These No-Bake Chocolate Peanut Butter Bars are thick, dense, and fudge-like. They're always a family favorite, and you only need five ingredients to make them.
Lightly grease a 13 x 9-inch baking pan with nonstick cooking spray.
MAKE PEANUT BUTTER LAYER:
Beat 1 ¼ cups peanut butter and butter until creamy and lightened in color with a mixer fitted with the paddle attachment or in a large bowl with a handheld mixer.
Gradually beat in powdered sugar. Mix in graham cracker crumbs.
Press the mixture evenly into the prepared pan. Smooth top with a rubber scraper.
MAKE CHOCOLATE LAYER:
Melt the remaining ¾ cup peanut butter and chocolate chips in a medium, heavy-duty saucepan over the low heat, stirring constantly, until smooth.
Spread the chocolate over the peanut butter mixture.
CHILL AND FINISH:
Refrigerate for at least 2 hours or until chocolate is firm.
Cut into bars.
Store in an airtight container in the refrigerator.
