I used the Ghiardelli mix for the base, the DdL ice cream, and whipped cream sweetened lightly with a bit of powdered sugar (thanks Karen). Lazy garnish was a sprinkling of chocolate mini-morsels. Looked fancy and was thoroughly enjoyed by all. I used a sharp knife to start the cuts, then pushed a bench scraper down to break through the brownie base. Next time I bake, I'll try Maria's Supernatural recipe.
