These decadent brownies have three layers of peanut butter: a peanut butter brownie base, peanut butter chocolate frosting, and a peanut butter chocolate ganache.
Notes: For deep chocolate flavor, I like to use a 70% bittersweet chocolate here. Make sure brownies are completely cool before adding peanut butter layer, or the peanut butter layer will melt. After pouring the ganache layer on top, drag a small offset spatula across the ganache to make a design on top.
