Prepare the brownie base. Preheat oven to 325°F (165 degrees Celsius). Line a 9-inch (23-centimeter) square pan with parchment paper. (see image)
Melt chocolate in microwave. Add coconut oil and mix to combine. Set aside.
In a mixing bowl, combine sugars and eggs in your mixing bowl and beat until thick. Add chocolate mixture and vanilla. Add the flour, cocoa, salt, and coffee and mix just until a thick batter is formed. Pour into prepared pan. Smooth top.
Place dollops of peanut butter all over batter, then swirl.
Bake for 20 minutes. Remove from pan and cool. Cut into 16 squares.
Prepare the Ice Cream. Fold the peanut butter bites or peanut chew pieces into the slightly melted ice cream. Cover and return to freezer.
Prepare the sauce. Combine all sauce ingredients in a small bowl. Microwave until chocolate is melted and all ingredients are combined. (Pour into 2 small round foil pans to freeze, and it is easy to warm on the blech.)
To Serve, place a brownie on a plate. Top with a scoop of ice cream and drizzle warm sauce on top. Tip: Serve the brownie warm and it’s even better (keep warm on blech).
