Chocolate Truffle Crumb Bars

READY IN: 55mins
Recipe by mary winecoff

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.

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.
