This is a take on my favorite blondie recipe after one of our commenters mentioned mixing in some lemon and mascarpone cheese. I was intrigued at the idea and went ahead and gave them a try.

They are, to be succinct, astoundingly good!

Creamy, sweet, very soft and with a bit of zing from the lemon they're incredibly rich with a lot of flavor. A cookie that's sure to satisfy the most insatiable sweet tooth.
