Yes, I know there are plenty of Rice Krispie recipes out there. However, the difference in this recipe is that I used an entire can of sweetened condensed milk. Yes, I said an entire 14-ounce can! The end result is a super sweet treat that stays super soft & gooey! And, if you feel motivated, make your own homemade marshmallows to use. I also have Fluffernutter Rice Krispie Bars that have added peanut butter and marshmallow fluff which are incredible!

Bars Ingredients

Sweetened Condensed Milk: If a little is good, a lot must be great, right? Well, in this case, it is. Many recipes use just 1/2 cup of sweetened condensed milk, but trust me, you want to use the whole can! Be sure to check the labels carefully when buying sweetened condensed milk. Do not use evaporated milk in this recipe.

Butter: I used unsalted butter, but you can absolutely use salted if that is what you have on hand.

Do I Have to Use the Entire Can of Sweetened Condensed Milk?

You don’t have to use the whole can; you GET to! Using the entire can makes the treat extra sweet and ooey-gooey and keeps them soft a little bit longer.

Can I Make Rice Krispie Bars in a Different Sized Pan?

Yes! I wanted the bars to be nice and thick, so I used an 8×8-inch baking dish. You could use a 9×9-inch dish or even a 9×13-inch baking dish. However, the bars will be quite a bit thinner.

Can I Freeze Soft Rice Krispie Bars?

Yes! Let the bars cool completely. Then, cut them into individual bars and wrap each in plastic wrap. Finally, store the wrapped bars in a freezer-safe bag for up to 3-4 months. Be sure to label and date the packaging.

Soft Rice Krispie Bars are the sweetest and softest Rice Krispie bars you will ever make because of one special ingredient!


  • 3 tablespoons unsalted butter
  • 1 can (14 ounces) sweetened condensed milk
  • 1 bag (10 ounces) miniature marshmallows
  • 6 cups (174 g) rice cereal


  • Spray an 8×8-inch baking dish with nonstick cooking spray. Set aside.
  • In a large pot over medium heat, melt butter. Add sweetened condensed milk and stir to combine. Bring the mixture to a simmer, stirring constantly to prevent burning.
  • Add marshmallows, stirring frequently until melted.
  • Remove the pot from heat and fold in the rice cereal with a clean rubber spatula (I like to spray the spatula with nonstick spray to prevent sticking). Stir until well coated.
  • Transfer mixture into the prepared baking dish and press into an even layer.
  • Allow the bars to cool to room temperature before cutting and serving.

  1. I’m not sure the traditional rice crispies recipe needed improvement, but I tried this one. The additional liquid from the condensed milk changed the texture of the rice cereal and made it very chewy (not in a good way). If it’s not broke, don’t fix it! Love all of your other recipes that I’ve tried though.

  2. Delicious! I added 8 cups of cereal and that stretched out the condensed milk perfectly. Thanks for another winner!

      1. Wish I read that first. 6 cups and the cereal was so chewy, not in a good way, like stale old cereal texture. I normally really enjoy these recipes, as is.

  3. I am gluten free so these Rice Krispy bars are one of my favorite treat! My all time fav is adding crushed candy canes in them. Peppermint makes them so awesome!! And they are good all year long, not just at Christmas!

  4. I felt this recipe was a bit too gooey. It wouldn’t hold form. So I added in an extra cup of cereal and that seemed to improve it.

  5. I only use 1/2 can of SCM. But you have to brown the butter, add vanilla and coarse kosher salt. Just trust me.

    1. I tested that (as you can read in the post) and didn’t like the results. But I am glad you found the perfect amount for you!

  6. Can I use this as the crust for my cheesecakes? I have made cheesecakes this way but not with the condensed milk.
