Based on this recipe.  I added raisins and about 2-3 tablespoons of peanut butter and left out the nuts.  We make do with a bag of chocolate chips rather than fuss with slabs of chocolate.  I bake them in 2 batches in a convection oven.  Fourteen minutes at 375° works in mine.  I swap shelves and rotate at the halfway mark.  Not sure if that’s really needed in the convection oven but it’s what I do and it works for me.
