Keep the squares in the refrigerator so they remain solid, but you can take a few out an hour before you eat them if you want them to be a little softer.
You can use any nut butter you prefer, such as almond butter, cashew butter or coconut almond butter. I don’t recommend peanut butter as it is high in inflammatory omega 6 fats and mycotoxins.
For sweetener, these are quite good without any, but if you do want one, I like stevia the best as it is sugar free and has a great flavor when mixed with a slight dash of salt to take out any sort of bitter after taste.
If you want another option other than stevia, I like monk fruit as it is sugar-free as well. If you choose to use honey, maple syrup or coconut sugar, these will elevate your blood sugar and this will not be a ketogenic recipe.
You could also try a sugar-alcohol like xylitol or erythritol but many people notice digestive disturbances with these sweeteners.
