Tools and Equipment
These are the primary tools you will need to make this cake:
- Stand or hand mixer
- Large mixing bowl
- Rubber spatula
- Three, 6-inch cake pans
- Offset spatula
- Cake board or parchment paper
- Rimmed baking sheet
Before you roll the cake, place a piece of parchment paper on top of the cake to give yourself something to hold on to. Remove the parchment before sprinkling the sparkly sugar on top.
First, fill cooled and trimmed layers with buttercream then ice the cake.
Next, roll the sides of the cake in sparkly sugar on a rimmed baking sheet.
Continue to roll until the sides are covered. Use your hands to help the sugar stick as needed.
Invert the cake. In the same fashion, sprinkle sugar on top of the cake. Press to stick.
Lastly, place sprigs of rosemary on top of the cake to make a snowy rosemary forest.
Hint: chill the cake so that it does not smush under its own weight when being rolled but before the buttercream crusts over too much or else the sugar will not stick as easily.
Chocolate Peppermint Cake Tasting Notes
Today, I will be sharing the recipe straight from the book in partnership with Rodelle. I’ve been using their products for years, including the time I spent recipe testing for the book.
Their premium cocoa powders are so lush and rich. I can truly taste the difference in my chocolate cake recipes!
Real vanilla bean is a game changer, and their beans and extracts bring my baking to a new level - especially in this buttercream. A splash of peppermint extract gives the cake a fresh, festive feel.
Sour Cream - You can swap out the sour cream and milk for equal parts buttermilk. The taste and texture will be comparable. If you opt for a buttermilk substitute (ie milk + vinegar), the end results will likely be slightly off.
Coffee - You can use instant coffee dissolved in hot water. If you prefer, skip the coffee all together and just use plain hot water.
No, unfortunately you can’t use natural cocoa powder instead of Dutch-processed. One is acidic while the other is neutral. You could try in a pinch, but understand that it will change the results.
Yes! You can use this recipe to make two 8 or 9-inch cakes. Adjust the baking time accordingly. Make sure to only fill the pans ⅔ of the way full.
Choose a good quality aluminum cake pan with at least 2-inch tall sides.
Yes! Wait until the cakes have completely cooled before wrapping well in plastic. If desired, wrap in a layer of foil or pop the cakes into a zip-top freezer bag. Freeze for up to 3 months. Thaw in the refrigerator overnight.
Serving and Storage
Serve the cake at room temperature. Store the cake at a moderate room temperature overnight (preferably in a cake box or under a glass cake dome).
Wrap leftovers loosely in plastic and store in the refrigerator for up to 4 days.
Freeze unfrosted layers wrapped well in plastic for up to 3 months.
