      Minus off the 45 sugar alcohols and the net carbs are 8 not 53. Still high for me but it would be great treat

    Pretty good flavor! I used 1 tsp of coconut flour and 1 tsp of liquid sweetener, and microwaved for 90 seconds. Next time, I'll swirl in the peanut butter and water mixture before microwaving.

        I’m allergic to almonds can you use another kind of flour?

          5 tablespoons of that swerve? That is absolutely ridiculous.

            Didn't use but 2 tbls and even that was more than it needed. I think that is a typo?

            I find it extremely sweet! Had to use half the amount in the recipe.

          I think I will use real peanut butter if I try it again. It needs some Keto ice cream.

            Should have only used 2T swerve. I could only eat half and it took double the time in the microwave to cook and I still had to give it 20 seconds for the half that was left so it wouldn't be liquidy.

                    This is my first dessert and it was good but VERY sweet and I only used 3 tablespoons of sweetener. Next time I’ll only use one. Overall it satisfied my monthly sweet splurge!

                      Can I bake this instead of Microwave? And if yes, what temperature and for how long?

                        You can bake in 15 till 20 minute I guess

                        Did you figure this out? I don't have a microwave and want to bake it in the oven too.

                      Delicious! I used 2 tablespoons of sweetener instead of 5 and it was still very sweet. Makes a lot of cake

                        Can you substitute peanut butter for the peanut butter powder? I cannot obtain it in my country.

                          So yummy and rich. Need a really big coffee cup for this. I used a small bowl. Could only eat half. Will be making again.

                            Like a warm delicious chocolate lava cake. I sprinkled some hemp hearts on top to boost the nutrition...yum!
