FAQ

1. Can I make the cake layers ahead of time?

Yes. Bake the layers up to 2 days in advance, wrap tightly, and store at room temperature or freeze up to 1 month.

2. Can I use frozen blackberries?

Yes. Thaw and drain before using in the reduction to avoid excess water.

3. Does the filling hold up well?

It holds beautifully after chilling. You can stabilize it further by adding ½ tsp gelatin (bloomed and melted) if making in advance.

4. Can I make cupcakes instead?

Absolutely. Fill cupcake liners ¾ full and bake at 350°F for 18–20 minutes. Core and fill with blackberry cream for a surprise center.

5. How do I get a deeper black color in the cake?

Use black cocoa (not regular cocoa) and a few drops of black gel food coloring if needed.

6. What’s the difference between this and red velvet?

Black velvet uses black cocoa instead of regular cocoa and food coloring. It’s richer, less sweet, and more intense.

7. How long does it last?

Store in the fridge for up to 4 days. Let slices come to room temp before serving for best texture.
