Homemade chocolate fudge brownies topped with a thick layer of cookie butter frosting. If you like cookie butter, you will love this recipe! **Do not rely on the toothpick test to see if your brownies are done. To achieve a fudgy brownie, you must under bake them slightly. Once the edges are firm but the center still looks wet, it is time to remove them from the oven. Do not bake longer than 20 minutes.**
