What Makes This Recipe So Good

• Ridiculously fast: We’re talking 10 minutes of hands-on time. The freezer does the rest.
• Ultra-chocolatey: Cocoa powder and sugar-free chocolate team up for big flavor without the sugar crash.
• Keto-friendly: Sweetened with erythritol or allulose, not your willpower.
• Foolproof texture: Coconut oil + nut butter = silky, sliceable, melt-in-your-mouth fudge.
• Customizable: Walnut crunch? Espresso swirl?

  Sea salt flake moment? Yes to all.

Ingredients

• 1/2 cup coconut oil (refined for no coconut taste, unrefined if you like a hint of coconut)
• 1/2 cup unsalted butter (or ghee for dairy-sensitive)
• 3/4 cup unsweetened creamy nut butter (almond, peanut, or sunflower seed for nut-free)
• 1/2 cup unsweetened cocoa powder (Dutch-processed for a smoother, deeper chocolate)
• 1/2 to 3/4 cup powdered erythritol or allulose (adjust to taste; powdered dissolves better)
• 1 tsp vanilla extract
• 1/4 tsp fine sea salt
• 3 oz sugar-free dark chocolate, chopped (optional but awesome for extra richness)
• Optional add-ins: 1/2 cup chopped walnuts or pecans, 1–2 tbsp sugar-free mini chips, 1 tsp instant espresso, 1–2 tbsp shredded unsweetened coconut, flaky sea salt for topping

Cooking Instructions

1. Line the pan: Use an 8×8-inch square pan lined with parchment, leaving overhang for easy lift-out. This saves your sanity later.
2. Melt base fats: In a saucepan over low heat, add coconut oil and butter.

   Stir until fully melted, not sizzling. We’re warming, not frying.

3. Whisk in nut butter: Add nut butter and whisk until smooth and glossy. If it looks grainy, lower the heat and keep whisking.
4. Add chocolate power: Stir in cocoa powder, sweetener, vanilla, and salt.

   If using chopped sugar-free chocolate, add now and whisk until fully melted.

5. Taste test: Off heat, taste for sweetness and salt. Adjust with a little more powdered sweetener or a pinch of salt. Balance = magic.
6. Customize: Fold in nuts, coconut, or espresso if using.

   Keep chips for the top if you want that bakery look.

7. Pour and level: Transfer the mixture to the lined pan. Smooth the top with a spatula. Sprinkle with flaky sea salt or chips.
8. Chill to set: Freeze for 30–45 minutes or refrigerate 2–3 hours until firm enough to slice.
9. Slice smart: Lift out by the parchment, place on a cutting board, and slice into 25 small squares (or 16 gigantic ones—your call).
10. Serve: Let sit at room temp for 2–3 minutes before eating for peak fudginess.

How to Store

• Fridge: Store in an airtight container up to 10 days.

  Layer with parchment to prevent sticking.

• Freezer: Freeze up to 3 months. Thaw a few minutes at room temp before serving.
• Travel tip: Keep chilled if you’re taking it to a party. It will soften in warm rooms because, you know, coconut oil.

Why This is Good for You

• Low in net carbs: Using sugar substitutes keeps blood sugar steady and cravings quiet.
• Healthy fats: Coconut oil and nut butter deliver satiating fats that help you feel full longer.
• Cocoa perks: Cocoa is rich in polyphenols, which support cardiovascular health and mood.

  Chocolate that likes you back? Yes, please.

• Portion control built-in: Dense, rich squares mean satisfaction with less—no need for a second plate (IMO).

Common Mistakes to Avoid

• Overheating the mixture: If it bubbles, you’re too hot. Overheating can split the fats and mess with texture.
• Using granular sweetener: Grainy equals gritty.

  Use powdered sweetener for a smooth finish, or blitz granules in a blender.

• Skipping salt: A pinch of salt amplifies chocolate flavor. Don’t fear it.
• Wrong pan or no parchment: Greased-only pans can still stick. Parchment is the cheat code.
• Cutting too soon: Let it set fully or you’ll get smears and sadness.

  Patience = clean edges.

• Storing at warm temps: This fudge softens quickly. Keep chilled unless you like chocolate finger paint.

Alternatives

• Dairy-free version: Replace butter with more coconut oil or cacao butter. Use dairy-free sugar-free chocolate.
• Nut-free version: Use sunflower seed butter or tahini.

  Both give creaminess with unique flavor.

• Allulose vs. erythritol: Allulose is smoother and less cooling. Erythritol is more common but can have a cooling aftertaste—your call.
• White “keto” fudge: Use cacao butter instead of cocoa and add vanilla bean paste. Add macadamias for a luxe vibe.
• Mocha fudge: Add 1–2 tsp instant espresso and a pinch of cinnamon.

  Coffee makes chocolate taste more chocolatey—science and sorcery.

• Mint-chocolate: Add 1/2 tsp peppermint extract. Top with crushed, sugar-free peppermint if you’re feeling festive.
• Protein boost: Whisk in 1–2 scoops chocolate or unflavored whey isolate. If it thickens too much, loosen with 1–2 tbsp warm coconut milk.

FAQ

Is this fudge actually keto?

Yes.

It uses low-carb sweeteners and high-fat ingredients, keeping net carbs low. Always check labels on sweeteners and chocolate—some “sugar-free” products hide maltitol, which can spike blood sugar.

Can I make it without coconut oil?

You can replace coconut oil with butter, ghee, or cacao butter. Note that coconut oil helps it set firmly; with only butter, the fudge will be softer and best kept very cold.

Why is my fudge gritty?

You likely used granular sweetener or didn’t fully dissolve it.

Use powdered erythritol or allulose, and whisk over gentle heat until the mixture looks glossy and smooth.

How do I prevent the cooling aftertaste?

Use allulose or a blend of erythritol and stevia/monk fruit to smooth the finish. A little extra vanilla and a pinch more salt also reduces that “cooling” sensation.

Can I make this in the microwave?

Yes. Melt coconut oil and butter in 20–30 second bursts, stirring between.

Whisk in nut butter, cocoa, sweetener, and flavorings until smooth. Don’t overheat or it can separate.

What size servings should I cut?

For rich fudge, 1–1.5-inch squares are ideal. From an 8×8 pan, that’s about 16–25 pieces.

Start small; it’s very satisfying, FYI.

Will this set without chilling?

Not really. The fats need the cold to firm up. The fridge works well; the freezer just speeds things along.

Wrapping Up

This is the keto dessert you’ll “just whip up” and then accidentally become famous for among friends.

It’s fast, flexible, and delivers a rock-solid chocolate fix without the sugar drama. Keep a batch in the fridge for emergency snacks, classy after-dinner bites, or those 9 p.m. “I deserve something” moments. One bowl, no bake, all reward—exactly how chocolate should be.
