Ingredients Needed
Gather these pantry staples for the cake and optional buttercream:
- All-purpose flour. Any standard brand will work.
- Granulated and light brown sugar. Light brown sugar should be lightly packed.
- Unsweetened cocoa powder. Regular or a darker variety if you prefer a deeper chocolate flavor.
- Baking powder and baking soda. Ensure they’re fresh for proper rise.
- Salt. A pinch to balance flavors.
- One large egg. Room temperature is best.
- Whole milk. You can substitute lower-fat or lactose-free milk if needed.
- Vegetable oil. Helps keep the cake moist.
- Peppermint extract. Use true peppermint extract rather than generic mint.
- Hot water. Warm but not boiling, used to bloom the cocoa and help create a tender crumb.
For garnish: crushed mini candy canes or candy cane hearts if you want a decorative accent.
Buttercream Frosting Alternatives
If Swiss meringue buttercream isn’t your preference, try one of these alternatives:
- Milk chocolate frosting for a creamier chocolate finish.
- Classic vanilla buttercream for a lighter, sweeter pairing.
- Ermine (flour) buttercream for a silky, less-sweet frosting.
- Chocolate buttercream for an extra-chocolate experience.
- Dark chocolate ganache for a glossy, rich topping—use a reduced batch to suit the small cake.
- Or keep it simple: dust with powdered sugar or a light cocoa dusting.

Recommended Baking Tools
A few helpful tools make this small cake easier to prepare:
- 6-inch cake pan. A 6 x 3-inch pan is ideal; a 6 x 2-inch pan will also work but the batter may reach the pan edge.
- Mixing bowls. One for dry and one for wet ingredients.
- Whisks and spatulas. For combining ingredients without overmixing.
- Parchment circle (optional). For easier cake removal from the pan.

Instructions
6 inch single layer peppermint chocolate cake
- Preheat oven to 350°F and position the rack just above center. Grease and flour a 6-inch cake pan, or use a parchment circle for easier removal.
- In a small bowl whisk together flour, granulated sugar, light brown sugar, cocoa powder, baking powder, baking soda, and salt.
- In a separate bowl whisk the egg, milk, vegetable oil, peppermint extract, and hot water until combined.
- Add the dry ingredients to the wet and whisk until just combined; avoid overmixing.
- Pour batter into the prepared pan and bake 25–28 minutes at 350°F, or until a toothpick inserted into the center comes out clean.
- Cool the cake in the pan for 10 minutes, then invert onto a wire rack to cool completely.
- Once cooled, dust with powdered sugar or frost with peppermint Swiss meringue buttercream and top with crushed candy canes.

- Place egg whites and granulated sugar in a heatproof bowl set over simmering water. Whisk constantly until the mixture reaches 150°F or the sugar dissolves and the mixture feels smooth between your fingers.
- Remove the bowl from the heat, dry the bottom, and whip on medium-high to high speed until stiff peaks form and the bowl feels cool to the touch (about 10–15 minutes).
- Add the butter one piece at a time, allowing each piece to incorporate fully. If the mixture looks curdled, continue beating until it smooths out.
- Switch to the paddle attachment, add the peppermint extract and salt, and beat 5–10 minutes until the buttercream is smooth and silky.
- Frost the cooled cake and serve.
