Lemon Supreme Rice Krispies Treats

I’ve been on a lemon kick lately. I’m pretty sure it’s because warm weather is finally coming. One of my favorite things to drink is lemonade. When thinking about lemonade I think of refreshing and that’s exactly what these rice krispies treats are. No matter the temperature outside, when you bite into one of these bad boys it will feel like it’s the middle of summer.

      Hi Amy,
      Any brand will work. I just find Duncan Hines lemon to have the most flavor.
      If you can’t find any lemon cake mix try using a white cake mix with the zest of 3 lemons
      and also the juice from those 3 lemons. Hope this helps!
      Let me know how they turn out :)

        These are fantastic! I couldn’t find Duncan Hines at the store I went to – so I used Betty Crocker and a little more juice (bottled).

        AMAZING recipe. Definitely a keeper for us lemon lovers! Thank you for posting this!

    Are the marshmallows Mimi or regular size? I want to make these next week. We lose Rice Krispies treats, and these sound like CROWD PLEASERS!

    My daughter made these for me to take to a party. They were a HIT! Everybody loved them. I was sad that I hardly had any left to take home, heeheehee. Definitely will be making these again. Thank you for the recipe!

      It won’t have as much flavor but you can make them without the cake mix and use the zest of 4 lemons and the juice from 4 lemons. I hope you like them :)

    Oh, thanks for gluten free option! I was wondering how I could do that. Good thing I just bought a zester! My kids are home sick so I’m happy to induct them into the beautiful world of rice crispy treats!

      I’m going to try making these for the upcoming Memorial holiday weekend. They sound delicious. Recipe indicates 4 1/2 tbs (tablespoons) of butter; not pounds. :)

    I could never again, in good faith or conscience, eat a Rice Krispie treat in any other way than this. This recipe is divine!!!

    • Karissa Krishart says

      To be honest at first I thought this was going to be a rude comment, haha. I’m so glad you liked them Angela :)

    I am going to try making these for my sister’s birthday this weekend – she loves lemon! Just another tip: if you can’t find Lemon Cake Mix, just add 1 pkg of dry lemon pudding mix to a vanilla/white cake mix.

    Miss Karissa,
    I made these this morning. OMG (I don’t speak thusly, but I will now). I made a batch, waited a short time then cut two squares, one for me and one for DH. He picked his up set it down and said I will have to wait until this sets up. I with a mouthful (another thing I do not normally do) said it won’t change the taste any. He picked it up again and started to eat it. I walked away, went about my business, but they kept calling me. So as I am passing through area DH is in, he holds up his plate and say I wouldn’t be adverse to tasting another one of these. Oh said I, I thought you were waiting for them to set up. So right now of a 9×12, have eaten 1/2 the pan minus two squares. OMG these are to die for. Thank you for putting these out there.

    Made these this afternoon, and ooooh my goodness!! I love all things lemon, and I have to say, this is one tasty lemon treat!!

  12. DubNDub says

    I was excited to find these. I replaced the cake mix with 2 packs of instant lemon pudding. Will see what the volunteers think. Thank you.

    • Karissa Krishart says

      oops! That would be if you ate the whole entire pan yourself 😉 I forgot to put the amount of servings so it only counted it as 1. Thank you for catching that. I fixed it now :)

  13. Megan says

    I just made these, and they’re absolutely amazing! The only thing I did differently is I added a little bit of vanilla. Thanks for the great recipe!
