Sweet with a hint of tartness, these bright Lemon Rice Krispie Treats are a twist on a classic. Perfect for spring or summertime, just like my Perfect Lemon Bars!
Lemon Extract, Juice, or Zest
I use lemon extract in this recipe because it gives the whole thing a nice bright concentration of lemon flavor. However, that doesn’t mean you can’t use lemon juice or zest! Keep in mind you will have to use more lemon juice and/or zest to achieve the same intensity as lemon extract.
For this recipe you can use any of these options:
- 1/2 teaspoon lemon extract
- 1 teaspoon lemon zest
- 2 tablespoons lemon juice
Do I have to use lemons?
No! This lemon rice Krispie treats recipe could easily turn into orange, lime, grapefruit, or whatever other citrus you can think of. Simply replace 1:1 extract, juice, and/or zest with your choice of citrus!
Browned Butter
Browning butter is basically melting and cooking butter until the milk solids separate and toast up nicely. The butter will go through a couple of different stages before it’s done. First, it will melt, get bubbly, then foamy, and then finally you will see the butter turn a nice amber color.
I love to brown my butter for this recipe. It leaves a slightly toasty nutty taste that surprisingly pairs really well with the lemon flavor! If you don’t want to brown your butter, you don’t have to. To each their own 🙂
How to Make Lemon Rice Krispie Treats
For full details on how to make Lemon Rice Krispie Treats see the recipe card down below 🙂
Prep
Spray an 8×8 pan with nonstick cooking spray and set aside. Also, spray a medium pot and a rubber scraper with nonstick cooking spray.
Can I double the recipe?
Absolutely! To double the recipe prep a 9×18 glass baking dish instead of an 8×8 and double each ingredient.
Brown the Butter
In a medium pot, melt butter over medium-low heat. Continue to cook butter, swirling occasionally until golden brown, 7 minutes or so.
Add Ingredients
Stir in marshmallows and stir until completely melted. Stir in lemon extract then remove from heat. Pour in cereal and stir to coat in melted marshmallows. Once coated, pour the mixture into the prepared 8×8 pan.
Do I have to completely melt all of the marshmallows?
Nope! If you like having some unmelted marshmallow bits left in your rice Krispie mixture simply reserve 1/2 cup of marshmallows when initially adding them to the recipe. After taking the mixture off heat add cereal and reserved marshmallows and mix briefly. They will melt slightly from the heat, but not completely which is what you want.
Press Into Pan
Using lightly greased fingers, press bars down to flatten the top. Cool 15-30 minutes before cutting into squares.
Optional Toppings
Before cutting into bars, consider topping your lemon rice Krispie treats with any of these options!
- white chocolate drizzle
- lemon icing
- lemon zest
- lemon peel

I have a question. Just curious if we can use real lemon juice and lemon zest instead of extract? My daughter is 6 and always has fresh lemons 🍋 handy lol
Lemon, yes! Browned butter, yes, yes! But, Lauren, do try with citrusy cereal bits. A little snap of citrus in bites of crispies. Plus the little spots of orange, yellow and green.
I saw this and had to try it! OMG! Now I am addicted…they are soooooo good! I didn’t have lemon extract so I finely grated the rind from 1 lemon along with the juice, which I added to the browned butter and they turned out AWESOME!
These sound amazing! I love the idea of browned butter and lemon together!
Oh. My. Gosh.
I must make these, after my wedding… Can’t have rice crispy’s showing when I wear my strapless gown.. HAHA
Sounds so good! Definitely will try it out!
Whoa. I don’t know anything about screaming or non-screaming babies, but not being able to eat chocolate sounds wild!! Thank goodness you can still add lemon to your sweets.
Now THESE are my kind of krispie treat! Lemon and browned butter make my world go round!
Thank you Lauren for making life easy, always have a hard time thinking of what to make for dinner,love you and your beautiful family especially the new baby.❤
Browned butter! Heck yes!! Perfect summer treat!
