All quantities and full instructions are in the recipe card below.

Pumpkin puree – fresh pumpkin puree or pumpkin pie filling will work in this pumpkin fudge. Ensure whichever pumpkin puree you use is low moisture, otherwise, the pumpkin fudge recipe will not set.

Expert recipe tips

Why doesn’t my pumpkin pie fudge set?

You may have overheated the fudge or may have accidentally used a spreadable or lite, low-fat cream cheese. These will not set the fudge. You would have to freeze it, to ensure it is firm enough to be cut with a knife.

Why has my fudge separated?

Do not overheat the cream cheese or it will split and separate. Just heat gently, so the butter and cream cheese mix together beautifully. If it has separated, allow the fudge to cool, and as the butter begins to set, stir the mixture back together. Stir again to emulsify before pouring into the lined baking dish.

Do I need to boil the fudge?

No. If the cream cheese and butter are heated too high, they will begin to separate. Only warm enough on low heat to melt the butter and cream cheese together.

Can I make this pumpkin pie fudge dairy-free?

No, this particular recipe is based entirely on dairy products such as butter and cream cheese. However, you may enjoy dairy-free chocolate Bounty bars (coconut bars) instead of this low-carb fudge.

Which sweetener is best for fudge?

You can use a granulated sweetener but a powdered sweetener will give a smoother texture.

Can fudge be frozen?

This sugar-free fudge recipe can be frozen for up to 3 months in an airtight container.

How do you harden fudge?

To set the fudge quickly, place the fudge in the freezer for 20 minutes.

Which container is best for fudge?

It is easiest to set the keto fudge recipe in a square baking dish that has been lined with baking parchment paper, making it easy to remove the fudge squares.

However, any type of baking pan will work such as a round cake tin, loaf pan, or loose bottom tin.
