Recipe by Bruce Gurnick
READY IN: 55mins
SERVES: 20-24


  • 1
    (18 1/4 ounce) package chocolate cake mix (experimenting with other cake flavors is OK)
  • 14
    cup vegetable oil
  • 1
    large egg
  • 1
    cup dry roasted peanuts
  • 1
    (14 ounce) can sweetened condensed milk
  • 12
    cup creamy peanut butter (or crunchy)
  • 12
    ounces semi-sweet chocolate chips
  • 12
    ounce cooking spray


  • Heat oven to 350°F
  • Coat a 9x13" baking pan lightly with non-stick cooking spray.
  • Beat cake mix, oil and egg in large mixing bowl, on medium speed until somewhat crumbly. Add peanuts and stir. Measure out and set aside 1 1/2 cups of the cake crumb peanut mixture to be used later. Pour remaining mixture into prepared pan and press out to evenly cover the bottom of the pan.
  • Beat sweetened condensed milk and peanut butter in a medium bowl until smooth (hint: use the same bowl you used for cake crumbs). Spread this over the prepared cake crust. This will be a bit challenging. Be careful but don't worry if you struggle with the cake layer a bit.
  • After spreading the mixture sprinkle about 4 oz of semi sweet chocolate chips evenly over the peanut butter mixture.
  • Pour reserved cake crumb mixture over the top and spread evenly, pressing down gently.
  • Bake 25 - 30 minutes until set. Remove from oven. Turn oven off. Top with Remaining about 6 oz more of chocolate chips. Return to oven for 1 minute and then remove from oven. Use a spatula to spread the chocolate evenly over the top of the bars. Cool and store in covered container. Enjoy.
  • Note: You can be creative with this recipe. The cake flavor may be changed. Other flavor chips may be substituted for chocolate. Other nuts may be substituted or combined for/with peanuts. Other nut butters may be substituted for peanut butter. This one basic recipe can produce many bar variations.
