I've made this recipe several times and love how delicious and simple it is. I cut mine into 16 pieces instead of 12 and this is plenty for when I want a bite of something sweet.
I wanted to share a variation I made today - White Chocolate Coconut Raspberry fudge!
I used white chocolate chips, full fat coconut milk instead of heavy cream, shredded unsweetened coconut instead of nuts, and topped the whole thing with freeze dried raspberries, more shredded coconut, and Maldon flaky sea salt. Delicious and pretty!
PS: Pro tip - brown your butter! I discovered this by accident and it tastes DIVINE.
Jennifer Banz says
Sounds amazing!
Carol M says
This is such a simple recipe and tastes fabulous. I’ve made this several times now and sprinkled sea salt on the top which just adds to this amazing fudge.
Tanya says
Can I use powdered allulose instead of erythritol?
Jennifer Banz says
Yes, that will work!
Debi says

Maggie says
Without nuts, how many net carbs? It looks delicious.

Joanh says
Can u sub almond milk for hwc
jenniferbanz says
You could try, it may work
Debbie says
I've made this several times, I think it's the best recipe I've found for "real" fudge.
Kathy says
This is a very simple recipe. I add a teaspoon of vanilla or other flavoring. Since the recipe calls for cutting it in smaller pieces so I can eat several pieces. I store it in a ziplock bag in the refrigerator.
Lou Darrah says
This is delicious. Maybe too good????
Kim Darnelll says
Can you freeze this fudge? And if so for how long ? Thanks you in advance?
jenniferbanz says
Yes definitely! I would freeze for up to 2 months
Christine says
Wouldn't last long enough to freeze in my house!
Ro says
Oh my goodness! Just made this with Lily’s dark chocolate chips and black walnuts. Best bite I’ve had in months....and I just scraped some out of the pot after freezing the recipe....about a teaspoon full. And yes, I wanted to eat the whole pan full - but refrained. ???? I highly recommend this recipe. I bet it would be scrumptious with a bit of orange zest and pistachios!
Kelli M says
