I adapted my No Bake Peanut Butter Cheesecake Mousse Pie to make this easy recipe for you today! No crust needed! Toppings are optional!
UNSWEETENED PEANUT BUTTER
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.
SWAPS FOR PEANUT BUTTER
If you're not a fan of peanut butter, you can simply swap it with your choice of nut butter, like, Macadamia Butter, Almond butter, Cashew butter or Sunbutter made from sunflower seeds for a nut free version!
PEANUT BUTTER CUP MOUSSE
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!
BEST LOW CARB SWEETENERS
If you're just not a fan of using liquid stevia as I have in this recipe, no problem! One of our newer favorite low carb sweeteners that doesn't leave an aftertaste, is Better than Sugar by Sweetleaf. They have a confectioners powdered sweetener which would be best for this recipe and they also have a granulated option. It's a combination of erythritol and stevia and has plenty of sweetness as sugar would provide. Swerve confectioners sweetener is also low carb, but doesn't have as much sweetness and you may need to use a bit more to get this as sweet as you like. Allulose would be another option, but again it isn't as sweet as using the Better than Sugar sweetener. Allulose comes in a liquid, which would probably work best in this recipe, but it also comes granulated if you prefer.
