These Lemon Crunch Cookies are delightfully lemon-y with a chewy crispy crunch provided by the Rice Krispies in the batter. If you’re looking for a simple dessert to take to a barbeque or a soccer game, look no further!
These cookies are a recipe from the shoebox of recipes my Grandma left me, and I’m honestly surprised they weren’t the first recipe I made. Anything with lemon in it gets automatically earmarked, but I guess these got overlooked by other, flashier recipes.
Now that I’ve had them though, it wont be long before I make them again. Using lemon cake mix as the base of the recipe means that these come together incredibly quickly and easily, and the addition of the Rice Krispies cereal elevates them above an average lemon cookie.

What Makes Lemon Crisp Cookies Special
- Box cake mix means they’re SUPER easy to make
- Crisp and delicious lemon flavor
- Soft and chewy on the inside, crisp on the edges
Ingredient List
Lemon Cake Mix – the base of the recipe.
Rice Krispies – you could substitute Frosted Flakes or Corn Flakes instead if you don’t have Rice Krispies – just crush them up a bit before adding.
Butter – always use the best quality butter you can afford.
Lemon Zest – if you don’t have a fresh lemon on hand you could substitute ½ a teaspoon of lemon extract instead, or just leave it out entirely.

Tips and Tricks
- Don’t overmix your batter – overmixing leads to tougher cookies. For the lightest, fluffiest cookie, you want to mix only until things are just combined.
- Under bake your cookies – cookies will harden as they cool, and as they sit. The best way to ensure a chewy center is to under bake the cookies by about a minute. The cookies should look almost raw as you take them out of the oven, but will continue to bake as they cool, and you’ll be left with a perfectly chewy cookie.

Storing Leftovers
Because the fat in these is all from butter, they do harden up after about a day – they are best on the day they’re made. They'll last at most 2 or 3 days at room temperature.

Lemon Crisp Cookies
Ingredients
- 1 package Lemon Cake mix
- 1 cup Rice Krispies cereal
- ½ cup unsalted butter melted
- 1 egg
- 1 teaspoon lemon zest
Instructions
- Preheat the oven to 350.
- In a large bowl, mix together all ingredients (mixture will be crumbly)

- Remove the cookies to a cooling rack as soon as they come out of the oven.
Hint for ALL homemade cookies! Put a slice of fresh white bread in a container that you are using with a sealable lid. Cover the slice with a paper towel or wax paper etc...then put all the cookies 🍪 on top,.seal it. Next.day, those hard cookies will be soft,.and the bread 🍞 absorbed it. Very handy for oatmeal cookies too. Always use parchment paper when baking, slightly underbake, and turn the cookie sheet 1/4 turn halfway through baking.
Not sure what website pointed me to this recipe but so glad I gave it a try!
Have made it twice for two different sets of friends and it has been a BIG HIT! And so easy.
We found them exceptionally tasty and crispy even after a couple days in the Tupperware. (I separated layers of cookies with the parchment paper) They may keep just as good for longer but I can't prove that yet because they get eaten before I can test the theory.
THANK YOU, Sara.🤩
Oh, I'm so glad you like them! They're some of my absolute favorites!!!
