Cobblestone Blondies

1 cup flour
1 cup mini* semi-sweet chocolate chips
3/4 cup mini marshmallows
1/2 cup toffee chips
1/2 cup sugar
1/4 cup light brown sugar
6 tablespoons butter, at room temperature
2 eggs
1 teaspoon baking powder
1 teaspoon vanilla

Preheat oven to 350. Grease an 8×8 inch baking dish. In a large bowl, cream together the brown sugar, sugar and butter. Add the eggs and vanilla, beat until fluffy. Add the flour, 2/3 of the chocolate chips**, 1/2 of the marshmallows, all of the toffee bits and the baking powder until thoroughly combined. Pour into a prepared pan and bake 20 minutes or until just set. Sprinkle evenly with remaining marshmallows and chips, return to oven for an additional 5-10 minutes or until a toothpick inserted (not through a marshmallow!) comes out clean.

*Mini chips melt faster, but regular chips would work too.
**If you are using regular sized chips, you might want to add the chips after the flour so they don’t get broken up.

My thoughts:

Following in the great tradition of sweets on Gilmore night, I made these blondies. I called them “cobblestone” blondies because if they were chocolate and had nuts, they’d be “rocky road” brownies. Get it? Cobblestones, rocky road? Okay, maybe it isn’t that great of a name but I couldn’t think of a better, more descriptive name and I wanted to get them done before the show. They came out really yummy and don’t taste as over the top sweet as you might think from the ingredients list. They also have a really unique fluffy yet chewy texture.


  1. They look yummy! I like the toffee chips.

  2. I’m a sucker for marshmallows, especially with toffee chips. I think these sound wonderful.

  3. Around Halloween you should use colored marshmellows 😉

  4. these look scrumptious. but… I’ve never even seen toffee chips @ my local store! Where do you find them, and what brand are they? Merci!

  5. The name works for me! The marshmallows look wonderfully gooey.

  6. These look great!

    The summer I lived on Nantucket I ate tons of ‘cobblestone’ cookies from one of the local bakeries. (They’ve got cobblestone streets in Nantucket town.) It’s been a while, but I think they were oatmeal cookies with chocolate chips, nuts and golden raisins. Delish.

  7. mmmmm, yum. my husband would *love* those.

  8. You can buy toffee chips near chocolate chips at the grocery store. The ones I used are the Heath toffee chips and they are put out by Hershey. I have found them at Safeway in the past.

    Some times they are hard to find, however, I have notice that even stores that normally don’t stock them, sell them around Nov./Dec. for holiday baking. I stock up if they have good expiration dates. Also most recipes don’t call for much, I’ve used this same 10 oz bag for about 4 different recipes over several months.

  9. The “cobblestone” name is perfect–very creative. I have loved blondies since I went to school at Boston College where the dining hall made the most perfect blondie ever. These are very different, and the fluffy texture sounds really great.

  10. They look delicious! I also like the name.

  11. Okay, those just look too good to be true. I’m making them tomorrow!

    I found you through a link at Pinch My Salt and you know I’m going to have to stop doing a load of other stuff so I can try all the great recipes I’ve seen here and there.

  12. I am 25 years old and I have never cooked anything from ‘scratch’ in my life! I thought that this recipe would be a good starter for me. They turned out perfectly! I had to putz around with my oven and cook it longer than suggested, but otherwise it was great! I added coconut shreddings on the top and extra toffee pieces as well.


  13. Samantha: I am so happy you enjoyed them! Your variations sound great!

  14. I made this for our evening at the beach to watch fireworks. We invited a few friends and family members. It was a hit and even I loved it. Thank you for sharing this great recipe! :+)
