Fudgy Chocolate Brownies with Ganache

Preheat oven to 350 degrees F. In a large microwaveable bowl, combine butter & chopped chocolate. Microwave for 2 minutes, then stir until chocolate & butter are melted and smooth. Stir in sugar & brown sugar and mix. Mix in eggs, yolk, and vanilla and mix until combined. Add flour and chocolate chips and mix well. Transfer to a parchment lined 9x13 baking pan and bake for 30-35 minutes. Remove from oven and poke holes over the surface using a fork. Allow to cool while making ganache topping. In another microwaveable bowl, add in chopped semisweet chocolate and cream. Microwave on high for 1 minute, then remove and let stand for 1 minute without disturbing. Whisk until the mixture is glossy and smooth. Pour the ganache over the brownies and spread into a smooth layer. Top with sprinkles, cut into squares, and enjoy!
