Birthday cake topped with sweets

If you want to bake sth special for somebody who is going to celebrate birthsday, I have an idea for you!
It is very simple, but tasty and you can use different kind of sweets to make a decoration.
I used Schocko-Bons, Snickers and M&M's.
I baked a brownie (you can use your favourite recipe), I put mixed mascarpone with peanut butter and sweets on the top. That's it!
