Guest author Garrett McCord brought these blondies over the other day, a variation of the blondies he made a few months ago. They were outstanding. They lasted all of 20 minutes. My father is still waiting for Garrett to bring him another batch. ~Elise

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.

    Yum! I’ve been looking around for a good blonde recipe, and I think this is the winner. I had the most delicious mascarpone cheesecake last week, and now all I want is to experiment more with it. :)

    Hello. This is the first time I am commenting on this site, however, I take all my recipes from this blog because they have ALL turned out great! My husband made these for me last week, and I have to say they are the best treat I have ever eaten. He follows directions exactly and they looked just like the picture. They are very rich and dense which is what I love. I don’t think they were too buttery. I have a convection oven and it took the whole 30 minutes to bake. Thanks for a great blog!

    These were quite delicious and different from anything I’ve ever eaten before. The closest comparison I could make would be a cross between a lemon bar (from the creaminess of the mascarpone) and a lemon cake (from the dense, but cake-like texture). The flavor was amazing, very lemony. The texture was moist, but a bit too buttery. I wonder if cutting the amount of butter would disturb anything… This was a great and very unique creation! I would definitely make these again, but try cutting the butter.

    There were scrumptious – a little cakey but when I make them again I’ll rework the baking soda. I have a meyer lemon tree and am always looking for recipes with lemon. thank you!
