Low carb rice krispies treats


There are certain snacks I miss when it comes to eating low carb, and carb counting. Rice crispies treats are one of them!

I’m personally very insulin resistant.

My body has trouble utilizing the insulin I do produce, and simple carbs like flour and sugar have an immediate effect on my blood sugar.

I ALWAYS spike. when I eat carbs.

Carbs are not all created equally, and they are not all bad. But I do find that I’m very sensitive to carbs, so I stay within a range of what I allow each day.

How I ended up making low carb rice krispies treats

My friends at HighKey snacks always send me goodies to try out. I’m absolutely obsessed with their snacks.

They’re low carb versions over everything I like – muffins, granola, and their latest – protein cereal.

I asked my husband if he was up for my experiment, and my mad science experiment was well worth it. These low carb rice krispies treats are awesome!

If you want to try a low carb version, these look promising, but they do contain malitol, which can still spike blood sugar for some.

Check out the recipe below! Let me know in the comments section if you give this a try. I’m curious about what you think!
