Irresistible Tiramisu

I've been working in a new department for 5 months already, and I'm very happy that I've made many new friends (co-workers). As all of us are in similar age, so we get along very well that we like to do lots of activities outside of work hours... like golfing, tennis, dinner, shopping etc..

Moreover, I can practice my baking skills by making birthday cake for my co-workers, and I really treasure this opportunity which it'll help to improve my skills! Last month, I've made a Banana Oreo Cheesecake for the birthday guy, and this month, I've made a Tiramisu for my trainer! I'm very happy that they enjoyed it alot! and I've promised my co-worker to post the recipe here, hope you'll enjoy making it and your friends will like it!
