Preparation:

Step 1: Prepare the Batter

1. Preheat your oven to 350°F (175°C) and grease a Bundt pan thoroughly.
2. In a medium bowl, whisk together the flour, cocoa powder, baking soda, and salt.
3. In another bowl, combine buttermilk, vinegar, and vanilla extract.

Step 2: Mix Wet Ingredients

1. In a large mixing bowl, beat the sugar and vegetable oil until well combined.
2. Add the eggs one at a time, mixing after each addition.
3. Gradually add the red food coloring until the desired vibrant hue is achieved.

Step 3: Combine Wet and Dry Ingredients

1. Alternate adding the flour mixture and buttermilk mixture to the wet ingredients, beginning and ending with the flour.
2. Mix until just combined, avoiding overmixing to ensure a light texture.

Step 4: Bake the Cake

1. Pour the batter into the prepared Bundt pan and smooth the top.
2. Bake for 40–45 minutes or until a toothpick inserted into the center comes out clean.
3. Let the cake cool in the pan for 10 minutes, then invert it onto a wire rack to cool completely.

Step 5: Prepare the Frosting

1. Beat the softened butter and cream cheese together until smooth and creamy.
2. Gradually add powdered sugar, one cup at a time, mixing well after each addition.
3. Stir in the vanilla extract and beat until fluffy.

Step 6: Decorate the Cake

1. Pipe the frosting onto the cooled cake using a star or rose tip to mimic the look of a wreath.
2. Garnish with fresh cranberries and rosemary sprigs to enhance the festive appearance.
3. Dust lightly with powdered sugar to resemble snow.
