These brookies are soft and chewy, with peanut butter and chocolate married together in every bite. All you need is two bowls, and no mixer is required!
Preheat oven to 350F. Spray a 9×13-inch pan with cooking spray or line with foil and spray with cooking spray for easy cleanup.
Stir together the peanut butter, sugars, and egg in a large bowl.
Press the dough into the bottom of the prepared pan. The dough layer will be thin. It helps to spay your hands with cooking spray if using your hands, or use a spatula and take your time to spread it out; set aside.
Brownies
Melt the two chocolates (I used 4 ounces of Trader Joe’s 72% Pound Plus bar instead of two types of chocolate) and butter together in a large, microwave-safe bowl on high in 30-second increments, stirring between each, until the mixture is smooth.
Whisk in the sugar, eggs, and vanilla.
Carefully stir in the flour and salt, don’t overmix.
Evenly pour batter over peanut butter layer, lightly spreading it with a spatula.
Bake for about 32 to 38 minutes, until the top is no longer glossy and is slightly cracked around the edges.
Cool completely in pan before slicing and serving. Store in an airtight container for up to 5 days.
