This Easy Recipe for Sugar-Free, Low Carb Peanut Butter Mousse takes just minutes to prepare and requires just 4 Ingredients! Easy substitutes to make this Peanut Free!

When you take just 4 simple ingredients and can turn them into a no bake dessert that tastes like a peanut butter cup in creamy mousse form, it’s priceless! If you’re all ready on board with a low carb, sugar-free way of eating these ingredients will all ready be in your fridge and pantry. With one simple substitute you can also make this peanut free if needed!

I adapted my No Bake Peanut Butter Cheesecake Mousse Pie to make this easy recipe for you today! No crust needed! Toppings are optional!

Making no bake recipes in the summer is how I like to roll! Actually I like no bake recipes any time of year and mousse is my favorite!  Nothing artificial, no additives, just simple and spectacular for a mousse that will have even your non sugar-free friends won over!

No Sugar Added Peanut Butter isn’t hard to find in most markets today. I usually buy it at Whole Foods, but online through Amazon, this is the Peanut Butter brand I love, nothing but peanuts and salt and super creamy.

If you’re not a fan of peanut butter, you can simply swap it with your choice of nut butter, like Almond butter, Cashew butter or Sunbutter made from sunflower seeds for a nut free version!

My boys couldn’t try this dessert because they have peanut and tree nut allergies but my hubby, sister in law and daughter were the taste testers.

Hubby said, “You should rename this PEANUT BUTTER CUP MOUSSE because it tastes JUST like one with the toppings!”

He thought is was so peanut buttery and did not notice any aftertaste which seems to always be his problem with stevia when I make a no bake recipe like this. He was pleasantly surprised! My daughter and sister in law absolutely loved it as well! Winning for all of us!

I hope you love this super creamy peanut butter creation as much as we did!
