✅ Before You Start

What You'll Need (Beginner Kit):

Offset spatula or butter knife
Rotating cake turntable (optional but game-changing)
Piping bag + star tip
Parchment paper
Bench scraper

You've been there. You bake a perfectly good chocolate cake, then stare at it wondering: How do I make this look like it came from a real bakery?

Here's the truth: you don't need a cake degree. You just need the right ideas — and a few clever shortcuts.
