Diet Coke Butterscotch Brownies


diet coke butterscotch brownies

On Monday, I shared a Coca-Cola Barbeque Chicken recipe.  To go along with my Coca-Cola dinner, I made Diet Coke Butterscotch Brownies. The base of this recipe is all over the internet lately.  I decided to take it up a notch and mix in some butterscotch chocolate candy that I had lying around.

To be honest, I have given up Diet Coke.  I am not a coffee drinker, so Diet Coke was my caffeine, and my start to the day. In February I decided I needed to cut it out of my diet.  It was embarrassingly hard to quit, but I did it!  Now I enjoy the occasional one maybe once every few weeks, but that is it.  I had to buy a small bottle to make these brownies, so I wouldn’t drink a whole case or a whole 2 liter bottle :)

These brownies are more of a cake like consistency.  They are extremely moist.  So much so, that they are difficult to cut.  I recommend refrigerating them to get them more solid, before slicing.  Without the added candy they are only 115 calories a serving, so they are much lower in calories than a traditional brownie. We had been to Ikea and bought a bag of their chocolate coated butterscotch candies, and they needed to go before I ate them all.  They did add great flavor to these.  You could use butterscotch chips if you wanted, or just leave them out.

  1. You’re not kidding about how moist they are – wow!

  2. they do look incredibly moist and oh so decadent! :)

  3. Once in awhile I treat myself to a diet coke, they are refreshing! Very nice chocolate treat, without too many calories;-)

  4. Erin I love your coke + diet coke recipes these past few days! I’ve seen these brownies before… but have never tried one! Definitely healthier than a regular brownie.

  5. Yeah, Diet Coke is my crack. I’m a bit ashamed. I’ve tried giving it up and I got headaches…which should tell me something.

    I think I’ll heal myself with these brownies! 😀

  6. UM WHOA! I am totally doing this!

  7. They look awesome! Great recipe, Erin!

  8. These look amazingly fudgy – my kind of brownie!

  9. The more I see this kind of recipe, the more I want to try it! These look so darn good!

  10. The fact that I just about hurt myself clicking to this page when I saw the words Diet Coke tells you how deep my addiction runs. I only allow myself one a day though (and the last sip is sitting in the glass right next to me as we ‘speak’). To be able to use my beloved beverage in a baked treat is a true gift. The brownies look absolutely decadent.

  11. yum! i’ve seen these coming across the food blogs, too, + have been wanting to try ’em. love the addition of butterscotch!

  12. What an interesting recipe :)

  13. Mmm I made diet coke brownies recently and they were really very good! Definitely a fun recipe to try! :)

  14. What a great way to use a can of soda. :) Looks very fudgy. :)

  15. I have definitely seen these around, especially on Pinterest. I like rich, dense brownies so after your description I don’t think I would like them. Congrats on cutting out diet coke.

  16. What a fudgy and delicious brownie flavour combo 😀
    Love it!

  27. How creative! I can’t believe they look so decadent and are so not!

  28. So I tried making this last night, using root beer instead, but the batter was more of a cake batter consistency so all the chips sunk to the bottom and it took almost twice as long to cook. I used 12 oz of root beer idk what went wrong. But they still tasted wonderful!
