They were okay.. they were much too cakey for my liking and to me they were dry. Unlike some of the other reviewers..I could tell they were "light" brownies. Not a complete waste but not worth making again.
Since other people said this recipe has a tendency to come out dry and hard to mix, I made it using a stand mixer and used 1/3 of a cup of coffee items (1/4c of coffee water from a half a packet of instant coffee, and the remainder made from kaluha). This had a nice side benefit of making the mixture moister. However, it increased the baking time by almost double. Just keep a keen eye on your brownies!
Your note to store leftover brownies went unheeded.. there simply were no leftovers! Cofee, toffee and chocolate are a dynamite combination for the holidays. All of the flavors were balanced and the batter produced a lovely rich cake like texture. Yummy!
I don't know what about these brownies are light because they sure don't taste like light brownies. They were exceptionally easy to make and very delicious. I brought them into work as a treat and was told they were definitely 'keepers!" I used instant espresso and it just enhance the chocolate flavor, didn't overpower with a coffee taste. I love adding espresso to my baking, it just makes the chocolate deeper for some reason.
These brownies do not taste light at all. They were easy to make. I did not have instant coffee so I used added the amount of water. They were great without the coffee. I love toffee and so these really hit the spot. Everyone who I shared them with loved them and did not think they were light either.
