Bake up some bliss with these Homemade Little Debbie Fudge Brownies—thick, dense delights topped with a creamy ganache and crunchy walnuts. Every bite takes your right back to childhood.
Preheat oven to 350 degrees Fahrenheit (177 degrees Celsius). Line a 9x13" baking dish with foil and lightly spray with a baking spray such as Pam, then set aside.
In the bowl of a stand mixer, beat melted butter, sugars, and vanilla until light and fluffy, about 2 minutes. Add eggs and yolk, one at a time, mixing until incorporated.
In a medium-sized mixing bowl, whisk together flour, cocoa powder, baking powder, cornstarch, and salt. With the mixing speed on low, alternate adding dry ingredients and milk. Mix just until combined.
Remove bowl from stand and pour batter into prepared pan. The batter will be thick, so using a rubber spatula, spread it into an even layer. Place in oven and bake for 18-22 minutes. The brownies will be done, so do not over-bake or you will have dry brownies! Remove from oven and allow to cool in the pan.
Meanwhile, to prepare the ganache, in a 2-cup glass measuring cup, combine chocolate chips and heavy cream. Microwave on half power (mine is usually power 10, so I did 5) for one minute, stir, then repeat. Stir chocolate until all of the chips are melted and it becomes smooth. Beat for 1 minute and then pour over the top of the brownies. Spread evenly and sprinkle with chopped walnuts. Cover and place in the refrigerator to allow the topping to set for at least 30 minutes.
