Ingredients You Need for This:

This Zesty Lemon Rice Krispie Treats ingredient list is short but mighty! Here’s what you want to have on hand:
- 6 cups Rice Krispies cereal (the crunchy foundation you know and love)
- 4 cups mini marshmallows (fresh is best! No stale marshmallows allowed in these tangy lemon marshmallow treats)
- 6 tablespoons unsalted butter (whole flavor, no substitutes here)
- 1 tablespoon finely grated lemon zest (this is your flavor bomb—the secret to epic Zesty Lemon Rice Krispie Treats)
- 2 teaspoons fresh lemon juice (brightness that balances sweetness perfectly)
- 1/2 teaspoon salt (to make all the flavors pop)
- Optional: 1 teaspoon vanilla extract (adds depth to your citrus marshmallow snacks if you want to get fancy)
Game-changer alert: Skip the regular lemon extract and use fresh lemon zest and juice instead. It makes your Zesty Lemon Rice Krispie Treats burst with authentic, tangy flavor that punches through the sweetness. Your taste buds will thank you!
For sourcing your ingredients, hit your local grocery’s fresh produce section for lemons with vibrant, bright skins — these pack the most zing. And don’t skimp on the butter; splurge a little on unsalted European-style butter for that rich creaminess that levels up every bite.
If you’re on a budget, no worries. You can swap out the mini marshmallows for regular-sized chopped marshmallows, but adjust the melting time a bit. Just make sure your Rice Krispies cereal stays crisp and fresh – stale cereal means sad, soggy bars.
Pro tip: Keep your lemon zest ready in a small container so you can whip up this recipe on a whim. These zesty citrus cereal bars come together in a flash once your ingredients are prepped!
If you’re into trying variations, I’ve tested adding a sprinkle of crushed pistachios for crunch or swapping lemon zest for lime for a twist on the tangy lemon marshmallow treats. Both gave me rave reviews from my flavor adventurers.
