👩🍳 Instructions
1. Prepare the brownies
Preheat oven to 350°F (175°C) and line an 8×8-inch pan with parchment paper.
Melt butter in a saucepan, then stir in granulated sugar, brown sugar, cocoa powder, and salt until smooth.
Transfer mixture to a bowl, add vanilla, then whisk in eggs one at a time until thick and glossy.
Fold in flour and cornstarch just until combined.
2. Bake
Spread batter evenly in the pan.
Bake for 20–22 minutes until edges are set and center is slightly soft.
Let brownies cool completely.
3. Make the ganache
Heat cream until hot (not boiling), then pour over chopped chocolate.
Let sit 1 minute, add salt, and stir until smooth and glossy.
4. Assemble
Spread ganache evenly over cooled brownies.
While still soft, sprinkle rainbow chips on top.
Refrigerate for 1–2 hours until set.
5. Slice & serve
Use a sharp knife and wipe between cuts for clean, perfect squares.
