I’ve made this for potlucks (sneakily keto!) and late-night cravings alike. It never disappoints.

Ingredients for Keto Peanut Butter Fudge

Okay, let’s talk ingredients – and the best part? You only need five simple things to make magic happen. Here’s what you’ll grab:

• 1 cup natural peanut butter (unsweetened, and give it a good stir before measuring – that oil separation is totally normal!)
• 1/2 cup coconut oil (melted – I just zap it for 20 seconds in the microwave)
• 1/4 cup powdered erythritol (or your favorite keto sweetener – we’ll talk subs in a sec)
• 1 tsp vanilla extract (the real stuff, not imitation – trust me on this)
• Pinch of salt (just a tiny bit to make all the flavors pop)

Ingredient Substitutions & Notes

Got allergies or ran out of something? No sweat. Here’s how to tweak it:

• Nut-free? Swap peanut butter for sunflower seed butter (just know it’ll turn slightly green when frozen – weird but harmless!)
• Sweetener swaps: Powdered works best, but if using liquid stevia, start with 10 drops and taste as you go
• Coconut oil haters? Butter works too, but your fudge will be softer – still delicious though!

Pro tip: If your peanut butter is super thick, warm it slightly for easier mixing. Just don’t make it hot or it’ll melt your sweetener!

How to Make Keto Peanut Butter Fudge

Alright, let’s get to the fun part – making this dreamy fudge! I promise it’s so easy you could do it half-asleep (not that I’ve tested that theory…). Just follow these simple steps, and you’ll have creamy perfection in no time.

Step 1: Prepare the Baking Dish

First things first – grab an 8×8 inch baking dish (or any small dish you have) and line it with parchment paper. Leave some overhang on the sides – this little “handle” will make lifting your fudge out SO much easier later. No parchment? A quick spray of coconut oil works in a pinch!

Step 2: Mix Ingredients

Now the magic happens! Dump all your ingredients into a medium bowl – peanut butter, melted coconut oil, sweetener, vanilla, and that pinch of salt. Stir gently but firmly until everything’s smooth and glossy. You’ll know it’s ready when there are no sweetener lumps left and it looks like liquid gold. Don’t overmix though – we’re making fudge, not peanut butter soup!

Step 3: Freeze and Serve

Pour that gorgeous mixture into your prepared dish and pop it in the freezer. Set a timer for 1 hour – no peeking! When it’s firm, use the parchment handles to lift it out. Pro tip: Run a sharp knife under hot water before slicing for clean, crumb-free squares. Then try not to eat them all at once (good luck with that!).

Tips for Perfect

Storage & Serving Suggestions

Here’s the scoop on keeping your keto peanut butter fudge at its best! For daily snacking, store it in the fridge where it stays firm but still sliceable. If you’re making a big batch (smart move!), the freezer is your friend – just thaw for 5 minutes before serving. My favorite way? Let it sit out for 10 minutes so it hits that perfect “just slightly cool” temperature where the flavors really shine. Pro tip: Layer pieces between parchment paper in an airtight container to prevent sticking!

Keto Peanut Butter Fudge Nutritional Information

Let’s talk numbers – because yes, you can have your fudge and eat it too! Based on my favorite brands, each luscious square comes in at:

• 120 calories – perfect for guilt-free indulgence
• 3g net carbs – hello, keto-friendly!
• 11g healthy fats – thanks to that peanut butter and coconut oil combo

Remember, exact numbers will vary slightly depending on your specific ingredients. I always recommend checking your peanut butter’s label – some brands sneak in extra carbs! But no matter what, this treat stays firmly in keto territory.

Frequently Asked Questions

I get asked about this keto peanut butter fudge all the time – here are the answers to the most common questions!

Can I Use a Different Sweetener?

Absolutely! Powdered erythritol works best texture-wise, but monk fruit blend or stevia work too. Just know liquid sweeteners might make your fudge softer. My golden rule? Always taste as you go – some sweeteners are stronger than others!

Is This Recipe Dairy-Free?

You bet! The coconut oil base keeps it completely dairy-free. No butter, no cream – just plant-based goodness that still tastes indulgent.

How long does it last? About 2 weeks in the fridge (if it lasts that long!) or 3 months frozen. Can I use almond butter? Yes! Just know it’ll change the flavor slightly. Why is my fudge crumbly? Probably needed more mixing – or your peanut butter was too dry. Next time, add an extra tbsp of coconut oil!
