Equipment

9x13 inch baking pan
Mixing bowls
whisk
spatula
saucepan

Ingredients

1 cup unsalted butter
2 cups granulated sugar
4 large eggs
2 tsp vanilla extract
1 cup all-purpose flour
3/4 cup unsweetened cocoa powder
1/2 tsp salt
1/2 tsp espresso powder (optional)
1/4 tsp baking powder
1 1/2 cups semi-sweet chocolate chips
1/2 cup heavy cream
1 tbsp corn syrup
1/4 cup rainbow chips or mini M&Ms

Instructions

Preheat oven to 350°F (175°C) and line a 9x13-inch baking pan with parchment paper.
Melt butter in a large bowl, then whisk in sugar until combined.
Add eggs one at a time, whisking well after each addition, then stir in vanilla extract.
In a separate bowl, whisk together flour, cocoa powder, salt, espresso powder, and baking powder.
Gradually fold dry ingredients into wet mixture until just combined.
Pour batter into prepared pan and spread evenly.
Bake for 25–30 minutes until a toothpick inserted comes out with moist crumbs.
Allow brownies to cool completely in the pan.
Place chocolate chips in a bowl. Heat cream until just simmering, then pour over chocolate and let sit.
Whisk until smooth, then stir in corn syrup.
Pour ganache over cooled brownies and spread evenly.
Sprinkle rainbow chips on top while ganache is still soft.
Refrigerate for 30 minutes until ganache is set, then slice and serve.

Notes

Do not overbake to maintain fudgy texture. Allow brownies to cool completely before adding ganache. Use high-quality chocolate for best flavor. Store in an airtight container for up to 5 days or refrigerate for longer freshness.
