Preheat your oven to 350ºF and line an 8x8-inch pan with parchment paper.
In a mixing bowl, combine all the dry ingredients and set aside.
Cream together the peanut butter, maple syrup, brown sugar, and vanilla until smooth. Then, add the eggs and almond milk, stirring until combined.
Mix the dry ingredients into the wet until well combined, then fold in the melted chocolate gently, leaving fudgy pockets throughout.
Transfer the batter into the lined pan, and top with extra chocolate chips if desired.
Bake for 35-40 minutes until the center is nearly set.
Let the brownies cool for a few minutes before transferring them to a rack. Serve warm with ice cream for a decadent treat, or let them cool completely before slicing into squares.
