Chef Kate’s Goop Blondies

This morning I finally tried Chef Kate’s Blondies – a popular recipe from Goop. They were terrific, but I did scale the recipe down a bit because the original is baked in a 12×18 pan. That’s perfect for bake sales or large groups, but we weren’t sharing today. Scaled measurements are below, and I also made some flavor substitutions based on what was in the kitchen – chocolate chips in place of peanut butter chips and walnuts instead of coconut. I think the essence of Chef Kate’s recipe is still there, though. What really makes these special is the marshmallows. They melt into the blondies and add a little bit of chewy sweetness.

One final note, they tasted much better after they’d cooled.

    Its been forever since I baked Blondies, but this looks like a good recipe to try sometime. The top looks kind of crackly, which I like.

    I made these when I saw them on Goop and they were such a hit. Crazy hit, actually. I brought the chocolate marshmellow brownies tonight to a BBQ and our friend Doug said…what, no super duper crazy delicious blondies? Then he tried these. Both, FABULOUS!

    what I meant to say…then he tried the brownies, not Katie Lee blondies. He said both were fab and I have to agree though I think the blondies were a smidge better…but only a smidge.

    Lisa, I think the melted marshmallows helped make the top crackly.

    VG, how about a vegan blondie? I keep meanting to try those.

    Heidi, thanks for the link to Savory TV. Looks like a neat site.

    Louise, they were definitely good.

    Ellen, these are good blondies. In fact, I’m going to add them to the Top 5 list for now. Next time I’ll try them with the peanut butter chips and coconut.

    Once I saw the word ‘goop’, I knew I had to bookmark this! Those look and sound amazing! Cannot wait to try them!

    Several days ago I made the GOOP lemonade with agave syrup and it was very very good.

    I made these blondies today and I wasn’t entirely happy with the result. I made the full, 4-sticks of butter! (!!!) version in a sheet pan. 25 minutes of baking at 350 degrees, as Chef Kate’s recipe calls for, just wasn’t enough time. Unfortunately, I didn’t realize that the bars were undercooked until they had cooled and I had begun cutting them. So, they are VERY gooey–even the bottom didn’t bake enough. If I were to make the full recipe again I’d leave them in for another 7-10 minutes, probably.
    Also a note about the coconut–the original recipe calls for unsweetened coconut. I didn’t have any so I used sweetened. It works just fine.

    Jill, sorry you wasted all those ingredients. That’s one of the reasons I like making smaller batches of things I haven’t tested yet. Then again, lots of people liked the full batch version, so maybe it has to do with Kate’s oven. Maybe her oven and some of the other people’s ovens run hot. My small batch was done in 25 minutes.

    I’ve come to think of bake times as “suggestions” and always do a toothpick test when I can. Sometimes even the toothpick test doesn’t work.

    I hope you salvaged the ones around the edge.

    I want to make blondies this weekend and I can’t decide between the goop blondies or Katy’s favorite blondies. They both look wonderful.
    Do you have a favorite? I suppose I could make both and decide for myself.!!! Can’t have too many blondies!!!
