Chocolate Truffle Crumb Bars

Total Time
Prep 10 mins

I needed to make a quick chocolate cookie to send to my godchild for her birthday. She is in college now (I feel so old) and she thought these were "the bomb" (her quote). I got this recipe from Camilla Saulsbury's Cake Mix Cookies book. Obviously, it travels well. Rich with a cake mix crust. I may have spent 10 minutes mixing these up.

Ingredients Nutrition

  • 1 (18 1/4 ounce) package chocolate cake mix (I used Duncan Hines Devil's Food)
  • 13 cup butter, melted
  • 1 large egg
  • 2 cups semi-sweet chocolate chips, divided
  • 1 (14 ounce) can sweetened condensed milk
  • 2 teaspoons vanilla extract
  • 1 cup walnuts, chopped (I left these out because she doesn't like nuts)


  1. Preheat oven to 350°F
  2. Spray the bottom only of a 13 x 9 inch baking pan with nonstick cooking spray.
  3. In a large bowl, place the cake mix, melted butter and egg.
  4. Blend 1 to 2 minutes with mixer set on medium speed until crumbly.
  5. Set aside 1 cup of the crumb mixture.
  6. Firmly press remaining crumb mixture into bottom of pan.
  7. Bake 15 minutes.
  8. In a medium saucepan, combine 1 cup of the chocolate chips and condensed milk.
  9. Warm over low heat, stirring until smooth.
  10. Remove from heat and stir in vanilla.
  11. Spread over hot crust.
  12. Stir walnuts and remaining 1 cup chocolate chips into reserved crumb mixture.
  13. Sprinkle over chocolate filling.
  14. Bake 25 to 28 minutes or until topping is firm to the touch.
  15. Transfer to wire rack and cool completely.
  16. Cut into bars.

These were rich and decadent.... and got gobbled up fast! I used almonds instead of walnuts, for preference. I did overbake mine a bit on the second oven time, so make sure to pull as soon as you think they're set! Made for ZWT7.

Sooo good! I used a triple chocolate fudge cake mix, and Scharffen Berger semisweet squares for the truffle layer. I didn't have any walnuts in the house, so I used pecans instead (half the amount). I would've left the nuts out completely, but I thought that they might be needed to cut the chocolaty-ness a bit. Loved the different textures in this. Thanks for posting!

Talk about your decadent chocolate heaven... These are wonderful with their gooey, ganache-y goodness. I made them using a milk chocolate cake mix, milk chocolate chips for the truffle layer (also added a couple T of rum to the truffle) and white chocolate chips for the crumb layer. I also used a mix of pecans and walnuts because I didn't quite have enough of the latter and I so love nuts and couldn't bear to put in less than called for. One word of caution: don't think you're going to be able to stop with just a bite....especially if you make the fatal mistake of trying them warm with a scoop of vanilla ice cream...
