Ingredients
- 1 cup unsalted butter
- 4 oz semi-sweet chocolate, cut into pieces (or chocolate chips)
- 1 cup granulated sugar
- 1/2 cup brown sugar
- 2 tsp vanilla extract
- 3 eggs
- 2/3 cup unsweetened cocoa powder
- 3/4 cup all purpose flour
- 2 Tbsp cornstarch
- 1/2 tsp salt
- 1 cup semi-sweet chocolate chips
- 1/2 cup heavy whipping cream
- Colored chocolate candies, mini M&Ms, or sprinkles for topping
Instructions
- Step 1: Preheat your oven to 350°F (175°C) and line a 9×13-inch pan with parchment paper or grease it well. Set aside.
- Step 2: In a large bowl, melt the butter and 4 oz chocolate together in the microwave using 30-second increments. Stir after each interval until completely melted and smooth.
- Step 3: Whisk in the granulated sugar, brown sugar, and vanilla extract until well combined.
- Step 4: Add the eggs one at a time, whisking well after each addition to incorporate thoroughly.
- Step 5: Sift in the cocoa powder, all-purpose flour, cornstarch, and salt. Whisk everything until fully combined and smooth.
- Step 6: Pour the brownie batter evenly into the prepared pan and smooth the top with a spatula.
- Step 7: Bake for about 20 minutes or until the surface is set and a cake tester inserted comes out with a few moist crumbs. Let the brownies cool for about 20 minutes before adding the ganache.
- Step 8: To make the ganache, heat the heavy whipping cream until just below boiling, either on the stove or in the microwave.
- Step 9: Place the 1 cup chocolate chips in a small bowl and pour the hot cream over them. Cover with a towel and let sit for 5–7 minutes to soften the chocolate.
- Step 10: Whisk the cream and chocolate until smooth and glossy.
- Step 11: Pour the ganache over the cooled brownies and spread it evenly. Top with colored chocolate candies, mini M&Ms, or sprinkles as desired.
- Step 12: Chill the brownies in the refrigerator for at least 60 minutes to set the ganache before cutting and serving. Cut into 15 to 20 pieces depending on the size you prefer.
Tips & Variations
- Use a sharp knife dipped in hot water, wiped dry, to cut clean slices without cracking the ganache.
- Swap semi-sweet chocolate with dark or milk chocolate to adjust sweetness levels.
- Try adding chopped nuts or swirl peanut butter into the batter for extra texture and flavor.
- For a thicker ganache layer, increase heavy cream to 2/3 cup.
Storage
Store leftover brownies in an airtight container in the refrigerator due to the cream in the ganache. They will keep well for up to 5 days. To serve, let the brownies sit at room temperature for about 15 minutes or warm gently before enjoying.

FAQs
Can I make these brownies gluten-free?
Yes, substitute the all-purpose flour with a gluten-free flour blend that includes xanthan gum for best results. The texture may vary slightly but will still be delicious.
Can I prepare the ganache ahead of time?
Absolutely. You can make the ganache a day in advance and refrigerate it. Before spreading, warm it slightly to make it pourable and smooth.

Instructions
- Preheat oven and prepare pan: Preheat your oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper or grease it thoroughly to prevent sticking. Set aside.
- Melt butter and chocolate: In a large bowl, melt the butter and semi-sweet chocolate together using the microwave. Heat in 30-second increments, stirring after each interval, until fully melted and smooth.
- Add sugars and vanilla: Whisk the granulated sugar, brown sugar, and vanilla extract into the melted chocolate mixture until well combined.
- Incorporate eggs: Add the eggs one at a time to the mixture, whisking well after each addition to make a smooth, glossy batter.
- Add dry ingredients: Sift in the cocoa powder, all-purpose flour, cornstarch, and salt. Whisk until the batter is completely combined and smooth without streaks of flour.
- Spread batter in pan: Pour the brownie batter into the prepared baking pan and spread evenly with a spatula to ensure uniform thickness.
- Bake brownies: Bake in the preheated oven for about 20 minutes, or until the top is set and a toothpick inserted comes out with a few moist crumbs. Avoid overbaking for fudgy brownies. Remove from oven and let cool in the pan for about 20 minutes.
- Prepare ganache: Heat the heavy whipping cream until it is just below boiling, either on the stove or in the microwave. Place the semi-sweet chocolate chips in a small bowl and pour the hot cream over them. Cover with a towel and let sit for 5-7 minutes to soften and melt the chocolate.

- Chill brownies: Refrigerate the brownies for at least 60 minutes to allow the ganache to set properly before cutting.
- Serve: Cut into 15-20 squares based on preferred size. Store any leftovers refrigerated due to the creamy ganache topping.
Notes
- Use parchment paper for easy removal and clean edges when lifting brownies out of the pan.
- Do not overbake brownies; they should be fudgy and moist inside with just set tops.
- Allow ganache to cool slightly before pouring to avoid melting the brownies too much.
- Store leftovers in an airtight container in the refrigerator and consume within 4-5 days for best freshness.
- Customize the toppings with any favorite candies or nuts for variation.
