This 5 Ingredient Microwave Salted Caramel Fudge is exactly that kind of magic—simple, fast, and incredibly indulgent.

I remember the first time I tried a homemade fudge recipe. It was a rainy Sunday, and my younger self was tasked with “helping” in the kitchen. Half an hour later, our countertop looked like a sticky battleground, but the reward was worth every splatter. This recipe takes that nostalgia and simplifies it even further. In just ten minutes (yes, you read that right), you can have rich, creamy fudge ready to set in the fridge. It’s perfect for those times when you want a quick treat without compromising on flavor.

What I love most about this recipe is its versatility. Whether you’re making it for a last-minute gift, a spontaneous snack, or a special occasion, it never fails to impress. The salted caramel twist balances sweetness with a hint of savory, making every bite a little adventure for your taste buds. Plus, with only five ingredients, it’s incredibly approachable—even for beginners who might be intimidated by traditional fudge-making techniques.

If you’ve ever been intimidated by fudge recipes that require constant stirring over the stove or complicated candy thermometers, this recipe is your ticket to a stress-free, sweet success. Whether you choose the quick microwave method or prefer using a Thermomix for precise control, you’ll end up with decadent, melt-in-your-mouth squares that taste like they took hours to perfect.

Cooking Tips and Substitutions

1. Chocolate swaps: If white chocolate isn’t your favorite, feel free to use milk or dark chocolate, but keep in mind the flavor profile will change.

2. Salted or not: The pinch of sea salt enhances the caramel notes, but you can skip it if you prefer a purely sweet fudge.

3. Microwave caution: Microwaves vary, so check every 2 minutes to avoid burning. Stirring ensures even melting.

4. Thermomix alternatives: If you don’t own a Thermomix, the microwave method works just as well and is less fussy.

FAQ

Q1: Can I make this fudge vegan?
A: Yes, swap butter for a plant-based alternative and use sweetened condensed coconut milk instead of regular. Chocolate must also be dairy-free.

Q2: Can I reduce the sugar?
A: Slightly, but it may affect the texture. Fudge relies on sugar for structure, so large reductions aren’t recommended.

Q3: Can I use granulated brown sugar?
A: Not recommended. Soft brown sugar gives the fudge a creamy texture and prevents graininess.

Q4: Do I have to use a rectangular slice tin?
A: No, any shallow dish works. A square or round dish will still yield great fudge—just adjust cutting sizes accordingly.
