Chocolate Collagen Brownie Cake

12 Brownies
45 Minutes

Biiiiig brownie gal over here. Especially brownies made from a box, ya know? In my opinion, homemade brownies surprisingly just do not compare. But I have finally done it! I have finally made the best brownies that taste very similar to a box mix. The only thing that makes them better than box? This glazed frosting. The frosting is the real star of the show on these brownies. It’s the perfect chocolatey, melty, glaze that will turn any normal brownie into a decadent CAKE. I love. No matter what brownie recipe you decide to use, you need to make this frosting!!!
