  1. Is it possible to counteract the aftertaste of using zero-carb sweeteners? (Is that aftertaste something one gets used to eventually?) I always use less swerve/monk-fruit/stevia/allulose than any given recipe calls for, but the taste is still present. I tweak recipes. Add more fat or salt or combine sweeteners, I am at a loss for what to do. Is there anything that can be done other than adding trace amounts of cane sugar or maple syrup?

    As I side note: i don't have any dog deadly sweeteners on hand.

  2. This is definitely awesome and gives me an idea to make my own peanut butter Reese cups. Would make this and half the inch and in a silicone cup cake mold pour melted keto chocolates, place the peanut fudge and cover back with chocolate viola Atkins peanut butter cups but less expensive and more accessible for me

  3. Thiis is delicious! I didn’t have the collagen powder, but I did have a huge bag of peanut flour on hand that I rarely use. I made that substitution which made the fudge thicker (not pourable), but it went into the pan just fine and tastes great. I will try this recipe again with collagen, but I’m happy with the results. Thanks for this super easy recipe!!

  4. I followed the recipe to a T, but the only exception I made was instead of unflavored collagen, I used Perfect Keto peanut butter collagen powder, and used 1/2 cup powdered Swerve (since the PK is sweetened), and since my PB was unsalted, i added 1/2 tsp hemilayan pink salt. AND IT TURNED OUT AMAZING! Thanks, Caroline! Every one of your recipes have been scrumptious!

  5. Well girl look what you did to me now eating peanut butter makes me have joint pain I don’t know why it’s been happening the past five or so years but I still indulge in a little bit here and there because I love it so much so I made half a batch hopefully I can control myself so I won’t be in any pain the next couple days lol thank you for the recipe.
