I generally make my own desserts on my birthday, because it gives me an excuse to try something new. This year, I made two treats.
The first was a chocolate and coconut pie by Martha Stewart: http://www.styleathome.com/food-and-entertaining/recipes/recipe-martha-stewart-s-crisp-coconut-and-chocolate-pie/a/34855
It was good, but I had a couple issues. 1. The coconut in the food processor never formed a ball for me. 2. I used (not great quality) chocolate chips for the chocolate, because that was what I had, and I think that was a mistake.
The second were these salted Pretzel-marshmallow bars, which just sounded so crazy I had to try them: http://www.foodnetwork.com/recipes/food-network-kitchens/salted-pretzel-marshmallow-bars-recipe/index.html
They were amazing. Highly recommended if you like salty and sweet and blondies. Yum!
