I didn't add the heavy cream to the sauce because I thought there was enough going on in the dish and wanted to keep it more acidic or tart from the tomato base. This was a good move for me but feel free to follow the recipe to a tee. I also used 1 pound of beef instead of .5 lbs. which definitely made the dish extra saucy. We ate the extra sauce with ciabatta bread.
Oh, and someone who doesn't love brownies but loves lemon bars, these lemon brownies were a great mix of both! And super easy to throw together :)
This was also probably the only time I had to double the icing recipe (I usually halve it because most recipes make way too much icing!
