* In a separate bowl, whisk together flour, baking powder, and salt.
* Gradually add dry ingredients to wet ingredients, alternating with milk, beginning and ending with dry ingredients.
3. Divide and Flavor the Batters
* Divide the batter equally into three bowls.
* For the chocolate layer: Add cocoa powder and 2 tablespoons of milk to one portion, mixing until smooth.

* Leave the third portion as vanilla.
4. Bake the Layers
* Pour each batter into a prepared cake pan.
* Bake for 25-30 minutes or until a toothpick inserted comes out clean.

Troubleshooting & Pro Tips
- Layers not rising evenly? Make sure your baking powder is fresh and your oven temperature is accurate.
- Frosting too soft? Refrigerate for 15-20 minutes before continuing to frost.
- Colors not vibrant enough? Add more food coloring gradually or use gel food colors for more intense hues.
- Pro tip: Freeze cake layers for 30 minutes before frosting for easier handling and fewer crumbs.
- Smooth frosting trick: Dip your offset spatula in hot water, wipe dry, then smooth the frosting for a professional finish.
- Even layers: Use cake strips around your pans or lower the oven temperature to 325°F and bake longer for perfectly flat layers.
Storage & Make-Ahead Tips
- Make-ahead: Cake layers can be baked up to 2 days in advance. Wrap cooled layers tightly in plastic wrap and store at room temperature.
- Frosting: Can be made 1 day ahead and refrigerated. Let come to room temperature and re-whip before using.
- Assembled cake: Keeps well in the refrigerator for up to 3 days. Bring to room temperature for 1-2 hours before serving for best flavor and texture.
- Freezing: Unfrosted cake layers can be frozen for up to 1 month. The fully decorated cake can be frozen for up to 1 week.
