The good thing about brownies, and all desserts in general, is that it very little can ruin your mood when you're biting in! I believe that these Peanut Butter & Caramel Swirl Brownies are the epitome of comfort food. Imagine the salty crunch of peanut butter, gooey dulce de leche caramel, and espresso powder all mixed together into a brownie! If you look up the phrase "Pick-me-up" in the dictionary, there will be a picture of these brownies. Corny joke? (Thx MissInTheKitchen)
