Get ready to make some brownies! Start by preheating your oven to 350°F (175°C). Take an 8 by 8-inch metal baking pan and line it with parchment or foil. Then lightly coat it with cooking spray.

Now let’s prepare the brownie batter. In a bowl that’s safe for use in the microwave melt the butter for approximately 90 seconds on high power. Next add in the granulated sugar, brown sugar and sifted cocoa powder. If it’s still too hot allow it to cool slightly before adding the vanilla extract, eggs, egg yolk and corn syrup. Stir everything together until well combined. After that incorporate the all-purpose flour, cornstarch and salt into the mixture; stir until combined. The batter will be thick but chocolatey! Pour this concoction into your pan.

It’s time to bake these brownies to perfection! Place your brownie masterpiece into the oven. Let it bake for around 25 minutes. You’ll know they’re done when the edges are set. The center is still gooey. Once baked thoroughly remove them from the oven and allow them to cool completely while they’re still in the pan.

Moving on to making some frosting; Take a bowl that’s safe for use, in the microwave and heat up heavy cream on high power for about 1 minute. Add semisweet chocolate chips to it. Let them sit undisturbed for 3 minutes before stirring until smooth.

Spread the chocolate ganache evenly over your brownies. Next, you can add a burst of color and flavor by sprinkling Wilton Rainbow Chip Crunch, M&Ms or your preferred candy toppings.

To allow the frosting to set beautifully chill your brownie pan in the refrigerator for 1 to 2 hours. Once ready cut these creations into 16 squares. These brownies are best enjoyed when chilled and make for a perfect dessert, on any occasion.
