Instructions

1. Preheat oven to 350°F (175°C) and line two baking sheets with parchment paper.

2. In a large bowl, whisk together melted butter, granulated sugar, and brown sugar until smooth.

3. Add eggs and vanilla; mix until fully combined.

4. Sift in cocoa powder, flour, baking soda, and salt. Mix until a thick dough forms.

5. Scoop 2 tbsp-sized balls and place on baking sheets, spaced apart. Flatten slightly.

6. Bake for 9–11 minutes. The edges should be set but centers slightly soft. Cool completely.

8. For ganache, heat cream until just simmering and pour over chocolate chips. Let sit 1–2 minutes, then stir until smooth.

9. Spread ganache over each cooled cookie and top with rainbow chips.

10. Let set slightly before serving or store in an airtight container.

Notes

• Chill dough 30 minutes for thicker cookies.

• Use Dutch-processed cocoa for a richer flavor.

• These freeze beautifully—ganache after thawing if needed.
