Outrageous Caffeine Infused Brownies

These brownies seem to be very very popular. I've made them before following the original recipe - using just chocolate chips & walnuts. This time I had some left over caramel & thought it would be a great addition to this already fabulous brownie recipe. Instead of instant coffee, I used instant espresso & added some cappuccino chips.

**I got to sample some the day after & these are fabulous indeed. I haven't had many brownies, but the texture is perfect, in my opinion. The brownies were not too fudgy & dense, they were the perfect balance of cakey & light, considering the small amount of flour used, with just the right amount of chocolaty. My only complaint?...when the chocolate/sugar hit my teeth, I think I got a slight sugar/caffeine rush! OUCH, I think I have a cavity.
