eggs
- 3/4 cup Buttermilk
- 1/4 cup brewed Coffee
- 1/4 cup + 1 Tablespoon Vegetable Oil
- 3 Tablespoons Dark Corn Syrup (or light corn syrup)
- 1 1/2 teaspoons Vanilla Extract
Chocolate Butter Mixture
- 3/4 stick (3 ounces) Salted Butter
- 43 grams (1/4 cup) Semi-Sweet Chocolate Chips (e.g. Nestle)
Peppermint Ganache Filling
- 1/2 cup Heavy Cream
- 172 grams (1 cup) Semi-Sweet Chocolate Chips (e.g. Nestle)
- 3/4 teaspoon Pure Peppermint Extract (e.g. Olive Nation)
Peppermint Buttercream Frosting
- 455 grams (3 1/2 cups) Powdered Sugar
- 1 Tablespoon Instant Clearjel (optional, food starch)
- 4 ounces Cream Cheese
- 1 1/2 sticks (6 ounces) Salted Butter, room temperature
- 48 grams (1/4 cup) Shortening
- 1 Tablespoon Pure Vanilla Extract
- 3/4 teaspoon Pure Peppermint Extract (e.g. Olive Nation)
- Make Chocolate Cake: Preheat your oven to 325°F. Line a 1″ tall 1/4 sheet pan with parchment paper and spray the bottom and sides with cooking spray to prevent sticking.
- Mix Dry Ingredients: Sift the flour, baking powder, baking soda, salt, instant pudding mix or clearjel, cocoa powder, and granulated sugar into a large bowl. Add brown sugar and whisk thoroughly, breaking up any clumps to ensure a smooth mixture.
- Mix Wet Ingredients: In a separate large bowl, whisk together eggs, buttermilk, brewed coffee, vegetable oil, dark corn syrup, and vanilla extract until well combined.
- Make Butter Mixture: Melt the salted butter either in the microwave or on the stove until just melted. Add the semi-sweet chocolate chips and whisk vigorously for 30 seconds to 1 minute until the mixture is melted and smooth.
- Combine Ingredients: Pour the wet ingredients into the dry ingredients and whisk until incorporated. Then pour in the chocolate butter mixture and whisk until smooth and lump-free, allowing some small brown sugar lumps to remain.
- Spread Batter into Pan: Pour the batter into the prepared sheet pan and smooth it out evenly using an offset spatula. The batter should come close to the top edge but leave space.
- Set Batter: Let the batter rest in the pan for 5-10 minutes so the instant clearjel or pudding mix can thicken for better rise during baking.
- Bake Cake: Place the pan in the middle or top rack of the oven. Bake for 16 minutes at 325°F. Without opening the oven, reduce heat to 300°F and bake for an additional 6-10 minutes. Check doneness by lightly touching the cake’s surface and inserting a toothpick; it should come out clean or with moist crumbs but not wet. Extend baking 1-5 minutes if needed.
- Wrap and Freeze Cake: Once cooled, tightly wrap the cake in plastic wrap while still in the pan and freeze for at least 2 hours or overnight. For longer storage, brush with simple syrup before wrapping. Cake will be easier to layer frozen.
- Make Peppermint Ganache: Heat heavy cream and semi-sweet chocolate chips in a microwave-safe bowl in 30-second increments, stirring between each until smooth and shiny. Whisk in peppermint extract once melted.
- Chill Ganache: Refrigerate the ganache, stirring occasionally, until it thickens to a very fudgy consistency. Reheat briefly if it becomes too firm before use.
- Prepare Peppermint Buttercream: Whisk together powdered sugar and instant clearjel. Beat cream cheese until softened, add room temperature butter and shortening, and continue to beat until creamy and lump-free.
- Add Sugar Mixture and Extracts: Slowly add the powdered sugar mixture to the creamed butter mix on low speed. Add vanilla and peppermint extracts, scraping the bowl as needed.
- Beat Buttercream: Increase mixer speed to high and beat for 2-3 minutes to make the buttercream light and fluffy; it will thicken further as it rests.
- Layer Cake: Use cake rings to cut frozen cake layers. Spread ganache about 1/4 inch thick between layers. Apply a thin crumb coat of peppermint buttercream on the outside and chill until firm.
- Decorate and Serve: Frost cake with a final thick layer of peppermint buttercream. Warm reserved ganache to drizzle down sides. Optionally pipe rosettes with a star tip around the top. Allow cake to come to room temperature before serving and decorate with mini candy canes. Enjoy the cake best at room temperature.
Notes
- Instant Clearjel is a food starch used commercially to improve cake texture and stability; it can be substituted with instant pudding mix.
- Using parchment paper and spray ensures easy removal of thin cake layers from the pan, essential for layering delicate cakes.
- Brushing the cake with simple syrup before freezing protects moisture and enhances flavor if storing longer than a couple of days.
- Be careful not to overheat butter or chocolate when melting to avoid scorching and grainy texture.
- When working with ganache, frequent stirring and microwaving in short bursts helps prevent overheating.
- Layering the cake when frozen yields cleaner cuts and easier assembly.
