Pumpkin Patch Fudge
This is a nostalgic one for me. I remember going to the pumpkin patch as kids to pick out a pumpkin. The best part was getting fudge as a special treat. There’s just something so rich, so decadent about fudge. I love(d) that soft, sugary, chocolatey bite. Tiny bits of crystallized sugar that are almost crunchy, then dissolve instantly—who knows what I’m talking about?
This is based on my Mom’s easy microwave fudge—with all the low-carb swaps and twice the nostalgia. Of course, we’re going sugar free here—but you can expect full fudge satisfaction—with special thanks to Lily’s chocolate baking chips and the real sugar taste of today’s sweeteners (I prefer Swerve and Latanko.)
I love that I can whip up a batch of low carb fudge any time I like (because I’m a grown up!) I also love that it always still reminds me of those pumpkin patch days.
I’ve got plenty more ways to customize this treat too—so whichever (inner!) kid or grown up you have in mind—you’ll be sure to find your favorite fudge. 🎃🍫 – Linds x
Ingredient Notes
5 ingredients are all you’ll need to make this keto fudge recipe. Here are a few you may have questions about:
- The chocolate: You can make your own chocolate (check out my sugar-free recipe here) or grab a bag of Lily’s chocolate chips, which TBH is what I always do. Best prices at Walmart!
- The sweetener: I prefer Swerve/Lakanto as keto sweeteners. Both can be used as a 1:1 swap with traditional sugar. If you’re using a different brand of erythritol, you may want to increase the amount added, as it’s 70% as sweet as sweet
Psst – I prefer to make low carb fudge with chocolate chips (rather than keto fudge recipe with cocoa powder), as the chips give you a softer, fluffier texture — cocoa powder absorbs liquid and dries recipes out.
Low Carb Fudge Mix-Ins
- Chopped nuts – use your faves! My pick? Walnuts or pecans.
- Coconut, shredded + unsweetened
- Freeze-dried keto fruits, like strawberries or raspberries
- Keto peanut butter – check out my keto peanut butter fudge and consider swirling the 2 together.
- More chocolate! Stir in some sugar free white chocolate chips, or any of Lily’s flavors.
How to Make Keto Fudge:
- Microwave chocolate chips, heavy cream, and butter together at 50% power using 30-second intervals. Stir and repeat until the ingredients melt together completely. (Note: this can also be done in a double boiler, or a heat-safe bowl nestled over a saucepan with water)
- Add the sweetener, vanilla, and any mix-ins. Stir to combine.
- Pour keto chocolate fudge mixture into an 8×8 baking dish lined with parchment paper and smooth out the top.
- Toss in the refrigerator until set, at least 3 hours. (Speed up the process by placing your keto fudge in the freezer). Slice and enjoy!
Storing Sugar Free Fudge
Stash your sliced fudge in the fridge, OR (bonus points) in the freezer! If freezing, thaw in the fridge before digging in.

Lindsey's Tips
- Chocolate - I love Lily's chocolate chips for this fudge.
- Sweetener - This recipe was measured with Lakanto or Swerve. If using a different brand of erythritol, know that they're often 70% as sweet and you'll want to adjust accordingly. A simple taste test will do the trick!
- Mix-Ins Ideas! (Optional + not included in nutritional info):
- Keto marshmallows
- Freeze-dried fruits
- Shredded and unsweetened coconut
- Additional chocolate chips
- Microwave or stovetop - You can melt the butter and chocolate chips together using a double boiler instead. I use a heat-safe bowl nestled into a saucepan full of water.
- Nutritional information is based on 1 piece if you cut this fudge into 16 pieces. It was calculated using Lily's chocolate chips:

Felicia
Hi. Do you know what the net carbs would be? Fiber was not included in the nutrition facts. Thanks!
Lindsey
Hi Felicia! I’m SO sorry about that, looks like I was having trouble with my recipe plugin and the fiber wasn’t displaying! All is fixed now and the information is in there 🙂 Hope you enjoy and let me know if you have any other questions 🙂
Candy
What can you use in place of the protein powder?
Lindsey
Hi Candy! I tested out a bunch of recipes without protein powder, but didn’t get the measurements down perfectly, so wouldn’t be able to recommend a tested swap! You could try cream cheese? It may not set as well, but it’d be tasty 🙂
Alex
YUM! is this really low carb? so goood!?
Lindsey
Hehe yes! I’m so glad you enjoyed it Alex!?
Nancy Gwynn
OMG is this delicious!!! I can hardly believe they are sugar free!!! I used Splenda simply because that is what I had on hand, and wow…..what a great dish!! But then, I have never been disappointed in any of your recipes. Not too sure I will make the nano bread again, but the hamburger and hot dog rolls are a big hit at our house!. You are such a blessing to those of us trying to stay healthy in an unhealthy world. Even my diabetic husband can enjoy!!!
Lindsey
Yahoo! Thank you so much for the kind words Nancy! That means a lot ? I am so glad you and your family enjoyed!?
Julie
Hi Lindsey, I made your fudge recipe this weekend and wanted to thank you for a very good low-carb recipe! I have a few comments: 1) This recipe makes a generous pan of fudge! My pan must be 8×8, because the pieces are so thick. Love it!
2) In step 3 you say, “Microwave on high for 1 1/2 minutes at 50% power.” This confused me a little – HIGH power is typically 100% power, not 50%. I went ahead with the 50%, but think for the first 1.5 minutes, it could use 100%. Could this be a typo?
3) IMO, cinnamon and chocolate are a winning team! If I use chocolate in a recipe, it’s usually always followed up with cinnamon.
4) Once I started baking/cooking, I was taught that salt is a flavor enhancer. Hence, this recipe got a pinch of salt, as well.
I’m sure the recipe was good as printed. Thank you for allowing me to enjoy fudge again!!!
Lindsey
Hi Julie! Thank you so much for your notes! Yes, you are correct, “high” was a typo, as 50% is not high ? And YES! I usually add a pinch of salt to my chocolate recipes as well, great suggestion! I’ll definitely have to try the cinnamon as well next time. Thanks for the kind words, and I’m so so happy you enjoyed ❤️❤️❤️
