How to Make Sugar Free Rice Krispie Treats.
- Prepare. Prepare a baking dish for nonstick. Greasing the baking dish is commonly done. However, I am all for easy clean ups and making life easier and as a result, I am throwing in the option of using wax paper, foil or parchment paper that also extends over the sides of baking dish (you can give it a quick spray too). This will allow you to simply lift the treats out of the baking dish to cut into servings in the end.
- Melt. Once your baking dish has been prepped, use a saucepan on low heat to melt your butter. Once the butter has melted you can stir in the marshmallows. Continue to stir as the ingredients melt together.
- Combine. When the marshmallow have been completely melted into the butter, remove the pan from the heat and stir in the cereal and vanilla. You can use a rubber spatula or similar item to do this.
- Transfer. Use the backside of the spatula or your hands to press the mixture into the prepared pan from the first step.
- Set. Allow the treats to set before cutting into servings.
Expert tip ๐ It is recommended that you melt the marshmallows and butter on a stove top rather than in a microwave. This is because sugar free marshmallows tend to melt differently from regular marshmallows and as a result, you will need to keep an eye on them.
Tips for making krispie cereal treats.
Sugar free marshmallows are structurally different from regular marshmallows due to the difference in ingredients (corn syrup and sugar). This means that sugar free marshmallows tend to melt faster than regular marshmallows, which is something to keep in mind when making this recipe.
More helpful tips for you.
- Regular Rice Krispie Cereal, as just under four grams of sugar per serving. However,Rice Krispie Cereal is also available in Gluten Free (1 gram of sugar) which you can find online.
- This recipe can also be made keto or low in carbohydrates. Simply use a crispy keto low carb cereal that is similar to krispies.
- Prepping you pan well can be important in this recipe. I like to use parchment paper that is also sprayed with a bit of nonstick for a recipe such as this one.
- Use a well greased back side of a rubber spatula to press your mixture into your prepared pan to help prevent sticking.
- Because there is no sugar in sugar free marshmallows, this recipe will not be 100% the same as regular krispie treat recipes. I find that some no added sugar marshmallows do better than others when it comes to melting perfectly for this recipe. Look for marshmallows that can melt evenly.
How to store sugar free Krispie Treats.
These krispie treats should be stored in an airtight container, with parchment paper between layers, and refrigerated or frozen. If properly stored, they should should keep for about a week and a half refrigerated or longer when frozen.
