Rice Krispies meet churros in this easy no-bake dessert bar.

They might look simple, but these churro rice krispies treats are, hands down, my most favorite recipe to date. I mean, I love all of my recipes but the combination of one of my favorite cereal bars with the cinnamon-sugar goodness of classic churros – well, it’s a match made in heaven!

The inspiration started with one of my favorite cookies from Crumbl Cookies: the churro sugar cookie. I love them so much, but they pack a serious calorie punch (800!), so I thought, why not turn the idea into a rice krispie treat? So, I assumed that inspiration and borrowed a few ingredients from my dulce rice krispie treats to create this whole new version.

I knew I could cut the calories but still have all the flavors of my favorite cookie combined with the crispy cereal and ooey-gooey marshmallows.

Easy Cinnamon Rice Krispie Treats

Beyond that, they combine my favorite Spanish donut and cereal bars, they are so easy to make. Just five ingredients!

They also take no time at all. In about 10 minutes, you’ll have a pan of the most fantastic rice krispie treats ever.

There’s cinnamon mixed into the bars, but I also add a cinnamon-sugar topping which makes them so much like a churro. It’s the perfect topping for marshmallow bars.

  • Salted butter
  • Rice Krispies cereal
  • Mini marshmallows
  • Cinnamon
  • Granulated sugar

Recipe Steps

Butter an 8×8″ baking pan.

Combine the cereal and cinnamon in a large bowl. Set this aside while you melt the butter and marshmallows.

Place the butter in a large pot and melt it over low heat. Add the marshmallows and stir until they are almost melted. I like leaving some marshmallow lumps so you get those nice gooey pulls when breaking the bars apart.

Take the pot off the heat and add the cinnamon cereal immediately. Quickly stir until the cereal is thoroughly mixed with the melted marshmallows.

Transfer the mixture to the prepared pan and press it into an even layer. To keep it all from sticking to your hands, use a spatula to push it into the pan.

Sprinkle the cinnamon sugar topping evenly over the bars. Allow the churro rice krispie bars to cool before slicing.

The key to making the best rice krispies treats is to work fast. Once the butter and marshmallows are melted, don’t wait to add the cereal. As the mixture cools, it will be harder to mix.

I think it’s easier to add the cereal to the melted marshmallows instead of the other way around. Use a large saucepan or pot that will hold everything when you mix.

Use very fresh marshmallows. Dried-out or stale marshmallows will melt, but when they cool, your bars will taste stale and won’t have that wonderful gooey marshmallow texture.

Store them in an airtight container at room temperature. I like to stack them in layers with wax paper, so they don’t stick. They will stay fresh for up to three days.
