Tips & Substitutions

To achieve the perfect consistency for your fudge, ensure you reach the soft ball stage while boiling the sugar, milk, and oleo. If your fudge is too soft, try adding a bit more sugar during mixing. For a nutty twist, consider adding chopped nuts or using crunchy peanut butter. If you're out of oleo, unsalted butter can be a suitable substitute.

Storage & Reheating

Store any leftover fudge in an airtight container at room temperature for up to a week.

Frequently Asked Questions

Can I use a sugar substitute in this recipe?

While traditional sugar is essential for achieving the right fudge texture, you can experiment with sugar substitutes designed for baking. Keep in mind that the results may vary, and you might need to adjust other ingredients to maintain the right consistency.

What can I do if my fudge doesn't set properly?

If your fudge doesn't set, it may not have reached the correct temperature during cooking. You can reheat the mixture gently, ensuring to bring it back to the soft ball stage before pouring it into the pan again. Adding a bit more sugar may also help thicken it.

Is there a vegan alternative for this fudge?

To make a vegan version, substitute the oleo with a plant-based butter and use coconut milk instead of regular milk. Ensure your peanut butter is also free from animal products. The fudge will still be delicious and rich without compromising on flavor.
