Essential Ingredients and Selection Tips
For the Cake:
- 2½ cups all-purpose flour - Use unbleached for the purest color.
- 1½ cups granulated sugar - Regular granulated works best.
- 1 tsp baking soda - Fresh is crucial for proper rise.
- 1 tsp salt - Fine sea salt for even distribution.
- 1 tsp cocoa powder - Natural, not Dutch-processed.
- 1½ cups vegetable oil - For ultimate moisture.
- 1 cup buttermilk (room temperature) - Real buttermilk, not a substitute.
- 2 large eggs (room temperature) - Essential for proper structure.
- 2 tbsp red food coloring - Gel-based for best results.
- 1 tsp purple food coloring - Adjust for desired vibrancy.
- 1 tsp white distilled vinegar - Activates the baking soda.

For the White Chocolate Cream Cheese Frosting:
- 1 lb cream cheese (softened) - Full-fat, room temperature.
- 1 cup unsalted butter (room temperature) - European-style preferred.

Step-by-Step Baking Instructions

- 1. Cake Batter Preparation
- Preheat your oven to exactly 350°F (175°C). Grease two 8-inch cake pans thoroughly and line the bottoms with parchment paper.
- In a large bowl, sift together flour, sugar, baking soda, salt, and cocoa powder—this isn't optional, as it ensures even distribution.
- In another bowl, whisk together oil, buttermilk, eggs, food colorings, vinegar, and vanilla until completely smooth.
- Gradually combine wet and dry ingredients, mixing just until combined—overmixing will affect texture.
- 2. Baking Process
- Divide batter evenly between prepared pans, using a scale for precision.
- Bake for 25-30 minutes or until a toothpick inserted into the center comes out clean.
- Let cakes cool in pans for exactly 10 minutes before turning onto a cooling rack.
- 3. Frosting Creation
- Melt white chocolate in 30-second microwave intervals, stirring between each.
- Beat cream cheese and butter together until completely smooth and fluffy—about 3-4 minutes.
- Gradually add sifted powdered sugar, ensuring no lumps remain.
- Pour in cooled white chocolate and vanilla, beating until perfectly smooth.
Cake Assembly and Decoration
Level cake layers if needed for even stacking. Place the first layer on a serving plate and spread with a generous amount of frosting. Top with the second layer and apply a thin crumb coat.
Chill for 15 minutes before applying the final coat of frosting. Decorate with fresh berries, edible glitter, or chocolate shavings.
Storage Instructions
- Refrigerate: Store in an airtight container for up to 5 days.
- Freeze: Wrap unfrosted cake layers tightly in plastic wrap and freeze for up to 3 months.
- Thaw: Let frozen layers thaw overnight in the refrigerator before frosting.
