Introduction

Ingredients
- ½ cup unsalted butter
- ¾ cup granulated sugar
- ¼ cup brown sugar
- ½ cup Dutch-process cocoa powder
- ¼ tsp salt
- 1 tsp vanilla extract
- 2 large eggs (room temperature)
- ½ cup all-purpose flour
- 1 tbsp cornstarch
- ¼ cup heavy cream
- 4 oz semisweet chocolate (chopped)
- Pinch of salt
- 2–3 tbsp rainbow candy-coated chocolate chips (Wilton rainbow chips or similar)
Instructions
- Step 1: Preheat your oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper.
- Step 2: In a medium saucepan, melt the butter over medium heat. Stir in the granulated sugar, brown sugar, cocoa powder, and ¼ tsp salt until the mixture is smooth and well combined.
- Step 3: Transfer this mixture to a large bowl and whisk in the vanilla extract.
- Step 4: Add the eggs one at a time, beating well after each addition until the batter becomes thick and shiny.
- Step 5: Gently fold in the flour and cornstarch just until combined; avoid overmixing.
- Step 6: Spread the batter evenly in the prepared pan and bake for 20–22 minutes, or until the edges are set and the center has a slight jiggle. Let the brownies cool completely.
- Step 7: Once cooled, flip the brownies out of the pan and remove the parchment paper. This will create a smooth flat surface for the ganache.
- Step 8: To make the ganache, heat the heavy cream in the microwave for 30 seconds. Pour it over the chopped semisweet chocolate and let sit for 1 minute.
- Step 9: Add a pinch of salt and stir the ganache until smooth and glossy, then spread it over the cooled brownies.
- Step 10: Immediately sprinkle the rainbow candy-coated chocolate chips on top while the ganache is still soft.
- Step 11: Chill the brownies in the refrigerator for 1–2 hours to set the ganache fully before slicing. For clean edges, wipe your knife between cuts.
Tips & Variations
- Use room temperature eggs to help the batter become thick and glossy for the best texture.
- For extra fudginess, underbake the brownies slightly; they continue to set as they cool.
- Swap rainbow candy chips with your favorite nuts or sprinkles if preferred.
- Try using dark chocolate instead of semisweet for a richer ganache flavor.
Storage
Store the brownies in an airtight container in the refrigerator for up to 5 days to keep the ganache firm and fresh. Before serving, allow them to sit at room temperature for about 15 minutes for optimal flavor and texture. You can also freeze the brownies for up to 2 months, thawing overnight in the fridge before enjoying.

FAQs
Can I use regular cocoa powder instead of Dutch-process?
Yes, you can substitute regular cocoa powder, but the flavor may be slightly less smooth and the color a bit lighter. Adjust baking soda or powder accordingly if your recipe calls for leavening.
How do I know when the brownies are done baking?
The edges should look set and slightly pulling away from the pan, while the center remains a little jiggly when you gently shake the pan. This ensures fudgy brownies that aren’t overbaked.

Ingredients
Brownie Base
- ½ cup unsalted butter
- ¾ cup granulated sugar
- ¼ cup brown sugar
- ½ cup Dutch-process cocoa powder
- ¼ tsp salt
- 1 tsp vanilla extract
- 2 large eggs (room temperature)
- ½ cup all-purpose flour
- 1 tbsp cornstarch
Chocolate Ganache
- ¼ cup heavy cream
- 4 oz semisweet chocolate (chopped)
- Pinch of salt
Topping
- 2–3 tbsp rainbow candy-coated chocolate chips (Wilton rainbow chips or similar)
Instructions
- Preheat Oven and Prepare Pan: Preheat your oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper to ensure easy removal and clean edges for the brownies.
- Melt Butter and Mix Sugars: In a medium saucepan on the stove, melt the unsalted butter over low heat. Once melted, stir in granulated sugar, brown sugar, Dutch-process cocoa powder, and salt until the mixture is smooth and well combined.
- Combine Wet Ingredients: Transfer the butter and sugar mixture to a large mixing bowl. Whisk in the vanilla extract, then add eggs one at a time, beating thoroughly after each addition until the batter thickens and becomes shiny.
- Incorporate Dry Ingredients: Gently fold in the all-purpose flour and cornstarch using a spatula until just combined, taking care not to overmix to maintain a tender texture.
- Bake the Brownies: Spread the batter evenly into the prepared pan. Bake for 20-22 minutes, or until the edges are set and the center jiggles slightly when shaken. Remove from oven and let cool completely in the pan.
- Prepare Brownie Surface: Once cooled, carefully flip the brownies out of the pan and peel away the parchment paper. This creates a flat surface on the bottom, ideal for applying the ganache and achieving a smooth finish.
- Make the Ganache: Heat the heavy cream in the microwave for about 30 seconds until very hot. Pour over the chopped semisweet chocolate and add a pinch of salt; let sit for 1 minute, then stir gently until the ganache is smooth and glossy.
- Spread Ganache on Brownies: Evenly spread the prepared ganache over the flat side of the cooled brownies.
- Add Rainbow Candy Chips: Immediately sprinkle the rainbow candy-coated chocolate chips over the soft ganache to decorate and add a delightful crunch.
- Chill and Serve: Place the brownies in the refrigerator and chill for 1-2 hours to set the ganache fully. Before slicing, wipe the knife clean between cuts for neat edges, and then serve and enjoy!
Notes
- Use room temperature eggs for better batter integration and texture.
- Do not overbake; the center should still have a slight jiggle for fudgy brownies.
- For a dairy-free version, substitute butter and heavy cream with plant-based alternatives.
- Chilling the ganache is essential to achieve a clean cut and a smooth chocolate layer.
- Store brownies in an airtight container in the refrigerator for up to 5 days.
- Feel free to customize the toppings with different candy chips or nuts if desired.
