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.

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.

    These are so good! Great recipe. I put sliced almonds on top of the batter for a little bit of crunch. Love these easy and yummy recipes. Thanks!

    These were delicious, made exactly to the recipe. Like a lemon cheesecake combined with the texture of a brownie. Everyone I shared them with raved about them. I’ll definitely be making these again (and again and again).

    Meanwhile i made this recipe……
    Exactly what most people here say…..Very good.
    I just replaced the all-purpose flour with grinded oatmeal wich makes the batter a little brown-colored.Thats ok.
    The taste is still wow……
    I’ll make this gem more in the future.

    Hello there….the other day i came up this recipe.Looks awesome to me.But i am a little confused….
    In the ingredients list it says on the second line….
    “1 cup (220 g) of tightly packed dark brown sugar”
    And further down on the last line……
    “1 cup (128 g) of all-purpose flour”
    Its about those g(rams)…..” 1 cup (220 g)” and ” 1 cup (128 g)”

    Why the difference in grams?
    Can someone help me out plz?

    I plan to make this recipe coz it looks great

    We made this recipe and added pecans and walnuts and chocolate chunks instead of the butterscotch chips. We cooked them for 20 minutes and they were very beautiful. They were so amazing! I highly recommend this recipe!
