FAQs
Can I use low-fat cottage cheese?
Yes, I can use low-fat cottage cheese, but the texture may be less creamy compared to using full-fat cottage cheese.
Is this fudge suitable for diabetics?
This fudge is low in carbohydrates and sugar-free, making it suitable for many diabetics. However, I always consult with a healthcare provider to ensure it fits my dietary needs.
Can I make this fudge dairy-free?
To make a dairy-free version, I substitute the butter with coconut oil and use a dairy-free cottage cheese alternative. Keep in mind that this may alter the taste and texture.
How can I make the fudge sweeter?
If I prefer a sweeter fudge, I add more of my favorite low-carb sweetener to taste during the blending process.
What can I use instead of a loaf pan?
If I don’t have a loaf pan, I use any small baking dish or even silicone molds to shape the fudge. I adjust the cutting size accordingly.
