Preparation Steps:

• Preheat your oven to 350°F (175°C). Line a 9x13 inch baking pan with parchment paper, leaving some overhang on the sides for easy removal later.
• In a large mixing bowl, combine the unsweetened cocoa powder, granulated sugar, brown sugar, and dash of salt. Whisk these dry ingredients together until well combined.
• Add the melted butter, vanilla extract, and flour to the dry ingredients. Mix until just combined, being careful not to overmix.
• Pour the brownie batter into the prepared baking pan and spread it evenly. Bake in the preheated oven for 20-25 minutes or until a toothpick inserted in the center comes out with a few moist crumbs. Let it cool completely in the pan.
• In another bowl, combine the creamy peanut butter, Rice Krispies cereal, powdered sugar, and vanilla extract. Melt the 3 tablespoons of unsalted butter and mix it into the truffle mixture until everything is well combined and sticky.
• Once the brownie layer has cooled, scoop the peanut butter truffle mixture on top. Press it down gently to create an even layer.
• In a double boiler or a microwave-safe bowl, melt the semi-sweet chocolate chips or chocolate candy coating until smooth. If using a microwave, heat in 30-second intervals, stirring in between until fully melted.
• Pour the melted chocolate over the peanut butter truffle layer, spreading it out evenly. Let it set at room temperature or refrigerate for about 30 minutes until the chocolate is firm.
• Once set, lift the bars out of the pan using the parchment overhang. Cut them into squares or rectangles. Serve and enjoy your delicious Peanut Butter Brownie Truffle Bars!
